🚨 Case Analysis | DeFi Economic Model Vulnerabilities Are Far More Concealed and Deadly Than Code Vulnerabilities
Last year, the DeFi protocol Margin Fund was exploited due to a critical mathematical formula defect in its reward calculation model, resulting in a loss of approximately 37 million dollars.
🔍 Root of the Vulnerability:
Attackers triggered a nonlinear amplification effect in the reward formula through a single massive deposit, illegally minting and selling a large amount of reward tokens, depleting the protocol's fund pool.
💡 Core Warning:
Economic Security ≠ Code Security: The deadliest vulnerabilities may be hidden in business logic and mathematical models, rather than in the lines of smart contract code.
Audits Must Cover Models: Before a protocol goes live, specialized economic model stress testing and formal verification must be conducted, simulating various extreme input conditions.
Set Safety Boundaries: Setting reasonable limits on key operations (such as single deposits/withdrawals) is an effective risk control measure against such precise attacks.
