Uniswap Labs has launched aggregator hooks on Ethereum, Base and Robinhood Chain, allowing Uniswap v4 to route trades through liquidity held on other platforms. Fluid, Curve and PancakeSwap are among the external sources available at launch. The hooks work through both the Uniswap web app and its API on all three networks, and the company said more blockchains are planned.
Each hook wraps an external liquidity source so that routers treat it as a Uniswap v4 pool. Uniswap then compares prices across its own pools and the external venues and completes the trade in a single transaction. In the web app the external sources are included automatically, while developers using the API can route trades through the hooks.
Trades that use external liquidity pay Uniswap protocol fees, which contribute to UNI token burns. The first aggregator hook went live in March 2026 on Tempo, a payments-focused blockchain developed by Stripe and Paradigm, where only the web app is supported. Uniswap first proposed the feature in its UNIfication proposal in November 2025, describing it as turning v4 into an aggregator.
Uniswap Labs said the protocol has processed more than $4.5 trillion in total trading volume. The rollout to Ethereum, Base and Robinhood Chain is the first time the hooks are available through the API as well as the web app, with further networks to follow.
