Spark and Uniswap Jointly Build Stablecoin 'FX Layer', USDS Migrates $150 Million as Liquidity Base

CoinFeed June 25 news, according to The Block report, Spark and Uniswap are collaborating to launch the stablecoin 'FX Layer' on Uniswap v4, aiming to provide institutions with low-slippage USD stablecoin exchange infrastructure. This layer serves as a shared liquidity and settlement system, allowing stablecoin issuers such as banks, fintechs, and payment companies to access a unified pool without the need to build their own market-making and inventory management systems. Spark is responsible for liquidity allocation and governance coordination among different stablecoins, while Uniswap provides a programmable AMM architecture. As a launch measure, Spark will migrate $150 million in liquidity from its USDS ecosystem to Uniswap v4, establishing a 'liquidity base' for pools supporting USDS, USDT, and PYUSD.
