Uniswap v4 hooks now pull in outside liquidity, turning the protocol into an aggregator
DeFi & Yields ·
A new "Aggregator Hooks" feature folds external liquidity sources directly into Uniswap v4 pools while preserving UNI fee burns, and it is already live on three networks.
Uniswap confirmed the feature went live on Ethereum, Base, and Robinhood Chain, built into both the Uniswap Web App and the Uniswap API, according to theblock.co. The mechanism works by embedding aggregator-style routing logic inside a v4 hook, letting trades tap liquidity sitting outside Uniswap's own pools while still running through the protocol's standard hook infrastructure.
The design keeps Uniswap's own liquidity untouched on pricing: trades filled from native Uniswap pools carry zero added margin, since that liquidity is described as by far the largest source of onchain liquidity. Only routes that reach into external liquidity sources incur a fee, set at just a couple basis points, which goes toward UNI protocol fees and continues to fund UNI burns. Combined with UniswapX, this routing setup is framed as making Uniswap's api and apps far and away the best aggregators on the market.
Separate coverage of the rollout describes the hooks as wrapping outside liquidity sources from platforms such as Curve and PancakeSwap and converting them into Uniswap pools, per defiprime.com. That framing lines up with the core claim that Aggregator Hooks let external liquidity be absorbed into Uniswap's own pool structure rather than routed around it, with automatic access through the existing web app. The cluster has drawn coverage from five distinct sources, with additional posts, including one tracked at x.com, echoing the same launch across Ethereum, Base, and Robinhood Chain and tying the mechanism to protocol-fee-driven UNI burns.
What remains unspecified is the exact fee schedule beyond the "couple basis points" figure, how routing decisions choose between native and external liquidity in practice, and whether additional external liquidity sources or chains will be added beyond the three networks named at launch. How much trading volume shifts toward externally sourced liquidity, and how that affects the pace of UNI burns, has not yet been reported.
