River Protocol's cross-chain CDP (Omni-CDP) operations for minting satUSD:
Deposit collateral (e.g., BTC, ETH) on native chain A.
Mint satUSD directly on target chain B via app.
Use satUSD in DeFi; repay/burn to unlock collateral.
No bridging: Collateral stays on origin chain; state synced via LayerZero messaging and OFT standard.
Bridgeless design risk management: Avoids traditional bridge hacks/exploits. Relies on LayerZero's security (oracles, relayers), overcollateralization, real-time liquidations via cross-chain messages, Chainlink/DIA oracles for pricing, and multi-layer risk controls to maintain peg/solvency.
