What’s LayerZero?
LayerZero is an omnichain interoperability protocol that enables seamless communication between different blockchains. It allows developers to build omnichain applications (OApps) that can interact across multiple chains as if they were on a single chain.
What is satUSD?
satUSD is an over-collateralized stablecoin backed by BTC, ETH, BNB, and other liquid staking tokens (LSTs). It lets users access liquidity without selling their assets and earn yield by staking satUSD to share protocol revenue.
What is Omni-CDP?
River has launched V2, introducing the first Omni-CDP integrated with LayerZero to enable omnichain liquidity management for BTC, ETH, BNB and LST.
With this upgrade, users can deposit BTC or BTC LSTs (e.g., solvBTC, LBTC) on any supported chain and seamlessly mint satUSD on a destination chain.
This architecture enhances BTC liquidity across ecosystems, unlocking new opportunities for yield, trading, and capital efficiency.
What makes satUSD different from other stablecoins?
satUSD is a universal stablecoin backed by Bitcoin. It offers greater transparency and user control compared to fiat-backed centralized stablecoins.
How can I mint satUSD?
You can deposit BTC, ETH, BNB and LST as collateral on the source chain and choose to mint satUSD on a destination chain.
To ensure the stability of your position, a minimum collateral ratio (MCR) is required: 110% for BTC and 120%-150% for LSTs, though the exact ratio may vary depending on the specific asset
What is gas compensation?
Gas compensation refers to a small reserve of satUSD set aside to cover transaction fees associated with the liquidation of your position.
How does satUSD maintain its peg to the US dollar?
satUSD maintains its peg through over-collateralization, an instant liquidation module, and a peg mechanism.
If satUSD drops below $1, arbitragers can purchase discounted satUSD and redeem it for $1 worth of BTC from the protocol.
If satUSD exceeds $1.10, users can mint satUSD at 110% MCR and sell it immediately on the market.
Why is my position liquidated?
If your position’s collateral ratio fall below 110%, it will be allowed to trigger liquidation, which mean your collateral will be sold to stability pool providers for satUSD to repay your debt.
How can I avoid liquidations?
To avoid liquidations, maintain a healthy collateralization ratio, typically above 150%. You can add collateral to your position or repay part of your debt to improve the ratio and prevent liquidation.
How can I close position and claim my collateral?
You can close your position by repaying your satUSD debt in full. Once the debt is repaid, you can claim your collateral.
How does Recovery Mode work?
During Recovery Mode, actions are taken to improve the Total Collateral Ratio (TCR) to 150%:
Positions with a collateral ratio below 150% are liquidated.
Minting is restricted to maintaining a 150% Minimum Collateral Ratio (MCR).
To incentivize recovery, the minting fee is set to 0%.
