Chains

The following Viem chains are implemented on the OP Stack:

import {
  base, 
  baseGoerli, 
  baseSepolia, 
  fraxtal, 
  fraxtalTestnet, 
  optimism, 
  optimismGoerli, 
  optimismSepolia, 
  zora, 
  zoraSepolia, 
  zoraTestnet, 
} from 'viem/chains'

Configuration

Viem exports OP Stack's chain formatters & serializers via chainConfig. This is useful if you need to define another chain which is implemented on the OP Stack.

import { defineChain } from 'viem'
import { chainConfig } from 'viem/op-stack'
 
export const opStackExample = defineChain({
  ...chainConfig,
  name: 'OP Stack Example',
  // ...
})
