Conversations exploring the latest Uniswap V4 protocols, hooks and industry news.
One prompt to Fable 5.0 with Claude. One follow-up for mobile. The result is swapboy.xyz - a Pokémon Blue-flavoured frontend for the Uniswap API with working MIDI audio, pixel art, character dialogue, top-5 pool integration, and a real on-chain swap path. A short post on what this says about the state of agentic development against the Uniswap API.
Hooks turn Uniswap V4 from a protocol into a platform. There are 14 of them - but four are doing most of the interesting work. What each hook does, when it fires, and why the return-delta hooks deserve their own conversation.
Static liquidity is leaving money on the table. This piece is a deep-dive cookbook for hooks that actively manage liquidity - JIT positioning, rehypothecation to AAVE, and auto-rebalancing - with token flow diagrams, real Solidity, and an honest accounting of where each pattern can hurt you.
If your hook uses beforeSwapReturnDelta or afterSwapReturnDelta, the standard Uniswap V4 events are either missing or lying - and every indexer, dashboard, and LP tool in the ecosystem is reading those events. The fix is four small events, and this post shows where each one goes.
Uniswap shipped a Trading API that handles routing, quoting, and Permit2 across V2, V3, V4 and UniswapX. It's also the cleanest example of AI-first developer relations in DeFi right now. A tour of what it does, how a swap flow looks in real code, and why every doc page now has an 'Open in LLM' button.
Uniswap V4's biggest architectural shift is invisible to swappers but underwrites everything else - flash accounting, ETH-native pools, hooks, and far cheaper pool creation. What changed, and what it unlocks.
Concentrated liquidity rests on one foundational idea: the tick. Once ticks click, the rest of Uniswap V4 follows - sqrtPriceX96, tick spacing, swap mechanics, and the gas tricks that make the whole thing fast.
