# prepareAuthorization

Prepares an [EIP-7702 Authorization](https://eips.ethereum.org/EIPS/eip-7702) for signing.
This Action will fill the required fields of the Authorization object if they are not provided (e.g. `nonce` and `chainId`).

With the prepared Authorization object, you can use [`signAuthorization`](/docs/eip7702/signAuthorization) to sign over it.
