Custom Network Chains

Opstack Kit works with OP Stack chains. By adding viem can quickly add your chain and use it right away.

customChains.tsx

import { defineChain } from 'viem'
import { chainConfig } from 'viem/op-stack'

const sourceId = 123 // number = L1

export const customChains = defineChain({ // string = Name
  ...chainConfig,
  id: 111222333, // number
  name: 'customChains', // string = Name
  nativeCurrency: { name: 'XXX', symbol: 'XXX', decimals: 18 }, // string
  rpcUrls: {
    default: {
      http: ['https://xxxURL-RPCxxx.com'], // string = url
    },
  },
  blockExplorers: {
    default: {
      name: 'ExampleChain Scan', // string
      url: 'https://xxxURLxxx.com/', // string = url
      apiUrl: 'https://xxxURLxxx.com/api', // string = url
    },
