As a web3 developer working on Ethereum blockchain, you've likely come across the problem of trying to retrieve historical data. Traditional methods involve manually scanning through blocks and transactions, which can be slow and tedious. Imagine having to sift through thousands of blocks and interactions just to find the information you need. Yet alone, multiple blockchains!

While eth_getLogs can be an option for devs to make sense of the blockchain data on Ethereum, what if there was a way to easily and quickly retrieve log entries that match specific filter criteria across eight different blockchains? This is where **ankr_getLogs** comes in.

## Releasing ankr_getLogs

As a developer, you need efficient and accurate ways of retrieving historical data to make informed decisions and implement your business logic. ankr_getLogs offers a solution to this problem by providing an easy and fast way to access historical data on the Ethereum blockchain and seven other chains, including:

- Polygon
- BSC
- Fantom
- Avalanche
- Syscoin
- Optimism
- and Arbitrum

## Getting the Most Out of ankr_getLogs?

**ankr_getLogs** is a JSON-RPC method that allows for the retrieval of log entries that match specific filter criteria. It makes it possible for you to retrieve log entries with ease and speed. 

Log entries are a way for smart contracts to record events that have occurred on the blockchain. When a contract emits an event, it creates a log entry that contains information about the event. This can include things like the **contract address**, the **event name**, and any **indexed parameters**. Log entries are important because they provide a way for external parties to track what is happening within a contract and to respond to events that occur.

### Retrieving Event Logs

With ankr_getLogs, the method takes parameter, a filter object that defines the criteria for the log entries to be returned. This filter object can include properties such as the **address of the contract**, the **topics** of the event, and the **block range** in which the log entries were generated.

### Decoding the ankr_getLogs Response: Understanding the Data Returned

The ankr_getLogs method returns an array of log entries that match the filter criteria. Each log entry is represented as an object with properties such as **transactionHash**, **blockNumber**, **logIndex**, **address**, **data**, and **topics**. Understanding these properties and how to interpret the data they contain is crucial for making the most out of the ankr_getLogs method.

![carbon (7).png](/uploads/carbon_7_5312b20d26.png)

The **transactionHash** property contains the transaction's hash that created the log entry. This can be used to look up the transaction and get more information about it. The **blockNumber** contains the block number in which the log entry was included. This can be used to look up the block and get more information about it. The **logIndex** property is the index of the log entry within the block.

The **address** property points to the address of the contract that emitted the event. The **data** property contains the non-indexed data associated with the event. And the **topics** are the indexed data associated with the event, which can include the event name and indexed parameters.

## Query ankr_getLogs

Now that you have all the necessary tools, you can build and implement the **ankr_getLogs** method into your projects. The ability to quickly and easily retrieve log entries greatly enhances your project's capabilities and allows you to make more informed decisions. 

Don't wait any longer; query [ankr_getLogs](https://www.ankr.com/docs/advanced-api/specification/#tag/Query-API/paths/~1?ankr_getLogs/post) today!

AppChains empower builders to create Web3 apps with best-in-class performance on top of the custom-built blockchain of their choice. However, when creating a project, it’s often hard to figure out where to begin. This task is even more difficult when dealing with a new area of expertise – especially in the constantly evolving world of Web3. With Ankr’s building blocks that help guide the process, it’s easier than ever to transition from concept to product.

Ankr built the AppChain configurator to help projects outline the best possible blockchain for their app in minutes before the AppChain machine gets to work creating it. This kickstarts the building process and allows developers to envision a clear path to their ideal app.

None of the specifications in the configurator are set in stone. However, by the end of the process, the builder will have a better understanding of the specifications available to them. The team at Ankr can then review the developer’s needs, and prepare to build the best AppChain solution for them.

**[Get started now →](https://chainscanner.xyz/ankr/configurator/)**

## Select Your Blockchain Ecosystem

The first step of the AppChain configuration process is choosing an ecosystem to launch your new chain on, like Polygon Supernets or BNB Application Sidechains. Ankr is the trusted AppChain infrastructure partner for these networks that want to welcome a growing family of ecosystem dApps.

## Choose Your Infrastructure

The new configurator also allows developers to choose how many validators they’ll need, full (RPC) node requirements, bridge solutions, Advanced APIs, and more. They can also choose a variety of infrastructure specs like silent signing wallet capabilities or integrated liquid staking that make for seamless user experiences.

![infra.png](/uploads/infra_e67e02daa3.png)


## Pick Custom Features

Once you’ve taken care of all your needs for infrastructure, you have the option to pick advanced options that are tailored to your app, like Ankr’s Gaming SDK, NFT marketplace capabilities, and more. These tools make it drastically easier to build every facet of your dApp that will excite users.

Building on the “privacy hub for Web3” just got a lot easier with Ankr’s RPC connection and gateway to communicate with the Secret Network blockchain.

Secret Network has made waves in the blockchain space with its Layer 1 blockchain and a relatively mature ecosystem of privacy-preserving applications. Its privacy-first focus has skyrocketed network activity after striking several strategic partnerships in 2022.

We see the current moment as the best time to add Secret Network to Ankr’s expanding RPC service. Users can now access Secret Network Public and Premium RPCs, make request calls, and receive information returns that mirror the results they would get by running a Secret Network full node on their own.

## What is Secret Network?

Secret Network, the first blockchain with data privacy by default for smart contracts, enables users to create and use permissionless and privacy-preserving applications. This one-of-a-kind functionality protects users, secures applications, and enables hundreds of never-before-imagined Web3 use cases.

Secret Network is based on the Tendermint SDK, which provides interoperable privacy across the entire Cosmos network. It combines Intel SGX (Software Guard Extension) and Trusted Execution Environment technology, as well as several encryption schemes and novel private key management for network users.

Intel SGX divides the protocol into two sections. The security component is in charge of processing sensitive data via the TEE (Trusted Execution Environment) technology algorithm, which an ordinary person may encounter, for example, when unlocking his smartphone with his fingerprint.

The network, which was first launched on mainnet in February 2020, is supported by dozens of independent development companies (including the SCRT Labs core development team), world-class "secret node" operators, and thousands of Secret Agents worldwide who are working to advance the cause of data privacy for the decentralized web.

## What is The Secret Network Public RPC?

- The RPC (Remote Procedure Call) of the Secret Network connects your wallet, command-line interface, or dApp to the Secret Network blockchain. It functions as a blockchain messenger or router, relaying on-chain information between nodes, dApps, and end users.
- Ankr's Secret Network RPC endpoints are a gateway for developers to interface directly with the Secret Network chain — a portal to communicate easily, remotely, and without the DevOps of setting up their own Secret Network nodes.
- Ankr offers a geo-distributed and decentralized Secret Network RPC composed of many independent blockchain nodes running globally for low latency and extremely reliable connections.
- It can be used by anyone, anywhere, at any time, without requiring an email address, a credit card, or any other personal information.

## What are the Benefits for Developers?

Ankr's RPC service offers a simple and straightforward resolution to the following challenges developers face:

- Eliminating difficult node operations — As anyone who has tried knows, running a node is not always as simple as it appears. The Ankr public RPC removes the need for many developers to set up their own Secret Network node, saving them hours of time building, calibrating, and troubleshooting node issues.
- Providing access to advanced tools — Ankr provides the best tools for those who want to build with Secret Network in order to build applications quickly. Those who purchase the Ankr Protocol Premium version will have immediate access to:

*Unlimited Secret Network requests*

*Global node distribution*

*Private Secret Network endpoints*

*Prioritized requests*

*WebSockets (WS) capabilities*

- Powering apps and open-source software that require Secret Network access — Connect to a cluster of high-performance nodes that contain the data required to build and run dApps with Secret Network chain capabilities.
- Strengthening the Secret Network network globally by allowing for easier development and a larger, decentralized node infrastructure. Ankr will incentivize independent and enterprise Secret Network node operators to add their nodes to the load balancer in exchange for ANKR tokens, resulting in a larger network with many more Secret Network nodes.

## What is Next for Ankr’s RPC Service?

Ankr Protocol is just getting started with decentralized infrastructure, and we intend to add support for a growing number of chains in the future. Ankr’s unique and important interface aggregates so many access points and tools in one place, allowing developers to build a truly multi-chain future.

We are currently developing RPC capabilities for many more chains, which will be available on our dashboard, which will house all of our public RPC endpoints with one-click wallet connections, chain activity, analytics, and more to come.

When it comes to choosing how to connect their projects with blockchain data, most developers want the option that provides the highest performance possible – but for projects with a limited budget, it helps if that service comes with an affordable price tag. Ankr provides all services with our community of developers in mind first and foremost. This is why we’ve positioned our core RPC service to be **the highest quality and most affordable option available to Web3 builders.**

## Predictable Pay-As-You-Go Pricing Ensures You Never Overpay

Most RPC/API service providers have a pricing system based on daily request limits with a monthly subscription plan. Often, the price of each RPC request call is estimated differently in how much processing power it consumes in “compute units,” making it difficult to anticipate how quickly your monthly compute unit allotment will run out. If it does run out, you will most likely need to pay overages which can be quite costly (in addition to your subscription). This all leads to a customer experience that makes it more confusing for builders in knowing what their monthly costs will be as they frequently pay for more than they use.

**However, Ankr’s Premium RPC plans are much more predictable, powerful, and affordable.**

- Pricing per request method is the same for all EVM-compatible chains
- Pay-As-You-Go per RPC request ensures no overpayment from a subscription
- Option to pay in crypto for any service tier
- 1,500+ requests per second regardless of compute units (upgradeable on request)
- No limit to how many of your apps use the service
- Option to sign in with a Google account or Ethereum Wallet and pay with a credit card

**Visit our [pricing page](https://www.ankr.com/rpc/pricing/#premiumBlock) for more info.**

## Pay Less for Flexible Plans That Scale With You

Ankr has created our pricing system to be as stable and cost-effective as possible for our users. The price of Ankr’s API Credits is always pegged to USD. And when using ANKR tokens for Pay-As-You-Go plans, ANKR automatically calculates API Credits at the latest ANKR/USD exchange rate. However, many users like the simplicity of credit card payments, and you can see prices in USD clearly in the chart below.

In either payment method (ANKR or USD), it is much easier to anticipate what your daily, weekly, and monthly costs will be. That’s because request type prices are greatly simplified, and users will be able to gauge their usage costs easily once they know their average daily requests per EVN/ non-EVM chains. **And the best part is, if your usage is down, your costs will fall as well. You won’t have a set monthly cost or additional fees waiting for you.** And no worries, if you run out of credits – your account wouldn’t be suspended, it will just convert to the free plan, and your Premium benefits will be reactivated immediately after the payment.

![Pricing.png](/uploads/Pricing_e44f74914b.png)

Our PAYG pricing model:

0.10 USD = 1M API Credits

**Learn more about our pricing in the [Ankr Docs](https://www.ankr.com/docs/).**

## Affordable, Developer-First Pricing Saves You Money

Ankr provides developer-first pricing for Premium RPC services at competitive rates across all supported chains (more than any other provider). More than that, we are transitioning to a model that shares all RPC revenue with independent node providers, creating a more collaborative and decentralized way to serve blockchain traffic.

The graph above shows a price comparison of how much it would have cost SpiritSwap to make 8,590,000,000 requests using each provider (a real monthly figure for their usage of Ankr’s RPCs). We used SpiritSwap as an example because their large scale of multichain traffic makes it especially important for them to save on infrastructure. You can see that Ankr charges drastically lower rates than our main competitors.

![736_-_Centralized_vs_Decentralized_Pricing_at_Scale.png](/uploads/736_Centralized_vs_Decentralized_Pricing_at_Scale_9bbfbd2efb.png)

*Estimated price comparison from May 2022*

## Easier Payment Methods Save You Time and Effort

Ankr is a Web3-native organization, but many of our users will love the simplicity that comes with logging on via their Google account. New users can sign up and log in with Google authentication as an easy way to get started and top up their account balances with a credit card. Additionally, those who create an account with a wallet like MetaMask now use credit cards as a payment method.

- Create an account easily with Google
- Pay using your credit card (accepting the most common global credit and debit cards)
- Access all the ease of use and security features of Google

**[Create a new account](https://www.ankr.com/rpc/pricing/) in two clicks with Google.**

## Never Sacrifice Performance for Affordability

Ankr isn’t just leading the pack in pricing. Our RPC services have consistently outperformed the competition in every area developers care about:

- Latency
- Reliability
- Supported Blockchains
- Global Distribution
- User Experience
- Decentralization

**We’ve broken all of it down here – see [where Ankr stands in performance](https://www.ankr.com/blog/ankr-leads-the-pack-in-rpc-api-services/).**

Why Use Ankr? Big Savings On High Performance RPC Services

![cs.jpg](/uploads/cs_5a16c415de.jpg)

**The UI of [Ankr AppChains](https://www.ankr.com/app-chains/) offers Web3 developers a readymade solution for every interaction their users need to have with their new network’s infrastructure. With a complete solution for creating and interfacing with dedicated blockchains, devs can focus on building an application layer unlike anything we’ve seen before.**

## Intro

It’s difficult explaining the benefits of a new technology like blockchain to a world of potential users while getting them as excited as you are about how it’s changing the status quo of everything from finance to gaming. For most people, seeing is believing – especially when it comes to something like their assets. The problem is, Web3 is still creating a pleasing user interface for all the ways we interact with decentralized systems, including the infrastructure behind the applications.

We need block explorers like Etherscan to see the status of transactions, sites like CoinMarketCap to get a view of token data, sites like Ankr Staking to stake crypto, and sites like Snapshot to participate in governance. These tools are a necessity for using blockchain applications, but why do they all need to be in different places? It’s kind of like having to use a different web browser for every different topic you’re curious about.

Ankr has now started solving this problem with the all-in-one user interface for Ankr AppChains: [Chainscanner](https://chainscanner.xyz/ankr/appchains/?network=bas-mapes). This is a tool that allows us to show rather than explain the inner workings and benefits of Web3 while bringing blockchain infrastructure to life in ways we’ve never seen before.

## A New Interface for Blockchain Tech

Blockchain and Web3 tech is frequently compared to the early days of computing and the internet. The internet wouldn’t see any real power until it developed a user interface strong enough to let people *see* just how powerful the internet and computers could be. If we take things all the way back to the 1980s, we find some of the first GUIs (graphical user interfaces) with the initial release of Microsoft Windows and Apple’s Lisa system. Introducing these interfaces became a pivotal moment when computers allowed their users to “visually navigate a virtual desktop, opening graphical ‘windows’ displaying the contents of electronic folders and files.”

![win 95.png](/uploads/win_95_450b1f40cc.png)

(The Windows 95 UI)

In the same way, Chainscanner provides a window into all of the AppChains that are operating on Web3. Just like the first GUIs, Chainscanner allows us to dive into data, information, and tools that were previously much more difficult to extract and play with. This opens up a new world of possibilities.

![CS ui1.png](/uploads/CS_ui1_88ea8954d9.png)

(The Chainscanner UI with Meta Apes Web3 game chosen)

## What Exactly Is Chainscanner? The UI for Ankr AppChains

Ankr AppChains is an ecosystem of application-specific blockchains (sidechains) that were built for Web3 projects by Ankr’s engineering team. within mother-chain environments like [BNB Application Sidechains](https://docs.bnbchain.org/docs/BNBSidechain/overview/bs-overview/), [Polygon Supernets](https://polygon.technology/supernets), and [Avalanche Subnets](https://www.avax.network/subnets). **Chainscanner and the Ankr AppChains product are one and the same. It is akin to the operating system of AppChains** (like Windows is to Microsoft) that allows users to interact with the infrastructure layer that underpins the Web3 applications they are using.

