0x Starter Project

This project will take you through a number of scenarios using the 0x v4 protocol.

Scenarios

This repository contains a bunch of scenarios that you can run from the command-line:

Getting Started

By default this project uses the 0x development mnemonic running against Ganache. This project can be configured to use a different mnenonic and also run against Kovan testnet.

You may choose to update the mnemonic in src/configs.ts or use the one provided (note if many people use this mnemonic on Ropsten then the funds may be drained).

When changing the mnemonic ensure that the first three derived address have test ETH. You can request test ETH from https://faucet.paradigm.xyz/. The first derived address will also need test ZRX, which you can mint by running yarn mint_test_zrx.

Install dependencies:

yarn install

Build this package:

yarn build

Run a scenario in another terminal:

yarn scenario:fill_erc20_limit_order

To run all scenarios:

yarn scenario:all

All the scenarios commands can be found in the package.json's scripts section and begin with scenario:.

Switching to Ropsten

To switch between Ropsten/ganache, change the last line in src/configs.ts and re-build. Ganache is enabled by default.

For Ropsten, you'll also need to provide a value for ROPSTEN_RPC_URL in .env (copy .env.example to create .env). You can obtain an API key from Alchemy.

For Ganache:

export const NETWORK_CONFIGS = GANACHE_CONFIGS;

For Kovan:

export const NETWORK_CONFIGS = ROPSTEN_CONFIGS;

Windows Development Setup

If you're setting up Node.js for the first time on Windows, you may find the following StackOverflow guide useful. There are a few build tools required for Node.js on Windows which are not installed by default (such as Python). Please follow that guide before running through the tutorials.
