A user deposits approved BTC, ETH, BNB or LST collateral into a chain-specific position. Protocol ratios, price feeds and liquidation logic limit satUSD debt. LayerZero carries the instruction that lets the destination system mint satUSD; OFT transfers burn or lock on one chain and mint or unlock on another.
The stablecoin uses overcollateralization, redemption and liquidation rather than a bank reserve. satUSD can be staked for satUSD+, whose stated return comes from protocol fees and strategies. RIVER can be time-locked for voting weight, boosts and discounts, but current documents use future tense for some powers and the OFT owner retains peer and security configuration.
The legal layer is thinner still. Ihsotas Ltd. is named as offeror, yet its white paper disclaims RIVER redemption, dividends, equity, issuer assets and guaranteed utility.