Chainscanner provides a pleasing user interface over the blockchain infrastructure that powers our AppChain projects. The platform's purpose is for developers to view the core infrastructure of a blockchain easily and for consumers of those dApps to understand and visualize the actions available to them. Interacting with Chainscanner allows consumers to be truly involved, knowledgeable, and powerful stakeholders in their favorite applications while giving them the tools to go beyond a position as a speculative or even experienced token holder.

## How Chainscanner Is Changing the Web3 Experience

The platform combines the following capabilities and packages them in one easy-to-use platform for a drastically improved and streamlined Web3 user experience.

- **Block explorer** - Transparently displays all on-chain data.
- **Staking interface** - Allows users to earn staking rewards with their favorite tokens.
- **Validator enrollment hub  Provides onboarding to contribute validator nodes.**
- **Governance portal Lets users vote on app updates and the direction of ecosystems.**
- **Development resource Offers devs testnet tokens, docs, and resources for building.**
- **Information source Provides unique insight into the hosted chains and apps.**

Chainscanner doubles as an environment where users can learn everything they need to know about different chains and dApps before using them – combining CoinMarketCap-like research tools with Etherscan-like functionality. This is an incredibly helpful platform for dApps to showcase their offerings and attract new communities. The bottom line is that the combination of AppChains and Chainscanner is making Web3 more scalable, user friendly, and welcoming to newcomers and vets alike.

## Taking the Burden Off Of Web3 Developers

For Web3 developers, the combination of Ankr AppChains and Chainscanner is incredibly powerful. It provides an end-to-end solution not just for creating their own blockchain but for creating all of the infrastructure that makes it usable like a block explorer, staking interface, and even an easy path to list tokens on exchanges. This lets builders save an enormous amount of effort and hoursso they can focus on creating applications that wow users, gain traction, and climb the dApp rankings.

## Final Thoughts

Chainscanner, in its current state, is like the very first version of Microsoft Windows or any Apple OS. It is a tool that will be iterated on until it is virtually unrecognizable, with endless room for improvement. The future will hold entirely new ways of interacting with AppChains, visualizing data in more attractive ways, contributing independent infrastructure, and many other improvements that are currently unforeseeable. We are incredibly excited for what the future holds and truly unlocking the potential for a user-friendly and utterly powerful Web3.

Chainscanner: Evolving the Web3 User Experience

![Bomb.jpg](/uploads/Bomb_481842d94d.jpg)

The new crypto staking and DeFi platform [BOMB Money](https://www.bombmoney.com/) has just launched a [mobile app](https://www.bombmoney.com/app/) powered by BOMB Chain, its own Binance Application Sidechain built with Ankr AppChains! This is great news for an audience of millions of smartphone users who are interested in earning a higher APR on their digital assets. These new users will find an unrivaled user-friendly staking experience on the BOMB Mobile App powered by the new AppChain.

## Bringing Crypto Staking to All Mobile Users

Traditionally, staking crypto and DeFi earning strategies were only reserved for the tech-savvy and not at all for the faint of heart. Using DeFi protocols and staking was cumbersome, slow, and at times downright dangerous due to hacks and rug pulls. That left high rewards for only those knowledgeable and brave enough to use them. But now BOMB Money is changing DeFi for the better by making staking an easy experience right from your phone:

- Download the BOMB Mobile App and create a wallet in one tap
- Stake assets like BOMB, BTC, and Ethereum easily from your phone
- Earn a high APR (up to 30% APR initially) on your crypto assets

## Powered By Their Own Ankr AppChain

***“We were blown away by how much easier it was to build our vision of BOMB Money with Ankr’s solutions. On our own BAS chain, we have drastically improved our ability to scale. With other infra tools like Advanced APIs making things work seamlessly in the background, we’ve been able to focus on perfecting the user experience and app integration.”***

**– Aaron Shames, CEO, BOMB Money**

The BOMB Money team knew that a solution like this would need to meet the demand of thousands, if not millions, of interested users. In order to serve the whole world with revolutionary earning products, they needed infrastructure that could handle itself on a global scale – that’s where Ankr comes in.

[Ankr AppChains](https://www.ankr.com/app-chains/) is bringing Web3 scalability to new limits by providing a dedicated blockchain for every dApp that seeks a higher-performance environment to launch on. With Ankr’s end-to-end engineering resources to create sidechains or subnets on ecosystems like BNB Application Sidechains, Polygon Supernets, and Avalanche Subnets, it has never been easier to launch dApps on a dedicated chain. The BOMB Money team used our AppChains product for:

- End-to-end engineering support to build a custom app-specific blockchain
- A fully-fledged Binance Application Sidechain to power the BOMB Money app (BOMB Chain)
- A better UX for BOMB Money users with an entire interface for interacting with the BOMB Chain, including a cross-chain bridge solution, block explorer, on-chain data display, and staking UI.

**[Build an Ankr AppChain to power your dApp](https://www.ankr.com/app-chains/)**

## How BOMB Money Is Changing DeFi In All The Right Ways

Launched in 2022, BOMB Money is a DeFi protocol that was the first fork of Tomb Finance. Just as Tomb created an algorithmic token pegged to FTM on Fantom, BOMB wanted to apply this solution to the reigning store of value: Bitcoin. BOMB Money currently offers BTC staking to BTC mainnet users while putting the value of their assets to work on their Binance Smart Chain-based platform, allowing them to provide a higher APY than typical mainnet BTC stakers – a model they are currently expanding to many more chains.

### The BOMB Mobile App Makes High-Yield Staking Accessible To Millions

The revolutionary BOMB Mobile App will break down the barriers to entry for new investors and allow them to set up a fully functional Web3 wallet with just one click. They can then start earning high yields on Bitcoin and other assets either with the fiat on-ramp or by transferring their crypto. This will all be powered by their own proof of delegated stake blockchain – BOMB Chain.

### BOMB Chain Creates Massive Scalability

BOMB Chain is the custom-built blockchain developed by Ankr and the BOMB Money team. The native token, BOMB, is pegged to Bitcoin – the first of its kind. The Delegated Proof-of-Stake blockchain will run the BOMB Mobile App offering fixed-term staking protocols with full transparency and proof of all assets on chain. To celebrate the launch of the new blockchain, until January 9, the first 1 million BOMB locked [via their BOMB Lock Bonus](https://app.bomb.money/bombchain) will receive 1.5x the locked BOMB on BOMB Chain!

**The Ankr team engineered the BOMB AppChain to the custom specs of the team:**

- **Secure:** Ankr’s engineers implemented a powerful delegated proof-of-stake (PoS) consensus mechanism to secure the network. The Ankr team also provided validator setup and deployment while providing an easy-to-use interface where users can stake their BOMB tokens to the chain to help secure the chain.

- **Ultra-fast:** Ankr designed the chain with three-second blocks to provide an ultra-fast and consistent network for the best user experience. The BOMB Chain has high throughput to empower nearly any number of users for the BOMB Mobile App. Additionally, Ankr’s full (RPC) node architecture for BOMB Chain ensures an extremely fast experience when executing tasks like transactions.

- **Transparent:** All assets bridged to BOMB Chain will be verifiable on the chain for complete transparency. Additionally, any user can reference on-chain data and transactions easily via the block explorer on Ankr’s Chainscanner interface (an all-in-one UI for AppChains).

- **Cross-Chain:** All BOMB users can easily access a third-party bridge enabling smooth asset transfers to and from BOMB Chain from networks like Binance Smart Chain and other similar networks. By accessing Ankr’s Chainscanner UI, users can easily navigate to the BridgeHub solution and send and receive tokens with their BOMB Chain wallet address. 

- **Expanding Utility:** Initially powering the BOMB Mobile App, the team has plans to expand the blockchain's ecosystem by enticing builders with grants starting in Q3 2023. Ankr’s RPC node infrastructure will ensure developers have an easy and high-speed connection to BOMB Chain so they can create new applications on top of it.

### Ankr AppChains Delivers Higher Performance for All Web3 Apps

**“*If you’re looking to run a project on your own blockchain, Ankr AppChains is the way to get it built. We were very impressed by the team’s engineering expertise and speed of execution.*”**

**– BOMB Team**

Ankr AppChains are the best way to deliver the highest possible performance for Web3 applications, games, and all other high-throughput use cases. With plug-and-play tools to build your own blockchain and full engineering support from the Ankr team, it has never been easier to have a dedicated network powering your application.

### Innovating for a Growing Web3 Ecosystem in 2023

In the past year, the internet has been rapidly evolving beneath the surface of what most know. With leaps and bounds not just in the decentralized web, but with AI, quantum computing, and new tools – we are headed for an eventual kickstart out of this period of tech hibernation.

Web3 is on the precipice of disrupting the ways people connect, transact, play, and communicate. With major blockchain buy-in from some of the biggest organizations and companies in the world over the past year, we are primed to see an integration of Web3 aligned with our most optimistic expectations.

While we are still in this builder’s market, we are working hard to close the last technical gaps between Web3 and mass adoption. We’re focused on building for builders, and maintaining our foundational value of decentralization as we innovate. This year, we strive to create tools that empower users and builders by making it easier for them to benefit from the web3 ecosystem.

Ankr is working hard to ensure the infrastructure is there for the next cycle to be ***the*** cycle with:

- Extremely fast global connections to blockchains for applications
- Innovative tools to boost the UX of dApps across the board
- Scaling solutions powerful enough for worldwide adoption
- Improvements to node infrastructure for all supported chains

### Growing Our Decentralized Infrastructure Foundation

In the past year, much of the Web3 community was concerned about things such as privacy and decentralization. Events such as the Tornado Cash crackdown and the MetaMask RPC privacy concerns have vindicated our efforts at decentralizing our services as much as possible.

We are focused on delivering services for current and future web3 builders that are aligned with the principles of blockchain and include zero exploitative practices in data or other areas. Our team creates solutions that are true to the decentralized ethos of web3, and will strive to lead the industry in terms of performance and reliability.

With this in mind, we will  innovate with our core RPC platform, ensuring our builders have options to connect to the most chains across Web3. In addition, we will continue to strengthen the high-performance global RPC service which our builders select and from which users benefit. Our hosting platform helps simplify the process of deploying nodes, allowing developers to focus on what matters most - building their application or product. This superior performing system will continue to attract more users to use Ankr, and will strengthen the utility of the Ankr token which is needed to use our network.

### Strengthening ANKR Token Utility

In the [Ankr 2.0 whitepaper](https://www.ankr.com/ankr-whitepaper-2.0.pdf) released in July 2022, we introduced the vision for Ankr Network as a decentralized system where independent node operators work alongside Ankr nodes to power the growth and development of Web3, with a subsidy from the additional services and features provided to developers by Ankr ecosystem contributors and partners. We’ve already implemented two out of three items on our token utility roadmap with one still on the way:

✅ ANKR Token used as payment for infrastructure services.

✅ Enable staking to full nodes for the first time with ANKR Staking.

🛠️ (In progress) Onboard an increased number of independent node providers to serve blockchain requests.

Once all elements of the roadmap are in place, the ANKR token’s utility will be dramatically improved and demand will increase greatly as it is needed for all aspects of the decentralized infrastructure marketplace. And with the next bull run, the token will be one to watch in the rankings. [Learn more](https://www.ankr.com/about-network/token/) about the role ANKR plays for users, providers, and stakers. Stay tuned for our blog post soon for more details on how we’re boosting ANKR token use in 2023.

### Providing More Tools to Build the Next generation of Web3 Apps

In 2022, Ankr built out an entire new vertical of Web3 developer tools and services. Over the next year, we will not only drastically improve these services but add new products and features that make building high-performance dApps easier. Ankr also will continue to provide innovative tools designed to make development easier for creators in the web3 space.

### Building and Growing an Even Stronger Community

Finally, Ankr prides itself on being an open source platform where developers can collaborate together and share ideas freely in order to push boundaries of what’s possible with decentralized technology. We believe that by fostering collaboration across different networks and platforms, we can further accelerate innovation within this burgeoning ecosystem. We do this through our community channels on Discord, Twitter, Telegram, and Reddit. In addition, this year we strive to create online and in person events to help our users connect, learn, and grow.

We will be hosting weekly Fireside Chats on [Twitter](https://twitter.com/ankr) and brand new “Ankr Off Topic” discussions on our [Discord](https://discord.gg/ankr) channel! Stay tuned for our first discussion on the 4th of January with Bomb Money, where we are going to discuss everything about App-Chains and the launch of Bomb Money”

As we continue into 2023, Ankr will remain focused on delivering innovative solutions that benefit both builders and users in a growing Web3 world. We look forward to releasing new features and products over the coming year that will help strengthen our network even further and encourage more innovation.  We believe we can help create an even better decentralized ecosystem than what exists today – one that will allow Web3 innovation to reach its true potential.

2022 was a pivotal year for blockchain and, in many ways, for Ankr. The past months were filled with building, launching, and iterating products that multiplied developers’ power to build successful Web3 experiences. These new experiences, applications, and networks have matured the technology and set the stage for the next market cycle – one that will likely amaze us all with the speed at which new users and institutions alike adopt it. 

As we stand on the verge of a new year, the time has come to reflect on all the events and milestones of 2022 and see how Ankr has innovated to be more than ready for what’s coming next.

## Adding new connections to the blockchain via global RPCs

To further its mission to empower the web3 ecosystem through decentralized innovative technology and tools, Ankr engaged in strategic collaborations with protocols, platforms, and blockchains. 2022 was especially busy for Ankr’s RPC service, adding many new partners and connections for key blockchains. We’re particularly proud of being among the first providers to Sui, Aptos and Optimism and meet the growing need for RPC endpoints serving as a gateway for developers to interface directly with these chains.

In February, we [teamed up with IoTeX](https://medium.com/ankr-network/ankr-teaming-up-with-iotex-to-speed-global-network-growth-fa48947a386) - the leading decentralized network powering the future of Web3, the Internet of Things, and the machine economy (MachineFi) – to build a robust global network of nodes.

March rolled around with another [strategic partnership with Syscoin](https://medium.com/ankr-network/ankr-partnering-with-syscoin-to-expand-global-network-17f38b5336fe), a multi-layered blockchain network. The addition of a high-performance Syscoin RPC incentivized independent and enterprise Syscoin node operators to add their nodes to the Remote Procedure Call in return for ANKR tokens. Launching Syscoin’s RPC removed developers’ need to set up their Syscoin nodes, saving them hours of setup and adding many additional Syscoin nodes to create a more robust network.

In April, we released [Public and Premium RPCs for Harmony](https://medium.com/ankr-network/harmony-rpc-now-live-on-ankr-protocol-987dc0d34955) - a layer-1 blockchain that enhances scalability with sharding and an “Effective Proof of Stake” mechanism to introduce more decentralization and security. Ankr’s Harmony RPC endpoints are a gateway for interfacing directly with Harmony catering to the thousands of new developers looking to work with Harmony.

