Aptos

Aptos API is available on RPC Service (opens in a new tab).

The Aptos blockchain, designed with scalability, safety, reliability, and upgradability as key principles, to address blockchain challenges, such as frequent outages, high costs, low throughput limits, and security concerns. The Aptos blockchain has been developed over the past three years by over 350+ developers across the globe. It offers new and novel innovations in consensus, smart contract design, system security, performance, and decentralization. The combination of these technologies will provide a fundamental building block to bring web3 to the masses.

Arbitrum

Arbitrum API is available on RPC Service (opens in a new tab).

Arbitrum is a side chain that runs parallel to Ethereum Mainnet. Also known as a Layer 2 (L2) scaling solution, Arbitrum improves transaction speeds and cost compared to the mainnet, making it an excellent solution for Ethereum developers.

By the Arbitrum we mean Arbitrum One which is the flagship Arbitrum mainnet chain; it is an Optimistic Rollup chain running on top of Ethereum Mainnet, and is open to all users. In an upgrade on 8/31, the Arbitrum One chain was upgraded to use the Nitro (opens in a new tab) tech stack, maintaining the same state.

Base

Base API is available on RPC Service (opens in a new tab).

Base is a secure, low-cost, developer-friendly Ethereum L2 built to bring the next billion users to web3.

Base is built on the Bedrock (opens in a new tab) release of the OP Stack (opens in a new tab), which is designed from the ground up to be as close to Ethereum as possible. Because of this, there are very little differences when it comes to building on Base and Ethereum.

However, there are still some minor discrepancies between the behavior of Base and Ethereum that you should be aware of when building apps on top of Base.

These minor differences include:

BNB Smart Chain

BNB Smart Chain API is available on RPC Service (opens in a new tab).

BNB Smart Chain (BSC) (previously Binance Smart Chain) is an innovative solution to bring programmability and interoperability to Beacon Chain. BNB Smart Chain relies on a system of 21 active validators with Proof of Staked Authority (PoSA) consensus that can support short block time and lower fees. The most bonded validator candidates of staking will become validators and produce blocks. The double-sign detection and other slashing logic guarantee security, stability, and chain finality.

To the EVM compatibility that permits support for Ethereum tools and DApps, BNB Smart Chain adds smart contract functionality to the chain. The dual-chain architecture alongside Binance Chain enables sending and receiving of BNB and BEP2 tokens cross-chain.

Celo is a mobile-first blockchain designed to make decentralized financial (DeFi) tools and services accessible to anyone with a mobile phone.

Celo is a layer 1 protocol and blockchain platform. The Celo Mainnet is entirely separate from the Ethereum network. The Celo client originated as a fork of Ethereum Go language client, go-ethereum (opens in a new tab) (or geth). Celo has several significant differences, including a Proof-of-Stake-based Practical Byzantine Fault Tolerance (PBFT) consensus mechanism.

All the crypto assets on Celo have ERC-20 compliant interfaces, meaning that while they are not ERC-20 tokens on the Ethereum Mainnet, all familiar tooling and code that support ERC-20 tokens can be easily adapted for Celo assets, including Celo Native Asset (CELO) and Celo Dollar (cUSD).

Ethereum Beacon

Available for Premium users only.

Beacon API is available on RPC Service (opens in a new tab) upon switching on the Beacon toggle.

The Beacon Chain is a consensus layer that introduced a proof-of-stake (opens in a new tab) to Ethereum. The Beacon Chain mechanism is responsible for creating new blocks, making sure those new blocks are valid, and rewarding validators with ETH for keeping the network secure.

The Beacon Chain has several clients to choose from, serving the same purpose but built with slightly different focus in mind:

Prysm (opens in a new tab) — focuses on usability, security, and reliability. Prysm is developed by Prysmatic Labs, a company with the sole focus on the development of their client.
Lighthouse (opens in a new tab) — a client with a heavy focus on speed and security. Built by Sigma Prime, an information security and software engineering firm who have funded Lighthouse along with the Ethereum Foundation, ConsenSys, and private individuals.
Nimbus (opens in a new tab) — strives to be as lightweight as possible in terms of resources used. This allows it to perform well on embedded systems, resource-restricted devices — including Raspberry Pis — and multi-purpose servers.

Fantom

Fantom API is available on RPC Service (opens in a new tab).

Fantom is a fast, scalable, and secure layer-1 platform built on an aBFT consensus protocol. Fantom is permissionless, decentralized, open-source, and fully compatible with Ethereum.

Lachesis, its revolutionary aBFT consensus mechanism, allows Fantom to be much faster and cheaper than previous technologies, yet extremely secure.

Filecoin

Filecoin API is available on RPC Service (opens in a new tab).

Filecoin is a peer-to-peer network that stores files, with built-in economic incentives and cryptography to ensure files are stored reliably over time.

Filecoin is built on top of the same software powering IPFS (opens in a new tab) protocol, which is a peer-to-peer distributed storage network that leverages content addressing (opens in a new tab) to allow permanent references to the data, and avoids relying on specific devices or cloud servers for addressing the content. Filecoin is different from IPFS because it has an incentive layer on top to incentivize contents to be reliably stored and accessed.

Filecoin enables several use cases, from Web3 native NFT and metaverse/game assets storage, incentivized permanent storage, to archiving Web2 datasets as a cheaper alternative to cloud storage.

Gnosis

Gnosis API is available on RPC Service (opens in a new tab).

Gnosis Chain (formerly xDai Chain) provides stability, scalability and an extendable beacon chain framework.

Development on Gnosis Chain is straightforward for Ethereum developers as it is an EVM compatible chain. Smart contracts can be written and deployed in the same way as for Ethereum just by setting a different RPC endpoint.

Any contract that works on the Ethereum mainnet can be redeployed to the Gnosis chain. Transaction costs are minimized, and all fees and transactions are paid with a single token (xDai). Many tools supporting Ethereum development are compatible with Gnosis Chain.
