OP Viem

Viem Extension for OP Stack Chains

🚨 DEPRECATION WARNING 🚨

With the upstreaming of most op-viem features into Viem consider this library deprecated. We recommend using Viem's native OP Stack support instead.

Features

• Simplifies cross L1 & L2 interactions
• Seamless extension to Viem
• TypeScript ready
• Test suite running against forked Ethereum network

Overview

// import modules
import { createWalletClient, createPublicClient, custom, http } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
import { mainnet, base } from 'viem/chains'
import { baseAddresses } from 'op-viem/chains'
import { walletL1OpStackActions, publicL1OpStackActions, publicL2OpStackActions } from 'op-viem'

// create clients
export const opStackL1WalletClient = createWalletClient({
  chain: mainnet,
  transport: custom(window.ethereum)
}).extend(walletL1OpStackActions)

export const opStackL1PublicClient = createPublicClient({
  chain: mainnet,
  transport: http()
}).extend(publicL1OpStackActions)

export const opStackL2PublicClient = createPublicClient({
  chain: base,
  transport: http()
}).extend(publicL2OpStackActions)

// perform an action
opStackL1PublicClient.getOutputForL2Block(blockNumber: 2725977n, ...baseAddresses)
