Is Felix Vaults Safe?
Risk Grade: C+ (36/100)
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
100% dependent on Hyperliquid — if the chain goes down, Felix goes down with it
Exotic collateral types (vault tokens) create recursive risk loops that amplify losses
Security auditor flagged oracle pricing vulnerabilities that could lead to bad debt
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

Common Questions about Felix Vaults
Plain-English answers based on Felix Vaults's scores across Hindenrank's 8 risk dimensions. The highest-scoring (riskiest) dimension is Vitality Risk (6/10).
Has Felix Vaults ever been hacked or exploited?
Felix Vaults has a fairly clean operational history. The track record dimension scored 5/15, indicating minor or no significant incidents on record. A clean track record is a positive signal but it does not guarantee future safety, especially as protocol complexity grows.
How much money is at stake in Felix Vaults?
Felix Vaults currently holds roughly $87M in user deposits. Smaller TVL means individual depositors carry a larger share of any loss event, and it can be harder to exit a position quickly during stress.
What's the worst-case scenario for Felix Vaults?
Hindenrank has identified specific collapse scenarios for Felix Vaults. The most prominent: "Hyperliquid Ecosystem Liquidity Crisis". The trigger condition is HYPE token drops 50%+ in 72 hours, simultaneously impairing Felix CDP collateral, draining feUSD liquidity, and reducing vault token values. Reading through the full scenario list on the protocol page is the single best way to understand the actual failure modes — generic "smart contract risk" is rarely the thing that takes a protocol down.
Is Felix Vaults regulated or insured?
Felix Vaults has low regulatory exposure on Hindenrank's framework (2/10). The protocol is structured in a way that minimizes counterparty and jurisdiction concentration, though regulatory risk in crypto can change rapidly. No DeFi protocol carries FDIC-style insurance — even with low regulatory risk, depositors are not protected in the way bank customers are.
What are the biggest red flags for Felix Vaults?
Hindenrank's retail-focused risk audit flagged: 100% dependent on Hyperliquid — if the chain goes down, Felix goes down with it Exotic collateral types (vault tokens) create recursive risk loops that amplify losses Security auditor flagged oracle pricing vulnerabilities that could lead to bad debt
