🔐 Security Knowledge | How to Resist DeFi Economic Model Attacks?
Economic model attacks are becoming more complex and more damaging than code vulnerability attacks. Here are the key points for project teams to build defenses:
✅ Design Phase:
Formal Verification: Use mathematical methods to prove the correctness of core financial formulas and state transition logic under different boundary conditions.
Extreme Parameter Testing: Simulate extreme inputs such as lightning loan-level funding scale to check whether the model may become uncontrollable.
✅ Audit Phase:
Specialized Model Audit: Hire a team of experts with a background in financial engineering or mathematics to conduct an independent evaluation of the economic mechanisms.
Simulated Attack Drills: Require the auditing party to perform 'white-hat attacks' to attempt to find arbitrage or manipulation paths within the model.
✅ Risk Control Phase:
Introduce Rate Limits: Set frequency and amount hard caps on users' key operations to increase the cost and complexity of attacks.
Establish Monitoring Alerts: Monitor core metrics of the protocol (such as reward distribution rate, collateralization ratio) in real-time and set abnormal thresholds.
💎 Core Principle:
In DeFi, the economic intent implemented in code must be complete and robust. A thorough audit of the economic model may be the most important investment to avoid 'textbook-level' failures.
