Uniswap Labs officially releases Uniswap v4, introducing new features and improvements

Uniswap Labs has officially released Uniswap v4, bringing significant upgrades to its decentralized exchange protocol. The new version is now live on multiple blockchain networks, including Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche, and Zora Network, as of January 31, 2025.

The launch follows delays from last year, caused by rigorous code audits, extensive testing through hackathons, and a thorough review process that included nine audits and a $15.5 million bug bounty program to ensure security.

Key features in Uniswap v4 include the introduction of “hooks” and a singleton liquidity design. The “hooks” feature allows for custom liquidity pool architectures, on-chain swaps, and adjustable fees, making it a game-changer for developers building decentralized applications (dApps). Meanwhile, the singleton liquidity framework integrates all liquidity into a single smart contract, helping reduce transaction costs and improve the speed of swaps, thus enhancing the overall user experience.

Uniswap Labs emphasized that these updates are aimed at improving developer operability and the flexibility of liquidity management on the platform. Over 150 hooks have already been developed, enabling innovations like dynamic fees and automated liquidity adjustments. By offering developers the ability to directly build and experiment on the protocol, Uniswap v4 encourages faster development cycles and more robust integrations.

This launch positions Uniswap v4 as a more developer-friendly platform, helping to streamline the creation of decentralized applications and enhance liquidity management across the decentralized finance (DeFi) ecosystem.
