# Get Resolver Address \[ens.getResolver]

Gets the resolver address for an ENS name (via the ENS Universal Resolver's `findResolver`).

## Usage

This example gets the resolver address for an ENS name (via the ENS Universal Resolver's `findResolver`).

:::code-group
```ts twoslash [example.ts]
import { Ens } from 'viem/utils'
import { client } from './viem.config'

const resolver = await client.ens.getResolver({
  name: Ens.normalize('wevm.eth'),
})
// @log: '0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41'
```

```ts twoslash [viem.config.ts] filename="viem.config.ts"
import { Client, http, publicActions } from 'viem'
import { mainnet } from 'viem/chains'

export const client = Client.create({
  chain: mainnet,
  transport: http(),
}).extend(publicActions())
```
:::

### Standalone Action

Call `Actions.ens.getResolver` directly by passing the Client as the first argument.

:::code-group
```ts twoslash [example.ts]
import { Actions } from 'viem'
import { Ens } from 'viem/utils'
import { client } from './viem.config'

const resolver = await Actions.ens.getResolver(client, {
  name: Ens.normalize('wevm.eth'),
})
// @log: '0x4976fb03C32e5B8cfe2b6cCB31c09Ba78EBaBa41'
```

```ts twoslash [viem.config.ts] filename="viem.config.ts"
import { Client, http } from 'viem'
import { mainnet } from 'viem/chains'

export const client = Client.create({
  chain: mainnet,
  transport: http(),
})
```

## Recipes

### Use a Custom Universal Resolver

Pass a Universal Resolver address to query a specific deployment. Add a block number when the resolver lookup must use historical state.

:::code-group
```ts twoslash [example.ts]
import { Ens } from 'viem/utils'
import { client } from './viem.config'

const resolver = await client.ens.getResolver({
  blockNumber: 23_085_558n,
  name: Ens.normalize('wevm.eth'),
  universalResolverAddress: '0xeeeeeeee14d718c2b47d9923deab1335e144eeee', // [!code focus]
})
```

```ts twoslash [viem.config.ts] filename="viem.config.ts"
import { Client, http, publicActions } from 'viem'
import { mainnet } from 'viem/chains'

export const client = Client.create({
  chain: mainnet,
  transport: http(),
}).extend(publicActions())
```
:::

## Return Value

`Address`

The resolver address for the name.

## Parameters

### blockNumber

* **Type:** `bigint`

Resolves against the state at a given block number.

```ts twoslash
import { Actions, Client, http } from 'viem'
import { mainnet } from 'viem/chains'
import { Ens } from 'viem/utils'

const client = Client.create({ chain: mainnet, transport: http() })
// ---cut---
const resolver = await Actions.ens.getResolver(client, {
  blockNumber: 23_085_558n, // [!code focus]
  name: Ens.normalize('wevm.eth'),
})
```

### blockTag

* **Type:** `'latest' | 'earliest' | 'pending' | 'safe' | 'finalized'`
* **Default:** `'latest'`

Resolves against the state at a given block tag.

```ts twoslash
import { Actions, Client, http } from 'viem'
import { mainnet } from 'viem/chains'
import { Ens } from 'viem/utils'

const client = Client.create({ chain: mainnet, transport: http() })
// ---cut---
const resolver = await Actions.ens.getResolver(client, {
  blockTag: 'finalized', // [!code focus]
  name: Ens.normalize('wevm.eth'),
})
```

### name

* **Type:** `string`

The ENS name to get the resolver for.

```ts twoslash
import { Actions, Client, http } from 'viem'
import { mainnet } from 'viem/chains'
import { Ens } from 'viem/utils'

const client = Client.create({ chain: mainnet, transport: http() })
// ---cut---
const resolver = await Actions.ens.getResolver(client, {
  name: Ens.normalize('wevm.eth'), // [!code focus]
})
```

### universalResolverAddress

* **Type:** `Address`
* **Default:** `client.chain.contracts.ensUniversalResolver.address`

Address of the ENS Universal Resolver contract.

```ts twoslash
import { Actions, Client, http } from 'viem'
import { mainnet } from 'viem/chains'
import { Ens } from 'viem/utils'

const client = Client.create({ chain: mainnet, transport: http() })
// ---cut---
const resolver = await Actions.ens.getResolver(client, {
  universalResolverAddress: '0xeeeeeeee14d718c2b47d9923deab1335e144eeee', // [!code focus]
  name: Ens.normalize('wevm.eth'),
})
```

## Errors

| Error | Description |
| --- | --- |
| `Errors.BaseError` | The name does not match the chain's `ensTlds`. |
| `ContractError.ContractFunctionExecutionError` | The Universal Resolver call failed. |
