Updates on Loopring Protocol and its ecosystem every 2 weeks.

Loopring Bi-Weekly Update — 11/24/2018

With protocol 2 complete and undergoing audits, our attention has also turned towards protocol 2.1, with security token support taking shape. Frontend web and mobile products have been refined and released — lots of new features. Lightcone Relay backend testing is in full swing.

Protocol

We have continued making small improvements to protocol 2 to make it ready for release. EIP712 signature support was tested in MetaMask to ensure compatibility with third-party libraries.

Excitingly, we have also finished adding ERC1400 security token supportplanned for release in protocol 2.1 once the ERC1400 standard is finalized. The protocol team is already looking ahead and is researching the possibilities for the next big protocol release.

Relay

Lightcone (Relay 2.0)

Lightcone Relay has been moved into the software testing phase. We have completed software architecture refactoring in a new development cycle. Based on this software architecture, we have implemented actor models and related tests that are parts of core features. In addition, we have started implementing the interface to protocol 2.0 in Lightcore Relay. We also have implemented a new version of market cap API as the CoinMarketCap API will expire in December. The latest API will support Relay 1.0 and 2.0 to provide latest information for global cryptocurrency market.

Frontend & Product

iOS Wallet

iOS development has recently been focusing on compatibility, especially on P2P order compatibility. Users can scan QR codes to complete P2P orders between Circulr DEX, Android and iOS. We have also resolved compatibility issues between iOS app and the latest iOS 12. We have fixed a compatibility issue where importing imToken wallet’s mnemonics generate different addresses. We have improved WeChat login, account binding and WeChat logout. We have implemented upgrading the latest iOS app inside the app. Users don’t need to navigate to the website to download the latest iOS app anymore. We also have updated the UI for transaction fee of sending ETH.

Android Wallet

In the past two weeks, we have implemented login authorization in Circulr DEX where users can just scan QR codes on Circulr DEX to authorize address login, which is very convenient to use in Android app and website. We have also implemented scanning QR codes to enable tokens, submit orders, and cancel orders. These features will allow a better user experience between Android app and Circulr DEX and will be available in the next release.

We have implemented ETH and WETH conversion in the trading view using native development. We have fixed a compatibility issue where importing imToken wallet’s mnemonics generates different addresses.

We have implemented notifications for upgrading Android app. When a new version is released, Android app will pop up a notification where users can choose to upgrade with a single click.

We have been improving the security based on the audit report from SECBIT. We have implemented prohibiting users from taking screenshots of mnemonics, keystores, or private keys. We have implemented strong password checker.

For UI, we have implemented app launch animation, optimized the UI layout of notifications and updated the instructions in English and other languages. In addition, we have implemented traditional Chinese support, set the default language to English, updated the UI when creating a wallet and updated the UI for transaction fee of sending ETH.

imToken & H5DEX

We are going to release a new version of imToken DEX which supports many new features.

First of all, imToken DEX will now support P2P trade. When it’s released, imToken iOS app and Android app can participate in the airdrop, submit a P2P order and complete an order.

Secondly, imToken DEX supports scanning to trade. It will be available on both imToken iOS app and Android app. imToken users can use the scan feature for all kinds of trading, including login, submit orders, cancel orders, convert ETH and WETH, enable tokens and complete a P2P oder.

Finally, and one of the most important features is that above features are available in imToken homepage. Users don’t need to enter the dapp. To use all trading features, users just need to click the scan icon in the imToken homepage. Of course, imToken also provides many features besides these critical features.

It makes it much easier for users to enjoy Loopring decentralized trading. The current user experience will be closer to Alipay and WeChat. imToken DEX is currently in private beta testing, and we will release it to beta users next week. You can learn more from the following videos:

1.Scan to login: click

2.Scan to submit order: click

Circulr DEX

Circulr DEX is a decentralized exchange developed by UP Blockchain and Looping. Here is a post with video tutorials on how to use Circulr.

Circulr DEX has completed many features. We have added market price information in P2P submitting form for users to reference. We have implemented token balance, order amount, enabling token and other information to make it easier to submit an order. We also have implemented the order detail page where users can review all order based on the transaction id. Beside these new features, we have fixed many bugs, such as Ledger login, order valid time setting and others.

Android DEX

Android DEX is a web DEX inside Loopring Android Wallet. It supports market and P2P trading. For this airdrop, we have continued Android DEX development.

