The main differences between Quai’s EVM and the traditional EVM can be seen below.

​
Available Tooling

As mentioned earlier, Quai has a subset of Ethereum tooling that has been adapted to handle the multi-chain network. This tooling includes:

Pelagus Wallet

The community built wallet for Quai with support for both Quai and Qi environments.

Hardhat

A modified version of the Hardhat framework built for Quai Network.

Quais SDK

A complete Quai Network interaction library for JavaScript and TypeScript.

Local Node Runner

A containerized, feature complete local node environment for Quai.

Testnet Faucet

The central source for testnet Quai token drips.

Explorer

Track transactions and blocks on the testnet.

​
Migrating your Ethereum App to Quai

Ethereum applications are typically built with some combination of Ethers, Web3.js, Viem, and WAGMI. These tools work out of the box for web based dapp development as long as you are using Pelagus wallet as an injected provider. If you are using a different wallet or not building a web based dapp, you can still use these tools for querying chain data, however, you will need to incorporate or transition to the Quais SDK for sending transactions. The Quais SDK is a fork of Ethers v6. Because of this, syntax in Quais is nealy identical to Ethers with the caveat that the above changes have been applied. If your application is currently built with Viem or Web3.js, these guides are helpful in understanding syntax mapping of your existing code to Quais: Almost all of the existing functions and utilities in Ethers, Viem, and Web3.js have direct mappings to similar or the same methods in Quais.js, with the exception of methods that utilize provider polling.
