Hello from everyone here at 0x! July has been a very busy month for the team, with a focus on development tools and the community.

For those who are unfamiliar with 0x and our mission, you can find more information here:

Developer Tools

0x.js has been published as a release candidate! This release targets version 2 of the protocol. We will continue to publish release candidates up until the final release on main net. After the final release on mainnet, 0x.js and all other packages will employ semantic versioning for version numbers.

The website and developer documentation is now updated for the release candidate packages. If you’re looking for the documentation of previous versions of 0x.js, you can select it from the dropdown menu.

The Standard Relayer API for version 2 of the protocol is now finalized. We are continuing to develop an OpenAPI/Swagger definition which will enable auto-generated clients in multiple languages. Version 2 of the API now supports ERC721 via our asset type encoding scheme.

A quick recap for those who are new to the 0x ecosystem, the Standard Relayer API defines an API for relayers to share liquidity. This allows projects source liquidity from other relayers and add depth to their order book.

0x Protocol v2

Our first security audit by SoHo token labs is complete. Our second security audit with Consensys Diligence has now commenced. We’ve seen many projects in our developer channel eager to get started with version 2. An early stage starter project is available which walks through many use-cases. If you’ve previously worked with the previous version of the protocol and would prefer a technical document on the changes, we have written an upgrade guide for you.

Be sure to check out the new features in 0x Protocol v2.

User Tools

Our new 0x Portal was launched last month. In portal you can now walk through a step by step on-boarding process which will get you set up to trade on any 0x relayer.

You will also notice a list of relayers built on 0x. Each relayer tile lists the tokens that are popular and the amount of volume. Be sure to click on through to a relayer and make some trades!

The pieces which power the trade widget have been finalised and are currently under audit. Many projects are opting to design and implement their own UI using the contracts and tools. For those who would prefer a drop-in embeddable widget we’ve been giving it some design ❤. This widget will support buying both ERC20 and ERC721 tokens.

Since the blockchain can take some time to confirm transactions, we’ve introduced some additional screens to help inform the user of the progress.

Meetups and Community

The team has been traveling through Asia to meet with the wider developer community.

We attended NIFTY conference and ran a developer focused workshop. In the workshop we went through how to create a simple ERC721 marketplace built on top of 0x. The code for this workshop can be found here and the slides are also available here.

A number of teams used 0x in their hackathon project. The winner of the ZRX prize went to the STIFTIES team. It’s a marketplace for consumers to download stickers for social media and messaging apps, that are backed by NFTs. Their submission can be found over on devpost. Congrats to the STIFTIES team!

In Beijing we were invited to present at School of Economics at Tsinghua University to a group of over 60 people interested in blockchain. This presentation was an overview of 0x and the new features in the latest version of the protocol.

We co-hosted a meetup with DDex and presented 0x to a packed room full of eager blockchain developers.

There were additional meetups in Hangzhou, Beijing and Seoul. Thanks to all those that attended. Extra special thanks to those who helped us find venues and meetup spaces.

A Few New Faces

Two new members have joined the team in the last month. Firstly, Peter Zeitz who is a research fellow focused on on-chain governance. Secondly, Chris Kalani who has joined as Director of Design. Welcome Peter and Chris!

Our mission at 0x is to create a tokenized world where all value can flow freely. If you are interested and would like to join us in our mission then head over to our Careers page.
