Uniswap v4 Is Now an Aggregator: Uniswap Labs Launches Aggregator Hooks
New York, New York, October 22nd, 2026, Chainwire
Uniswap Labs today launched Aggregator Hooks, new v4 hooks that wrap external liquidity sources and turn them into Uniswap pools. Aggregator Hooks are now live in the Uniswap Web App and API on Ethereum mainnet, Base, and Robinhood Chain. Seven sources are available at launch, covering more than 90% of all DEX activity on these chains.
The Uniswap Protocol is the largest decentralized exchange by volume, with more than $4.5 trillion swapped. Even so, new liquidity can still form elsewhere. Aggregator Hooks bring that liquidity into the protocol. Outside sources become v4 pools, and swaps routed through them pay protocol fees, contributing to UNI burn.
Each Aggregator Hook wraps an external source in a Uniswap v4 hook, so any router sees it as a Uniswap pool. Every block, the router pulls fresh quotes from the connected sources and builds the most efficient route across Uniswap pools and outside sources. The whole route settles in a single transaction, with nothing new for a user to approve.
Swaps on the Uniswap Web App now include external liquidity sources automatically. Developers can route through Aggregator Hooks using the Uniswap API. Learn more about hooks developed by Uniswap Labs.