First, we have added market price information in P2P submitting, token balance, order amount, enabling token and other informations. We have also improved the user experience of P2P trading, including displaying fill rate and order amount. We have improved the verification when completing a P2P order. We also have unified error messages and error codes across wallets.

Loopring.js

We have released Loopring.js 2.0.12. The new version has implemented P2P APIs and bugs fix.

UI/UX

Our designers have been working on product design and UI with the engineering team. Two main areas are:

Loopring Bi-Weekly Update — 11/10/2018

Protocol

We have successfully completed smart contact development for protocol2 and protocol2-js and we are continuing to test and improve the code. 
Meanwhile, our second bug and optimization bounty program is underway.
Our dev team has also started to develop loopring smart contracts 2.1. This will begin to incorporate a focus on security tokens and the ERC1400 standard. We have also teamed up with the Dora.network team to start developing a sidechain solution to allow for high performance, DEX specific transactions with ultimate settlement to Ethereum.

Relay

Relay 1.0

We have been maintaining Relay 1.0 to make sure that all functionalities work in the new version of wallets, especially P2P orders. We also have removed some inactive tokens from the Relay’s hosted orderbooks.

Lightcone (Relay 2.0)

In the past two weeks, we have completed the core feature of the new order matching mechanism and refactored the order size management. This will improve the orderbook and make order matching more efficient. The new version of Socketio and JSON RPC APIs have been moved to the verification stage, including fetching transaction data and trading history data from CoinMarketCap and MyToken. We have also implemented unit tests for these APIs. In the next step, we will integrate all components in Lightcone Relay and start integration tests.

Frontend & Product

iOS Wallet

We have updated P2P trading in iOS app for the third LRN airdrop (please note we have slightly pushed back/expanded the airdrop date to ensure everything works perfectly and anyone who’d like to, can participate). As the P2P trading API has been updated, QR codes generated in 0.9.15 and earlier version won’t be compatible to Android app or 0.9.16 version. Please update your UP Wallet apps. Another important new feature is WeChat third party authorization. We have redesigned wallet list views, wallet address view and P2P QR code view. We have reduced the size of app by 50% successfully. We have fixed a crash when pressing “0” button in P2P trade view. We have implemented automatically detecting ETH address in the pasteboard: If there is a valid ETH address copied, the app will ask users whether they want to send tokens to that address (pretty neat! :).

Android Wallet

The main new feature in Android app is WeChat third party authorization. It remembers users’ settings configuration. It will make it easier for users to use across platforms. Another main feature is that users will be awarded 20% of all future trading fees from users they refer. We have implemented sharing P2P trade in Android app so that users can share a QR code of P2P trade to friends. We have fixed some crashes in the last release version. We have fixed a UI bug where pending transactions of ERC20 tokens may disappear. We have fixed currency and language settings that were not restored when the app relaunches. We have fixed that the password can’t contain special characters. We have implemented notifications for importing the same address.

H5DEX

After H5DEX completed support for the Android app, we have been improving the P2P trade feature. We have improved displaying the price of P2P trade by adding sell price and buy price. It should make it easier for users to calculate prices and costs. Besides, we have implemented sharing P2P trade in Android app. We have improved ETH conversion and fixed all related issues. At the same time, we have also improved P2P trade notifications.

UP DEX / Circulr DEX

UP DEX is a decentralized exchange developed by UP Blockchain and Loopring. To support the third airdrop, we have released the alpha version of Circulr V2 — UP DEX for PC web. Circulr V2 has a lot of new features:

  1. Supports Kline and volume chart.

  2. Supports P2P trading where users create a P2P order that can be scanned by Android and iOS apps.

  3. Supports market trade and P2P trade in browser wallets, hardware wallets and other wallets.

  4. Supports trade in UP Wallet iOS app.

  5. Supports grey, white, purple and blue color themes with one click switch.

  6. Supports four columns, three columns with large views, and three columns with small views.

  7. Supports a message center and push notifications.

  8. Improves the whole UI style and user experiences in a short period.

You can try Circulr DEX at https://circulr.loopring.io

We also released UP DEX macOS app. The macOS app has the same functionalities as Circulr Web but is more stable and has better performance. More importantly, it can run on any computer without worrying about different versions of browsers, which provides constant user experiences.

Loopring.js SDK

We have released Loopring.js 2.0.9. The new version has implemented notifyScanLogin and notifyCircular APIs. This will provide a better user experience when users use wallets to scan order in the web.

