This package contains the implementation of the Forwarder contract. This contract is intended to improve the UX of interacting with the 0x Exchange contract by abstracting user approvals, converting ETH to WETH, and paying fees. Addresses of the deployed contracts can be found in this 0x guide or the DEPLOYS file within this package.
