Uniswap says Aggregator Hooks route rival DEX fees into UNI burns

Key points

• Aggregator Hooks launched on 22 Oct 2026, connecting seven external liquidity sources to Uniswap v4 across Ethereum, Base and Robinhood Chain.
• Uniswap Labs says the connected sources cover more than 90% of DEX activity on those networks, with quotes refreshed every block.
• The feature builds on the UNIfication initiative approved in December 2025, which included a one-time treasury burn of 100 million UNI.

Uniswap Labs has launched Aggregator Hooks, a system that lets its Uniswap v4 protocol collect fees from trades routed through competing exchanges, with the proceeds going towards UNI token burns. The feature went live on 22 Oct 2026 and connects seven external liquidity sources across Ethereum, Base and Robinhood Chain, according to Bitcoin.com News.

Uniswap Labs said the connected sources account for more than 90% of decentralised exchange activity on those networks. The company described v4 as "now an aggregator", with outside liquidity appearing as native pools. Prices are compared across Uniswap and venues including Curve, Fluid, Pancakeswap V3 and Slipstream, and each trade settles in a single transaction.

Fees gather in TokenJar contracts, and the Firepit system requires UNI to be destroyed before those assets can be withdrawn. The initiative also authorised a one-time treasury burn of 100 million UNI.

Uniswap Labs said swaps routed through outside sources pay protocol fees that contribute to UNI burns. The feature is already live through Uniswap's Web App and API, with more networks and liquidity sources planned. For rival DEXs, the trade-off is extra volume from Uniswap users in exchange for fees flowing towards a competitor's burn mechanism.

What to watch: Uniswap says more networks and liquidity sources will be added to Aggregator Hooks, without giving a date.
