Uniswap, Spark Launch DualPool to Put Idle Liquidity to Work

Liquidity providers on decentralized exchanges typically leave capital in pools while waiting for trades, limiting the return on funds that are not actively deployed. Uniswap Labs and Spark developed DualPool, an open-source Hook designed to improve that capital efficiency by placing idle liquidity into yield-bearing vaults. The structure could allow LPs to earn vault income alongside trading fees without permanently withdrawing funds needed for market making.

DualPool has now gone live, with capital deposited into a yield vault while it waits for a designated price to be reached. Once the market enters the relevant range, the funds are pulled back into the Uniswap pool to execute trades. As of July 23, 2026, Uniswap Labs and Spark had not disclosed the amount of capital using the system, targeted yields or detailed costs, but released the code for broader integration.
