MoUSD and RIFD are both decentralized USD-pegged stablecoins on RSK (Rootstock), Bitcoin's EVM sidechain, designed for uncensorable DeFi without central control like USDT/USDC. Key differences:
Issuer & Backing: MoUSD (Money on USD) is backed by diversified collateral like BTC, ETH, and rSKL, using oracle-based liquidations for stability. RIFD (RIF Dollar) is primarily overcollateralized by BTC via the Sovryn protocol, with algorithmic incentives for peg maintenance.
Minting: Both are on-demand and permissionless—lock collateral (e.g., RBTC) to mint, no fixed frequency. MoUSD supports broader asset types; RIFD focuses on BTC-centric minting.
Peg Mechanism: MoUSD relies on overcollateralization ratios (e.g., 150%) and automated liquidations. RIFD uses dynamic interest rates and rewards to arbitrage deviations from $1 peg.
Market Size: MoUSD has ~$10M cap; RIFD ~$5M (both small, growing via RSK's ecosystem like USDRIF protocol).
Integration: RIFD ties into RIF ecosystem (e.g., payments, DeFi); MoUSD integrates with broader RSK dApps like Sovryn lending.
Both are fully permissionless like Bitcoin—no freezes, anyone can interact via smart contracts. For details, check RSK docs or Sovryn site.
