Woofun AI reports that Uniswap has officially launched the DualPool Hook, an open-source Uniswap v4 module co-developed with Spark. This mechanism enables market makers to deposit idle liquidity into lending protocols to generate yields, automatically recalling funds when trades occur. To external observers, DualPool functions identically to standard v4 pools, with transactions routed through the Pool Manager. Internally, it utilizes an ERC-4626 yield vault to store assets, withdrawing them only for concentrated liquidity deployment during trade execution, thus combining transactional utility with passive income generation.
