Mountain Protocol
Mountain Protocol is the issuer of USDM, a regulated, yield-bearing stablecoin backed by short-term US Treasury bills that automatically passes through Treasury yields to holders on a daily rebasing basis. Unlike traditional stablecoins that capture yield for issuers, USDM distributes approximately 4-5% APY directly to holders simply by holding the token—making it a compelling alternative to USDC and USDT in the HyperEVM ecosystem. As HyperEVM lending protocols and yield vaults integrate USDM as a base asset, Hyperliquid traders can earn real-world Treasury yields on their idle stablecoin balances between trades. Mountain Protocol operates under regulatory oversight and maintains full reserve attestations, providing institutional-grade compliance for DeFi protocols that need to satisfy regulatory requirements when deploying RWA-backed assets on Hyperliquid. USDM's daily rebasing model ensures yield accrues automatically without requiring any user action.
