River Unveils Circulatory System to Power Stablecoin Liquidity and Contribution

Satoshi Protocol has officially upgraded to River, a unified on-chain capital system designed to solve fragmentation in liquidity, strategy coordination, and governance participation. The protocol now integrates three modules—Omni-CDP, Yield, and 4FUN—forming a continuous loop that connects capital, yield, and contribution across chains.

The upgrade reflects a response to deeper issues in today’s crypto landscape. While nearly $3 trillion market cap, with over 300+ Layer2, hundreds of yield assets ( LST ) , and dozens of stablecoins, structural problems remain:

• Assets and strategies are scattered across chains, with limited coordination
• Stablecoin liquidity is fragmented by incompatible designs
• Governance systems lack user engagement and reward alignment

River addresses these limitations with a full-cycle framework that turns stablecoins into infrastructure for capital and contributions. 

An Upgrade Built to Unify Capital, Yield, and Contribution

The upgrade transforms Satoshi Protocol from a single-product stablecoin platform into a full-stack capital system. River introduces three functional modules:

• Omni-CDP, which allows multi-chain collateralization and native stablecoin minting
• Yield, which redistributes protocol revenue to stakers of satUSD+
• 4FUN, which measures and rewards user contribution based on social participation

Together, these layers complete a loop from asset creation to community governance, enabling River to function as an omni-chain circulatory system for any ecosystems. 

Omni-CDP : Omni-Chain Liquidity as Foundational Layer

Omni-CDP is the foundation of River’s upgrade. It allows users to deposit BTC, ETH, BNB, or LSTs such as solvBTC and wstETH on source chain and mint satUSD natively on destination chain. This eliminates the need for wrapped assets or third-party bridges.

The system uses LayerZero’s OApp and the OFT standard to keep collateral data, liquidation logic, and stablecoin balances synced in real time across chains.

River’s Omni-CDP is live on BNB Chain, Arbitrum, Base, and Hemi. To date, River has accumulated $125 million in total value locked, with over $20 million in satUSD circulation.

satUSD: Over-Collateralized, Zero-Interest Stablecoin With Yield Access

satUSD is an over-collateralized stablecoin backed by BTC, ETH, BNB, and leading LSTs, with collateral ratios ranging from 110% to 150 %. Minting incurs zero interest, allowing users to access liquidity without selling assets.

satUSD is live across major chains and can be used on PancakeSwap, Oku, and lending protocols to provide liquidity or borrow against it. 

Users can also stake satUSD to earn satUSD+, a liquid token that shares protocol revenue from minting, redemption, and liquidation fees.

As part of River’s Season 2 airdrop, users who provide liquidity to the satUSD-USDT pool can earn 50x River pts. More details are available on River’s staking page.

4FUN：A Contribution Layer That Rewards Impact

4FUN is River’s contribution layer, designed to reward the behaviors that help grow an ecosystem—regardless of capital. While traditional protocols prioritize deposits, 4FUN measures user participation through content, engagement, and influence.

Users connect their X accounts and share River or project-related content. Based on content, engagement, and impressions, they earn River Pts, which require no staking or on-chain action. These points will convert into $RIVER tokens at TGE.

4FUN closes the loop between protocol use and community momentum. It brings visibility and value to the voices that educate, promote, and expand the ecosystem—turning attention and action into a measurable part of the system.

Milestones and Ecosystem Growth

Since upgrading to River, the protocol has reached:

• $125 million in total value locked
• $20 million in satUSD supply
• Over 20k satUSD holders
• Supported collateral: BTC, ETH, BNB, solvBTC
• Deployed chains: BNB Chain, Arbitrum, Base, Hemi, BSquared
• Integrated with 20+ protocols including PancakeSwap, Oku, Spectra, LayerBank, Pell, and Segment

River plans to expand satUSD integrations across new Layer2 ecosystems and launch the full version of the 4FUN contribution layer.

About River 

River is the upgraded version of Satoshi Protocol, now operating as a circulation system for crypto. It supports stablecoin minting through Omni-CDP, protocol revenue sharing via satUSD+, and ecosystem growth through the 4FUN contribution layer. 

satUSD is issued using LayerZero’s OFT standard, enabling real-time cross-chain liquidity without fragmentation. River builds a capital system where value flows from capital to contribution.
