Main Functionalities

  1. Signer Management:

    • onInstall: Processes installation data to update the signer's public key coordinates and emits the SignerTransferred event to log the change.
    • onUninstall: Handles the uninstallation process by updating the signer's public key to default values (0, 0) and emits the SignerTransferred event.
    • transferSigner: Updates the public key coordinates for a specified entity ID and emits the SignerTransferred event to log the update.

  2. Signature Validation:

    • validateSignature: Validates the authenticity of a signature for a specific account and entity ID, returning a magic value if valid or an invalid value otherwise.
    • validateUserOp: Verifies a user operation's signature against a specified entity, returning a status code indicating the result of the validation.

  3. Utility Functions:

    • replaySafeHash: Generates a replay-safe hash by wrapping a given hash in an EIP-712 structure, ensuring protection against replay attacks.
    • moduleId: Returns a string identifier for the module, indicating its version and type.

  4. Interface Support:

    • supportsInterface: Checks if the contract implements a specific interface, including the IValidationModule interface.
