# getEnsAddress

Gets address for ENS name.

Calls `resolve(bytes, bytes)` on ENS Universal Resolver Contract to resolve the ENS name to address.

## Usage

:::code-group

```ts [example.ts]
import { normalize } from 'viem/ens'
import { publicClient } from './client'
 
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'),
})
// '0xd2135CfB216b74109775236E36d4b433F1DF507B'
```

```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 `getEnsAddress`. You can use the built-in [`normalize`](/docs/ens/utilities/normalize) function for this.
:::

### Chain-specific Resolution

`getEnsAddress` also supports chain-specific address resolution via [ENSIP-19](https://docs.ens.domains/ensip/19/).

In order to use chain-specific resolution, you must:

1. Ensure your client is configured with `mainnet` (or another L1 that supports ENS Universal Resolver)
2. Pass a `coinType` parameter to `getEnsAddress` (as seen in `example.ts`)

```ts
import { createPublicClient, http } from 'viem'
import { mainnet, base } from 'viem/chains'
import { normalize, toCoinType } from 'viem/ens'

export const publicClient = createPublicClient({
  chain: mainnet, // [!code focus]
  transport: http()
})
 
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'),
  coinType: toCoinType(base.id), // [!code focus]
})
// '0xd2135CfB216b74109775236E36d4b433F1DF507B'
```

## Returns

[`Address`](/docs/glossary/types#address)

The address that resolves to provided ENS name.

Returns `null` if ENS name does not resolve to address.

## Parameters

### name

* **Type:** `string`

Name to get the address for.

```ts
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'), // [!code focus]
})
```

### blockNumber (optional)

* **Type:** `number`

The block number to perform the read against.

```ts
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'),
  blockNumber: 15121123n, // [!code focus]
})
```

### blockTag (optional)

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

The block tag to perform the read against.

```ts
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'),
  blockTag: 'safe', // [!code focus]
})
```

### coinType (optional)

* **Type:** `number`

The [ENSIP-9](https://docs.ens.domains/ens-improvement-proposals/ensip-9-multichain-address-resolution) coin type (chain) to fetch the address for

```ts
import { base } from 'viem/chains'

const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'), 
  coinType: toCoinType(base.id), // [!code focus]
})
```

### gatewayUrls (optional)

* **Type:** `string[]`

A set of Universal Resolver gateways, used for resolving CCIP-Read requests made through the ENS Universal Resolver Contract.

```ts
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'), 
  gatewayUrls: ["https://ccip.ens.xyz"], // [!code focus]
})
```

### strict (optional)

* **Type:** `boolean`
* **Default:** `false`

A boolean value that when set to true will strictly propagate all ENS Universal Resolver Contract errors.

```ts
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'), 
  strict: true, // [!code focus]
})
```

### universalResolverAddress (optional)

* **Type:** [`Address`](/docs/glossary/types#address)
* **Default:** `client.chain.contracts.ensUniversalResolver.address`

Address of ENS Universal Resolver Contract.

```ts
const ensAddress = await publicClient.getEnsAddress({
  name: normalize('wevm.eth'),
  universalResolverAddress: '0x74E20Bd2A1fE0cdbe45b9A1d89cb7e0a45b36376', // [!code focus]
})
```
