River: The Circulatory System for Your Crypto

Satoshi Protocol started with a narrow focus: unlocking Bitcoin liquidity.

We built a BTC-backed stablecoin and delivered the infrastructure needed for users to borrow against Bitcoin without selling it.

But as the market evolved, so did user behavior.

Capital no longer lives on a single chain. Users bridge assets daily, stake across ecosystems, and interact with multiple layers of infrastructure.

Meanwhile, stablecoin design remained static — bound to a single network or dependent on wrapped assets and bridges.

That disconnect became our reason to evolve.

We’ve now upgraded from a product to a system.

River is the result.

What is River?

River is the circulatory system for your crypto.

It connects capital, delivers yield, and turns contributions into rewards — the system for the full cycle of on-chain participation.

With River, you can:

• Deposit BTC, ETH, BNB, or LSTs as collateral — on the chain you already use
• Mint satUSD natively on your destination chain — no bridges, no wrapping
• Stake satUSD to earn yield from protocol strategies
• Post and provide liquidity to earn $RIVER and shape the system

River replaces fragmented workflows with one system.

It simplifies capital flow, aligns incentives, and rewards every action that grows the network.

Why We Built River

Satoshi Protocol began by unlocking Bitcoin liquidity. It worked, but the market moved faster.

Capital no longer lives on one chain. Users move across ecosystems. Liquidity is scattered, and the tools to use it are fragmented.

We needed a system that reflects how capital actually moves.

River is that system.

It lets users deposit BTC, ETH, BNB, or LSTs on source chain, mint stablecoins on destination chain, and earn yield by using the protocol. No bridges. No wrapping. Everything is native and composable.

River turns actions — minting, staking, posting — into ownership. It connects chains, compresses steps, and gives contributors a real stake in the system.

This isn’t a rebrand. It’s a new foundation for capital to move, earn, and belong.

What We’ve Built

Omni-CDP

Omni-CDP is the core of River’s system. It lets users deposit BTC, ETH, BNB, or LSTs on one chain and mint satUSD on another.

The process is native, fast, and does not rely on wrapped assets or third-party bridges.

River uses LayerZero messaging and the OFT standard to handle collateral syncing and satUSD issuance across supported chains.

This structure removes the need for bridges and allows users to interact directly with the chain where they need liquidity.

Compared to systems like Ethena, Maker, and Usual, River offers three distinct advantages:

• Cross-chain minting : Users deposit on Chain A and mint on Chain B without wrapping or bridging.
• Multi-asset collateral : Supports BTC, ETH, BNB, and major LSTs. This expands the range of capital that can be deployed into stablecoin issuance.
• Integrated yield design : satUSD staking yield comes from protocol revenues. This gives users access to structured returns beyond stability.

In addition to minting, users can also swap USDT or USDC for satUSD at 1:1 on supported chains, making satUSD easily accessible without using collateral.

For example, a user can deposit wBTC on Ethereum, mint satUSD on BNB Chain, or simply swap USDC into satUSD — and immediately use that liquidity in DeFi or stake it for yield.

No waiting, no asset transfer delays.

satUSD isn’t just a stablecoin. It’s a native onchain instrument for liquidity, yield, and participation.

satUSD Staking

satUSD isn’t just for liquidity — it’s built to earn.

Users can stake satUSD to receive satUSD+, a yield-bearing version of the stablecoin.

Yield is sourced from protocol revenue, including minting fees, liquidation penalties, redemption fees, and other system-level income.

This makes satUSD a productive on-chain asset — held not just for stability, but for return.

It’s built for users, LPs, and DAOs who want to stay liquid while earning real yield.

4FUN

4FUN is River’s contribution layer. It rewards influence, not just capital.

By linking your X account and posting about River or other projects you support, you earn River Points based on impressions, engagement, and consistency. No deposits or transactions are required.

Points convert into $RIVER through seasonal checkpoints. 4FUN turns social impact into ownership and invites anyone to contribute to River’s growth through visibility rather than liquidity.

Season 2 Airdrop Is Live

We launched Season 2 on May 15.

Participation is tracked through actions that add value to the protocol. All contributors earn $RIVER Points, which convert to $RIVER after TGE.

Ways to earn:

• Mint satUSD by depositing BTC, BNB and other assets
• Swap USDT / USDC / fdUSD to get satUSD
• Stake satUSD to earn yield
• Provide satUSD-USDT liquidity on DEXs
• Link your X account and post through 4FUN
• Use satUSD on Lending, DEX and staking across chains

This round reflects our updated model — participation is measured across capital, usage, and community contributions.

About $RIVER

$RIVER is the only governance asset of the protocol, earned through checkpoints based on user actions like minting, staking, content creation, and usage.

Holding $RIVER grants voting power, access to protocol rewards, and influence over product and network direction.

Emissions are controlled seasonally, with long-term staking multipliers and revenue-based redistribution mechanisms.

Current Stats

• TVL: 124M
• satUSD in circulation: 22M
• Deployed on: Hemi, Arbotrim, BNB Chain, Base, BOB and BSquared

What's Next

We’re expanding satUSD into new ecosystems and integrating with DeFi protocols across supported chains. Lending markets, liquidity incentives, and stablecoin utilities are coming soon.

4FUN will go live this May. Share the projects you support, amplify their impact on X, and start earning River Points.

The TGE is also on the roadmap. We’re working closely with key partners to align liquidity, listing, and long-term participation.

Final Note

River is more than a protocol. It is an infrastructure layer for your crypto — designed for those who contribute, not just those who hold.

We’re building for users who stake, mint, post, and govern.
