### chain (optional)

* **Type:** [Chain](/docs/glossary/types#chain)

The [Chain](/docs/chains/introduction) of the Bundler Client.

### dataSuffix (optional)

* **Type:** `Hex`

Data to append to the end of User Operation calldata. Useful for adding [transaction attribution](https://oxlib.sh/ercs/erc8021/Attribution).

The bundler client will also inherit `dataSuffix` from the underlying client (e.g., wallet client) if not explicitly set.

Applies to `prepareUserOperation` and `sendUserOperation` actions.
