Chains Quickstart

This docs section provides the list of all chains available on RPC Service (opens in a new tab). Each chain in the list contains a short overview and the networks supported. It also contains info on adding those networks to MetaMask. Moreover, it outlines the API methods to interact with the network as well as the methods we don't support entirely for either Public or Premium service plans. And the cherry on top, each chain contains code snippets with basic requests in various languages and the corresponding JSON responses.

Chains supported:

Aptos

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 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.

Avalanche

Avalanche is an open-source platform for launching decentralized applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. Avalanche is the first decentralized smart contracts platform built for the scale of global finance, with near-instant transaction finality. Ethereum developers can quickly build on Avalanche as Solidity works out-of-the-box.

Avalanche is an ecosystem that features three built-in blockchains: Exchange Chain (X-Chain) (opens in a new tab), Platform Chain (P-Chain) (opens in a new tab), and Contract Chain (C-Chain) (opens in a new tab).

BNB Smart Chain

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.

BitTorrent Chain

BitTorrent Chain (BTTC) is a layer 2 scaling solution, BTTC strives to solve scalability and usability issues without compromising decentralization, and can make full use of the existing Ethereum developer community and ecosystem. BTTC is fully compatible with Ethereum, and existing applications on Ethereum can be easily migrated to this BTTC. In addition to the same experience as Ethereum, users can also enjoy ultra-high throughput and extremely low fees.

Users can conduct fast, low-cost, and safe transactions on BTTC, and assets on BTTC can be easily transferred between Ethereum, TRON, and BNB Smart Chain.

Celo

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).

Filecoin

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 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.

Nervos

Nervos blockchain, also known as Common Knowledge Base, is the rock-bottom layer of the Nervos ecosystem. As the foundation, Nervos blockchain provides trust for all the layers built on top of it. It is designed to maximize decentralization while remaining minimal, flexible, and secure. Its primary objective is to reliably preserve any data and assets stored therein.

Nervos blockchain ecosystem has a multi-layer architecture — both a Layer 1 solution (Nervos CKB) and a Layer 2 (Godwoken). Nervos CKB is a public permissionless blockchain using PoW and improved Nakamoto consensus.

Godwoken comprises two key components: the Godwoken optimistic rollup framework and the Polyjuice EVM-compatible framework. Polyjuice serves as the backend for the Godwoken rollup framework, providing an Ethereum-compatible layer atop Nervos CKB. Polyjuice leverages the account model and the scalability provided by Godwoken, and integrates evmone (opens in a new tab) as the EVM engine to run Ethereum smart contracts.

Optimism is a fast, stable, and scalable L2 blockchain built by Ethereum developers, for Ethereum developers. Built as a minimal extension to existing Ethereum software, Optimism’s EVM-equivalent (opens in a new tab) architecture scales your Ethereum apps without surprises. If it works on Ethereum, it works on Optimism at a fraction of the cost.

With the OVM 2.0 upgrade, which happened on November 11th, 2021, the Optimism protocol went through its biggest upgrade to date. The primary focus of this upgrade was EVM Equivalence, a new design for Optimism that brought it close to 1:1 parity with Ethereum.
