### With Call Scopes

Use `scopes` to restrict which contracts and functions the access key can call:

### With a Witness

Use `witness` to bind a 32-byte value into the authorization's signing hash. This lets you bind a single signature to an arbitrary offchain context (e.g. a server-issued challenge), or use it as a revocation handle that can be burned onchain (via [`accessKey.burnWitness`](/tempo/actions/accessKey.burnWitness)) to invalidate the authorization before it is submitted ([TIP-1053](https://tips.sh/1053)):

### Admin Keys

Set `admin: true` to authorize an unrestricted admin key. Admin keys can manage the account's other access keys and cannot carry `expiry`, `limits`, or `scopes` (they are ignored). Requires the T6 hardfork ([TIP-1049](https://tips.sh/1049)):

```

Once authorized, an admin key can authorize (and manage) other keys on behalf of the account. Pass the admin key as the `account`: viem binds the authorization to the parent account and signs it with the admin key directly.

### Asynchronous Usage

The example above uses a `*Sync` variant of the action, that will wait for the transaction to be included before returning.

If you are optimizing for performance, you should use the non-sync `accessKey.authorize` action and wait for inclusion manually:

## Return Type

```ts
type ReturnType = {
  /** The account that authorized the key. */
  account: Address
  /** The public key that was authorized. */
  publicKey: Address
  /** The signature type. */
  signatureType: number
  /** The expiry timestamp. */
  expiry: bigint
  /** Transaction receipt */
  receipt: TransactionReceipt
}
```

## Parameters

### accessKey

* **Type:** `{ accessKeyAddress: Address; keyType: string } | { address: Address; type: string } | { publicKey: Hex; type: string }`

The access key to authorize. Accepts an `AccessKeyAccount`, or an object with `{ address, type }` or `{ publicKey, type }`.

### admin (optional)

* **Type:** `boolean`

Whether to authorize the key as an admin key. Admin keys are unrestricted and can manage the account's other access keys; `expiry`, `limits`, and `scopes` are ignored. Requires the T6 hardfork ([TIP-1049](https://tips.sh/1049)).

### expiry (optional)

* **Type:** `number`

Unix timestamp when the key expires.

### limits (optional)

* **Type:** `{ token: Address; limit: bigint; period?: number }[]`

Spending limits per token. Optionally include `period` (in seconds) to make the limit periodic — it resets after each period. Use `Period.months(1)`, `Period.seconds(n)`, etc. from `ox/tempo` for convenience.

### scopes (optional)

* **Type:** `{ address: Address; selector?: Hex | string; recipients?: Address[] }[]`

Call scopes restricting which contracts/selectors this key can call. Each scope entry specifies a contract address, an optional 4-byte function selector, and optional recipient addresses (for transfer-like functions). If `scopes` is set to `[]` (empty array), the key cannot make any calls.

### witness (optional)

* **Type:** `Hex`

Optional 32-byte witness bound into the authorization's signing hash. Can be burned onchain via [`accessKey.burnWitness`](/tempo/actions/accessKey.burnWitness) to invalidate the authorization before it is submitted ([TIP-1053](https://tips.sh/1053)).
