Our Vision for Uniswap v4

Hayden Adams introduced the vision for Uniswap v4 and released its draft code for public building and feedback, which he expects to take months. The central idea is "hooks," contracts that run at points in a pool's lifecycle, letting pool creators choose tradeoffs that v3 fixed or add features such as dynamic fees, onchain limit orders and time-weighted average market making. Uniswap v4 also places all pools in one singleton contract and uses flash accounting, with early estimates showing a 99% reduction in pool creation gas costs. The code will be released under a Business Source License 1.1 that converts to GPL after four years.
