Uniswap v4 Exoloring New Possibilities
summary
Uniswap v4 replaces many per-pool contracts with a singleton pool contract plus flash accounting, claiming gas drops shown from ~$60 to ~$4; it adds a continuous fee spectrum and one external Hooks contract per pool (14 callback functions) that can run before/after swaps, adds/removes, fee updates, donations and more. The Foundry Hook Template deploys mock tokens, initializes a v4 pool, toggles specific callbacks, runs tests that increment counters, and performs a successful swap on a local fork.
