Returns

Type: HexString32Bytes

The hash of the user operation (userOpHash). This hash uniquely identifies the user operation and can be used to track its status.

}

Parameters

The method accepts an array with the following parameters:

userOperation - Object: The user operation object containing the following fields:
- sender - Address: The account making the operation.
- nonce - HexString: Unique identifier for the request from this sender. For v0.7, this includes the key and sequence number.
- factory - Address (optional): The factory contract address that will deploy the smart account if it doesn't exist yet.
- factoryData - HexData (optional): The data that will be passed to the factory contract to deploy the smart account.
- callData - HexData: The data to pass to the sender during the main execution call.
- callGasLimit - HexNumber: The amount of gas to allocate the main execution call.
- verificationGasLimit - HexNumber: The amount of gas to allocate for the verification step.
- preVerificationGas - HexNumber: The amount of gas to pay for to compensate the bundler for pre-verification execution and calldata.
- maxFeePerGas - HexNumber: Maximum fee per gas (similar to EIP-1559 max_fee_per_gas).
- maxPriorityFeePerGas - HexNumber: Maximum priority fee per gas (similar to EIP-1559 max_priority_fee_per_gas).
- paymaster - Address (optional): Address of paymaster sponsoring the transaction, or null if none.
- paymasterVerificationGasLimit - HexNumber (optional): The amount of gas to allocate for the verification step of the paymaster, or null if no paymaster.
- paymasterPostOpGasLimit - HexNumber (optional): The amount of gas to allocate for the post-operation step of the paymaster, or null if no paymaster.
- paymasterData - HexData (optional): The data to pass to the paymaster during the verification step, or null if no paymaster.
- signature - HexData: The signature data.
- eip7702Auth - SignedAuthorization (optional): The EIP-7702 authorization data. SignedAuthorization Type:
```
{
    address: Address,      // addressSchema - The contract address for the authorization
    chainId: Hex,                  // hexNumberSchema transformed to Hex - The chain ID

}
```
entryPoint - Address: The entry point contract address (0x0000000071727De22E5E9d8BAf0edAc6f37da032).
