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.

OpenZeppelin is the gold standard for smart contract security, providing audited contract libraries, security tooling, and professional audit services for projects building on HyperEVM and other EVM chains. The OpenZeppelin Contracts library—used by thousands of protocols worldwide—provides secure, gas-optimized implementations of ERC token standards, access control patterns, and DeFi primitives that HyperEVM developers rely on as foundational building blocks. OpenZeppelin Defender provides automated security operations including contract monitoring, automated incident response, and upgrade management through time locks and multi-sig governance. For protocols in the Hyperliquid ecosystem handling significant user funds, engaging OpenZeppelin for security audits provides the highest level of third-party validation, with OpenZeppelin's researchers having an unmatched track record in identifying vulnerabilities before they become exploits. Their open-source contract library has been the foundation of countless secure DeFi protocols.

Ecosystem Integration
Mountain Protocol
Mountain Protocol operates on Multi-Layer (spans multiple hyperliquid layers). Spanning multiple layers lets it combine the strengths of each, though integration complexity is higher.
OpenZeppelin
OpenZeppelin operates on Multi-Layer (spans multiple hyperliquid layers). Spanning multiple layers lets it combine the strengths of each, though integration complexity is higher.
Both protocols share the same layer, maximizing composability potential.
