Launch a relayer in under a minute. Get started here.

We are excited to release the 0x Launch Kit! The Kit includes a simple, extensible 0x relayer codebase that can be forked or used as reference material as you create your own marketplace. If you’re new to working with Ethereum, developing on 0x from scratch can be challenging and time-consuming. The Launch Kit addresses these issues and simplifies 0x integration by dramatically reducing the effort needed to add decentralized token trading to your project.

We like to draw an analogy between 0x Launch Kit and WordPress. WordPress is free, open-source software that can be used off-the-shelf to easily set up a blog and has allowed millions of publishers to flourish. However, large publishers like The New York Times or BuzzFeed need more functionality than WordPress provides, and build custom solutions to suit their needs. 0x Launch Kit is perfect for dApp developers that just want simple trade functionality, while more sophisticated teams can build custom solutions to fit their use cases.

Different software to fit different needs

The Launch Kit makes it easy to get started. Just fork the repo, run, and start making or taking orders via the Standard Relayer API. You can use this core experience as-is or write your own UI that communicates with the Launch Kit to post or serve orderbook information. When you’re ready, deploy onto a hosting service like AWS or Heroku to bring your marketplace to new users. Projects ranging from teams creating new ERC-20 tokens to indie game makers selling NFTs can use Launch Kit to quickly form secondary markets for their digital assets. This set of tools has been highly requested from 0x community members, so we are excited to see how the ecosystem uses Launch Kit to build new modes of exchange.

Check out the Launch Kit and our revamped documentation to start building on 0x today! If you need assistance or have feedback, please reach out to our team on Rocket Chat or by email at team@0xproject.com.