And that was just the beginning! We followed the first quarter of 2022 with even more integrations, launching RPC connections to in-demand blockchains [Optimism](https://medium.com/ankr-network/meet-optimism-our-newest-rpc-partner-on-ankr-protocol-d0ecd84938ed), [Aptos](https://medium.com/ankr-network/ankr-leading-the-way-with-aptos-rpc-service-44437c114574), [Gnosis](https://medium.com/ankr-network/ankrs-newest-rpc-is-ready-to-serve-gnosis-builders-4886c9e12ef4) and [Klaytn](https://www.ankr.com/blog/ankrs-new-klaytn-blockchain-connection-live/), and becoming one of the first providers of a new [RPC service](https://www.ankr.com/rpc-service/) for the highly anticipated blockchain [Sui](https://www.ankr.com/blog/ankr-offers-the-first-sui-blockchain-connection/). We’re confident Ankr’s strategic move ahead of extending [Sui testnet](https://www.ankr.com/rpc/sui_testnet) to a mainnet connection as soon as it is live (estimated early 2023 will amplify the utility of the “smart contracts platform” and Layer-1 blockchain from Mysten Labs. Our RPC service is also compatible with the [Sui SDK](https://github.com/MystenLabs/sui/tree/main/sdk), enabling more streamlined development.

Optimism marked our 17th RPC partnership to support the developers’ community with a robust RPC layerwith the ability to handle vast traffic loadsthat handle vast traffic loads. The partnership is also an amazing update for dApp developers looking to integrate capabilities for low-cost and lightning-fast dApps. Each new addition to Ankr’s RPC service marked an important milestone in bringing new tech and scalability benefits to Web3 developers so they can build applications with the ability to reach billions of new users with an improved Web3 experience across multiple blockchains and environments.

To provider builders with more ways to develop on web3, we introduced a [new Pay-as-you-go model for Ankr Premium RPC services](https://medium.com/ankr-network/ankr-switching-to-pay-as-you-go-model-for-premium-users-ecfaa6684dd9). Previously, those using Ankr’s Premium Plan all needed to pay the same annual fee. But now, our PAYG plan will allow developers to use our service more flexibly and efficiently – paying for RPC requests as they make them.

Ankr grew by 2,000% in serviced RPC requests in 2022 and is currently at the forefront with more supported blockchains than any other provider with 23+ (and still counting…) Proof-of-Stake chains . With 40,000 distinct developers and 30+ global regions with nodes serving traffic, we’re going strong and setting the standard for [RPC/API connections](https://www.ankr.com/rpc/) to different chains.

## Scaling Web3 Infrastructure through Bare Metal Servers

Web3 infrastructure, L1 and L2 integrations and dApp development have come a long way in just a few years, and 2022 saw Ankr lead the way in  promoting global decentralization. Our [partnership](https://aithority.com/technology/blockchain/ankr-partners-with-bare-metal-cloud-provider-maxihost-to-scale-web3-infrastructure-globally/) with bare metal provider, Maxihost opened new avenues for monetizing existing unused server capacity through Ankr Protocol while supporting a more distributed global node network. This is a step in the right direction for promoting the growth and increasing the adoption of Web3 platforms, applications, and services.

Maxihost’s global platform, in tandem with Ankr’s monthly volume of 250 billion requests across 50 blockchain networks, means we can continue expanding distributed global networks and improve inter-node communication latency to meet the growing demand for nodes.

## Building the Future of Blockchain in Sports

Crypto and sport have long been a winning combination, and pioneers like Chilliz paved the way for a new form of team-fan engagement, interaction, and monetization. [Chilliz’s partnership with Ankr](https://medium.com/chiliz/chiliz-taps-ankr-to-develop-chiliz-chain-2-0-the-blockchain-for-sports-and-entertainment-98c2890f5a7) will lead the development of Chiliz Chain 2.0 (CC2) – a new Layer-1 blockchain- and enable sports and entertainment brands to start building for this new digital paradigm. Having already pioneered the widespread use of blockchain technology by elite sporting organizations, the first Layer-1 blockchain created especially for the sports and entertainment industries will catalyze the broader adoption of blockchain technology across sports and entertainment.

## Global Presence on Offline Events

The Ankr team was busy flying around the world and participating in some of 2022’s most happening summits, blockchain expos, conferences and events. We hosted AMAs, our co-founder Stanley Wu gave an [interview for Nasdaq](https://www.nasdaq.com/articles/how-blockchain-layers-work:-interview-with-ankrs-stanley-wu), our head of product, Josh Neuroth, spo[ke during a mainstage panel discussion and hosted a workshop](https://medium.com/ankr-network/ankrs-ethdenver-2022-itinerary-93c5dabf6889) and our Head of DeFi Filipe Gonçalves [dived deep](https://www.youtube.com/watch?v=IoddFwBTWJs&t=335s) into the mechanics of benefits of liquid staking at the [Staking Summit](https://newsletter.stakingrewards.com/p/the-worlds-first-staking-summit-will?sd=pf). 

![photo_2022-12-28_17-49-52.jpg](/uploads/photo_2022_12_28_17_49_52_e0e1bf342b.jpg)


Between developing new products, adding new nodes to our RPC service and forming new partnerships, we found the time to be a part of the Eth Dever Web3 hackathon, the Avalanche Summit, Binance’s Blockchain Week Paris, Messari New York and throw a kick-ass Ankr Party in Amsterdam for Eth Amsterdam. 

![photo_2022-12-28_17-49-53.jpg](/uploads/photo_2022_12_28_17_49_53_110ddf5a9c.jpg)


## Getting Our Gaming On

2023 saw Ankr hit another milestone regarding expanding our product offering with the launch of a Gaming SDK to accelerate the advent of Web3. Beyond giving game developers everything, they need to create an amazing Web3 game, from best-in-class web-3 infrastructure to NFT’s, marketplaces, and multi-chain wallet integrations. The feedback was so positive that we decided to take this to the next level with a Second Gaming SDK on the popular Unity and Unreal engines to allow developers to integrate games with multiple blockchain ecosystems including Ethereum, BSC, Polygon, Fantom, Avalanche, and more.

We’re thrilled that [Meta Apes](https://metaapesgame.com/) chose Ankr’s Gaming SDK and AppChain-as-a-Service to create a Web3 gaming experience out-of-this-world! The real player-owned Web3 Game runs on BNB Application Sidechain (BAS), which allows it to have its own chain dedicated to Meta Apes only (Ape Chain).

Ankr’s comprehensive gaming SDKs supporting Unity and Unreal Engine provide an easy-to-use, complete solution for adding a wide range of Web3 features that will make games more fun for players in the coming Web3 era.

## Creating a New Environment for Decentralized Development

To meet the growing demand for Web3 projects and dApps scaling solutions, Ankr launched several products to provide developers with maximum flexibility and sovereignty. Our [AppChains](https://medium.com/ankr-network/ankr-app-chains-the-future-of-web3-development-e94ec0bf9c72) are an end-to-end solution for creating app-specific chains on ecosystems to build extremely customizable blockchains with higher performance, usability, and interoperability levels. To further enhance developer experience when operating with the AppChains, Ankr launched [Chainscanner](https://medium.com/ankr-network/introducing-chainscanner-4a96e991b31a), an all-in-one block explorer and crypto analytics platform for app-specific blockchains (AppChains).

One of the high points in the AppChain product offering was the [launch](https://medium.com/ankr-network/ankr-helps-launch-the-future-of-bsc-sidechains-b42926661ad3) of the first **Binance Smart Chain Application Sidechain** **(BAS)** testnet along with [Celer](https://www.celer.network/) and [NodeReal](https://meganode.nodereal.io/). This announcement was a critical moment in the BNB Chain’s 2022 [roadmap](https://www.bnbchain.world/en/blog/bsc-2022-build-and-build/), and Ankr was proud to support the BNB ecosystem as an infrastructure partner. The Binance Smart Chain Application Sidechain (BAS) framework will allow developers to build highly scalable dApps and games on Binance Smart Chain via dedicated sidechains.

Further to our efforts to support developers in integrating Web3 capabilities into their projects, Ankr also released [Advanced APIs](https://medium.com/ankr-network/ankr-launches-specially-designed-advanced-apis-44c423256244). The collection of RPC methods was created to simplify querying blockchain data of all types. With Ankr’s Advanced API service, the blockchain data developers need is easier, quicker, and cheaper to retrieve.

## Becoming a Default Infra Provider on Ethers.js Library

Ethereum remains the golden standard for Dapp development and its Ethers.js library is the complete and compact library for interacting with the Ethereum Blockchain and its ecosystem. [Becoming a default infra provider on Ethers.js library](https://medium.com/ankr-network/ankr-is-a-default-infra-provider-on-ethers-js-library-d3f98645bdb2) is a true testament of trust in Ankr’s capacity to provide a safe, robust and easy way to begin developing on Ethereum, and for use in production.

## Working to Bridge CeFi and DeFi

Crypto is moving toward the mainstream. As part of our efforts to increase adoption  Ankr joined [Start Path Crypto](https://developer.mastercard.com/programs/start-path-crypto/), Mastercard’s blockchain-focused startup engagement program and other companies and startups. We view this move as the next logical step in acquiring the partnership opportunities, insights and tools we need to grow and position crypto from largely speculative investment to a global financial phenomenon.

## Ushering In a New Age in Liquid Staking

2022 was the year when liquid staking became a dominant trend in DeFi, gaining traction with 11 billion $+ deployed through liquid staking protocols. Throughout the year, Ankr was at the forefront of liquid staking developments, developing and supporting liquid staking products on seven different L1s and continuing to expand.

As part of our Liquid Staking tokens model overhaul, we simplified users’ staking experience - removing reward-earning tokens (b-tokens) and standardizing the names of reward-bearing tokens (c-tokens).

Staying true to our ethos of growing and preserving wealth in a decentralized manner, we launched a Referral program that lets anyone [become an Ankr partner](https://www.ankr.com/docs/staking/for-integrators/referral-program/overview/) and generate more revenue attracting new users to Ankr Liquid Staking.

Although we experienced an exploit on the aBNB token due to a social engineering attack this year, we learned a lot from this incident, were able to act fast and contain losses. As unfortunate as this exploit was, we executed a [Recovery Plan](https://www.ankr.com/blog/after-action-report-our-findings-from-abnbc-token-exploit/) and are proud of how the team handled the situation at every turn and did right by taking care of our community.

We’re ending the year on a high note as a top 1 liquid staking provider with [$144.9m in TVL](https://dune.com/ankr/bnb-liquid-staking-monitor) (Total Value Locked) and an Average APY of 4.35%.

## Increasing exposure for the $ANKR token

$ANKR is the glue that holds the whole Ankr ecosystem together, and we’re thrilled to see its **acceptance is on the upswing as the token got listed on Kraken,** one of the most popular cryptocurrency **exchanges** used by many on a global level. The [listing on Kraken](https://mobile.twitter.com/krakenfx/status/1483514633235443715) represents yet another top-tier exchange listing with $ANKR already listed on some of the biggest exchanges on the market – Binance, Coinmarketcap, Bithumb, Bittrex, and Kucoin, to name a few.

In 2022, the $ANKR token was in the spotlight for all the right reasons, including a new [staking mechanism](https://www.ankr.com/docs/app-chains/components/staking-ui/) to amplify rewards and returns for our community and users. The launch of Ankr Network 2.0 saw us introduce staking to independently run full nodes, allowing users to stake their tokens with the independent full nodes running on our new decentralized Network.

These are just a few of the ways we sought to enhance our ability to offer our clients and users the finest services by working side by side with crypto projects, DeFi protocols, blockchains and DEXs. And as 2022 brought about significant challenges to overcome, we are confident we remain on the right track humbled and empowered by the continuous support of our community and partners. We can’t think of a greater testament to the trust we’ve been given than [Binance Labs’ strategic investment in Ankr](https://www.binance.com/en/blog/ecosystem/binance-labs-makes-a-strategic-investment-in-ankr-8803429302834521105) and our rapidly growing global community.

Thank you for a fulfilling 2022, and we look forward to building with you in 2023!

Ankr 2022 : A Year In Highlights

# We are excited to announce the official launch of a new ankrBNB-BNB Crypto pool on Ellipsis.

![ellipsis2.jpg](/uploads/ellipsis2_606d1e807f.jpg)

We will be offering incentives for users who provide liquidity to the new Crypto Pool by offering bribes to locked DDD holders on DotDot Finance to direct additional EPX emissions to the ankrBNB-BNB pool on Ellipsis. This will further boost the incentives of providing liquidity to this pool.

### The new Liquid Staking Token: ankrBNB

Ankr made the decision to replace aBNBb and aBNBc with ankrBNB in response to the exploit that affected both tokens. With this, the ankrBNB token becomes the main reward-bearing liquid staking token of the BNB Chain.

All liquidity providers who held aBNBb, aBNBc and BNB in Liquidity Pools received an airdrop of ankrBNB and BNB and were fully compensated (the Ellipsis aBNBb–BNB pool is one example of this). The aBNBb and aBNBc token holders were airdroped the respective amount in ankrBNB and were also fully compensated.

This decision allowed Ankr to safeguard the interests of its users and ensure that they were not negatively impacted by the exploit.

It is also important to note that the exploit in question was not a technical vulnerability in the smart contract code, but rather a social engineering attack. To learn more about this exploit, you can read the Ankr Token Exploit Report at the following link: [https://www.ankr.com/blog/after-action-report-our-findings-from-abnbc-token-exploit/](https://www.ankr.com/blog/after-action-report-our-findings-from-abnbc-token-exploit/).

### Why a new Ellipsis Crypto Pool?

As you may know, ankrBNB is the BNB reward-bearing token of Ankr where the redemption ratio increases daily based on BNB staking rewards. At the time of this writing, the current redemption ratio is 1 ankrBNB = 1.0404 BNB. This means that ankrBNB is pegged to the BNB price, but its value depends on the current redemption ratio.

Stableswap pools are specifically designed to maintain a stable peg between the tokens in the pool, typically 1:1. This means that the value of one token in the pool should always be equal to the value of the other token, allowing the pool to act as a stable exchange between the two tokens in a more efficient way. The stableswap pools were better suited for the aBNBb as its was rebase token that had a redemption ratio of 1 aBNBb = 1 BNB.

However, this is not suited for ankrBNB because the redemption ratio for ankrBNB is not fixed as it grows daily based on the BNB Chain Staking Rewards and therefore, the value of the token may not stay pegged at 1:1. In this case, it may be more appropriate to use a different type of liquidity pool that is better suited for handling tokens with variable redemption ratios.

An Ellipsis Crypto Pool is the best solution for ankBNB  because it maximizes liquidity by focusing on current prices, concentrating the liquidity, and leading to better exchange rates. When trades occur, the Crypto Pool adjusts its internal price to the area with the most liquidity without experiencing any losses, resulting in an increased capital efficiency.

The Ellipsis Crypto Pool can be accessed at [https://ellipsis.finance/pool/0x440bA409d402e25b95aC852E386445aF12E802a0](https://ellipsis.finance/pool/0x440bA409d402e25b95aC852E386445aF12E802a0).

Ankr Team 

![All_ankr_products_50.jpg](/uploads/All_ankr_products_50_594f8d2974.jpg)

Ankr has become one of Web3’s leading infrastructure providers as our products **amplify the building power of all blockchain developers** that use us. However, we offer such a broad range of products that you may be confused as to where to start and which tools will help you most! Let this article be your guide to give you the full overview of everything that Ankr offers so you can implement the solutions that work best for your project. We’ll look at a range of tools and services for Web3 developers, including RPCs, APIs, and AppChains for developers.

