Getting started
Pre-requirements
要在 0x-coordinator-server
上开发,请按照以下说明进行操作:
Fork this repository
克隆此存储库的 fork
确保你有 Yarn 安装。
安装依赖项:
yarn
编辑
src/production_configs.ts
文件以与您的中继器一起使用:
FEE_RECIPIENTS
- Should include the addresses and private keys of thefeeRecipientAddress
's you enforce for your orders (per chainId). Your coordinator's signatures will be generated using these private keys.SELECTIVE_DELAY_MS
- An optional selective delay between fill request receipt and approval. Adding a delay here can help market makers cancel orders without competing on speed with arbitrageurs.EXPIRATION_DURATION_SECONDS
- How long an issued signature should be valid for. This value should be long enough for someone to concievably fill an order, but short enough where off-chain cancellations take effect after some reasonable upper-bound.RPC_URL
- The backing Ethereum node to use for JSON RPC queries. Please add your own Infura API key if using Infura.
构建项目
yarn build
或构建 & 观看:
yarn watch
启动协调器服务器
yarn start
Commands
yarn build
- Build the codeyarn lint
- Lint the codeyarn start
- Starts the relayeryarn watch
- Watch the source code and rebuild on changeyarn prettier
- Auto-format the code
Database
该项目使用TypeORM。 它使任何人都可以更轻松地切换出该项目使用的支持数据库。 默认情况下,此项目使用 SQLite 数据库。
在将协调器部署到生产环境之前,请确保从 ormconfig.json
中删除以下行:
"synchronize": true,
否则数据库架构将在每次应用程序启动时自动创建。 在此处阅读更多内容。
Deployment
0x-coordinator-server
作为 docker 容器发布。 首先,安装 Docker (mac, windows)。 在构建映像之前,请确保您已按照先决条件 的第 5 步中的概述编辑了配置。
要构建图像运行:
docker build -t 0x-coordinator-server .
您可以通过运行检查图像是否构建:
docker images
启动它
docker run -p 3000:3000 -d 0x-coordinator-server

Introduction
A reference implementation of the coordinator server. To learn more about coordinators, check out the coordinator specification. To learn more about the specific design decisions of this implementation, read the design choices section.
Fork this repository to get started!
Getting started
Pre-requirements
To develop ontop of 0x-coordinator-server
, follow the following instructions:
Fork this repository
Clone your fork of this repository
Make sure you have Yarn installed.
Install the dependencies:
yarn
Edit the
src/production_configs.ts
file to work with your relayer:
FEE_RECIPIENTS
- Should include the addresses and private keys of thefeeRecipientAddress
's you enforce for your orders (per chainId). Your coordinator's signatures will be generated using these private keys.SELECTIVE_DELAY_MS
- An optional selective delay between fill request receipt and approval. Adding a delay here can help market makers cancel orders without competing on speed with arbitrageurs.EXPIRATION_DURATION_SECONDS
- How long an issued signature should be valid for. This value should be long enough for someone to concievably fill an order, but short enough where off-chain cancellations take effect after some reasonable upper-bound.RPC_URL
- The backing Ethereum node to use for JSON RPC queries. Please add your own Infura API key if using Infura.
Build the project
yarn build
or build & watch:
yarn watch
Start the Coordinator server
yarn start
Commands
yarn build
- Build the codeyarn lint
- Lint the codeyarn start
- Starts the relayeryarn watch
- Watch the source code and rebuild on changeyarn prettier
- Auto-format the code
Database
This project uses TypeORM. It makes it easier for anyone to switch out the backing database used by this project. By default, this project uses an SQLite database.
Before deploying the coordinator to production, make sure to remove the following line from ormconfig.json
:
"synchronize": true,
Otherwise the database schema will be auto-created on every application launch. Read more here.
Deployment
0x-coordinator-server
ships as a docker container. First, install Docker (mac, windows). Before you can build the image, make sure you've edited your configs as outlined in step 5 of Pre-Requirements.
To build the image run:
docker build -t 0x-coordinator-server .
You can check that the image was built by running:
docker images
And launch it with
docker run -p 3000:3000 -d 0x-coordinator-server
