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.
npm install @0x/contracts-exchange-forwarder --save
A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found here.