## Ankr’s Product Suite for Developers

Ankr has an entire product vertical that’s designed to facilitate Web3 development. It connects builders to the blockchains they’re building on, gives them data faster, and provides tools to make dApps with a UX better than anything we’ve seen in Web3 thus far. Most of these products and services are offered as part of the Ankr Network, which we’ll dive into below.

## Ankr Network (The Global Nodes Behind All Services)

Before we dive into our different products for Web3 developers, you may be interested to learn a little more about Ankr Network. This is the name we’ve given our full (RPC) node infrastructure that we operate on dozens of blockchains with nodes serving request traffic around the world. Simply put, Ankr Network is the infrastructure that allows us to connect Web3 developers to nodes so that they can communicate with various blockchains and build the future of Web3.

Ankr Network is a network of full nodes (or RPC nodes) that is both globally distributed and increasingly decentralized. These nodes serve data requests from developers as they build blockchain-based Web3 sites and applications. And, with the latest iteration of Ankr Network, this network is becoming increasingly decentralized day after day. Independent node operators all over the world can provide their nodes to Ankr Network, serve shared network traffic (i.e., requests from developers), and earn ANKR token rewards for doing so.

Ankr Network is already being adopted worldwide because of the reliable, fast, and affordable connections it offers to Web3 developers. Today, Ankr Network routinely handles over 7.2 billion RPC calls to the blockchain per day across endpoints that are geo-distributed all across the world and benefit from efficient load balancing. In the coming year, we expect that volume to expand even further.

**[Learn more about Ankr Network](https://www.ankr.com/about-network/)**

## Public RPCs: Fast & Free Connections To Dozens of Chains

Public RPCs serve the critical purpose of powering Web3 applications like MetaMask and other free open-source software by connecting them with information on different blockchains. With easy access to free RPC endpoints, developers and projects can interact with blockchain data and execute tasks like crypto wallet transactions. It also allows developers to build dApps freely on their own terms.

Ankr currently operates [dozens of free, public RPCs](https://www.ankr.com/rpc/) to the most popular blockchain networks for Web3 development. But keep in mind that as a free service, Ankr’s public RPCs have a soft limit of 1M requests per day, and may experience rate limiting during times of heavy network traffic. Builders getting some traction on their dApps will be happy to switch to our Premium services while only paying for what they need with no extra charges.

**[Copy & paste endpoints now](https://www.ankr.com/rpc/)**

## Premium RPCs: Power dApps With Best-In-Class Performance

The Premium plan provides affordable [high-performance](https://www.ankr.com/blog/ankr-leads-the-pack-in-rpc-api-services/) blockchain connectivity for Ankr Network users looking to scale. Pay for RPC requests as you make them and never overpay for monthly subscriptions while gaining access to:

- Dedicated endpoints
- 1,500 requests per second
- WebSockets connectivity
- Advanced APIs

Of special note, Ankr’s Advanced API service is a collection of specialized RPC methods that were created to simplify querying blockchain data of all types. In 2022 Ankr released three powerful APIs: NFT API, Token API, and Query API that are designed to:

- Reduce the number of requests you need to make

## Ankr AppChains: Build Your Own Blockchain Easily

AppChains are known by many names like application-specific blockchains, subnets, supernets, etc., but at their core, they represent an innovative new scaling solution wherein a single Web3 application runs on its own individual blockchain to enable:

- **Enhanced Scalability:** AppChains are dedicated blockchains that serve only one application: yours. Scale your traffic to accommodate nearly any number of users.
- **Customizable Features:** AppChains are highly customizable for tailored programming languages, consensus mechanisms, development frameworks, and security features to suit any industry or use case.
- **Superior User Experience:** Benefits like low (or zero) gas fees and fast transaction speeds ensure your users will be happy using your application.
- **Streamlined Building & Launch Plan:** Ankr AppChains is an end-to-end engineering solution for creating your dedicated blockchain with every building block taken care of. Our Exchange Readiness Program helps projects get their tokens listed on major exchanges and get out in the world faster.
- **Recurring Revenue Stream:** Become a network owner, not a renter. Collect a cut of global gas fees from the validation process and create a revenue stream to power your project.

Currently, dApps are often plagued by high gas fees, congested networks, complex transactions, hacks, and a number of other tech-related problems standing in the way of mass adoption. Many of these problems can be alleviated by dedicating one specific L1 chain to each app. But, of course, the main challenges to doing so are the high technical and monetary costs.

So instead of launching an application on an existing Layer 1 to compete with thousands of other apps for traffic, or building a new Layer 1 from scratch, developers can simply launch their own custom, dedicated AppChain on networks like BSC, Polygon, or Avalanche. These AppChains act like child-chains that are attached to a mainchain, aka parent-chain. With this configuration, the AppChain is able to configure its own consensus mechanism, process its own transactions, and still inherit much of the security and provenance provided by its parent-chain.

With Ankr’s new AppChain as a Service, any Web3 developer can create a new subnet easily, complete with all of the infrastructure needs taken care of. Builders can add their custom specs for consensus, security, programming, languages and much more while receiving fast onboarding and liquidity for their new tokens on major exchanges — all ensuring that their project is successful in as little time as possible.

Ankr strongly believes that app chains will become the forefront of Web3 scaling solutions far into the future, and is dedicated to developing another product offering focused on this new technology: App Chain as a Service.

A Guide To Ankr Products for Every Web3 Developer

![decentralize.jpg](/uploads/decentralize_c50c73764e.jpg)

**TL;DR**

Web3 developers have three choices when it comes to accessing the node infrastructure (blockchain connections) necessary for building and operating dApps. They can run their own nodes, pay for centralized providers like Infura, Alchemy, and AWS, *or* they can use a Web3-native infrastructure provider like Ankr. Ultimately, Web3-native infrastructure is often the best option for the following reasons:

- Running your own nodes is labor, time, and capital intensive with an additional set of technical skills needed.
- Centralized infrastructure is antithetical to Web3 and provides vulnerabilities for censorship, failure, and manipulation.
- **Decentralized infrastructure providers like Ankr offer a solution aligned with the original intent of blockchain tech.** **Developers reach a vast, increasingly decentralized network of nodes with lower latency, more reliability, and high-performance standards while incentivizing node operators, users, and communities.**

## Introduction

Blockchain developers can build new Web3 apps faster than ever, thanks to the growing availability of infrastructure that allows them to communicate with blockchains without needing to set up their own nodes. This is known as the [RPC](https://www.ankr.com/blog/what-do-infrastructure-providers-do-we-connect-the-world-to-web3/) (Remote Procedure Call) layer, which could be classified as a type of API (Application Programming Interface) that interacts with a network of nodes. These tools are vital for developers in building the dApps and open-source software that power Web3 experiences.

Setting up your own node infra can be very complicated and expensive. That’s why blockchain developers and projects seek RPC providers like Ankr to grant them hands-free access to interface with blockchains. These services allow them to make request calls to blockchains and read and write data to blockchains via the RPC extremely easily. In short, the RPC providers take the technical infra requirements out of the picture so developers can focus on creating dApps.

## Why Use Web3-Native Infrastructure for Connecting To Blockchains?

There are two options for RPC providers – centralized companies providing a purely transactional subscription-based service, or Web3-native providers such as Pokt or Ankr that have a little more stake in the game (literally). **The difference lies largely in dedication to the Web3 community.** Ankr provides:

- Open-source tools
- Public goods
- Engineering support
- In-depth partnerships with foundations

Put simply, Ankr offers solutions that are created by web3 developers, for web3 developers because we are committed to growing the industry as a whole according to its most important principle – decentralization.

### The Tech Is Customized for Blockchain

Most Web3 infrastructure providers use AWS data centers exclusively to house their nodes. Web2 cloud and database technology often falls short when attempting to deliver quality blockchain RPC/API services. The requirements of decentralized systems are much better served by infrastructure that has been customized and built specifically to serve unique demands. Using AWS also limits the global distribution of nodes and leads to higher latencies.

On the other hand, Ankr has spent years building our server/node infrastructure from the ground up, customizing it specifically for the demands of Web3 for [better performance](https://www.ankr.com/blog/ankr-leads-the-pack-in-rpc-api-services/):

**Other providers**

- Provide a cloud-based service using AWS
- Constrained to AWS data center locations
- Complexities of Web3 tech bog down servers with traditional data validity requirements

**Ankr**

- Serves requests from a high-performance blend of bare-metal and cloud servers globally
- In more global data centers in more locations than any provider
- Runs nodes on custom servers optimized for blockchain & our tailor-made software

### Avoid a Web2 Model for Web3 Systems

The internet, as we’ve known it for some time, relies largely on massive service providers to offer the computing infrastructure to run the web and cloud-based operations housed in huge data centers. In order for the internet to work, we need to pay these goliaths their dues. But do we want Web3 to operate the same way?

We all want Web3 to be as accessible as possible, so we want fewer paywalls and barriers to entry when it comes to interfacing with node infrastructure. Centralized providers don’t price their services for the communities — they do it to secure as much profit as they can. Alternatively, with Ankr's pay-as-you-go plans, builders only pay for what they use with affordable developer-first pricing. 

### Enhance Privacy & Autonomy

Purely centralized providers have more risk of directly or indirectly barring users from dApps that use their infrastructure based on location, government sanctions, or other factors, as we’ve seen in the past year. Having Ankr as a more decentralized provider means less exposure to these risks while collecting less information about your usage history. Use our [RPC endpoints](https://www.ankr.com/rpc/) to give your wallet or dApp a connection to blockchains that is more private and secure:

- Ankr stores no PII or have a method to correlate wallet transactions to IP addresses
- Ankr never uses our RPC to front-run transactions (MEV exploitation on your transactions)
- We continue to decentralize the RPC as much as possible while preserving quality service

Use our endpoints to customize your MetaMask RPC: **[See step-by-step instructions](https://twitter.com/ankr/status/1597561171216777219)**

### Eliminate Single Points of Failure

Consider the following potential situation with a mainly centralized platform that relies on centralized infrastructure to interface with blockchains.

**The Ripple Effect**

- AWS experiences a widespread outage.
- A centralized provider with AWS-based nodes goes down.
- OpenSea's services are now disrupted or unavailable as they rely on the provider.
- Twitter's NFT functionality is unavailable since it relies on OpenSea's NFT API.
- NFTs are difficult to verify, resulting in a breakdown in the UX and usability of non-fungible assets.

Alternatively, what if OpenSea's platform relied on a more decentralized infrastructure? The above scenario would have a much more favorable outcome: one cluster of independent nodes goes down, Ankr's load balancer immediately transfers the traffic to other unaffected nodes in other regions, OpenSea's NFT services remain operational, and Twitter's NFT functionality remains fully functioning.

## Final Thoughts

We have an opportunity to build a new layer of the web that provides autonomy, privacy, censorship-resistance, and self-governance without a need for companies over-capitalizing on its use. Decentralized infrastructure is the missing puzzle piece that allows us to build, transact, communicate, and earn rewards on the future web independently and scalably.

Ankr’s Public RPCs: Instant Connections to Dozens of Chains

## An odyssey of data and frustration of a developer

Ah, the joys of querying Web3. It's like going on a grand adventure, where you're not quite sure what you're looking for or where you're going to find it. You might start out with a simple query, something like "How many transactions were processed on the Ethereum network yesterday?" But before you know it, you're down the rabbit hole of complex data structures, arcane technical jargon, and seemingly endless frustration.

The first challenge you'll face is figuring out how to actually query the data you're looking for. Once you've finally figured out which method to use, you'll need to start dealing with all of the technical details. You'll need to figure out which Ethereum node to connect to, what the correct block number or transaction hash is, and how to format your query in a way that the node will understand. 

And even then, there's no guarantee that you'll get the data you're looking for. The Ethereum network is notoriously unreliable, and you might find yourself getting error messages or incomplete results.

But even if you manage to get your query working, you're not out of the woods yet. Just because you have the data doesn’t mean it’s usable yet. It's like trying to solve a puzzle with only half the pieces.

## The challenges of Web3 data querying

Web3 data querying is a hot topic among developers, with many of them struggling to find the best way to access the vast amounts of data on the decentralized web. This has led to a rise in the use of APIs, which provide a simple and effective way for developers to query data on the blockchain.

One of the biggest challenges faced by developers when it comes to querying is the sheer amount of data that is available. With millions of transactions and blocks being added to the blockchain every day, it can be difficult for developers to know where to start when it comes to accessing this data.

Another challenge is the complexity of the data structures. Unlike traditional databases, which are organized in a simple, hierarchical manner, adding cross-chain functionality can be a complex task, as data does not flow easily between different blockchain networks. This added layer of complexity can make it more challenging to integrate and utilize multiple blockchains in a single system

## The state of API development

In response to these challenges, many developers have turned to APIs, or application programming interfaces, to help them access data on the decentralized web. APIs provide a way for different software systems to communicate with each other and share data and functionality, making it easier for developers to build complex interconnected applications.

There are several different types of APIs available, each designed to serve a specific purpose. Some APIs allow developers to query data directly from the blockchain, while others provide access to third-party data sources, such as exchanges or other decentralized applications.

## The Data Layer for Web3 dapps

Web3 dapps are applications built on top of the blockchain and use smart contracts and other decentralized technologies to provide a wide range of services and functionality.

However, building and running a Web3 dapp is not as simple as building a traditional web application. Unlike traditional web apps, which can easily access data from centralized databases, Web3 dapps must rely on the blockchain for their data needs. 

That's where APIs come in. APIs provide a simple and standardized way for Web3 dapps to access data on the blockchain, allowing developers to query data and interact with smart contracts in a consistent and predictable way. In this sense, APIs can be thought of as the data layer for Web3 dapps, providing a common interface that can be used by any dapp, regardless of its specific requirements or underlying technology. 

## Build with Ankr Advanced APIs

Ankr offers advanced APIs that make it easy for developers to build and ship powerful dapps. These APIs provide a wide range of tools and features, including support for NFTs, tokens, and data querying. This allows developers to build complex and feature-rich dapps, without the toiling of setting up complex RPC calls, that provide value to users and take advantage of the full potential of the web3 data.

### NFT API

One of the most popular Ankr APIs is the NFT API, which allows developers to access and query data related to non-fungible tokens, or NFTs. NFTs are unique digital assets, such as artwork or collectibles, that are built on top of the blockchain. They are often used in Web3 dapps to represent virtual items or assets and can be traded and exchanged on decentralized exchanges.

![Untitled.png](/uploads/Untitled_c5de8a2d9b.png)

The NFT API offered by Ankr provides developers with a simple and standardized way to access and query data related to NFTs. With the NFT API, developers can easily retrieve information about specific NFTs, such as their metadata, ownership, and transaction history. They can also use the API to display and manage NFTs within their NFT galleries, wallets and marketplace dapps, providing their users with a seamless and secure way to interact with these unique digital assets.

### Token API

Another important API offered by Ankr is the Token API, which provides developers with access to data related to tokens. Tokens are digital assets that can be traded and exchanged on the blockchain and are often used to represent a variety of different assets, such as cryptocurrencies, utility tokens, and stablecoins. The Token API allows developers to query data related to tokens, such as their token holders, prices, and account balances.

