Uniswap launched Aggregator Hooks on Oct. 22, 2026, connecting seven outside liquidity sources to Uniswap v4 across Ethereum mainnet, Base and Robinhood Chain. The feature is active through Uniswap’s Web App and API; Uniswap Labs says it compares prices with connected exchanges and settles routed trades in one transaction.
Uniswap Labs says swaps routed through outside sources pay protocol fees that contribute to UNI burns. The fee system stems from the UNIfication initiative approved in December 2025, which also authorized a one-time treasury burn of 100 million UNI. Additional networks and liquidity sources are planned.
