Uniswap v4 Launches on Multiple Blockchains, Boosting Developer Tools and Liquidity

Uniswap Labs has officially released version 4 of its decentralized exchange protocol, Uniswap, across multiple blockchain networks. The upgrade, which has been in development for some time, introduces several improvements aimed at enhancing developer operability and on-chain liquidity.

The new version of Uniswap is now available for public access on Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche, and Zora Network. The release of v4 comes after extensive code audits and multiple hackathons to stress test the protocol's code. The team behind Uniswap also audited the code nine times and issued a $15.5 million bug bounty to address any lingering architecture concerns.

Two of the most significant upgrades in Uniswap v4 are the introduction of "hooks" and the singleton liquidity design. Hooks, in particular, have drawn attention as the upgrade promises to transform Uniswap into a developer-focused decentralized application. The Labs describe hooks as blockchain contracts built to allow custom architecture for liquidity pools, on-chain swaps, and crypto fees. Hooks go hand-in-hand with the singleton liquidity framework, which blends Uniswap liquidity into a single smart contract.

The new liquidity architecture should enable cheaper transactions and faster swaps, improving the end-user experience. Over 150 hooks have already been developed, introducing features such as dynamic fees and automated liquidity management. By allowing developers to build and experiment directly on top of the protocol, hooks enable faster development cycles and stickier integrations.
