AssetProxy
This package contains the implementations of all of the AssetProxy contracts available within the 0x protocol. These contracts are responsible for decoding the assetData sent to them and performing the actual transfer of assets. Addresses of the deployed contracts can be found in this 0x guide or the DEPLOYS file within this package.
