A capital coordination layer now live across one of Ethereum’s most active ecosystems
River has officially deployed on Arbitrum, expanding access to satUSD and bringing its capital, yield, and contribution system to a broader DeFi audience.
This launch introduces native satUSD minting and liquidity provisioning on Arbitrum, allowing users to deploy capital and earn through staking, trading, and participation—without bridges or wrappers.
satUSD: Native, Overcollateralized, and Omni-Chain
satUSD is an overcollateralized stablecoin backed by wETH, wBTC, clBTC (Cygnus), and other liquid staking tokens.
Built on the OFT standard and powered by LayerZero, satUSD enables users to deposit collateral on one chain and mint satUSD natively on another.
It simplifies cross-chain liquidity without compromising security or capital efficiency.
Users can stake satUSD to earn protocol revenue, use it as liquidity, or deploy it across applications on Arbitrum and other supported networks.
Why Arbitrum
Arbitrum leads Ethereum Layer 2s in activity, liquidity, and developer adoption. Its composable DeFi ecosystem supports high-throughput strategies at lower cost, making it an ideal environment for River’s stablecoin and yield infrastructure.
River’s deployment brings satUSD into this ecosystem with full support for minting, staking, and liquidity provisioning on Arbitrum-native apps.

About River
River is building a circulatory system that connects capital, yield, and contribution across chains. Through three core modules—Omni-CDP, Yield, and 4FUN—River forms a modular capital coordination layer.
It enables users to access stablecoin liquidity, earn protocol rewards, and convert participation into on-chain ownership. At the center of this system is satUSD, an overcollateralized stablecoin that powers value creation and value circulation across ecosystems.
