Unichain
A DeFi-focused L2 built by Uniswap, with 1-second blocks and verifiable block building.
Unichain is the L2 opened in February 2025 by Uniswap Labs, the team behind the Uniswap exchange. Tuned for DeFi trading, it uses 1-second blocks and adds even faster pre-confirmations.
It promotes verifiable block building, which lets others check that blocks were built by the rules. Fees are paid in ETH; in this city the UNI token also counts toward the district’s weather.
On standard blockchains, latency between blocks creates arbitrage windows and MEV extraction that erode returns for liquidity providers. Unichain addresses this by cutting block times to one second and introducing 250-millisecond sub-blocks (Flashblocks), bringing decentralized exchange execution closer to centralized exchange responsiveness.
By combining Trusted Execution Environments (TEEs) for verifiable block building with transparent priority-fee ordering rules, Unichain structurally reduces predatory sandwich attacks and front-running—delivering fairer execution prices for swappers and better yield retention for liquidity providers.
