Uniswap Labs launches Aggregator Hooks to integrate external DEX liquidity.

Uniswap Labs has launched Aggregator Hooks, integrating external DEX quotes into the v4 routing systems of the Ethereum mainnet, Base, and Robinhood Chain. This feature wraps external sources as v4 hooks, allowing the routing engine to compare quotes and construct transaction routes that include both Uniswap and external venues, with exchanges settled within a single transaction. Exchanges routed via Aggregator Hooks generate protocol fees that support UNI token burning. Developers can integrate new routes through the Uniswap API, and regular users will see external liquidity incorporated into eligible exchanges.
