RFC: Improving WETH9 - Moving to a better Wrapped Ether Implementation

[Pandapip1]

@Philogy

Don’t see how a trusted forwarder would require less trust? Wouldn’t a ERC2771 forwarder implementing some type of ec-recover based authentication scheme also be vulnerable to quantum algorithms in the future? Not sure I fully understand the benefit.

Trustless EIP-2771

This is a pretty simple idea: instead of trusting EIP-2771 forwarders to return authorized addresses, instead, if an address would be taken, two addresses can be taken: the address of the forwarder, and the address assigned by the forwarder. For example, EIP-20 would be extended with the following functions: function balanceOf(address _ownerForwarder, address _owner) public view returns (uint256 balance) function transfer(address _toForwarder, address _to, uint256 _value) public returns (bool s…
