The open-source feature, designed with Spark and Uniswap Labs, routes idle assets into ERC-4626 vaults and pulls them back into concentrated liquidity positions when trades need to be executed.
Uniswap said its open-source DualPool hook is now live, adding that the feature was jointly designed by Spark and Uniswap Labs. The hook allows market makers to place idle assets into lending protocols through ERC-4626 vaults while they wait for trades, then automatically move those funds back into concentrated liquidity positions when execution is needed. The release expands on Uniswap’s earlier description of the tool as audited, open source and ready for implementation, and sharpens its focus on capital efficiency in DeFi by helping users seek returns on assets that would otherwise sit unused.
