River establishes an on-chain capital circulation system to reconstruct stablecoins and value distribution logic

With the total market capitalisation of crypto assets approaching $3 trillion, more than 300 Layer 2s coexisting, and hundreds of yield assets (such as LST) running parallel to more than 30 stablecoins, the on-chain capital system is prosperous on the surface, but in fact it is fragmented:

Assets and strategies are distributed in different chains, making it difficult to coordinate
Stablecoins are designed differently, and liquidity cannot be centralised
Governance and participation mechanisms are weak, and there is a lack of positive circulation

River (formerly Satoshi Protocol) has officially announced its upgrade to a complete on-chain capital circulation system that focuses on solving the above structural problems. Through the three modules of Omni-CDP, Yield, and 4FUN, River has established a cross-chain integration, community-driven capital cycle from asset generation, liquidity appreciation, income distribution to contribution governance, and redefined stablecoins as a hub for value flow on the chain

Omni-CDP: Support BTC, ETH, BNB and other assets as collateral and cross-chain stablecoin minting
Yield: Return the protocol yield and cooperative strategy rewards to satUSD stakers
4FUN: As a Contributions Layer in the River system, it is a dynamic incentive mechanism based on user behaviour, community interaction, and on-chain participation

Through these three-layer design, River has established a circular system from asset generation→ circulation appreciation→ return distribution, → governance participation, so that on-chain capital can be organically circulated in a safer and more sustainable way in multiple ecosystems

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

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 on multiple chains

Users can choose to deposit BTC, ETH, BNB, or their LSTs (e.g., solvBTC, wstETH) on any of the supported chains (e.g., Ethereum, BNB Chain, Hemi) and natively mint satUSD 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, synchronisation of mortgage information and coordination of clearing mechanism, so there is no need for third-party bridges or additional liquidity 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 realises "A-chain collateralization and B-chain minting" and can manage liquidity in real time. The protocol has been deployed on BNB Chain, Arbitrum, Base Chain, etc., with a cumulative TVL of $125 million and more than $20 million in satUSD in circulation

satUSD: A stablecoin with yield-backed and full-chain liquidity

satUSD is an overcollateralized stablecoin that currently supports BTC, ETH, BNB (110%–120% collateral) and mainstream LST (120–150% collateral) with 0% minting interest to maximise users' capital efficiency and strategic flexibility

At present, satUSD has been deployed to BNB Chain, Arbiturm, Base, Hemi and other ecosystems, and can provide liquidity on DEXs such as PancakeSwap and Oku, and can also be used as a collateral asset on the lending platform to lend USDT, implement interest rate spread strategies, and combine multiple scenarios of stability and flexible returns

In addition, satUSD can be further pledged as satUSD+ to share the revenue generated by the protocol, including minting, liquidation fees and redemption costs, allowing users to participate in the positive cycle of the protocol's value while maintaining liquidity

With the launch of S2 Airdrop, 50x credits are now available for the satUSD-USDT stablecoin liquidity pool; See River's Staking page for details.

4FUN: River's contribution layer, making influence an asset

In traditional finance and most DeFi protocols, participation and rewards are almost exclusively for capital investment. But in fact, the growth and proliferation of products and protocols often comes from community-initiated participation and dissemination

4FUN is the Contributions Layer in the River Protocol to measure and give back to the community.

Users only need to bind X account and share content related to River or the ecological projects you support, and they can obtain River Pts according to the number of touches, interactions, and stability, without any staking or on-chain operations.

River Pts will be exchanged for $RIVER governance tokens at the time of settlement at TGE, representing users' participation and influence in the promotion of products and protocols, and then obtaining future airdrop and governance rights.

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

Current progress and future plans

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

The total locked position (TVL) exceeded $125 million
satUSD has a circulating supply of $20 million
More than 5,000 stablecoin holders
Supported collateral assets: BTC, ETH, BNB, solvBTC, etc
Deployed chains: BNB Chain, Base, Arbitrum, Hemi, BSquared, etc
It has integrated more than 20 protocols such as Oku, PancakeSwap, Spectra, LayerBank, Pell, Segment, etc

In the future, River will continue to expand the application scenarios of satUSD and deploy it to various Layer2 ecosystems. In the near future, 4FUN will be released to encourage users to link X, participate in token distribution and obtain governance rights

About River

River is an on-chain capital circulation system built on the Omni-CDP architecture, supporting cross-chain collateralization, stablecoin minting, revenue distribution, and community contribution governance. The stablecoin satUSD integrates LayerZero technology and issues it according to the OFT standard to realise the circulation of full-chain liquidity, and combines satUSD+ and 4FUN to complete a complete cycle from assets, income to impact contribution.
