River is building a chain-abstracted stablecoin system that connects assets, liquidity, and yield across diverse ecosystems. Powered by satUSD, a cross-chain CDP stablecoin, this system allows users to achieve yield, leverage, and scale across multiple ecosystems. Going beyond traditional models, River has innovatively launched PrimeVault and SmartVault, combining collateral flexibility with automated, liquidation-free yield strategies to achieve seamless multi-chain scalability.
