Research & Development

Protocol

We created the first Loopring 3.0 DEX for WeDEX which is now live at:

Contract 0x7d3d221a8d8abdd868e8e88811ffaf033e68e108 is the first live DEX leveraging zkRollup for scalability on Ethereum mainnet. Certainly, it is the first one enforcing on-chain data availability.

Through this contract, you can find transactions that are the proven *batches* submitted to Ethereum. Within them, they contain the actual DEX activities: deposits, withdrawals, and trade settlements. Our upcoming open source DEX Browser is needed to discern the actual granular activity.

The stats & capabilities are exciting:

In the near future, we plan to help WeDEX complete the full lifecycle testing, including testing the Shutdown mode (operators proactively shut down the DEX) and Withdrawal mode (operators violate some protocol rules). In all cases, Loopring protocol ensures DEX users are able to withdraw their rightful assets.

On WeDEX, there are currently about 100 users invited for this first round of beta testing, which will last for one week. For this beta, the Shenzhen-based team is focused on serving Chinese language users, but will open their English language side at some point in January. Feel free to follow them on Twitter to stay tuned.

We have also finished the smart contract implementation for Loopring’s smart contract wallet called “Hebao”, 荷包, which means purse in ancient Chinese. Hebao will be a standalone smart contract wallet, with very tight Loopring v3 integration for user onboarding. Next week we will start unit testing the contract. Our goal is to complete unit testing by the end of February. You can read more about Hebao in our recently published 2020 roadmap.
