Uniswap v4 has officially launched across multiple blockchain networks, with swapping features expected to be available for all users in the coming days.
Uniswap Labs has announced that its fourth-generation protocol is now open for public access. This major upgrade brings enhanced developer operability and improved on-chain liquidity to the decentralized exchange.
As of January 31, Uniswap v4 is live on Ethereum, Polygon, Arbitrum, OP Mainnet, Base, BNB Chain, Blast, World Chain, Avalanche, and Zora Network.
The rollout of v4 had been initially planned for last year, but was delayed due to comprehensive code audits and multiple hackathons set to stress test the protocol’s system. Uniswap’s team conducted nine audits of v4’s code and issued a $15.5 million bug bounty to address potential architectural issues.
Among the most significant enhancements in Uniswap v4 are the introduction of “hooks” and a singleton liquidity design. Hooks have generated considerable interest, as they aim to transform Uniswap into a more developer-centric decentralized application.
These Hooks are blockchain contracts designed to allow for custom architecture in liquidity pools, on-chain swaps, and crypto fee structures. They integrate seamlessly with the singleton liquidity framework, which combines Uniswap liquidity into a single smart contract.
According to Uniswap engineers, this new liquidity architecture is expected to facilitate cheaper transactions and faster swaps, significantly enriching the user experience.
With over 150 hooks already developed, features range from dynamic fees to automated liquidity management, enabling developers to innovate and enhance integrations more rapidly.
