River establishes an on-chain capital circulation system, reconstructing the logic of stablecoins and value distribution

As the total market capitalization of crypto assets approaches 3 trillion dollars, with over 300 Layer2 existing simultaneously, hundreds of yield assets (such as LST) and more than 30 stablecoins running in parallel, the on-chain capital system appears prosperous on the surface, but is actually fragmented:

• Assets and strategies are distributed across different chains, making collaboration difficult
• Stablecoin designs vary, preventing liquidity from being centralized
• Governance and participation mechanisms are weak, lacking positive feedback loops

River (formerly Satoshi Protocol) officially announces its upgrade to a complete on-chain capital circulation system, focusing on solving the above structural issues. Through three major modules Omni-CDP, Yield, 4FUN, River establishes a cross-chain integrated, community-driven capital cycle from asset generation, liquidity appreciation, yield distribution to contribution governance, redefining stablecoins as the hub for on-chain value flow.

• Omni-CDP: Supports BTC, ETH, BNB, and other assets as collateral for cross-chain stablecoin minting
• Yield: Returns protocol earnings and cooperative strategy rewards to satUSD stakers
• 4FUN: Acts as the Contributions Layer within the River system, utilizing a dynamic incentive mechanism based on user behavior, community interaction, and on-chain participation

Through this three-layer design, River has established a circular system from asset generation → liquidity appreciation → yield distribution → governance participation, allowing on-chain capital to circulate organically in a safer and more sustainable manner across multiple ecosystems.

Omni-CDP: The foundational layer for capital generation and cross-chain minting

River is built on Omni-CDP, which is not only a stablecoin module but also a capital and liquidity aggregation layer that can be deployed across multiple chains.

Users can choose to deposit BTC, ETH, BNB, or their LSTs (such as solvBTC, wstETH) on any supported chain (like Ethereum, BNB Chain, Hemi) and natively mint satUSD on another chain.

Omni-CDP integrates LayerZero's OApp communication protocol, and satUSD adopts the OFT standard to achieve real-time circulation, collateral information synchronization, and settlement mechanism coordination across chains. Therefore, transferring satUSD does not require third-party bridges or additional liquidity, significantly enhancing the efficiency and security of asset circulation.

This design makes River's Omni-CDP the only full-chain stablecoin protocol that truly realizes "A chain collateral, B chain minting" while managing liquidity in real-time; the protocol has currently been deployed on BNB Chain, Arbitrum, Base, and other chains, with a total value locked (TVL) of 125 million dollars and satUSD circulation exceeding 20 million dollars.

satUSD: A stablecoin supporting yield with full-chain liquidity

satUSD is an over-collateralized stablecoin, currently supporting BTC, ETH, BNB (110%--120% collateral ratio) and mainstream LSTs (120--150% collateral ratio). The minting interest rate is 0%, maximizing user capital efficiency and strategic flexibility.

Currently, satUSD has been deployed in ecosystems such as BNB Chain, Arbitrum, Base, and Hemi, and can provide liquidity on DEXs like PancakeSwap and Oku. It can also be used as collateral on lending platforms to borrow USDT, executing arbitrage strategies that combine stability with flexible yield in diverse scenarios.

Additionally, satUSD can be further staked as satUSD+, sharing the protocol-generated yields, including minting, liquidation fees, and redemption costs, allowing users to participate in the positive cycle of protocol value while retaining liquidity.

With the launch of the S2 Airdrop, providing liquidity for the satUSD-USDT stablecoin pool can earn 50x points; for details, please see River's Staking page.

4FUN: River's contribution layer, turning influence into assets

In traditional finance and most DeFi protocols, participation and rewards are almost exclusively tied to capital investment. However, the growth and dissemination of products and protocols often stem from community-driven participation and promotion.

4FUN is the Contributions Layer within the River protocol used to measure and reward community contributions.

Users only need to link their X account and share relevant content about River or the ecosystem projects they support to earn River Pts based on reach, interaction, and stability, without any staking or on-chain operations.

River Pts will be converted into $RIVER governance tokens at the time of TGE, representing the user's level of participation and influence in promoting products and protocols, thus gaining future airdrops and governance rights.

4FUN fills the blind spots in the on-chain capital system, allowing community voice and content influence to become part of governance and value distribution, transforming participation into tangible ownership.

Current Progress and Future Plans

As of May 2025, River has achieved the following milestones:

• Total value locked (TVL) surpasses 125 million dollars
• satUSD circulation reaches 20 million dollars
• Over 20,000 stablecoin holders
• Supported collateral assets: BTC, ETH, BNB, solvBTC, etc.
• Deployed chains: BNB Chain, Base, Arbitrum, Hemi, BSquared, etc.
• Integrated with over 20 protocols including Oku, PancakeSwap, Spectra, LayerBank, Pell, Segment, etc.

In the future, River will continue to expand the application scenarios of satUSD, deploying it to various Layer2 ecosystems; a recent release of 4FUN will encourage users to connect with X and participate in token distribution and governance rights acquisition.

About River

River is an on-chain capital circulation system built on the Omni-CDP architecture, supporting cross-chain collateral, stablecoin minting, yield distribution, and community contribution governance. The stablecoin satUSD integrates LayerZero technology and is issued under the OFT standard, achieving full-chain liquidity circulation, completing a complete cycle from assets and yields to influence contributions with satUSD+ and 4FUN.
