# Set Token Role Admin \[token.setRoleAdmin]

Sets the admin role for a specific role in a TIP-20 token. Requires the current admin role for the target role. [Learn more about token roles](https://docs.tempo.xyz/protocol/tip403/spec)

## Usage

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

const { receipt } = await client.token.setRoleAdminSync({
  adminRole: 'pause',
  role: 'issuer',
  token: '0x20c0000000000000000000000000000000000001',
})

console.log('Transaction hash:', receipt.transactionHash)
// @log: Transaction hash: 0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef
```

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

### 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 `token.setRoleAdmin` action and wait for inclusion manually:

```ts twoslash
import { Actions } from 'viem/tempo'
import { client } from './viem.config'

const hash = await client.token.setRoleAdmin({
  adminRole: 'pause',
  role: 'issuer',
  token: '0x20c0000000000000000000000000000000000001',
})
const receipt = await client.transaction.waitForReceipt({ hash }).receipt

const { args } = Actions.token.setRoleAdmin.extractEvent(receipt.logs)
```

## Recipes

### Let the Issuer Team Manage Its Own Roster

Set `issuer` as its own admin so senior minting keys onboard new keys directly with [`token.grantRolesSync`](/tempo/actions/token.grantRoles), without routing every change through `defaultAdmin`.

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

const token = '0x20c0000000000000000000000000000000000001'

await client.token.setRoleAdminSync({
  adminRole: 'issuer', // [!code focus]
  role: 'issuer', // [!code focus]
  token,
})

const { value } = await client.token.grantRolesSync({ // [!code focus]
  roles: ['issuer'], // [!code focus]
  to: '0x8ba1f109551bD432803012645Ac136ddd64DBA72', // [!code focus]
  token, // [!code focus]
}) // [!code focus]

console.log('New issuer key active:', value[0].hasRole)
// @log: New issuer key active: true
```

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

### Move Pause Control Under Incident Response

Assign `pause` as the admin of both pause roles so the incident-response lead manages the on-call roster that can halt and resume transfers.

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

const token = '0x20c0000000000000000000000000000000000001'

await client.token.setRoleAdminSync({
  adminRole: 'pause', // [!code focus]
  role: 'pause', // [!code focus]
  token,
})

await client.token.setRoleAdminSync({
  adminRole: 'pause', // [!code focus]
  role: 'unpause', // [!code focus]
  token,
})
```

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

## Return Value

```ts
type ReturnType = {
  /** Role whose admin role was updated. */
  role: Hex
  /** New admin role. */
  newAdminRole: Hex
  /** Address that updated the admin role. */
  sender: Address
  /** Transaction receipt. */
  receipt: TransactionReceipt
}
```

## Parameters

### adminRole

* **Type:** `"defaultAdmin" | "pause" | "unpause" | "issuer" | "burnBlocked"`

New admin role.

### role

* **Type:** `"defaultAdmin" | "pause" | "unpause" | "issuer" | "burnBlocked"`

Role to set admin for.

### token

* **Type:** `Address | bigint`

Token to operate on: a TIP-20 token id or a contract address.

### account (optional)

* **Type:** `Account | Address`

Account that will be used to send the transaction.

### feePayer (optional)

* **Type:** `Account | boolean`

Fee payer for the transaction (TIP-1 gas sponsorship).

Pass `true` to defer the fee token to an external fee payer (e.g. a relay), or a local Account to co-sign the transaction as the fee payer.

### feeToken (optional)

* **Type:** `Address | bigint`

Fee token for the transaction.

Can be an unpaused USD-denominated TIP-20 token address or ID.

### gas (optional)

* **Type:** `bigint`

Gas limit for the transaction.

### keyAuthorization (optional)

* **Type:** `KeyAuthorization`

Signed key authorization to include with the transaction, authorizing an access key to act for the sending account.

### maxFeePerGas (optional)

* **Type:** `bigint`

Max fee per gas for the transaction.

### maxPriorityFeePerGas (optional)

* **Type:** `bigint`

Max priority fee per gas for the transaction.

### nonce (optional)

* **Type:** `number`

Nonce for the transaction.

### nonceKey (optional)

* **Type:** `'expiring' | 'random' | bigint`

Nonce key for the transaction (TIP-1009 2D nonces).

Use `'expiring'` to select an expiring nonce, which enables concurrent transaction submission without nonce ordering. Use `'random'` to select a random key.

### throwOnReceiptRevert (optional)

* **Type:** `boolean`
* **Default:** `true`

Whether a `Sync` action throws when the receipt reports a revert.

### validAfter (optional)

* **Type:** `number`

Unix timestamp after which the transaction can be included.

### validBefore (optional)

* **Type:** `number`

Unix timestamp before which the transaction must be included.
