Uniswap v4 Launch

Uniswap Labs has officially released version 4 of the Uniswap protocol, transforming it into a developer platform.

Uniswap v4 is now operational on multiple blockchain networks including Ethereum, Arbitrum, OP Mainnet, and Base, as stated in a recent blog post. Users can provide liquidity on v4 via the Uniswap web app, with swapping functionality being gradually launched across web and wallet platforms.

Key Features

The introduction of “hooks” is a significant change in the protocol, allowing developers to customize interactions within pools, swaps, fees, and liquidity provider (LP) positions. This could foster new features, enhancing liquidity and facilitating more swaps.

Uniswap v4 builds upon the capital efficiency of Uniswap v3 with several architectural improvements. One major change is the adoption of a singleton liquidity architecture, which consolidates liquidity through a single smart contract. This aims to result in faster transactions, reduced gas fees, and an improved user experience.

With this release, liquidity providers are encouraged to migrate their liquidity to the new version or establish new positions that utilize hooks. For swappers, v4 routing will be integrated into Uniswap products in the upcoming days, facilitating automatic routing through liquidity pools across UniswapX, v2, v3, and v4.

Security Measures

Uniswap v4 has undergone nine audits and a security competition, alongside a $15.5 million bug bounty program, and has reported zero critical vulnerabilities.

Last week, Uniswap Labs mentioned that the rollout of V4 commenced that week and will be finalized shortly. The original plan was to release Uniswap v4 in 2024; however, it was delayed due to extensive code audits and security assessments.
