Uniswap Labs has deployed aggregator hooks that allow Uniswap v4 pools to route trades to liquidity on external platforms. The feature is live on Ethereum, Base and Robinhood Chain and supports Curve, Fluid, PancakeSwap V3, Slipstream, as well as Uniswap V2 and V3 forks. Developer documentation describes it as production-ready as of late October 2026, although there was no formal launch announcement and no third-party aggregator hooks are listed. Access to more pools could reduce slippage on large transactions, while Robinhood Chain, which has sometimes accounted for more than 50% of certain Uniswap volume metrics, serves as a natural testing ground. The rollout moves part of the independent aggregators’ role to the protocol layer but adds technical dependencies on the external platforms being used.