Loopring Bi-Weekly Update — 10/27/2018

We’ve made some great progress in the past two weeks. The Android UP Wallet 1.0 Beta is now available to download at Google Play. We released information for the third LRN airdrop.

Protocol

We continued testing and optimizing protocol 2.0 while working with SecBit to audit the source code. We also made a small change to the fee model. It used to be possible to pay the matching fee in the token that got bought when the owner did not have a sufficient balance in the fee token, but now the matching fee always needs to be paid in the given fee token. The order fill amount is downscaled if needed.

We also finished designing the Loopring protocol smart contract 2.0 bug bounty program. Millions of LRC will be rewarded to bounty hunters and optimizers— exact details will be released in the next few days.

Meanwhile, we have also started designing and development of Loopring Protocol 3.0. We are thinking of creating a sidechain on Ethereum to do settlement and clearing for small transaction amounts. This solution can solve low Ethereum TPS and network clogging problems. Loopring has collaborated with the Dora.Network team to develop this solution. Testnet is expected to be delivered at the end of the year.

Relay

Relay 1.0

We have updated all features in order to support the Android app and we will continue testing it until the third LRN airdrop begins. (more on this below)

Lightcone Relay

We have redesigned the Lightcone relay (relay 2.0) core orderbook and matching algorithm in order to build better a matching mechanism for Loopring Protocol 2.0. We have finished lightcone-core and lightcone-actors and are now running the testing, completed Socketio and Jsonrpc core codebase, and will adjust them according to future use.

We have introduced trading data from top exchanges and crypto market websites, like MyToken.io and CoinMarketCap, to provide more precise price and volume to our traders.

Frontend & Product

Ring Tracker

Loopring frontend’s team have finished a new UI/UX for RingTracker which we will release in the near future.

Loopring Bi-Weekly Update — 10/13/2018

We skipped our last update because we were at our company offsite. In the past four weeks, our team has completed Loopring Protocol 2.0, updated our relays and interfaces, successfully held a LoopringDEX Trading Competition and sponsored two Hackathons (CryptoBazar and ETHSanFrancisco).

Protocol

Loopring Protocol 2.0 code has been completed. Check here for a brief overview of features. Code optimization is nearly finished and has greatly reduced gas usage. We also changed the format of the data we send to the smart contract to settle rings to reduce its size. The new format now allows us to more easily add data for new functionality while maintaining backward compatibility.

Loopring Protocol 2.0 smart contract will support EIP 712, a scheme to encode data and structure to allow meaningful messages to be displayed to users for verification when signing.

We have passed stress tests for matching ten orders in a single order-ring.

We have signed a contract with a professional third party security firm to audit and review our 2.0 code. The results will be delivered before Dec 15, 2018.

Relay

Relay 1.0

We have fixed several ticker bugs and revised and checked relay database table and index. Meanwhile we were optimizing ring-tracker data and order matching depth. Our relay 1.0’s focus is now to develop the module for marketcap and functionality.

Lightcone Relay

This LoopringDEX Trading Competition has taught us that we must create a more user-friendly orderbook module. We have decided to redesign the orderbook module, and is one of Lightcone relay’s core improvements. We believe the new module will significantly improve matching efficiency.

Frontend & Product

Ring Tracker

We launched RingTracker, a tool to help visualize the activity on the Loopring network. Activity is still limited as we are a few months away from professional market makers accessing the ecosystem, but there was a large spike last week due to the trading competition. A new and improved RingTracker update is still ongoing.

iOS App

In the past four weeks, we have released four updates for Loopring partner wallex Up Wallet to improve user experience We also sourced the price data from Coinmarketcap. User now choose referral price in P2P order.

Korean language has been added into iOS app.

Android App

Android codebase is almost finished and the app functions very well. We have made a few more improvements, including UI/UX testing, token customisation, QR scan etc…

UP Wallet iOS in Korean, and Android 1.0 in Chinese

Looping.js SDK

Loopring.js V2.0.0 has been released, and we simplified the API integration procedure for wallet developers. Reorganized loopring.js developer library. Now developers can very easily customize their Wallex or DEX according to their needs.

H5DEX

H5DEX V2.0 is about to be released and open sourced. H5DEX V2.0 has added brand new Loopring-themed colour UI and clearer market depth graphs and and line charts. iOS and Android APIs have also been optimized.

