Svmuu News: Sky (formerly MakerDAO), in collaboration with Spark and Uniswap, announced that the initial $150 million in liquidity for FX Layer—a stablecoin exchange system jointly developed by the three parties—comes entirely from USDS, the stablecoin within the Sky ecosystem. As the platform’s core pricing asset, USDS provides foundational liquidity for the USDS/USDT and USDS/PYUSD trading pools, marking the first large-scale implementation of this shared liquidity framework.
The three parties’ long-term plan is to integrate institutions expanding into the stablecoin business—such as PayPal’s PYUSD, Ripple’s RLUSD, Robinhood, and Revolut—into a unified infrastructure, eliminating the costs for individual issuers to independently build liquidity pools and market-making systems. At the same time, a supporting governance mechanism ensures that idle funds not participating in market-making continue to generate returns.
On June 25, Spark and Uniswap officially announced the launch of the FX Layer. The architectural division of labor is clear: Spark acts as an orchestration layer to allocate cross-stablecoin liquidity, while Uniswap v4 executes trade paths through the DualPool hook’s programmable AMM mechanism, providing one-stop stablecoin exchange services to banks, fintech firms, and payment companies.
