UniswapUniswap's Aggregator Hooks are live on Ethereum, Base, and Robinhood Chain in the Uniswap Web App and API, turning Uniswap v4 into an onchain aggregator. Each hook wraps an external liquidity source into a v4 pool the router treats as native liquidity; 7 sources launched, covering more than 90% of DEX activity across the three chains, with more chains and sources coming.
Founder Hayden Adams described the design in the launch thread: "We took the logic of an aggregator and smushed it into a Uniswap v4 hook," letting Uniswap route directly to external liquidity sources. Uniswap had teased the drop the day prior with a 🦄-hinted "New hook drops tomorrow" post on X before revealing the announcement.
