Felix Vaults

Felix Vaults receives a C+ risk grade (36/100) from Hindenrank, where lower scores indicate lower risk. An ambitious DeFi protocol bringing sophisticated leverage tools to Hyperliquid, but the combination of exotic collateral, complex oracle pricing, and dependency on a young L1 creates elevated risk. Three Sigma's audit provides some comfort, but the protocol is still early-stage with unproven resilience under stress. Suitable for risk-tolerant DeFi users who understand Hyperliquid's ecosystem. Felix Vaults is a modular leverage protocol built natively on Hyperliquid, offering two core products: a CDP system that mints feUSD stablecoin against crypto collateral, and Morpho-powered lending markets including Frontier Vaults for exotic collateral types. Felix gives Hyperliquid users access to leveraged yield strategies and stablecoin borrowing. However, it inherits all risks of the Hyperliquid ecosystem and introduces novel risks through its exotic collateral types and multi-hop oracle pricing, which have been flagged by security auditors.

The key risks identified for Felix Vaults are: (1) 100% dependent on Hyperliquid — if the chain goes down, Felix goes down with it (2) Exotic collateral types (vault tokens) create recursive risk loops that amplify losses (3) Security auditor flagged oracle pricing vulnerabilities that could lead to bad debt (4) feUSD is a new stablecoin with limited liquidity and unproven peg stability
