ERC-7579 Validation module (type 1). A module that implements logic to validate user operations and signatures.

Functions

Validates a UserOperation

function validateUserOp(PackedUserOperation calldata userOp, bytes32 userOpHash) external returns (uint256);

Parameters

Name	Type	Description
`userOp`	`PackedUserOperation`	the ERC-4337 PackedUserOperation
`userOpHash`	`bytes32`	the hash of the ERC-4337 PackedUserOperation MUST validate that the signature is a valid signature of the userOpHash SHOULD return ERC-4337's SIG_VALIDATION_FAILED (and not revert) on signature mismatch See {IAccount-validateUserOp} for additional information on the return value

Validates a signature using ERC-1271

function isValidSignatureWithSender(address sender, bytes32 hash, bytes calldata signature)
    external
    view
    returns (bytes4);

Parameters

Name	Type	Description
`sender`	`address`	the address that sent the ERC-1271 request to the smart account
`hash`	`bytes32`	the hash of the ERC-1271 request
`signature`	`bytes`	the signature of the ERC-1271 request MUST return the ERC-1271 `MAGIC_VALUE` if the signature is valid MUST NOT modify state
