Uniswap launches DualPool Hook, allowing market makers to earn lending income from idle liquidity assets

Uniswap announces the official launch of DualPool Hook. DualPool is an open-source Uniswap v4 Hook, jointly designed and developed by Spark and Uniswap Labs, allowing market makers to earn yields by depositing idle assets into lending protocols during the waiting period for liquidity funds to be executed, and to withdraw funds back to the liquidity pool when a transaction occurs.

From an external perspective, DualPool is indistinguishable from a regular Uniswap v4 liquidity pool, and traders, aggregators, and solvers still complete transactions through the Pool Manager. Its internal mechanism is that liquidity funds are stored in an ERC-4626 yield vault and are automatically withdrawn when a transaction needs to be executed, deployed to concentrated liquidity positions, thereby ensuring transaction execution while allowing idle funds to continuously generate lending yields.
