On July 23, 2026, Uniswap announced that its DualPool Hook has passed audit and is now open source. Developed in collaboration with Spark Finance, the tool enables teams to deploy their own version, allowing liquidity providers to earn rewards from both active and idle assets. The Hook deposits assets into an ERC-4626 vault and temporarily withdraws liquidity during swaps, returning funds after each transaction.
