0x is an open protocol that facilitates trustless, low friction exchange of Ethereum-based assets. For more information on how it works, check out the 0x protocol specification.
This repository is a monorepo including the 0x protocol smart contracts and numerous developer tools. Each public sub-package is independently published to NPM.

Usage
Node version 6.x or 8.x is required.
Most of the packages require additional typings for external dependencies.
You can include those by prepending the @0x/typescript-typings package to your typeRoots config.
"typeRoots": ["node_modules/@0x/typescript-typings/types", "node_modules/@types"],