Loopring Bi-Weekly Update — 09/15/2018

Apologies for the delay on sending this out. The update came out on the 15th, but for those of you who might’ve missed it, here you go!

We have just launched a new blog for our Chinese communities: https://blogs.loopring.org considering our WeChat public account got banned last week due to “violations” of using terms such as ICO, token economy, etc.

We will also skip the next bi-weekly report as we have scheduled an offsite during that weekend. All updates will be incorporated in a later biweekly report.

Protocol

We fine-tuned the design of the Loopring Protocol 2.0 and improved the fee model, fee burning mechanism, and burn rate rank mechanism. The corresponding code was updated, and the tests were enhanced.

We re-discussed and agreed that it is no longer necessary to register ERC20 tokens at the protocol level to enable them for trading. So we decided to yield the token listing decision making power to relays completely. Protocol 2.0 will unconditionally support all ERC20 tokens for trading. We have updated corresponding code and unit tests. In the near future, relays and wallets will have all and absolute power to make business decisions regarding token listing and adding more trading pairs, which will give Loopring 2.0 a more decentralized nature.

The EIP712 support has been partially submitted to the EIP712 branch and is expected to be finalized and tested next week. Supporting EIP712 by showing structured data to users before signing will improve trading security and user experience.

We developed a simple voting smart contract based on user’s LRC balance (other types of data, such as age, will also be used in the future for calculating voting weights). This work is a small step towards decentralized governance. The code is now part of the master branch.

We also improved the smart contract simulator protocol2-js to log more details about each micropayment of each settlement transaction.

As of now the two Protocol 2.0 key repositories, protocol2 and protocol2-js, are still close sourced. We will get ready and open source them in about two weeks.

Relay

Relay 1.0

We added an API to get the price from CoinMarketCap which is now pushed online. Relay 1.0 also added support to hide trading pairs with low volumes, and display certain trading pairs according to custom configuration in the relay. We are now working on different levels of order aggregation in order books.

Lightcone Relay

We wrapped the code for accessing multiple Ethereum nodes into a small library called ethcube. It will monitor each node’s data synchronization status (via eth_syncing) and block height (via eth_blockNumber) for dynamically load balancing. Ethcube will be open-sourced together with the Lightcone relay codebase.

We have also committed more code in several critical modules including order-database, matching, and balance/allowancing cache.

Frontend & Product

Ring Tracker

We finished the integration testing for Ring Tracker and resolved some issues we found. This tool is being used and further tested internally. We will improve the UI in the near future and then migrate it to the new domain: ringtracker.io.

iOS App

We are happy to announce iOS app 0.9.9. You can download this new version on https://upwallet.io. We have redesigned the QR code. You can scan the QR code to transfer token and submit orders, as well as sharing the QR code of wallet address and P2P orders. The new QR code will become your wallet’s new “business card”.

The latest version has improved security. Password protection is now available when backing up mnemonics and exporting private keys. We have implemented hiding app data when switching app in iPhones. In the trading view, we have added a price alert feature to warn users from submitting orders with irrational prices relative to third-party prices. We have unified UI across many views, especially the size of fonts. We have also fixed an issue where the nonce value has not been updated when switching wallets. In the meanwhile, we have improved the user experience when the app is loading data, and have fixed crashes caused by network unavailability.

Android App

For our Android app, we have refactored the original codebase by introducing a better design pattern called MVP which is widely adopted by Android developers. The adjustment of design concept accelerates the rhythm of subsequent development, reduced development cost, and more importantly, improves the performance of the app as a whole. At the same time, we have achieved the following:

  • Finished wallet total fiat value calculation and enabled fiat currency selection in Settings;

  • Finished fetching token’s price in fiat using the backend API;

  • Enabled applying different precision settings for each token based on configurations in the relay.

  • Added a component to refresh UI triggered by drag down views; added ticker component to display price updates.

Looping.js SDK

We optimized the interface and released the V1.0.8 version, and also optimized the library’s documentation which will be released as part of a better version of our Developer Portal.

H5DEX • Circulr DEX • Loopr Wallex

These three web-based products with DEX functionality listed BRM/LRC, BRM/WETH, RTE/LRC, RTE/WETH, MRL/LRC, MRL/WETH, APPC/LRC, APPC/WETH trading pairs. We also optimized the projects’ dependencies on the Loopring.js library and enabled the “price alert” feature.