### Query API

With the Query API, developers can easily retrieve information about transactions, blocks,  and logs, making it easier to build applications that rely on this data. Additionally, Query API offers developers a simple and standardized way to access data from multiple blockchains, without having to worry about the complexities and differences of each individual chain.

Web3 Data Challenges and the State of APIs

![Medium Post_14.12.jpg](/uploads/Medium_Post_14_12_b13b29c0d1.jpg)

After restoring security and responding to the events of the Dec. 1st exploit of our aBNBc token, Ankr has carefully reviewed the facts and taken steps to prevent any attacks like it in the future. Regardless of any damage done, we are proud of how the team handled the situation at every turn and did right by taking care of our community.

**After the hack Ankr immediately:**

- Restored security and worked with DEXs to halt trading
- Formed and executed a thorough recovery plan for the community
- Identified the exploiter (currently working with law enforcement to take appropriate legal action)

## Who Caused The Exploit?

A former team member (who is no longer with Ankr) acted maliciously to conduct a combination of a social engineering and supply chain attack, inserting a malicious code package that was able to compromise our private key once a legitimate update was made. We are in the process of working with law enforcement to prosecute the former team member and bring them to justice. Unfortunately, internal bad actors can affect any protocol and we are working on shoring up internal HR processes and safety measures to strengthen our security posture going forward.

## How Did We Respond?

### Immediate Action Taken To Halt the Attack

Right away, Ankr took several actions to minimize any damage from the exploit:

- Communicated the exploit to the public and executed plans to resolve the situation as quickly as possible.
- Alerted known off-ramps to implement their emergency plans and halt trading
- Secured the smart contracts with a new key, preventing any further tampering.
- Updated smart contracts and systems to temporarily pause the movement of the underlying collateral (BNB) within our liquid staking product to be safe.

### Formed a Recovery Plan

Ankr took several measures to start compensating users to the full extent of the losses they incurred as a result of the exploit. **The team used our own Advanced API Tool to find every aBNBc token holder in 10 seconds – a task that would have taken several hours to complete using normal query methods on a dedicated node.**

- Took a snapshot to identify affected users
- Created a new ankrBNB token
- Airdropped the token to affected holders
- Determined reimbursement plan for most impacted users

### Reimbursed Our Community

Ankr is a Web3-native organization with an extremely strong community. To uphold this reputation, we needed to do the right thing and reimburse all token holders who were affected.

- Fixed damage to Helio (aBNBc borrowing platform) by re-stabilizing HAY Price. We will continue purchasing HAY if the token remains unpegged until all funds are spent.
- Airdropped ankrBNB to the affected aBNBc or aBNBb token holders
- Airdropped BNB to all affected DeFi liquidity providers
- Reached an agreement to reimburse Wombat stkBNB LPs and planned to provide 100% coverage of the BNB Wombat LPs.

**See [more details](https://www.ankr.com/blog/ankr-makes-progress-with-recovery-program-targets-and-milestones/) on our recovery plan.**

## What Are We Improving?

Ankr is now implementing several improvements to our security posture. Here are a few notable reinforcements:

**Requiring Multi-sig Authentication & Timelocks for All Updates**

The exploit was possible partly because there was a single point of failure in our developer key. We will now implement multi-sig authentication for updates that will require signoff from all key custodians during time-restricted intervals, making a future attack of this type extremely difficult if not impossible. These features will improve security for the new ankrBNB contract and all Ankr tokens.

**Revamping internal security measures**

Ankr will now require escalated background checks for all employees (including all contractors and remote workers) while taking extra measures to verify the current status of those currently working at Ankr. We are also reviewing access rights and taking extra steps to minimize entry to any sensitive systems.

**Implementing new monitoring & notification systems**

The team was able to catch the attack extremely quickly, but we can always work on improving our response time. We are implementing new notifications systems to alert key personnel so they can be online faster during any time of day.

**Refining procedures for working with DeFi protocols**

Now that we’ve been through the experience of working with teams from other protocols after an incident, we can improve the process with precedent set for responding with international teams in streamlined communication channels.

## More Updates To Come

**We want to thank the community for your ongoing support during this time!**

We are still working on ensuring all loose ends are tied up and all affected users we identified have been reimbursed. Our goal is to resolve every inquiry that has stemmed from the exploit and this will take time. Thank you for your patience and understanding.

After Action Report: Our Findings From the aBNBc Token Exploit

![airdrop.jpg](/uploads/airdrop_c24c5f6aad.jpg)

It’s been a week since Ankr detected a hack that resulted in excessive minting of our BNB liquid staking token (aBNBc) and its rapid exchange for other tokens on decentralized exchanges. The team was able to briskly patch the exploit within hours and deploy an initial $15m Recovery Fund that has now been exceeded to compensate DeFi BNB liquidity providers, BNB lenders, and DeFi protocol users affected by the aBNBc exploit.

The compensation plan is scheduled to take part across several stages so we can monitor conversions and move quickly to reimburse all legitimate and affected aBNBc & aBNBb token holders based on a snapshot taken December 2, 2022 (Dec-02-2022 at 12:43:18 AM +UTC - Block number: 23545403).

## What Has Been Accomplished So Far?

After announcing the Recovery Strategy on the [Ankr blog](https://www.ankr.com/blog/the-abnbc-token-report/) and our official [social media channels](https://twitter.com/ankr/status/1598768146088742912), we took several measures to start compensating users to the full extent of the losses they incurred as a result of the exploit.

So far, we have been able to complete various Airdrops of ankrBNB and BNB tokens to wallet addresses that held aBNBc and aBNBb at the time of the *snapshot* through smart contracts and liquidity pools. The team is working closely with several DeFi protocols to ensure the safety and best interest of their communities. We will continue to share further updates as they are released.

As of now, we have met the following milestones in our Recovery Plan:

### Re-stabilized HAY Price

On Thursday, December 8th, 2022, Ankr finalized the purchase of 6,843,323 HAY on Decentralized Exchanges out of the entire 17,747,582 HAY of accumulated bad debt. This move succeeded in stabilizing HAY’s price, pushing HAY/BUSD up to $0.98. 

Additionally, on Tuesday, December 13th, Ankr burned **6,000,000 HAY,** which is the first burn to the [Helio Bad Debt Burn Address](https://bscscan.com/address/0x192D4e2E19A01e49b30Fb3894A01B6e08947d9CA). Immediately after the incident, the Helio team stated that it would be repurchasing the excess HAY and sending it to a burn address. Helio Protocol had a total value locked of approximately $90 million before the incident of which Helio has already bought back $3 million worth of bad debt in HAY in the open market.

### Airdropped ankrBNB to Affected DeFi Users

On Friday, December 9th, 2022, Ankr airdropped ankrBNB to wallet addresses that held aBNBc and aBNBb at the time of snapshot through smart contracts for a number of partner DeFi protocols. We were able to complete the airdrop for the following protocols:

- Ellipsis Finance
- PancakeSwap
- Beefy Finance
- ApeSwap
- ACryptoS
- Wombat
- Wombex
- Magpie
- Quoll

### Airdropped BNB to Affected LPs

On Monday, December 12th, 2022, Ankr airdropped BNB to wallet address that held BNB through aBNBc or aBNBb liquidity pools. The liquidity pools we compensated addresses for are:

- ACryptoS ASCI Farm: 18.57922911707609861 BNB
- ACryptoS LP: 0.312655746961921 BNB
- ApeSwap LP: 192.73227886323606338 BNB
- Ellipsis LP Beefy Vault: 829.820502618376604417 BNB
- Ellipsis LP DotDot Farm: 332.017235831474294796 BNB
- Ellipsis LP Farm: 17.327942433773631424 BNB
- Ellipsis LP: 9.987203105242974679 BNB
- Kalmy vault: 52.996829992 BNB
- Izumi LP: 509.783825632276009070 BNB
- PancakeSwap LP Beefy Vault: 697.936888689457446913 BNB
- PancakeSwap Farm: 6,225.408642285559266733 BNB

### Airdropped ankrBNB to Missing Addresses

Ankr also airdropped ankrBNB to missing wallet addresses that held aBNBc and aBNBb at the time of the *snapshot* through smart contracts on the following protocols:

- Izumi
- DotDot Finance
- Kalmy

### Unlocked ankrBNB  Transfers

After halting trading for aBNBc and aBNBb tokens and completing the token migration to the new ankrBNB, we are unblocking transferability of newly airdropped ankrBNB tokens.

### Plan for Reimbursing Wombat stkBNB LPs

As of December, 19th, we have reached a bilateral agreement with pStake to airdrop 2,654.352 ankrBNB and 681.051 stkBNB, which will partially cover the loss of stkBNB liquidity providers on Wombat. The nature of the mixed liquidity pools on the decentralized exchange poses a challenge in estimating the losses of affected users but Ankr is happy to have reached a decision with the management team of Wombat for adequate compensation. 

### 100% coverage for Wombat BNB LPs

Ankr will provide 100% coverage of the BNB Wombat LP estimated at **14,407.155 BNB. At the first stage of the Recovery Plan for Wombat users, wallets that directly or indirectly held Wombat BNB LP tokens at the time of the snapshot will be compensated in full on December, 19th. 

Later this week, we will compensate wallets that directly or indirectly held Wombat BNBx LP via an airdrop for 50% of the tokens they held. 

### What is Ankr's Rationale Behind the Recovery Plan and Airdrops? 

Over the last couple of weeks, Ankr has held multiple talks with partners and professionals in the crypto field, consulting with key stakeholders impacted by the aBNBc exploit in the @BNBChain ecosystem. Our strategy was designed with all affected parties and our community's best interest in mind to ensure fair and timely compensation.

To this effect, we made a decision to accelerate the ankrBNB token mint to provide complete protection to Ankr liquid stakers. Ankr covered 100% of all the DEX LPs that we have incentivized on at least one occasion. 

The BNB LP Wombat was co-incentivized by Ankr alongside pStake and Stader. Our calculations show that about 24% of that pool held Ankr liquid staking tokens funded via our liquid staking proportion on the Wombat common LP. Nevetheless, Ankr has made the decision to cover 100% of the pool to mitigate the adverse effects on liquid staking liquidity pools in general as a result of the exploit. We see having BNB suppliers as essential for BNB liquid staking and want to continue playing a key role in the advancement of liquid staking as a new standard in DeFi as whole. 

Despite the stkBNB LP and BNBx LPs never having been incentivized by Ankr, we acknowledge the aBNBc exploit affected both stkBNB and BNBx. However, these are inherent risks that multiple token pools bear due to their design. Ankr never incentivized any stkBNB or BNBx token holders to enter this pool but we will cover 50% of those pools with an airdrop as a sign of our goodwill. After careful consideration, we believe this strategy to be fair given the circumstances of the exploit and the fact that Ankr has never provided any incentives to enter stkBNB LP and BNBx LPs.


## In Conclusion  

**We want to thank the community for your ongoing support, patience, and feedback during this time.**

Please see our [After Action Report](https://www.ankr.com/blog/after-action-report-our-findings-from-abnbc-token-exploit/) for more details on our findings from the exploit.

Ankr Makes Progress With Recovery Program Targets and Milestones

![shrunk more locations.jpg](/uploads/shrunk_more_locations_6217c48b78.jpg)

Web3 is a truly global movement that serves every country and corner of the world. The crypto industry never sleeps – and the 24/7 markets and protocols serving DeFi, NFTs, Web3 gaming, and other applications require constantly available node resources to reach blockchain data. Such a resource-intensive industry needs providers that can deliver incredibly fast and reliable blockchain connections closer to wherever its users happen to be. This has become Ankr’s strong suit.

With enterprise-grade nodes operated by Ankr from independent data centers worldwide, **Ankr gives Web3’s global user base a more reliable, low-latency, and efficient experience no matter their location.** With a globally distributed network, there are always nodes nearby, resulting in reduced latency for all kinds of applications.

This is one of the reasons why Ankr is the fastest-growing Web3 Infrastructure provider serving nearly 8 billion RPC requests daily on the [23+ blockchains supported](https://www.ankr.com/protocol/public/) by Ankr.

## Ankr Powers Web3 Worldwide With Nodes in 30 Regions

Just like cell networks or cloud service providers need equipment and servers close to their customers for fast and reliable service, Web3 infra providers need nodes running globally to provide the highest quality service to developers, dApps, and ultimately end users.

![Screenshot 2022-12-16 130111.png](/uploads/Screenshot_2022_12_16_130111_ef56847c71.png)

*Ankr is constantly expanding our infrastructure which serves as a public good and critical service to so many foundations and projects.*

If a cell provider only had infrastructure in North America but had customers all over the world, that would be a problem. The same principle applies to Web3. However, many of the largest Web3 infrastructure providers have limited service locations.

Most centralized providers only have nodes in one region. Some of the top names in Web3 infrastructure have their servers placed only in the eastern United States, constrained to the AWS data centers in that region. While they still serve traffic coming from around the world with high-quality connections, their performance could be greatly improved by expanding the network globally.

Alternatively, Ankr has nodes serving billions of RPC requests from around the world every day from the most distributed infrastructure of any provider.

![30_Regions_50.jpg](/uploads/30_Regions_50_883cde6b49.jpg)

## Independent Node Providers Spreading the Traffic Load & the Map

Not only are there Ankr-run nodes operating in more regions than any other provider, but we are also adding to a growing list of independent node providers and partners who add even greater location diversity. Among those putting up nodes to serve traffic coming to Ankr Protocol are:

- Pocket Network
- Harmony
- IoTeX
- Chainstack
- Fantom
- Debooks
- QuickNode
- And more!

## Where Are Ankr’s Nodes Located?

![map2.png](/uploads/map2_7a8fa23123.png)

*This map shows 24h of global user requests. Ankr places nodes strategically in all of these regions to ensure extremely fast speeds for all users.*

Unlike less distributed providers, Ankr’s nodes are spread across independent data centers worldwide. Ankr has been installing bare metal servers for years in 30 of the various cloud regions in North America, South America, Europe, the Middle East, Asia, Oceania, and Africa.

To serve users best, Ankr pays close attention to where high volumes of requests are coming from and quickly supplements the region with nearby nodes. These nodes are most often housed in colocation data centers (aka Colos) that offer high levels of security and reliability. Ankr also has a great [partnership with Maxihost](https://www.globenewswire.com/news-release/2022/01/26/2373635/0/en/Ankr-Partners-with-Bare-Metal-Cloud-Provider-Maxihost-to-Scale-Web3-Infrastructure-Globally.html) which helped us install over a hundred bare metal servers just in Latin America.

“*We’ve been very intentional about our node locations and data center partnerships. We’ve spent years building our infrastructure from the ground up and deploying nodes in close proximity to all DeFi and Web3 users to provide a low-latency experience. Onboarding more independent node providers to Ankr Network will make it even easier to make sure we can cover every part of the world.*”

– Josh Neuroth, Ankr’s Head of Product

Ankr Supports More Regions Than Any Web3 Infrastructure Provider

![Medium Post_14.12_2.jpg](/uploads/Medium_Post_14_12_2_9756d9c617.jpg)

Since 2017, Ankr has been helping blockchain developers create dApps by providing the highest quality [RPC/API connections](https://www.ankr.com/rpc/) to different chains. Exceptional dApps need high-performance infrastructure – that’s why Ankr has become the go-to provider for projects requiring a higher bar of service.

