Spark and Uniswap Launch "FX Layer" with $150 Million Liquidity to Kickstart Stablecoin Exchange Infrastructure

Odaily reports that Spark and Uniswap have announced a partnership to launch "FX Layer," a stablecoin exchange system designed for institutions, aiming to achieve low-slippage, high-efficiency swaps between dollar-pegged tokens. Built on Uniswap v4, this system serves as a shared liquidity and trading infrastructure, enabling stablecoin issuers such as banks, fintech companies, and payment institutions to access a unified exchange network without needing to build their own liquidity pools or market-making systems.

In terms of architecture, Spark is responsible for the liquidity scheduling and governance coordination layer (FX orchestration layer), while Uniswap provides the programmable automated market maker (AMM) underlying framework. As an initial measure, Spark will migrate approximately $150 million in liquidity from its USDS ecosystem to Uniswap v4, establishing basic exchange pools for USDS, Tether (USDT), and PayPal's PYUSD. Analysts suggest that this partnership is set against the backdrop of accelerating institutional stablecoin issuance and growing market expansion expectations following the passage of the GENIUS Act. As the total market capitalization of stablecoins grows, cross-issuer interoperability is becoming a core infrastructure need. (The Block)
