Uniswap Labs Launches Layer 2 Unichain for Faster DeFi Transactions
Designed specifically for DeFi, Ethereum Layer 2 Unichain is intended to be a liquidity hub across multiple blockchain networks. Uniswap Labs expects the platform to improve the user experience while also generating revenue through network fees, with approximately 20% of earnings directed to the company.
Unichain has undergone testing since October 2024 and is classified as a Stage 1 rollup. At this stage, it incorporates some decentralized features but retains central oversight for security.
One key innovation expected in the coming months is Rollup-Boost, a block-building system developed in collaboration with Flashbots. The system will divide Unichain blocks into four smaller sub-blocks, each processed in 250 milliseconds.
Unichain Joins Optimism’s Expanding Superchain Ecosystem
Although not available at launch, Rollup-Boost is designed to enable sub-second block times, further enhancing transaction efficiency. Initially, Unichain will operate with block times of 1-2 seconds, similar to Kraken’s Optimism-based chain, Ink.
Unichain joins the growing ecosystem of OP Stack-based Layer 2 networks, which includes Coinbase’s Base, Kraken’s Ink, and Sony’s Soneium. With its mainnet now live, Uniswap Labs has become a core contributor to Optimism’s Superchain initiative.
