The Uniswap Foundation has announced the tentative launch date for Uniswap v4 in Q3 2024, following the upcoming Dencun upgrade on Ethereum. Currently in the "Code Freeze" phase, the foundation is focusing on core code completion, testing, and security enhancements. After this, audit firms and a community audit contest will be used to check v4's code, aiming to make it the "most rigorously audited code ever deployed on Ethereum." The launch date is subject to change depending on the status of the Dencun upgrade, which introduces Ethereum Improvement Proposals aimed at reducing layer 2 transaction fees.
