Description

Most of the contracts have a rescueFunds() function that can rescue any funds and tokens that are accidentally send to the contract. The one exception is contract Hasher.

Hasher doesn't have any payable functions to ETH would not normally be present in the contract. Tokens could be send to this contract, but that doesn't seem very likely.

Adding a function rescueFunds() does increase the complexity so probably not worth the trouble to implement. However adding a comment in the contract might be useful (also to prevent future remaks about this).

Steps to reproduce

Expected behavior

Would expect Hasher to also have this function or have a comment why it is lacking.

Actual behavior

Tokens send to the Hasher contract can't be rescued.

Hasher.sol#L12:

contract Hasher is IHasher {

    function packMessage(...) external pure override returns (bytes32) {
        ...
    }
    // no rescueFunds
}

Socket.sol#L44-L50:

function rescueFunds(
    address token_,
    address userAddress_,
    uint256 amount_
) external onlyRole(RESCUE_ROLE) {
    RescueFundsLib.rescueFunds(token_, userAddress_, amount_);
