BlockBeats News, June 25th, Spark and Uniswap jointly launched the stablecoin exchange system "FX Layer." FX Layer is designed to help institutions trade between USD-pegged tokens by creating a shared pool for issuers to access, reducing slippage to a minimum.

Spark stated that it would move $150 million from its USDS ecosystem to Uniswap v4 to establish a "liquidity foundation" to support the interchange pool for USDS, Tether's USDT, and PayPal's PYUSD.

FX Layer serves as a shared liquidity and trading infrastructure on Uniswap v4, allowing multiple stablecoin issuers such as banks, fintech firms, and payment companies to access a universal system instead of individually building and launching their own liquidity pools, market makers, and inventory management. Spark, as the orchestration layer, determines how to allocate, manage, and coordinate liquidity among different stablecoins, while Uniswap provides a programmable AMM framework.
