River establishes an on-chain capital circulation system and reconstructs the logic of stablecoins and value allocation

As the total market value of crypto assets approaches US$3 trillion , more than 300 Layer2 exist at the same time , and hundreds of income assets (such as LST) are parallel to more than 30 stablecoins , the on-chain capital system is prospering, but in fact it is divided:

• Assets and strategies are distributed in different chains and are difficult to coordinate
• Stablecoins are designed in different ways, and liquidity cannot be concentrated
• Weak governance and participation mechanisms and lack positive cycles

River (formerly Satoshi Protocol) officially announced the upgrade to a complete on-chain capital circulation system, focusing on solving the above structural problems. Through the three major modules Omni-CDP, Yield, and 4FUN , River has established a cross-chain integration and community-driven capital cycle, and redefined stablecoins as a hub for on-chain value flow.

• Omni-CDP : Supports assets such as BTC, ETH, BNB as collateral and cross-chain stablecoin minting
• Yield : Return the agreement income and cooperation strategy returns to the satUSD stakeholder
• 4FUN : As a dynamic incentive mechanism for the contributions layer in the River system based on user behavior, community interaction and on-chain participation

Through these three layers of design, River has established a circulation system from asset generation → circulation value-added → return allocation → governance participation , allowing on-chain capital to achieve organic circulation in a safer and more sustainable way in a multi-ecology.

**Omni-CDP: The basic layer of capital generation and cross-chain

casting**

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

Users can choose to deposit BTC, ETH, BNB or their LST (such as solvBTC, wstETH) on any support chain (such as Ethereum, BNB Chain, Hemi) and cast satUSD natively on the other chain.

Omni-CDP integrates LayerZero's OApp communication protocol, while satUSD adopts the OFT standard to achieve real-time circulation between multiple chains, coordination of collateral information synchronization and liquidation mechanisms . Therefore, no third-party bridge or additional liquidity is required when transferring satUSD, which greatly improves 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 coin" and can manage liquidity in real time; the protocol has been deployed on BNB Chain, Arbitrum, Base chain, etc. TVL has accumulated US$125 million and satUSD has been circulated for more than US$20 million.

satUSD: a stablecoin that supports income and full-chain liquidity

satUSD is an over-collateralized stablecoin that currently supports 0% interest on coin minting, including BTC, ETH, BNB (110%–120% collateral ratio) and mainstream LST (120–150% collateral ratio) to maximize user capital efficiency and strategic flexibility.

Currently satUSD has been deployed to BNB Chain, Arbiturm, Base, Hemi and other ecosystems, and can provide liquidity in DEXs such as PancakeSwap, Oku, etc., and can also lend USDT as a lending platform to mortgage assets, implement interest rate spread strategies, and combine stability and flexible returns to diversified scenarios.

In addition, satUSD can be further pledged as satUSD+, and the benefits generated by sharing the agreement include minting, liquidation costs and redemption costs, allowing users to participate in the positive cycle of the agreement value while maintaining liquidity.

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

4FUN: River 's contribution layer makes influence an asset

In traditional finance and most DeFi protocols, participation and rewards are almost exclusively targeted at capital investment. But in fact, the growth and spread of products and agreements often come from community-initiated participation and dissemination

4FUN is the Contributions Layer in the River protocol to measure and give back to the contributions of the community.

Users only need to bind an X account and share relevant content with River or your support for ecological projects, and they can obtain River Pts based on the number of touches, interactions and stability, without any pledge or on-chain operations.

River Pts will be redeemed as $RIVER governance tokens when settlement is held at TGE, representing users' participation and influence in product and protocol promotion, and thus obtaining future airdrop and governance rights.

4FUN fills the blind spots of the capital system on the chain, so that community voice and content influence can also become a part of governance and value distribution, and transforms participation behavior into substantial ownership rights

Progress and future plans at this stage

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

• Total locked position (TVL) exceeded US$125 million
• SatUSD circulating volume up to 20 million US dollars
• More than 5,000 stablecoin holders
• Support mortgage assets: BTC, ETH, BNB, solvBTC, etc.
• Deployed chains: BNB Chain, Base, Arbitrum, Hemi, BSquared, etc.
• More than 20 protocols including Oku, PancakeSwap, Spectra, LayerBank, Pell, Segment, etc. have been integrated

In the future, River will continue to expand satUSD application scenarios and deploy them to various Layer2 ecosystems; and will release 4FUN in the near future, encouraging users to link X and participate in the acquisition of token allocation and governance rights.

About River

River is an on-chain capital circulation system established on the Omni-CDP architecture, supporting cross-chain collateralization, stablecoin minting, income distribution and community contribution governance. The stablecoin satUSD integrates LayerZero technology and issuanced with OFT standards to achieve the circulation of full-chain liquidity, and combines satUSD+ and 4FUN to complete a complete dead cycle from assets, income to influence contribution.
