Uniswap Labs has introduced aggregator hooks for its v4 protocol, enabling trades to be routed through liquidity on external platforms. This feature is currently available on Ethereum, Base, and the Robinhood Chain.
Supported external liquidity sources include Curve, Fluid, PancakeSwap V3, Slipstream, and forks of Uniswap V2 and V3. The documentation confirms these hooks are production-ready as of late October 2026.
Hooks are smart contracts that modify pool behavior. Aggregator hooks join existing tools like Permissioned Pools and Dynamic Fee Hooks. Currently, the aggregation layer is developed by Uniswap Labs.
The Robinhood Chain, which launched in July 2026, is a key venue for this rollout, having previously accounted for over 50% of certain Uniswap volume metrics and showing high hook adoption.
