Uniswap Launches Unichain, DeFi-Focused Layer 2 on Optimism Stack

Oct 10, 2024, 01:33 PM

Uniswap, a leading decentralized finance (DeFi) platform, has announced the launch of Unichain, a new Ethereum Layer 2 (L2) blockchain designed to enhance DeFi capabilities in a multichain world. Built on the Optimism Stack as an optimistic rollup and integrated into the Superchain—which includes networks like Optimism and Coinbase-incubated Base—Unichain aims to be the home for liquidity across chains. The new L2 offers fast transaction blocks of 250 milliseconds, cross-chain interoperability, and a decentralized validator network. Uniswap founder Hayden Adams described Unichain as "a labor of love based on six years of designing and building in the DeFi space," aiming to make it the best home for DeFi. Uniswap collaborated with Flashbots to optimize Unichain, introducing features such as fast state updates, a framework to internalize miner extractable value (MEV), and an economic finality system for quick settlements. Several projects, including Privy.io, QuickNode (which announced day-one support for the Unichain testnet), AlchemyPlatform, and The Graph, have announced support for Unichain, signaling broad industry collaboration.