Ankr powers dApps while excelling in every metric that matters when connecting to blockchains:

- Speed
- Reliability
- Affordability
- Supported Blockchains
- Global Distribution
- User Experience
- Decentralization

## Why Does RPC Performance Matter?

[RPC](https://www.ankr.com/blog/what-do-infrastructure-providers-do-we-connect-the-world-to-web3/) connections are the messengers or “blockchain routers” that relay on-chain information between nodes, dApps, and ultimately end-users. This allows users to execute necessary tasks like sending transactions, populating wallet balances, fetching ownership information, and more within Web3 experiences, apps, and games.

**Good RPC services:**

- Make dApps & smart contracts load faster and *work*
- Ensure dApps stay up and operational
- Provide accurate results for read/write data
- Create a seamless, positive UX

Below, we’ll explore why more developers are moving to Ankr for their blockchain infrastructure needs and why we are leading the pack in service quality – based on neutral, hard data.

## Ankr’s Infrastructure Was Built From The Ground Up

Most Web3 infrastructure providers use AWS data centers exclusively to house their nodes. Web2 cloud and database technology often falls short when attempting to deliver quality blockchain RPC/API services. The requirements of decentralized systems are much better served by infrastructure that has been customized and built specifically to serve unique demands. Using AWS limits the global distribution of nodes and leads to higher latencies. It also creates a big problem if [AWS goes down](https://www.techradar.com/news/live/aws-is-down-again-heres-all-we-know) as all of the dApps that depend on these nodes to communicate with the blockchain go down with it.

On the other hand, Ankr has spent years building our server/node infrastructure from the ground up, customizing it specifically for the demands of Web3:

**Other providers**

- Provide a cloud-based service using AWS
- Constrained to AWS data center locations
- Complexities of Web3 tech bog down servers with traditional data validity requirements

**Ankr**

- Serves requests from a high-performance blend of bare-metal and cloud servers globally
- In more global data centers in more locations than any provider
- Runs nodes on custom servers optimized for blockchain & our tailor-made software

## More Web3 Projects Are Using Ankr

**Quick 2022 stats:**

- Ankr grew by 2,000% in serviced RPC requests
- 8 Billion daily RPC requests served
- Dozens of networks & testnets supported
- 40,000 distinct developers
- 30+ global regions with nodes serving traffic

## Faster Speeds

The map below shows where Ankr is outperforming our main competitors by providing extremely low-latency RPC connections. **The blue circles show where Ankr performs better in terms of response times measured in milliseconds** (in every global region) and the number of chains we are providing faster times for. Keep in mind that the radius of the circles isn’t showing coverage areas – only where the nodes are located. Any dev or Web3 application can reach Ankr’s infrastructure from anywhere in the world with an internet connection

![map.png](/uploads/map_7819c5bda9.png)

*Sourced from our internal measurement tool in Grafana that uses neutral comparison data collected from Ankr, Infura, Alchemy, Chainstack, and Quicknode over 30d prior to Dec. 15.*

Ankr has some of the lowest latency RPC connections in the industry that consistently test faster than our competitors in more locations and with more chains. But we use our internal testing tools primarily to constantly improve our services and identify any areas where we fall short.

![chart 1.jpg](/uploads/chart_1_6d5e4aa5f5.jpg)

*This graph shows the average latency in milliseconds (ms) for all blockchains, requests, and global regions for the past 30 days (from Dec 8th) using data from our internal Splunk dashboard.*

![chart 2 .png](/uploads/chart_2_86ea430a28.png)

*This graph shows the breakdown of the number of global regions x the number of blockchains that Ankr scored the best globally for speed for 24h on Dec 15.*

As a note, all latency experiences are highly dependent on any developer’s physical location. You can test how providers stack up in your specific location by using our [RPC Latency Comparison](https://rpc-comparison.vercel.app/) tool at any time. When using the comparison tool, remember that response times are highly variable and may change drastically every time you refresh. An hourly, daily, or weekly average latency (as shown in the graphs above) gives a more accurate and useful depiction of the data.

Additionally, there are some very significant advantages Ankr has in certain global regions where other providers simply cannot provide the same low latency due to the location constraints of their infrastructure. **By Average Latency, across all our supported chains, Ankr tested significantly faster than all competitors in regions outside the US.** For these results, it is important to understand that none of the providers have as broad of a selection of blockchains as Ankr, and these are overall statistics gathered as a global aggregate.

Speed is only one measurement of Web3 infrastructure. Sometimes who the “winner” is when it comes to speed comes down to a matter of 10ms – which is mostly negligible when it comes to the actual end-user experience. Although Ankr is outperforming other providers in the critical regions above, we also provide an exceptional level of service in every other category.

## More Reliable

In Web3 infrastructure, RPC service reliability is measured in areas like node uptime that are well-indicated by failed request percentages. Across all chains, Ankr’s infrastructure is currently logging around 1 failure per 100k requests. If a request reaches a node that experiences an outage or an error, our intelligent load balancer automatically re-routes the request to another node quickly.

Ankr consistently performs at the highest standards of uptime for providers. We have the added benefit of being more resistant to outages that affect centralized cloud providers from time to time as we use a unique blend of both bare-metal and cloud servers from Ankr and independent node providers.

## More Affordable

![736_-_Centralized_vs_Decentralized_Pricing_at_Scale.png](/uploads/736_Centralized_vs_Decentralized_Pricing_at_Scale_4516a97794.png)

*Estimated price comparison from May 2022*

Ankr provides developer-first, pay-as-you-go pricing for Premium RPC services at competitive rates across all supported chains (the pricing per request method is the same for all EVM-compatible chains). More than that, we are transitioning to a model that shares all RPC revenue with independent node providers, creating a more collaborative and decentralized way to serve blockchain traffic.

The graph above shows a price comparison of how much it would have cost SpiritSwap to make 8,590,000,000 requests using each provider (a real monthly figure for their usage of Ankr’s RPCs). You can see that Ankr charges drastically lower rates than our main competitors. Ankr also has a plan in place to deliver 70% of the pay-as-you-go RPC revenue coming to Ankr Network nodes to our node providers and token stakers. Out of the 70%, 49% will go to the individual stakers, and 21% will go to the node providers, as outlined further in [our whitepaper](https://www.ankr.com/ankr-whitepaper-2.0.pdf).

**Want to compare with other providers? Check our [pricing chart](https://www.ankr.com/docs/rpc-service/pricing/) to see our costs for dozens of request methods.**

## More Supported Chains Than Any Provider

![resize 1.jpg](/uploads/resize_1_e595e817a9.jpg)

Ankr supports more chains than any other provider at 23+ Proof-of-Stake chains, with many more on the way. We believe that the future is multi-chain, and we’re doing everything we can to ensure that developers have easy access to as many chains as possible, so they have more options when it comes down to choosing where to build. As a Web3-native company, Ankr has formed strong partnerships with the foundations associated with these blockchains while providing expansive open-source support.

**[See all supported chains](https://www.ankr.com/protocol/) by visiting our RPC dashboard.**

## Vast Global Distribution

![map2.png](/uploads/map2_25fce43466.png)

*This map shows 24h of global user requests. Ankr places nodes strategically in all regions to ensure extremely fast speeds for all users.*

Ankr serves blockchain requests from any location with incredibly low latency, thanks to our broad node locations in now [over 30 regions](https://medium.com/ankr-network/supporting-more-regions-than-any-web3-infrastructure-provider-8e8bd3639db9) **(more than any web3 infrastructure provider)**. Ankr’s infrastructure uses a highly effective blend of both bare-metal servers in colocation data centers around the world and cloud providers. And, since Ankr will begin onboarding increasingly more independent node providers (see the section below), we will be able to diversify our distribution even further.

## Superior User Experience

Ankr’s RPC dashboard is incredibly accessible, allowing ungated access to copy and paste endpoints for immediate blockchain connections. No login, email signup, data surrendering, or other blockers stand in the way. The interface itself is clean and extremely easy to use, with all infrastructure data, usage data, and other pertinent data neatly laid out for users. To access Premium services, users have the choice of  signing in with wallets like MetaMask or using Google sign-in with the ability to pay-as-you-go with ANKR tokens or with a credit card. We’ve even included an integration assistant with code snippets that are easily copy/pasteable for devs and available in a variety of programming languages.

## Enhanced Decentralization

Ankr has long had a track record of having a distributed node infrastructure to help protect against the vulnerability of housing all nodes with one cloud provider like AWS. But now, Ankr is shifting increasingly to decentralizing its services by welcoming many more independent node providers to serve RPC traffic from our load balancers.

![0_YppLdGFrVMg_v7YH.png](/uploads/0_Ypp_Ld_G_Fr_V_Mg_v7_YH_697c8f96a4.png)

Having a [decentralized infrastructure](https://blockworks.co/ankr-moves-to-decentralize-node-infrastructure-with-staking/) for the decentralized web is extremely important. Ankr is taking a big step to disrupt all infrastructure services (including our own model) by decentralizing. Ankr 2.0, as described in our new whitepaper, is a plan to build a completely decentralized and collaborative node infrastructure for Web3. Ankr Network has already begun onboarding many independent node providers that are serving thousands of blockchain requests as you read this:

- Pocket Network
- Harmony
- IoTeX
- Chainstack
- Fantom Foundation
- QuickNode.com
- And more!

**Our transition to decentralize Ankr’s RPC services can be found in [our new whitepaper](https://www.ankr.com/ankr-whitepaper-2.0.pdf).**

## Final Notes

In 2023, Ankr will continue boosting our performance for every chain by improving the node distribution, hardware, software, and all other aspects of the service. We will also continue our work in providing every public good possible for Web3 developers so they can build the future generation of dApps that welcome millions more to the new web in the coming year.

Ankr Leads the Pack In Blockchain RPC/API Services: A Year of Outstanding Performance

If you are just beginning your journey into the world of Web3 development, you may have come across terms such as "RPC" and "API" and wondered what these words mean. Here is an explanation of what each of these terms signify, how they are related, and the differences between them. Additionally, you will get a better understanding of the role these concepts play in the Web3 development world. Let's begin!

# RPC vs. API

Let's start by examining what Remote Procedure Call (RPC) is. It is a protocol that allows one computer or program to communicate with another computer or program from a distance. In basic terms, it allows you to access a network.

The client must begin the process by sending a message to a remote server. Upon receiving the message, the server will respond, after which the client will resume its original process.

API stands for Application Programming Interface, which allows one computer or system to communicate with other computers or programs over a shared network. Once connected to the network, APIs make it possible for the devices to interact with each other.

It is common to hear people using the terms RPCs and APIs interchangeably, but they are different. APIs provide the basis for two machines to interact on a network, allowing for data to be passed between them. RPCs are the calls made between the two computers, where the API provides guidance on how to use the calls effectively.

The main difference between RPCs and APIs is that RPCs link you to a network while APIs allow you to interact with other machines on the network.

# An Example of RPCs and APIs

An example can help to demonstrate the subtle difference between RPCs and APIs. RPCs connect to a network and APIs interact with other computers or programs on that network. Essentially, RPCs are local while APIs are communicative.

Let's take a look at another case. Suppose you sent your mom an email to ask her to make some cookies for you. This can be thought of as an RPC. You (the customer) sent a request for cookies to your mom (the server). Your mom does the necessary baking, and then sends you the cookies to fulfill your request.

If you choose to get a pizza and your mom doesn't have the ingredients, you must go to a pizzeria. Just like when you go to the pizzeria, you don't have access to the kitchen ingredients, but you can place an order. The menu provides the pizzas available for ordering along with the toppings and other options you can choose from. This is an example of an application programming interface (API).

An RPC is a specific request for information on the blockchain, whereas an API is like a framework for complex communication.

# RPCs and APIs in Blockchain

In order to communicate with blockchain networks, Web3 developers need to use either Remote Procedure Calls (RPCs) or Application Programming Interfaces (APIs). These are tools that allow developers to remotely connect to existing blockchain nodes, rather than having to set up and operate their own nodes.

In both Web2 and Web3 contexts, the relationship between RPCs and APIs remains similar, differing only in the underlying infrastructure. Specifically, RPCs provide the connectivity to a blockchain network, while APIs allow for interaction with other nodes on the network.

RPCs allow Web3 developers to communicate with distant blockchain nodes by sending data requests. As an example, Web3 wallets can utilize an RPC endpoint to request information from blockchain nodes.

RPCs can be used to query the blockchain for the information required to answer questions such as 'how many X tokens are in Y wallet?' and 'does this user have enough X tokens to cover the gas fee for this transaction?'.

If you need to write and read information to the blockchain, a full API that allows for the exchange of data between nodes in the network will be required. When you use a DEX to swap cryptocurrencies in your wallet, for example, you must write data to the blockchain with the updated balance. Additionally, APIs will be necessary if you're constructing a dApp which is constantly communicating with blockchain networks, not merely requesting data.

# Ankr’s RPCs and APIs

How does Ankr contribute to this process? Ankr provides the resources needed to construct the restaurant that makes cookies and pizza. It furnishes access to a global, decentralized, distributed network of separate node suppliers via Ankr Protocol. You can connect to Ankr Protocol either by Remote Procedure Call or Application Programming Interface.

Ankr Protocol offers public RPC endpoints which allow users to send and receive transactions directly from https://www.ankr.com/. These endpoints are available in the US and EU and are perfect for use with MetaMask. Simply plug these into your wallet and start sending and receiving transactions today.

If you're a developer or protocol looking for powerful API connectivity to power your project, Ankr offers a Premium Plan that includes unlimited requests with no rate limits. Ankr enables users to connect to blockchain nodes all over the world with the lowest latency possible.

**Ankr makes Web3 work behind the scenes by connecting devs & decentralized apps to blockchains via RPC/API services.**

In Web3, it can be a real challenge to keep up with technology that is literally updating every day. With as many facets and projects as there are with dApps, DeFi, DAOs, Layer-1s, Layer-2s, bridges, NFT marketplaces, and so much more, **it’s hard to keep track of what makes it all work.**

So what about the infrastructure that makes it all work behind the scenes? Just like the internet, there is a huge need for infrastructure to make the decentralized applications of Web3 possible. For you to even be able to read this article online, there are many levels of things happening in the Web1/Web2 background. If you searched Google for “what is an RPC” and wound up here, your screen is only populated with this information because your browser was able to establish a connection to your Internet Service Provider, the Domain Name Server, various data centers, and internet hosting services, all within a fraction of a second.

All of these processes are happening in Web3 as well – but there are extra layers on top of this that enable the blockchain elements that are key to the technology. **In order for decentralized applications to function, they need to connect to the information held on various blockchains.** For dApps, wallets, and other Web3 apps to know the contents of your wallet address, verify asset ownership, or execute critical tasks like crypto transactions, they need to connect to blockchains to pull this data. Let this article be your guide to how this all works in the background.

## Ankr: Connecting Developers, Apps, Wallets, and the World to Web3

### What Is A Blockchain Connection or RPC (Remote Procedure Call)?

RPCs could be classified as a type of API (application programming interface) that allow developers and their apps to both read data from blockchains and run code that can be executed on servers (nodes) remotely. And when developers build dApps that are connected to RPCs, the app will be able to connect users’ requests for information from blockchains and initiate tasks like crypto transactions. For instance, when users access a dApp or DEX to make transactions, their requests go through an RPC to connect them with the nodes that hold the data from blockchains so they can send new transactions to the mempool where they wait to be sent to validator nodes so they can be added to the chain. RPCs can likewise pull any data that a dApp might need from any epoch in a blockchain, including block numbers, accounts, balances, gas, mining data, and all other immutable info stored as a part of the blockchain.

