What is Unichain?
Unichain is a Layer 2 blockchain based on the OP Stack, developed by Uniswap Labs with the vision of becoming the “home of decentralized finance (DeFi).” Launched in February 2025 after four months of intensive testing (handling over 50 million transactions on the Sepolia testnet), the network offers fees up to 95% lower than Ethereum L1, one-second block times, and native cross-chain interoperability. This solution addresses multi-chain fragmentation and substantially improves user experience (UX) in DeFi through technologies like Rollup-Boost (with 250ms Flashblocks), a “fair priority” anti-MEV system, and Permissionless Fault Proofs. Innovations include the upcoming Unichain Validation Network (UVN), designed to allow open, permissionless validator execution. The protocol is estimated to generate roughly $500 million in annual revenue for Uniswap Labs and UNI token holders through fee optimization.Useful Links
