mStable

mStable receives a C risk grade (45/100) from Hindenrank, where lower scores indicate lower risk. mStable's mPT-sUSDe vault offers compelling yield but carries significant risk from its leveraged, multi-protocol architecture. Suitable only for risk-aware DeFi users who understand the liquidation mechanics. Not appropriate for conservative stablecoin holders seeking safe yield. mStable's mPT-sUSDe vault offers ~15% APY by combining Ethena's sUSDe yield with Pendle fixed-rate tokens and Aave leveraged looping (up to 7.5x). This is a sophisticated yield strategy that stacks three DeFi protocols together. While the returns are attractive, the leverage means losses are amplified — a modest stablecoin depeg could trigger cascading liquidations. The original mStable protocol was rebuilt in late 2025 with this new vault architecture.

The key risks identified for mStable are: (1) High leverage (7.5x) means small price moves cause big losses (2) Depends on Ethena's basis trade working — if funding rates flip negative, yield disappears (3) Three protocols stacked together means three times the smart contract risk (4) New vault architecture with limited track record despite the mStable name