**[Get started](https://www.ankr.com/rpc/) using Ankr’s RPCs for 20+ blockchains.**

### How Does An RPC Service Provide Blockchain Connections?

Today, [Ankr Network](https://www.ankr.com/rpc/) handles over 8 billion “RPC calls” to blockchains daily. These calls are simply requests coming from different Web3 developers and decentralized applications needing access to blockchain data or wanting to initiate a transaction. Specific types of these requests are referred to as “methods” such as eth_getBalance (find the balance of a wallet address) or eth_estimateGas (provides an estimate of how much gas is needed for the transaction to complete).

As you can imagine, these types of requests would be very useful as a part of the basic functionality of a wallet such as MetaMask or Trust Wallet. As a user of the wallet, you will obviously be wanting to know your balance on different chains and how much you’ll need to pay in gas to send some ETH to a friend for example. **RPCs are the magic messengers between applications and blockchains that make these actions possible.**

### How Do Web3 Applications Use Ankr’s Blockchain Connections?

Ankr connects RPC request calls automatically to the best nodes available that are running on our dozens of supported blockchains and testnets.

Here’s a breakdown of the process:

-  A developer or application makes a query to the desired blockchain like eth_getBalance by using one of our “endpoints.” The endpoint is simply a Uniform Resource Locator (URL) that provides the location that the data should be retrieved from.

In this image, the endpoint is **https://rpc.ankr.com/eth** and it is being used to request the balance from the wallet address 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 (vitalik.eth).

 ![code.png](/uploads/code_542fbdd184.png)
 
-  The request (or query) is then sent to the closest instance of Ankr’s intelligent load balancer. The load balancer is responsible for routing request traffic to the best available nodes on chains like Ethereum, ensuring that none of them are over or under worked.

-  Once the request reaches one of the full or archive nodes running on the specified blockchain, the desired data will be pulled and delivered back to the dev or application that asked for it. The new data can then be used to inform an application’s front end, so you can see things like how much ETH you have stored on the Ethereum blockchain on your wallet’s interface.

**Keep in mind that Ankr alone serves approximately 92,000 of these requests every second.**

The graphic below shows a simplified illustration of this process. Ankr’s users connect to nodes via endpoints available on the Ankr Network RPC platform to reach nodes around the world that deliver the information that they need to operate.

## What Are RPCs Used For In Web3?

**Creating decentralized applications**

One of the main use cases for RPCs is building dApps that have the capability to interact with one or more blockchains. Decentralized applications are based on smart contracts that enable features like automatic or “permissionless” executions of tasks like crypto trades on a user interface accessible to everyone. The RPC layer built into a dApp’s code allows it to communicate with as many different blockchains as it needs to satisfy its core function, which could be gaming, finance, social, or anything else.

**Connecting to blockchain data without access to your own nodes**

Developers only have a few options if they need access to on-chain data. They can either set up all their own nodes themselves and take on all the equipment maintenance and server problem-solving, or they can use a provider like Ankr for RPC services. The latter is most often the easiest, fastest, and most affordable solution to gain instant access to blockchains.

**Simplifying the building process**

RPC services are extremely useful when building Web3 applications as they can greatly simplify the job of developers. For instance, if you wanted users to be able to view their Web3 wallet’s crypto balance within your new DeFi protocol instead of building a new wallet from scratch – you would just need to access an API that can ask to communicate with the wallet to find what the user holds. At the same time, the software that forms the crypto wallet can contain API-enabling code that allows interoperability with many other DeFi protocols. To further simplify and streamline building, [Ankr’s Advanced APIs](https://www.ankr.com/advanced-api/) are an extension of our RPC services that cache and pre-package info from the most popular request methods to make the data accessible at near-instant speeds.

**Creating WebSockets to view real-time transactions data**

WebSockets are APIs that allow for a constant exchange of information between a client and a server. Since they keep the communication channel open and flowing, there is no need to establish a connection every time a message is sent. These are extremely useful for high-throughput applications such as GameFi or Internet of Things (IoT) capabilities that need to send and receive huge amounts of data.

**Run calls to access a massive amount of information**

Developers can run calls to execute tasks like encrypting wallets, producing a human-readable JSON object, finding current block size, creating multi-signature addresses, and much more. These are critical pieces of information that builders need to create their own blockchain platforms and services. With access to multi-tiered (scalable), readily available, and reliable RPCs, developers will be able to build faster and make more efficient applications.

What Do Infrastructure Providers Do? We Connect the World to Web3

![Medium Post_23.11.jpg](/uploads/Medium_Post_23_11_bbfba3412f.jpg)

**Ankr helps new Layer-1 chains get up and running with all of the infrastructure and tools they need to thrive and reach a growing developer audience. See all the ways Ankr has become a launchpad for ecosystems.**

As Ankr provides so many different Web3 infrastructure solutions, we have quickly become the first stop for new chains that need the tools, blockchain RPC connections, and added engineering expertise from our team. Ankr has become the go-to source of development solutions for blockchains and foundation teams like Polygon, BNB Chain, Klaytn, Sui, Aptos, and many others. We’ve accomplished this by providing everything new ecosystems need to operate successfully with **infrastructure that multiplies their power to attract new developers and projects.**

## Public + Premium RPC Services for a Bountiful Developer Environment

![1.png](/uploads/1_77c49bb456.png)

Having a publicly available RPC service is critical for new chains to attract as much development as possible as it makes it drastically easier to build new projects with:

- Public (freely available) RPC endpoints providing an instant gateway for developers to copy/paste endpoints directly into their project code.
- An easy way for builders to call 20+ blockchains with no need to go through the expensive and time-consuming process of establishing their own full nodes.
- A geo-distributed RPC comprised of blockchain nodes running worldwide for incredibly low-latency and reliable connections, meaning more stable and dependable dApps.

**As a Web3-native project with partnerships with so many PoS chains and foundations, Ankr has become a routine first stop for those who need a publicly available RPC service that allows their developers to build easily on new blockchains.** PoS ecosystems have come to trust Ankr as no other team has such vast experience in both running and improving node infrastructure with a dedication to providing public goods.

Ankr’s RPC (Remote Procedure Call) Service is critical Web3 infrastructure that acts as a messenger or blockchain router relaying on-chain information between nodes, dApps, and ultimately end-users so they can execute necessary tasks like transactions, populate wallet balances, fetch ownership information, and much more. It provides a simple way to start building Web3 applications and then scale them with Premium services for nearly unlimited requests, dedicated endpoints, WebSockets, Advanced APIs, and more tools.

## Advanced APIs for Indexed Data & Faster Ecosystem dApps

![2.png](/uploads/2_4231ff27b9.png)

Ankr’s Advanced API service is a collection of RPC methods that were created to simplify querying blockchain data of all types. Advanced APIs help developers build on Web3 in the most efficient way possible so they can:

- Make fewer RPC requests
- Spend less per request
- Query multiple blockchains at once
- Make multichain dApps many times faster

Ankr’s Advanced APIs streamline this process by making the blockchain data you need easier, faster, and more cost-efficient to retrieve. **The Advanced APIs take blockchain data and optimize, index, cache, and store it to make it readily accessible** for all of the most popular types of incoming requests across 8 different chains. This all has the end result of letting apps connected to the Advanced APIs provide a much faster and more efficient experience.

## Liquid Staking & Stablecoin Solutions for Free-Flowing Assets

![3.png](/uploads/3_4dc98113a5.png)

Liquid staking frees up the value of staked assets so it can be further spread throughout ecosystems’ TVL in DeFi and beyond. As Liquid Staking helps solve the capital inefficiency problem of Proof-of-Stake networks, it offers a way to earn additional rewards on staked assets for users.

**Liquid staking provides ecosystems with:**

- An easier, more flexible way to stake assets to support the network (incentivize staked TVL)
- Boosted yields and increased participation in ecosystem DeFi protocols
- Enhanced decentralization in their validation efforts with Ankr and independent validators

**Powering ecosystem stablecoins and rewards with liquid staking**

In addition to the above benefits, Ankr’s liquid staking solutions provide the rewards that power decentralized stablecoins on the BNB Chain ([Helio](https://helio.money/)) and stable asset lending on Polygon ([Sikka](https://sikka.money/)). This allows protocols like these to overcollateralize their assets with price stability that is backed by additional yield-generation opportunities. This provides mechanisms for safer borrowing, lending, and savings that are important to the financial infrastructure of all ecosystems.

## A Complete Engineering Solution for Building Dedicated Blockchains

![4.png](/uploads/4_b29fd18393.png)

Ankr has seen a growing demand for projects that need all the bandwidth and scalability that comes with having their own blockchain. Ankr has already claimed the title of infrastructure partner for the top PoS ecosystems that are offering sidechain solutions like Polygon Supernets, BNB Application Sidechains, and Avalanche Subnets. Building your own AppChain with Ankr unlocks a variety of benefits found in no other Web3 development option:

1. **Enhanced Scalability** - AppChains are dedicated blockchains that serve only one application: yours. Scale your traffic to accommodate nearly any number of users.
2. **Customizable Features** - AppChains are highly customizable for tailored programming languages, consensus mechanisms, development frameworks, and security features to suit any industry or use case.
3. **Superior User Experience** - Benefits like low (or zero) gas fees and fast transaction speeds ensure your users will be happy using your application.
4. **Streamlined Building & Launch Plan** - Ankr AppChains is an end-to-end engineering solution for creating your dedicated blockchain with every building block taken care of. Our Exchange Readiness Program helps projects get their tokens listed on major exchanges and get out in the world faster.
5. **Recurring Revenue Stream** - Become a network owner, not a renter. Collect a cut of global gas fees from the validation process and create a revenue stream to power your project.

## A Full Suite of Developer Tools To Satisfy Nearly Any Use Case

![5.png](/uploads/5_7f56a0f7b4.png)

In addition to all of Ankr’s building blocks for new blockchains, we offer the most comprehensive set of multichain tools on the market. Open-source tools like Ankr’s Gaming SDK provide Web3 GameFi use cases a way to take any existing video game (built with Unreal or Unity) and give it full blockchain and crypto functionality. Tools like Ankr Scan make it easier to find multichain data by searching once for information across several chains. Ankr is continuously releasing tools like these that make it easier than ever to build a new generation of dApps that rival anything we’ve seen in Web3 before.

Providing An End-to-End Launch Solution for New Layer-1s

![Medium Post_02.12 (1).jpg](/uploads/Medium_Post_02_12_1_a8977f304d.jpg)

Ankr identified a hack on Dec. 1st, in which malicious actors accessed the developer private key and altered the smart contract for our BNB liquid staking token (aBNBc). After internal research and assessment, we estimate the damage to be $5m worth of BNB across liquidity pools in various DEXes. Ankr has already restored security and will promptly compensate affected liquidity providers.

“*Thanks to the fast actions from the Ankr team and various protocols, we were able to minimize any damage done extremely quickly. Hacks and exploits from bad actors like this are an unfortunate possibility in Web3, even with every attention to detail in security processes – but we were well prepared. Unlike previous events in the space this year, we are doing the right thing by our community and ensuring that this is taken care of immediately with lost funds restored.*”

– Chandler Song, Co-Founder & CEO, Ankr

### **What happened?**

The exploiter was able to leverage the smart contract for the aBNBc token to create an infinite amount of this token and then exchange it for USDC. The aBNBc token represents a staked version of Binance's BNB token that earns rewards from validation efforts.

The aBNBb smart contract was safe from third-party minting prior to the attack, however, the attacker was able to obtain access to the deployer key. The attacker then uploaded a new aBNBb contract that included an extra method to mint without authorization checks. The attacker minted an excess of aBNBb out of thin air and rapidly moved to swap it out for other tokens on decentralized exchanges.

The address 0xf3a used the infinite mint bug in Ankr's contract code to mint a total of 60 trillion aBNBc across 6 different transactions. The attacker was able to swap some for the stablecoin USDC and began moving them off of the Binance Smart Chain and onto Ethereum before the transactions were flagged. The Ankr team confirmed that the losses incurred are in the region of $5 million in BNB. No other liquid staking tokens or Ankr products have been affected. Likewise, Ankr’s validators, RPC API, and AppChain services continue to operate without any disruptions.

**As this occurred, Ankr simultaneously:**

1) Alerted known off-ramps to implement their emergency plans (minimum: halt trading).

2) Secured the smart contracts with a new key to prevent any further tampering.

3) Updated smart contracts and systems to temporarily pause the movement of the underlying collateral (BNB) to be safe.

### **What are the next steps for Ankr?**

The team at Ankr is working hard to resolve this issue completely and efficiently. We have taken the necessary steps to offset the loss of funds and resolve the attack.

- We are identifying all those who provided liquidity to DEXes and all protocols supporting aBNBc or aBNBb LP, as well as aBNBc collateral pools (Midas, Helio) and we will notify all affected parties.
- Ankr will purchase $5 million worth of BNB and use this to compensate the liquidity providers that have been affected by the exploit due to the drainage of liquidity pools. We understand diluted aBNBc was speculatively traded after the exploit occurred, but we are only able to compensate LP’s caught off guard by the event.
- We are discontinuing aBNBc and aBNBb tokens effective immediately, and new ankrBNB tokens will be minted and airdropped to affected aBNBc and aBNBb users.
- We will use a snapshot and airdrop the newly-released ankrBNB tokens to all valid aBNBc holders before the snapshot. User collateral is safe with all of BNB collateral.

### **What should you do as a user?**

**To mitigate risks, Ankr is issuing the following guidelines for liquidity providers:**

1. Do not trade aBNBc or speculatively buy it at a discount. 
 
2. Our snapshot taken on Dec-02-2022 12:43:18 AM +UTC will identify you if you are an affected LP.

3. Wait for the ankrBNB airdrop, which will be proportional to the amount of aBNBc and aBNBb that you held. ankrBNB will be redeemable against staked BNB.
 
This action plan allows the team at Ankr to more rapidly restore value to legitimate token holders while also accelerating the planned migration to an upgraded contract.

At this stage, all necessary precautions are being taken to promptly resolve the situation and restore lost capital. As mentioned, Ankr will purchase $5m worth of BNB to compensate previous liquidity providers that have been affected by the exploit due to the drainage of liquidity pools.

Ankr understands the concern this has created within the community and will continue working to mitigate the situation and prevent future similar incidents.

Please note that, at this time, all user funds and underlying staked assets are safe. All aBNB users will retain their positions from before, including staked LP Tokens in Farms and accumulation of rewards during that time for doing so.

The aBNBc Token Report: Security Updates Applied & Compensation for Affected LPs

![original staking.jpg](/uploads/original_staking_1c44ac22a6.jpg)

***Everything you need to know about Ankr’s move to rename all reward-bearing tokens and discontinue support for reward-earning tokens to streamline users’ liquid staking experience.***

Today, Ankr is happy to announce that we are adopting a new nomenclature for our token model that will see the names of reward-bearing tokens change and the removal of our reward-earning tokens. This is a strategic decision we feel will best serve our community of holders, stakers and liquidity providers.

Our new token model ensures users can start using Ankr Staking easily and efficiently by removing reward-earning tokens that are still not supported across many DeFi platforms.

