# getEnsResolver

Gets resolver for ENS name.

Calls `findResolver(bytes)` on ENS Universal Resolver Contract to retrieve the resolver of an ENS name.

## Usage

:::code-group

```ts [example.ts]
import { normalize } from 'viem/ens'
import { publicClient } from './client'
 
const resolverAddress = await publicClient.getEnsResolver({
  name: normalize('wevm.eth'),
})
// '0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41'
```

```ts [client.ts]
import { createPublicClient, http } from 'viem'
import { mainnet } from 'viem/chains'

export const publicClient = createPublicClient({
  chain: mainnet,
  transport: http(),
})
```

:::

:::warning
Since ENS names prohibit certain forbidden characters (e.g. underscore) and have other validation rules, you likely want to [normalize ENS names](https://docs.ens.domains/contract-api-reference/name-processing#normalising-names) with [UTS-46 normalization](https://unicode.org/reports/tr46) before passing them to `getEnsResolver`. You can use the built-in [`normalize`](/docs/ens/utilities/normalize) function for this.
