Client

To use the zkSync functionality of Viem, you must extend your existing (or new) Viem Client with zkSync Actions.

Usage

import { createPublicClient, createWalletClient, custom, http } from 'viem'
import { zkSync } from 'viem/chains'
import { eip712WalletActions } from 'viem/zksync'
 
const walletClient = createWalletClient({
  chain: zkSync,
  transport: custom(window.ethereum!),
}).extend(eip712WalletActions()) 
 
const publicClient = createPublicClient({
  chain: zkSync,
  transport: http()
})

Extensions
