getEnsResolver

Action for fetching ENS resolver for name.

Import

import { getEnsResolver } from '@wagmi/core'

Usage

index.ts

import { getEnsResolver } from '@wagmi/core'
import { normalize } from 'viem/ens'
import { config } from './config'

const ensResolver = getEnsResolver(config, {
  name: normalize('wevm.eth'),
})

config.ts

import { http, createConfig } from '@wagmi/core'
import { mainnet, sepolia } from '@wagmi/core/chains'

export const config = createConfig({
  chains: [mainnet, sepolia],
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
})

WARNING

Since ENS names prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to normalize ENS names with UTS-46 normalization before passing them to getEnsResolver. You can use Viem's built-in normalize function for this.

import { type GetEnsResolverParameters } from '@wagmi/core'
