Uniswap Labs officially releases version 4
Uniswap Labs has launched version 4 of the Uniswap protocol, transforming it into a developer platform. This new version operates on several blockchain networks, including Ethereum, Arbitrum, OP Mainnet, and Base. Users can now provide liquidity through the Uniswap web app, with swapping features being gradually introduced across various platforms.
Uniswap v4 introduces “hooks,” which are contracts that allow developers to customize how pools, swaps, fees, and liquidity provider positions work. These hooks enable new features that could enhance liquidity and increase the number of swaps. The protocol also improves on the capital efficiency of Uniswap V3 with several architectural upgrades.
One significant change is the “singleton” liquidity architecture. This consolidates liquidity into a single smart contract, aiming to speed up transactions, reduce gas fees, and enhance the overall user experience. Liquidity providers are encouraged to move their liquidity to v4 or create new positions that utilize the hooks feature.
In the coming days, the routing for swaps in v4 will be integrated into Uniswap products. This means that swaps will automatically route through liquidity pools across UniswapX, v2, v3, and v4.
Before the launch, Uniswap v4 underwent nine audits, a security competition, and a bug bounty program with a budget of $15.5 million. These efforts resulted in no critical vulnerabilities being found.
