In-depth Analysis of the River Project and satUSD Cross-Chain Stablecoin
Core Mechanism: Full-chain Cross-chain Collateral Minting and No-Bridge Design
The underlying logic of satUSD is an over-collateralized stablecoin, generated using mainstream crypto assets such as BTC, ETH, BNB, and LST (like wstETH) as collateral, with a collateralization ratio set at 110%-120%, and supports zero-interest minting. Its core innovation lies in the deep integration of LayerZero's OFT (cross-chain asset standard) and OApp (cross-chain application protocol), achieving a no-bridge cross-chain experience of "one-chain collateral, multi-chain minting"—users can deposit collateral assets (like Bitcoin) on chain A, synchronize collateral rights and debt positions through LayerZero's cross-chain messaging, and directly mint satUSD on chain B without relying on third-party bridging tools or wrapped assets, ensuring unified total supply and seamless liquidity connection
