Is Felix Vaults Safe?

|Yield
C+

Risk Grade: C+ (39/100)

Felix Vaults is rated as elevated risk — multiple novel mechanisms and notable interaction risks.

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.

Key Risks for Felix Vaults Users

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

Top Risk Factors

  • Built natively on Hyperliquid — inherits all risks of a relatively new L1 with limited battle-testing and concentrated validator set
  • Frontier Vaults expose users to exotic collateral types (UETH, hwHLP, WHLP) with complex multi-hop oracle pricing that can fail under stress
  • Liquity V2-style CDP system minting feUSD introduces novel redemption and liquidation dynamics that are untested at scale
