LRC Staking and Claiming Instructions

LRC is the Loopring protocol’s token. It can be staked by holders to earn protocol fees (a percentage of the volume flowing through all Loopring-based DEXes), and is staked by DEX owners as a bond for service-level guarantees. About 10% of the total LRC supply is currently staked.

Loopring Monthly Update — 2020/01

Welcome to the first Loopring Monthly Update! Of course, if this isn’t your first time reading a Loopring update, you know we’ve been doing Bi-Weekly updates for years. But with protocol maturity, we are slowing down to half-speed on updates.

Composability between Ethereum Layer 1 and 2

Onchain composability with layer 2 solutions poses some challenges. Doing things offchain is great for scalability, but how do you connect onchain interactions with offchain logic? We want our ZK Rollup exchanges to be part of the composable Ethereum ecosystem.

Loopring 2020 Development Roadmap

As each year draws to a close, Loopring releases the R&D roadmap for the coming year. This supports transparency and allows the community to obtain a greater understanding of the plan. Equally important, it forces us to think hard about the future and to reach consensus on the plan.

We Take 'The Ultimate Non-Custodial Test'

Our foremost duty is towards user sovereignty & security — ensuring that Loopring-based DEXes can never access user funds, nor prevent users from accessing their own funds. Even if Loopring (the team, the foundation, anything) shut down or became malicious, it would not matter.

Loopring Bi-Weekly Update — 12/01/2019

The last two weeks have been super exciting for us: Loopring 3.0 beta4 will finally complete deployment early next week. Loopring will be Ethereum’s first zkRollup DEX protocol enforcing on-chain data availability. We are ready to roll!
