Building on Ethereum

The Ethereum ecosystem is one of the most popular blockchain ecosystems in existence. It has an extremely massive global community that continually builds solutions across Web3 industries like decentralized finance (DeFi), decentralized gaming (GameFi), NFTs, and more.

Some examples of DeFi solutions include lending and borrowing services, token swaps, trading, payments, and crowd-funding services. Some examples of GameFi solutions include virtual worlds, the metaverse, and play-to-earn (P2E) gaming. There is a lot of invention and disruption taking place in the Ethereum ecosystem. Ethereum is home to lots of cutting-edge development and innovation that often paves the way for Web3 development as a whole — Ethereum was the first platform to host smart contracts, dApps, NFTs, and more.

Ethereum is supported by individual nodes that make up a peer-to-peer network protocol and database. Apart from maintaining a database of transactions like other blockchains that came before it, Ethereum is responsible for the innovation of smart contracts and programmability. Ethereum is home to the world’s very first dApps.

The runtime environment for smart contracts in Ethereum is called the Ethereum Virtual Machine (EVM). Every Ethereum node runs a copy of the EVM in order to maintain consensus across the blockchain. Everyone on the Ethereum network must agree on the state of the EVM because a copy of the state has to be kept with each individual node.

All dApps that are built on the Ethereum network share a pool of computing power, which has led to strain on the efficiency and affordability of the network as the popularity and success of the network has skyrocketed. The Ethereum developer community has recently been largely focused on implementing various scaling solutions to increase the throughput and usability of the Ethereum network. One popular example of an Ethereum scaling solution are Layer-2 (L2) networks which operate on top of the base layer Ethereum protocol — processing transactions more quickly and cheaply and only periodically syncing up with the Layer 1 as necessary for security. This is just one example of how Ethereum developers are constantly working to improve and develop the network to facilitate its continued growth and adoption.

Remote procedure calls (RPCs) and how they work

Remote Procedure Call (or RPC for short) is a popular term used in distributed systems. RPCs enable computers or programs to remotely communicate with another computer or program.

For the development of dApps, RPCs are extremely helpful because developers need to seamlessly interact with blockchain networks, and they usually don’t want to deal with the hassle of running their own nodes.

With RPCs, this connection can take place remotely. In the Web3 ecosystem, the RPC model alleviates the burden of developers having to run their own physical nodes by enabling remote blockchain interaction thanks to infrastructure providers like Ankr.

Web3 wallets like MetaMask, for example, rely on RPC endpoints to request data from blockchain nodes.

These RPC endpoints facilitate connections to testnet and mainnet networks where queries can be made for blockchain data. For example, MetaMask might send a query, or a request for data, to find out how much ETH is in your wallet on the Rinkeby network (one of Ethereum’s testnets) or to determine if your wallet has a sufficient ETH balance for a particular transaction.

Ankr's Ethereum RPC

01.Ankr's Ethereum RPC allows you to connect a wallet, dApp, or command line interface (CLI) with the Ethereum network. The public RPC acts as a blockchain router or a runner that can transfer information to the Ethereum network
02.Ethereum RPC endpoints act as entry points for developers to connect directly to the Ethereum network — an interface to communicate remotely without having to bother building or running your own Ethereum node and infrastructure.
03.Ankr's Ethereum RPC is decentralized and is made up of many independent blockchain nodes that run globally. These nodes work together to serve many billions of requests from all around the world every day.
04.Ankr's Ethereum Public RPC can be used globally by anyone at any time. It requires no email signup, no credit card, or any other personal information. And, as you scale, Ankr offers a Premium Plan with more advanced tools and features.

Using the Ankr RPC as an Ethereum developer

Let’s now quickly look at how Remote Procedure Calls (RPCs) help Ethereum developers by freeing up their time and resources to focus on development rather than infrastructure.

If a developer were to use their own node to communicate with the Ethereum network, they would first have to choose the client they wish to run (which is essentially a particular version of the software), then the development environment, and other parameters.
From there, running an Ethereum node can be tough especially for beginners who are starting out with building dApps or developers thinking of scaling their apps. It often makes sense to outsource infrastructural needs in order to focus solely on developing one’s product — and this is where Ankr’s Ethereum RPC comes in.

These are some of the ways the Ankr RPC helps developers building on the Ethereum network

01.Get started immediately

Setting up a full developer node on Ethereum entails a lengthy process of initially syncing with the network for the first time. As a developer using Ankr’s RPC endpoints, you can bypass this several-day process.

