Uniswap v4 Aggregation Feature Goes Live, Aggregator Hooks Can Wrap External Liquidity as v4 Pools

Odaily reports that Uniswap Labs has announced the launch of Aggregator Hooks, bringing aggregation capabilities to Uniswap v4. The mechanism uses Hooks to wrap external liquidity sources as v4 pools and is now live on the Uniswap web app and API, covering Ethereum mainnet, Base, and Robinhood Chain. On the first day, it supports 7 external sources including Curve, Fluid, and PancakeSwap, with more networks to be added gradually. Per-block routing will fetch the latest quotes from integrated sources, build the optimal path between Uniswap pools and external sources, and settle within a single transaction without requiring new approvals; the related swaps will incur a protocol fee, which will be used for UNI burning.
