River is building a chain-abstraction stablecoin system that enables cross-chain collateral, yield, and liquidity—all without bridging. Powered by the omni-CDP stablecoin satUSD, users can earn, leverage, and scale across different ecosystems natively. River features the first omni-CDP module that allows users to collateralize assets on Chain A and mint stablecoin satUSD on Chain B—without bridging the assets.
