* Replace assetDataUtils with DevUtilsContract wherever possible Does not replace from @0x/instant and some @0x/order-utils uses * Add revertIfInvalidAssetData to LibAssetData This is needed to replace `assetDataUtils.decodeAssetDataOrThrow`. Because it's used in packages and not only contracts, we should wait to deploy the updated contract so we can update `@0x/contract-artifacts`, `@0x/abi-gen-wrappers`, and `@0x/contract-wrappers` first. * remove usages of signatureUtils * fix test for optimised encoding * refactor @0x/contracts-integrations * update changelogs * Move @0x/contracts-dev-utils from devDependencies to dependencies It is exported as part of the package
Exchange Forwarder
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.
