# Welcome

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.

### **Core Modules**

#### **Omni-CDP**

The first cross-chain CDP system built on LayerZero’s OFT standard, enabling users to collateralize BTC, ETH, BNB, or LSTs on a source chain and mint satUSD natively on a destination chain—no bridges or wrappers required. 

* Deposit BTC, ETH, BNB, or LST as collateral and mint satUSD
* Swap USDT/USDC/USD1 for satUSD at 1:1 ratios

Mint/Swap to get satUSD : <https://app.river.inc/mint>

#### **Yield**

Stake satUSD to receive satUSD+, a yield-bearing token that shares protocol revenue.

River launches smart vaults where institutions and retail deposit BTC or ETH to earn real yield from DeFi strategies and protocol revenue, with no liquidation risk and flexible returns.
