| [`UserOperation.toPacked`](/ercs/erc4337/UserOperation/toPacked) | Transforms a User Operation into "packed" format. |
| [`UserOperation.toRpc`](/ercs/erc4337/UserOperation/toRpc) | Converts a [`UserOperation.UserOperation`](/ercs/erc4337/UserOperation/types#useroperation) to a [`UserOperation.Rpc`](/ercs/erc4337/UserOperation/types#rpc). |
| [`UserOperation.toTypedData`](/ercs/erc4337/UserOperation/toTypedData) | Converts a signed [`UserOperation.UserOperation`](/ercs/erc4337/UserOperation/types#useroperation) to a [`TypedData.Definition`](/api/TypedData/types#definition). |
