The 0x team has been hard at work behind the scenes and we have some exciting news in this January Update.

Ledger Support in Portal + Tutorial

Our 0x Subproviders package provides support for Ledger Nano S in the Web3 Provider Engine stack. This package is now being used by multiple relayers, and we’re happy to announce 0x Portal now supports Ledger Nano S. Users of 0x Portal will be able to trade directly from their Ledger Nano S, providing greater confidence and security. Our 0x Wiki now includes a simple guide on how to add Ledger Nano S support to your application.

Ledger Nano S in 0x Portal

Order Watcher

We are excited to introduce Order Watcher, a tool we believe relayers will find extremely useful. The state of a 0x order can change for a variety of reasons, the order could be filled, cancelled or the underlying account balance can change. Order Watcher is a tool that helps relayers watch the blockchain for these changes and receive a notification. We have taken care of the various edge cases so you don’t have to. Check out our wiki article on the Order Watcher. It is best used with a specially configured Parity Ethereum node and just in case you haven’t yet deployed your own Ethereum node, we have a handy guide for that as well.

Introducing 0x Forum

We are introducing a forum open to all in the community as a way to participate in the ongoing design discussions of the 0x protocol. Feel free to drop in and join us to discuss topics like fee sharing and networked liquidity in the open orderbook model.

0x Developer Meetings

January marked the first of our ongoing monthly 0x Developer Meeting. We were joined by 20+ members of the community to discuss upcoming features to be included in 0x Protocol v2. Topics discussed included Atomic Order Matching, Non Fungible Token support and Fee Splitting. Thank you to all who made the call, we found it incredibly valuable. The full agenda and audio is available on the 0x forum. The 0x Developer meetings are scheduled on a monthly basis, so stay tuned.

ETHDenver

The 0x team will be attending ETHDenver, the largest Ethereum hackathon in the USA. Feel free to come up to us for a chat, we would love to meet you and hear all of your great ideas. If you plan on participating in the hackathon and would like to use 0x in some form, remember to check out our 0x.js Starter Project, our 0x Connect Starter Project and the 0x Wiki. Look forward to seeing you there!

Updated Testnet Faucets

Starting the development journey requires a little bankroll of test ETH and ZRX from a faucet, previously our faucets only supported Kovan, we now also support Rinkeby and Ropsten! But wait there’s more! We have also added support for 0x signed orders, so now you can trade ETH for ZRX using 0x with our faucet. To see the faucet, head over to the 0x Portal while connected to a test network.

New Standard Relayer Endpoints

Maintaining compatible and compliant standard relayer endpoints is important to our goal of shared liquidity and for users of 0x Connect. Amadeus and OpenRelay have been hard at work implementing the standard relayer API and are compatible with the latest version of 0x connect!

New Office Painting

This is just a small shout out to ZRX hodler Mitch Bierer who bumped into us on the street and gifted us a great piece of artwork. Thanks Mitch, it’s hanging proudly in our office.
