Uniswap Labs activated Aggregator Hooks in its web app and API on Ethereum mainnet, Base and Robinhood Chain, expanding the outside liquidity sources its swap-routing system can use.

Seven external sources were available at launch, representing more than 90% of decentralized-exchange activity on those networks. Aggregator Hooks connects those sources to Uniswap’s v4 routing system.

The router gathers fresh quotes each block and builds routes across connected sources. That lets a swap use liquidity from sources outside Uniswap’s own system as part of its route.

Swaps routed through external sources generate protocol fees that contribute to Uniswap (UNI) token burns.
