How Hooks Grow DeFi
summary
Uniswap v4 adds hooks that run custom logic before and after swaps, letting pools implement time-weighted average market makers, dynamic fees, and on-chain limit orders on-chain. One hook attaches to a pool but a single hook contract can serve many pools. Flash accounting and the singleton contract let multi-hop swaps execute inside one transaction. Uniswap reports ~$3 trillion all‑time volume and ~$4 billion TVL; templates, a hook incubator, grants and courses support builders.
