CallModule - Mellow

Overview

Abstract contract extending VerifierModule, implementing low-level contract calls with verification via a pluggable verifier.

`call`

function call(
    address where,
    uint256 value,
    bytes calldata data,
    IVerifier.VerificationPayload calldata payload
) external nonReentrant returns (bytes memory response)

Description

Executes a low-level call to a target contract after validating the call parameters through an external Verifier contract. The verification logic is determined by the verification type specified in the Verifier contract. For details on available verification types, refer to the Verifier specification.

Parameters

where: The address of the target contract.
value: The ETH value to send along with the call.
data: Calldata to pass to the target contract.
payload: Encoded verification payload used to authorize the call.

Returns

response: The raw returned data from the target contract call.

Requirements

All the provided parameters must be externally verified via verifier().verifyCall.
Reentrancy is prevented via nonReentrant modifier.
