Uniswap v4 Exploring New Possibilities
summary
Uniswap v4 moves all pools into a singleton architecture with internal token accounting and flash accounting, adds unlimited and dynamic fees, and exposes programmable hooks that can change swap math, fees, routing and access control. The Uniswap hooks library and OpenSeline implementations include order books, liquidity-penalty, anti-sandwich and a rehypothecation hook so LPs can earn external yield. Routing inside the pool cuts gas dramatically (presented as 10x less gas), and examples show stablecoin-stability incentives, dual pricing for memecoins, and MEV-aware fee adjustments.
