Uniswap Labs has launched Unichain Mainnet, a decentralized blockchain designed to reduce transaction costs and accelerate decentralized finance (defi) operations.
Decentralized Rollup Unichain Goes Live, Targets Defi Scalability
The Ethereum layer two (L2) network, tested through 95 million transactions and 14.7 million smart contracts in four months, aims to enhance defi accessibility with 1-second block times and gas fees approximately 95% lower than Ethereum’s base layer. It operates as a Stage 1 rollup, featuring permissionless fault proofs, with plans to expand decentralization through its Unichain Validation Network (UVN).
According to the announcement, early 100 crypto platforms, including Uniswap, Coinbase, and Lido, are building on Unichain, with many applications live at launch. Developers can deploy apps, create custom logic via Uniswap v4 hooks, and integrate stablecoins like USDC. The chain also supports ERC7683, a cross-chain transaction standard, and will enable native interoperability via the Superchain later this year.
For users, Unichain allows asset bridging through wallets or platforms like Coinbase, token launches via dedicated tools, and liquidity provisioning through Uniswap’s v2, v3, and v4 interfaces. Future upgrades include trusted execution environment (TEE)-based block production to reduce block times to 250 milliseconds and mitigate miner-extractable value (MEV).
Unichain’s roadmap emphasizes scalability and security, with UVN nodes enabling community-driven validation. The network’s integration with Ethereum Virtual Machine (EVM) ecosystems positions it as a hub for cross-chain DeFi activity, aiming to streamline transactions across decentralized applications.
