River contributed the following description of Smart Vault:

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.

Zellic conducted a security assessment for River from September 28th to October 2nd, 2025. During this engagement, Zellic reviewed Smart Vault's code for security vulnerabilities, design issues, and general weaknesses in security posture.
