Spark collaborates with Uniswap to launch stablecoin exchange system FX Layer

According to The Block, Spark and Uniswap have launched the stablecoin exchange system FX Layer, aimed at reducing institutional stablecoin trading slippage through shared liquidity pools. Spark will migrate $150 million from the USDS ecosystem to Uniswap v4, establishing a liquidity foundation for USDS, Tether's USDT, and PayPal's PYUSD. FX Layer acts as a shared liquidity and trading infrastructure on Uniswap v4, enabling stablecoin issuers to access a common system, Spark manages liquidity as an orchestration layer, and Uniswap provides a programmable AMM architecture.
