Uniswap Labs launched a feature called Aggregator Hooks on Thursday, wiring seven external liquidity sources across three networks — including Ethereum and Base — directly into Uniswap v4.

According to the company, the sources connected through the feature account for more than 90% of trading activity across decentralized exchange (DEX) markets.

That coverage figure underscores how fragmented DEX liquidity has become across many pools and venues. Aggregators — services that route orders across multiple venues rather than a single protocol — emerged to address this fragmentation, aiming to tap the deepest available liquidity for a given trade. By building aggregation into v4 itself, Uniswap Labs is bringing that capability inside the protocol rather than leaving it to separate services.

Aggregator Hooks build on the hook architecture introduced with Uniswap v4, which allows external smart contracts to customize how liquidity pools and swaps behave within the protocol. The new feature applies this mechanism to aggregation, enabling trades to route not only through Uniswap's own pools but also across outside liquidity venues.

Uniswap is one of the most widely used decentralized trading protocols in the industry. Its fourth version, Uniswap v4, went live in early 2025 with hooks as its flagship capability, letting developers attach custom logic to liquidity pools.

Ethereum, where the Uniswap protocol was first deployed, and Base, a layer-2 blockchain incubated by Coinbase, are two of the three networks supported by the new feature. How the routing holds up across the seven sources in live trading, and whether Uniswap Labs extends coverage to additional venues or networks, will be developments to follow.
