# Authorizations

## Overview

EIP-7702 lets an externally owned account authorize contract code to execute on its behalf. Viem
can prepare and sign an authorization or include it in a transaction.

Viem can also inspect the resulting delegation and call an ERC-7821 execution interface exposed by
the delegated account.

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

const authorization = await client.wallet.prepareAuthorization({
  address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2',
  executor: 'self',
})
```

```ts twoslash [viem.config.ts] filename="viem.config.ts"
// [!include ~/snippets/docs/viem.config.ts:setup]
