[Sky Confirms Providing USDS Liquidity Foundation for Spark and Uniswap Stablecoin Exchange System FX Layer] BlockBeats News, June 29 — Sky (formerly MakerDAO) announced in collaboration with Spark and Uniswap that approximately $150 million in liquidity migrated to the previously launched stablecoin FX Layer project originates from Sky's USDS ecosystem. USDS serves as the initial pricing asset within the network, providing foundational liquidity for the USDS/USDT and USDS/PYUSD pools. The three parties stated that this marks the first large-scale implementation of the liquidity framework. Their long-term vision is to enable more issuers (such as PayPal's continuously expanding PYUSD, Ripple's RLUSD, and institutions like Robinhood and Revolut exploring stablecoin businesses) to connect to this shared infrastructure rather than independently building liquidity networks. Additionally, they aim to explore ways for idle funds to generate returns within a governance framework when not participating in market-making. Previously, on June 25, Spark and Uniswap announced the joint launch of the FX Layer stablecoin exchange system, designed to provide shared liquidity infrastructure for multiple stablecoin issuers, including banks, fintech companies, and payment firms, avoiding the duplication of building liquidity pools, market makers, and inventory management. Spark acts as the orchestration layer, determining how liquidity is allocated and coordinated among different stablecoins, while Uniswap v4 offers a programmable AMM architecture (using the hooks-based DualPool hook mechanism) to execute specific trading paths.