Currently, there are two types of Liquid Staking tokens in the Ankr ecosystem:

- Reward Bearing Tokens (c-tokens), e.g. aETHc formerly aETH
- Reward Earning Tokens (b-tokens), e.g. aAVAXb and aETHb (formerly fETH.)

The new nomenclature will see all reward-bearing tokens change names based on a new, more consistent standard. aETHc becomes AnkrETH; aBNBc becomes AnkrBNB; aAVAXc becomes AnkrAVAX, and so on.

At the same time, we are discontinuing the use of reward-earning tokens (aAVAXb, aETHb, aBNBb, etc).

There will be a period during which we will gradually stop active support of b-tokens. Holders of b-tokens can exchange them for c-tokens at any time. There will be no minting of new b-tokens and no further DeFi support.

You can read more about converting b-tokens to c-tokens in our tutorial [here](https://www.ankr.com/docs/staking/switch/switch-tokens/).

The reason for this change is the lack of support by DeFi protocols for rebase tokens in general. The benefit of liquid staking rebase tokens, such as the 1-to-1 redemption price and ability to more easily create Stable Liquid Pools with low slippage is becoming less relevant.

When compared to one year ago, there are significantly more StableSwap pools offering custom pools to accurately setup stable liquid pools for reward-bearing tokens, whose redemption price is not 1-to-1. With more than 50 liquid staking protocols available across several chains, we have been noticing that most users understand that most liquid staking tokens are reward-bearing and how to extract value from them.

## Will Any Ankr Services Be Affected by the Change?

Ankr’s services are not changing and will continue to provide everything you are used to with even more features on the way.

The name change for c-tokens will be automatic with no need for users to do anything. We feel confident it will contribute greatly to simplifying the user experience and help us make Ankr’s product message cleaner and better suited for Web3.

## What Role Do Reward-Bearing Tokens Play In Ankr Network and the broader DeFi scene?

Rewards-bearing tokens are often issued by DeFi protocols based on the service provided. This could be borrowing, lending, or providing liquidity. In the case of Ankr, the c-tokens are issued to those staking their assets using the protocol’s staking contract.

Reward-bearing tokens represent the amount of assets staked at issuance PLUS future staking rewards. The amount of reward-bearing tokens issued is always equivalent to the amount of staked assets (ETH, AVAX, BNB, etc.).

At the end of the asset staking period, AnkrETH/AnkrBNB/AnkrAVAX/etc holders can redeem their reward-bearing tokens for their original stake plus all accumulated staking rewards. The rewards accumulated by reward-bearing tokens are reflected by Ankr’s redemption price.

However, market prices on decentralized exchanges might differ from the redemption price, which is subject to an unbonding period depending on the underlying Proof-of-stake network. Selling liquid staking tokens on a decentralized exchange provides immediate liquidity, but no guarantee that the market price is the same as Ankr’s redemption price.

## Have Other Questions?

To learn more about the new token model, please visit our community channels. You can also ask any questions about the issue through our Staking Chat platform. We'll be holding a couple of AMAs in the near future so keep checking back.

Ankr announces token model change for all Reward Bearing and Earning Tokens

![IP.png](/uploads/IP_930d888117.png)

**TL;DR**

**1. Ankr doesn't store PII or have a method to correlate wallet transactions to IP addresses.**

**2. Ankr does not use our RPC to front-run transactions (MEV exploitation on your transactions).**

**3. We continue to work on our decentralization roadmap while prioritizing quality of service.**

Ankr’s goal is to provide the best possible blockchain connection experience for our builders and users. This includes an emphasis on best-in-class delivery as well as protecting user privacy. To this end, we want to clarify our IP collection policy.

## When Does Ankr Use IP Addresses?

For service delivery purposes, we temporarily record IP addresses to set usage limits and monitor for denial of service attacks against our infrastructure. Though we do look at high-level data around the success rate of transactions made over the blockchain RPC, we do not correlate wallet transactions made over the infrastructure to the IP address making the RPC request. Thus, **we do not store, exploit, or share any information regarding Personal Identifiable Information (PII), including wallet addresses.** In accordance with our privacy philosophy (as well as the terms of the Cloudflare service we use), we store IP address data only as long as it is useful to fulfill its purpose in ensuring users receive the highest quality service possible. Additionally, unlike other RPC providers in the market, we feel it’s important to clarify that we do not perform any kind of MEV from our RPC service in any way.

By design, the Cloudflare service Ankr uses is based on the same approach to [data privacy](https://www.cloudflare.com/resources/assets/slt3lc6tev37/2PpV3ceAMWJLMlXvDvGaWH/4fdc05639e8f8b664b225ab6b596d26b/how_the_cloudflare_network_maintains_data_privacy.pdf):

*“Cloudflare has no interest in what any specific individuals are doing on the Internet and has no means of connecting any one IP address to any one natural person.”*

Ankr collects IP addresses in different ways based on the user’s plan:

**Public (Free) Plans:**

- Rate limiting: Ankr must track the use of RPC services via IP address to implement request limits for our different service levels.
- GeoIP steering: To correctly serve traffic and route it to the closest data centers, it is necessary to obtain IP addresses for delivering low-latency responses.
- Service improvements: IP address data contributes to the collective internal insights Ankr gathers to improve services for customers in terms of speed and reliability.

**Premium & Enterprise Plans:**

- Premium telemetry functionality: Our paid users want telemetry data and the ability to monitor performance and resolve issues that arise.
- Rate limiting: Ankr must track the use of RPC services via IP address to ensure we can deliver approximately 1,500 requests per second limit for Premium plans.
- GeoIP steering: To correctly serve traffic and route it to the closest data centers, it is necessary to obtain IP addresses for delivering low-latency returns.
- IP Whitelisting: Ankr has a feature to limit the access of the RPC requests with a user-defined IP whitelist.

This is the minimal amount of information that is required to act as a high-quality RPC provider, but we take all possible measures to preserve user confidentiality.

## We Always Listen To User Concerns

We are continuously reviewing our policies as we listen to user feedback and adjust policies as technology changes. This is an evolving process, and our current policy terms and conditions will be updated soon. In addition, note that we do comply with court orders as is our legal responsibility as a company established in the United States. We seek continuous improvement, and we constantly review our policies to protect user privacy while retaining the functionality that is required to run a public RPC network. **As we continue to implement our roadmap to increasingly decentralize services, Ankr will keep the guiding principles of blockchain at the forefront of our products – and the privacy of our community will always be an integral part of this.**

Ankr’s IP Address Policy & Your Privacy: What You Should Know


**Ankr’s new RPC/API platform is upgrading our services offered at app.ankr.com. Learn about new sign-in & payment methods, new features, and how to get started.**

Ankr is constantly innovating and evolving our services to provide builders with everything they need to develop high-performance Web3 applications. Our first version of blockchain API services available at app.ankr.com let developers easily reach a wide variety of nodes in order to build new Web3 apps and connect them to blockchain data. Over the lifespan of this service, we’ve been finding ways to improve as well as listening to feedback from our users about how we can improve our platform. Our goal is always  to offer a more powerful method of connecting and communicating with different blockchains. Now, the end result of this process is our [new platform](https://www.ankr.com/rpc/) that delivers several benefits.

## The New Platform

Over the past year, Ankr has been hard at work building out a brand new dashboard for blockchain RPC & API services. Because we have upgraded our platform, we will be migrating all services to the new interface and **phasing out the app.ankr.com site on November 30**. To avoid any interruption to your API services, you can head to our updated [Pricing Page](https://www.ankr.com/rpc/pricing/) to find the best option for you and begin setup. Choose the best plan for you and set up a Community (Free), Premium, or Enterprise account on Ankr’s new platform today.

Check out some of the new benefits built into the platform so you can get building faster:

- **Pay As You Go plans** - We’ve implemented developer-first, pay-as-you-go pricing for RPC services at highly competitive rates across all supported chains – only pay for what you use with no oversubscriptions.
- **Faster speeds** - Ankr’s archive nodes serve requests at high speeds with extremely low latency from independent data centers worldwide. Having bare-metal servers serving requests closer to you means you get the best speeds to satisfy your users.
- **More reliability** - Our nodes maintain the highest standards of uptime, dependability, and data accuracy so your apps stay up and populated with precise information from dozens of different chains.
- **Global node distribution** - Ankr has nodes running in 30+ global regions, meaning you get low-latency connections wherever you or your users are. Additionally, nodes from other providers serve requests for a higher level of decentralization.

## New Sign-In & Payment Methods

![pasted image 0.png](/uploads/pasted_image_0_5ae89d5277.png)

Ankr is a Web3-native organization but many of our users will love the simplicity that comes with logging on via their Google account. New users can sign up and log in with Google authentication as an easy way to get started and top up their account balances with a credit card. We will soon add a way for users who have already created an account with a wallet like MetaMask to add Google auth if they wish to use it for logging in and paying in USD.

- Create an account easily with Google
- Pay in USD using Stripe
- Access all the ease of use and security features of Google

**[Create a new account](https://www.ankr.com/rpc/pricing/) in two clicks with Google.**

## New Advanced APIs

![advanced.png](/uploads/advanced_e92c4f6dc4.png)

Ankr’s Advanced APIs are now integrated right into the new RPC platform interface. The Advanced APIs were designed to streamline Web3 app development and operations by making the blockchain data you need easier, faster, and more cost-efficient to retrieve. The **Advanced APIs take blockchain data and optimize, index, cache, and store it to make it readily accessible** for all of the most popular types of incoming requests across 8 different chains (and counting). This all has the end result of letting apps connected to the Advanced APIs provide a much faster and more efficient experience.

**[Learn more](https://www.ankr.com/advanced-api/) about using Advanced APIs**

## Updates To Our Public (Free) Tier RPC

Ankr will continue offering free RPC services as a public good so builders can get to work instantly with endpoints ready to copy and paste into their code. The new platform provides **ungated access to dozens of endpoints for 20+ blockchains** and offers all Web3 developers an easy way to test RPC methods and get started building with no barriers.

Ankr has recently seen a big uptick in usage of our RPC service. Over the past two months, our RPC traffic grew by 5%. This has led some of our free users to see a change in performance if their traffic began to exceed the 1,000 requests per 10 seconds soft limit. In order to keep our infrastructure running at peak performance we need to rate limit free traffic – if your app is starting to grow traffic past the point of free request limits, then Ankr’s Premium plan provides everything you’ll need to scale affordably!

All About Ankr’s Upgraded RPC Platform

# Ankr Becomes One of the First Sui Blockchain Connection Providers

![sui.jpg](/uploads/sui_0ccc91f391.jpg)

### Ankr is now offering an RPC connection to the Sui testnet, allowing Web3 developers and apps to easily communicate with the new Move-based blockchain.

Ankr is one of the first Web3 infrastructure providers to introduce a new [RPC service](https://www.ankr.com/rpc-service/) for the highly anticipated blockchain [Sui](https://sui.io/)! This service is now available for the [Sui testnet](https://www.ankr.com/rpc/sui_testnet) and will be extended to a mainnet connection as soon as it is live (estimated early 2023). It is also compatible with the [Sui SDK](https://github.com/MystenLabs/sui/tree/main/sdk), enabling more streamlined development.

As an initial RPC infrastructure provider, Ankr will offer a connection that removes the need for developers and projects to run Sui nodes themselves with a gateway for instant communication with the network. The Sui “smart contracts platform” and Layer-1 blockchain from Mysten Labs will bring new tech and scalability benefits to Web3 developers so they can build applications with the ability to reach billions of new users with an improved Web3 experience.

This is great news for developers looking to get the jump on building on top of Sui for secure, scalable, and user-friendly dApps! You will soon be able to access endpoints for the Sui Testnet and Mainnet with free Community or pay-as-you-go Premium RPCs, make request calls, and receive information returns that are identical to the results you would get by running a Sui full node/RPC server yourself.

Once the Sui mainnet is fully released, Ankr will add support for it with additional docs, features, and tools to help our Web3 devs streamline building.

## What is the Sui Blockchain?

Sui is a Layer-1 chain created by former Meta team members who had helped create the Diem blockchain project. Sui’s novel technology upgrades and the team’s experience have landed Mysten Labs substantial funding ($300M) already secured from companies like Binance, Coinbase Labs, a16z, and FTX along with much hype from the Web3 builder community.

The Sui website heralds the new blockchain as a “Step-function change in blockchain design.” In other words, a big step up in blockchain performance and functionality with a design that is “Fast A*F” in terms of transactions per second capabilities ([120,000](https://thenewstack.io/sui-a-blockchain-built-with-smart-contracts-written-in-move/#:~:text=Sui%20also%20touts%20an%20extremely,skeptical%2C%20but%20this%20is%20also) token transfer transactions per second).

“Sui is the first permissionless Layer-1 blockchain designed from the ground up to enable creators and developers to build experiences that cater to the next billion users in web3.”

The Sui website cites several important benefits for Web3 development such as:

- Horizontally scalable, instant finality, low fees
- Parallel transaction execution
- A safe smart contract language accessible to mainstream developers
- Ability to define rich and composable on-chain assets
- Better user experience for web3 apps

## What Is Ankr’s New Sui RPC?

## 

![unnamed (1).png](/uploads/unnamed_1_afbe07d11c.png)

- Ankr’s [Sui testnet RPC](https://www.ankr.com/rpc/sui_testnet) (Remote Procedure Call) connects your wallet, command-line interface, or dApp with the Sui blockchain. It acts as a messenger or blockchain router that relays on-chain information between Sui nodes, dApps, and ultimately end-users so they can execute necessary tasks like transactions, populate wallet balances, fetch ownership information, and more.
- Sui RPC endpoints are a gateway for developers to interface directly with the Sui chain — a portal to communicate easily, remotely, and with no need to go through the DevOps of establishing their own Sui nodes.
- Ankr is providing a geo-distributed Sui RPC comprised of blockchain nodes running worldwide for incredibly low-latency and reliable connections.

[Get started now](lhttps://www.ankr.com/rpc/sui_testnet) with our free Sui testnet RPC.

## Who Is Building On Sui?

Sui has attracted a variety of DEXs, DeFi protocols, launchpads, NFT projects, social platforms, wallets, and much more. See a full list of projects currently building on Sui on their [partners page](https://sui.io/ecosystem/).

## How Do the Sui RPCs Help Developers?

Building with Sui is an excellent choice to create scalable dApps but requires access to the information on Sui nodes to do so. Therefore, Ankr’s RPC solves the following developer troubles:

- **Eliminates complex node ops** - Ankr’s Sui RPC will completely remove the need for many developers to set up their own Sui node, removing hours of time spent building, calibrating, and fixing node issues.
- **Grants access to advanced tools -**  Ankr’s Premium RPC Service instantly grants access to the best tools to build applications quickly, including:
- At least 1,500 Sui requests per second
- Dedicated Sui endpoints
- Prioritized traffic
- WebSockets (WS) capabilities
- **Powers apps and open-source software that need access to Sui** - Connect with a cluster of high-performance nodes that holds the information you need to build and operate dApps on Sui.
- **Supports the Sui network**Ankr will strengthen the Sui network globally by offering easier development and a broader, decentralized node infrastructure.

## How to Make Your First Call to Sui

You can get started now by heading to [Ankr’s RPC Service](https://www.ankr.com/rpc-service/) to make your first call! You can use the [Sui testnet endpoint](https://www.ankr.com/rpc/sui_testnet) to call the new blockchain using the standard JSON RPC methods.
