Chains & Networks

Chain and network information for use with hooks, connectors, and anywhere else you need in your app.

chain#

Object containing chains by name. Useful for creating lists of specific chains, like defaultL2Chains.

import { chain } from 'wagmi'

const defaultL2Chains = [chain.optimism, chain.arbitrumOne]

You can also import individual chains from the tree shakeable wagmi/chains entrypoint:

import { mainnet, optimism } from 'wagmi/chains'

Default Groups#

wagmi has built-in chain groups for convenience:

import {
  allChains,
  defaultChains, // mainnet, rinkeby, etc.
  defaultL2Chains, // arbitrum, optimism
} from 'wagmi'
