Addresses of the deployed contracts can be found [here](https://0xproject.com/wiki#Deployed-Addresses). + +## Usage + +### 2.0.0 + +Contracts that make up and interact with version 2.0.0 of the protocol can be found in the `src/2.0.0` directory. The contents of this directory are broken down into the following subdirectories: + +* protocol + * This directory contains the contracts that make up version 2.0.0. A full specification can be found [here](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md). +* extensions + * This directory contains contracts that interact with the 2.0.0 contracts and will be used in production, such as the [Forwarder](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md) contract. +* examples + * This directory contains example implementations of contracts that interact with the protocol but are _not_ intended for use in production. Examples include [filter](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#filter-contracts) contracts, a [Wallet](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#wallet) contract, and a [Validator](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#validator) contract, among others. +* tokens + * This directory contains implementations of different tokens and token standards, including [wETH](https://weth.io/), ZRX, [ERC20](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md), and [ERC721](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md). +* multisig + * This directory contains the [Gnosis MultiSigWallet](https://github.com/gnosis/MultiSigWallet) and a custom extension that adds a timelock to transactions within the MultiSigWallet. +* utils + * This directory contains libraries and utils that are shared across all of the other directories. +* test + * This directory contains mocks and other contracts that are used solely for testing contracts within the other directories. + +### 1.0.0 + +Contracts that make up version 1.0.0 of the protocol can be found in `src/1.0.0`. These contracts are considered deprecated and will have limited support going forward. + +## Bug bounty + +A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty). + +## Contributing + +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. + +For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein. + +Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started. + +### Install Dependencies + +If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them: + +```bash +yarn config set workspaces-experimental true +``` + +Then install dependencies + +```bash +yarn install +``` + +### Build + +To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory: + +```bash +PKG=contracts yarn build +``` + +Or continuously rebuild on change: + +```bash +PKG=contracts yarn watch +``` + +### Clean + +```bash +yarn clean +``` + +### Lint + +```bash +yarn lint +``` + +### Run Tests + +```bash +yarn test +``` + +#### Testing options + +###### Revert stack traces + +If you want to see helpful stack traces (incl. line number, code snippet) for smart contract reverts, run the tests with: + +``` +yarn test:trace +``` + +**Note:** This currently slows down the test runs and is therefore not enabled by default. + +###### Backing Ethereum node + +By default, our tests run against an in-process [Ganache](https://github.com/trufflesuite/ganache-core) instance. In order to run the tests against [Geth](https://github.com/ethereum/go-ethereum), first follow the instructions in the README for the devnet package to start the devnet Geth node. Then run: + +```bash +TEST_PROVIDER=geth yarn test +``` + +###### Code coverage + +In order to see the Solidity code coverage output generated by `@0xproject/sol-cov`, run: + +``` +yarn test:coverage +``` + +###### Gas profiler + +In order to profile the gas costs for a specific smart contract call/transaction, you can run the tests in `profiler` mode. + +**Note:** Traces emitted by ganache have incorrect gas costs so we recommend using Geth for profiling. + +``` +TEST_PROVIDER=geth yarn test:profiler +``` + +You'll see a warning that you need to explicitly enable and disable the profiler before and after the block of code you want to profile. + +```typescript +import { profiler } from './utils/profiler'; +profiler.start(); +// Some call to a smart contract +profiler.stop(); +``` + +Without explicitly starting and stopping the profiler, the profiler output will be too busy, and therefore unusable. -- cgit v1.2.3
