# AuthorizationTempo

Utilities for Tempo-flavoured EIP-7702 authorizations.

Tempo extends EIP-7702 to support more signature types (secp256k1, P256, and WebAuthn),
enabling passkey-based account delegation. Authorizations delegate an account to a specified
implementation contract.

[Tempo Authorization Specification](https://docs.tempo.xyz/protocol/transactions/spec-tempo-transaction#tempo-authorization-list)

## Examples

```ts twoslash
import { Secp256k1 } from 'ox'
import { AuthorizationTempo } from 'ox/tempo'

const authorization = AuthorizationTempo.from({
  address: '0xbe95c3f554e9fc85ec51be69a3d807a0d55bcf2c',
  chainId: 1,
  nonce: 40n
})

const payload =
  AuthorizationTempo.getSignPayload(authorization)

const signature = Secp256k1.sign({
  payload,
  privateKey: '0x...'
})

const authorization_signed = AuthorizationTempo.from(
  authorization,
  { signature }
)
```
