We have made excellent progress in our distributed version of the relayer backend system and the Circulr wallet.



On Ethereum: We have completed refactoring all the protocol tests. Now they are either configured with structured order data or with raw transaction/ring data. The latter also a much easier way to figure out why some ring transitions failed in production. We have also improved test coverage with more tests.

The Loopring protocol’s JavaScript reference implementation — which is being used by our testing framework — will become a standalone project. It will also be available as a web-based ring-matching simulation tool for wallet and DEX developers.

On NEO: We followed up on the Storage Injection bug on NEO smart contracts, and have verified that LRN token’s smart contract has not been affected and is secure.


We have completed the coding of the distributed version of our relay system. This distributed version, referred to as the Relay Cluster, is an excellent optimization in system architecture with faster socket data streaming, better responsiveness, and no single point of failure. During the next couple of weeks, we will focus on testing the various components of the Relay Cluster.

The Relay Cluster has many RPC services, and some of these RPC services have become standalone git repositories such as miner, extractor, etc. A robust, high-performance and production-ready Relay Cluster will take even more development, testing, and documentation.


We pushed over 400 git commits to the there web frontend related projects: loopring.js, Loopr, and Circulr.

Loopring.js: recently we have accomplished the following:

  1. Provided a new way to perform ABI encoding and support of decoding of transaction inputs and outputs.
  2. Added support to MetaMask, TREZOR, and Ledger.
  3. Added support to WebSocket;
  4. Added very basic documentation.

Web-based Wallet (Loopr & Circulr): We have also made significant progress on both wallets. We’ll skip the details here and let our community know once we launched new versions.

iOS Wallet App: We have made more progress in iOS app, including the following features/functionalities:

  1. Submitting and canceling orders;
  2. Optimizing the gas price when sending tokens;
  3. Using GethBigInt to handle integer overflow;
  4. Supporting the zoom mode, which requires a lot of UI layout updates;
  5. Order book in the market detail view;
  6. Updating many UI components, such as circle chart, numeric keyboard, text field validation and so on.

We have also decided to focus on app development starting from Q3 and put web-wallets as the secondary priorities.

New Website

We’ve also launched a new website, and the developer portal is under construction and will be available soon.