02.Reliable connections

Ankr’s public RPC for Ethereum uses a backbone of globally distributed underlying nodes and an intelligent load-balancer to efficiently distribute traffic amongst them for the fastest, most efficient connections possible.

03.Ecosystem growth

Ankr’s RPC helps to speed up the growth of the Ethereum ecosystem globally by catalyzing and facilitating easy, efficient dApp development.

04.Focus on development

Without the need to set up their own Ethereum node, developers can save a lot of time that would have been spent building, calibrating, and fixing issues with nodes.

05.Flexible scaling for builders

The Ankr RPC gives developers the chance to expand and scale their infrastructure. The nodes serving Ankr’s Ethereum RPC are enterprise-grade nodes capable of handling much more traffic than at-home setups.

Ankr’s Multichain
RPC Endpoints

So far, Ankr’s multichain RPC has been globally and massively used amongst developers who are busy building the future of Web3. Ankr’s public RPC endpoints can easily serve over 80 million requests per day on a single endpoint. Here are the chains that Ankr currently supports, and links to their free, public RPC endpoints:

And more

Ankr is always working to scale our existing multichain infrastructure, while also adding support for more RPC capabilities on more blockchain networks.

You can access several other RPC endpoints with a single click from Ankr’s public RPC dashboard. You can even add RPC endpoints of your choice to your Web3 wallet, and then monitor chain activity and view analytics using AnkrScan — a multichain block explorer tool that helps Ethereum developers achieve better results while building and interacting with the Ethereum network.

APIs and use-cases

APIs, or Application Programming Interfaces, can be described as means of communication between one application and another over a shared network, thereby eliminating the need to build special connection tools.

APIs, or Application Programming Interfaces, can be described as means of communication between one application and another over a shared network, thereby eliminating the need to build special connection tools.

A very good use-case of APIs in blockchain is displaying price feeds of different cryptocurrencies. Price data is obtained from various data sources and calls have to be made to those sources to fetch the data, which is usually done via APIs. Some data sources might even rely on other data sources to update their data, which also entails the usage of APIs. But requesting data isn’t the only thing that can be done with APIs on the blockchain. For example, APIs can also be used with certain trading systems to execute sets of instructions automatically.

How Ankr’s developer APIs help builders on the Ethereum network

Ankr’s Advanced APIs are specialized APIs that developers can use to make all kinds of useful data queries in the development of their dApps.

These APIs were born out of the need for advanced functionality as requested by Ankr’s builder community to help ease development. These Advanced APIs are a collection of RPC methods created to simplify querying blockchain data. Searching for data across blockchains is hard, which is why Ankr did the heavy lifting so that developers can query on-chain data in a fast and straightforward way.

01.Query API: Search larger block ranges

It can be resource-intensive and block range-limited to query large amounts of blockchain data. With Query API, Ethereum builders can make more efficient queries and get data from the blockchain with just one call. Ankr’s Query API enables developers to easily query a range of blocks (max range is 100) for a full list of block transactions.

02.NFT API: Track tokens across chains

As the number of NFT projects and collections grows, finding details verifying the project a given NFT belongs to, past transaction history and other valuable details is a critical tool to determine an item’s value. Ankr’s NFT API makes querying NFT related data across multiple chains a simple task.

AnkrScan and it’s functionalities

AnkrScan is a multichain block explorer that currently supports 11+ chains (including Ethereum).

If you have used different blockchain explorers like EtherScan or BscScan, you may have experienced the difficulty and hassle of switching between respective block explorers.

To address this challenge, we devised AnkrScan as a solution to have multichain access from a single block explorer complete with functionalities such as analytics, search, and APIs. Imagine not having to visit multiple different block explorers on different chains to view transactions, contracts, or other on-chain data. With AnkrScan, you can query information across multiple chains simultaneously.

With AnkrScan, you can:

01.View detailed information for an individual transaction on supported blockchains.
02.View current and historical data for transactions, addresses, and blocks.
03.Have a unified view of crypto assets, tokens, and NFTs across multiple chains.
04.View a specific wallet’s transaction history.
AnkrScan is currently being improved with additional types of search parameters that enable developers to make use of indexing tools instead of searching through all transactions.

For example, one of these indexing tools entails returning all transactions for a single block rather than searching for individual transactions. This way, the process of identifying transactions across blocks is faster because the complexity and quantity of data are reduced.
