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.

The LRC Golden Staking Window Has Closed; Loopring Team Is Now Staking

A few days ago, the ‘Golden Staking Window’ came to a close. This was defined by the Loopring Team staking its own LRC tokens. We released the details and txs in a tweet thread. This post reiterates and expands on the points so it can more easily be referenced in future.

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 and Chainlink Fireside Chat

Last week, Loopring’s Chief Architect, Brecht Devos, sat down to chat with Chainlink’s Johann Eid and Rory Piant in a live video chat. They spoke about ZK Rollups, DEX scaling, and the use of Chainlink oracles to secure a component of LRC staking. The video can be found here.

Loopring Testing Phase 1: Data Recap

On December 18, 2019, we started to work with WeDEX to test the integration of Loopring Protocol v3, the Lightcone relayer, and WeDEX’s front-end on Ethereum mainnet. This is the deep dive data and analysis.

Chainlink and Loopring Collaborate on Oracles for zkRollup DEX Protocol

Chainlink and Loopring are pleased to announce our collaboration across several oracle integrations in Loopring’s v3 zkRollup DEX protocol. The first of which is live on Ethereum mainnet: a faithful LRC/ETH price feed for DEX owners to anchor their LRC economic security staking.

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.

LRC Opens Golden Staking Window

Loopring Foundation is staking its own LRC. We’ve created a “golden staking window” which opens now and will close at the end of January of 2020. This window can be beneficial to LRC holders.

Loopring Deployed Protocol 3.0 on Ethereum

We are thrilled to announce the release of Loopring 3.0-beta4 and its deployment and configuration on Etheruem mainnet. Loopring 3.0-beta4 will be used in production to serve WeDEX.

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.

DEXes Rising: Next Chapter, High Performance Orderbook Exchanges on Ethereum

DEXes on Ethereum have hit their stride. Recent growth has been concentrated in on-chain, curve/ reserve based DEX models. With advances in layer 2 such as zkRollup, the next cycle will see scalable & secure orderbook DEXes take root on Ethereum, allowing for true non-custodial trading, not swapping
