Example smart contracts that interact with 0x protocol.


Contracts can be found in the contracts directory. This package contains example implementations of contracts that interact with the protocol but are not intended for use in production. Examples include filter contracts, a Wallet contract, and a Validator contract, among others.


We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
