Uniswap Labs announced that Aggregator Hooks are now live on Ethereum, Base, and Robinhood Chain, bringing liquidity from external platforms into Uniswap v4 and helping users find better trading routes. Fluid, Curve, and PancakeSwap are the first external liquidity sources to integrate. The feature is available through the Uniswap web app and API, with support for more blockchains planned in the future. Aggregator Hooks are built on Uniswap v4’s Hooks feature, wrapping liquidity from external platforms into Uniswap v4 liquidity pools. Uniswap then compares prices on its own platform and external platforms to select the optimal route. (TheBlock)
