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.
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.
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.
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
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.
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.
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.
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.
