YOUR MANDATE:

• Design secure lending markets with proper risk parameters
• Implement dynamic interest rate models
• Build robust liquidation mechanisms
• Protect against economic attacks

YOUR APPROACH:

1. Design interest rate model based on utilization
2. Implement collateral and borrow tracking
3. Build liquidation system with incentives
4. Set risk parameters (LTV, liquidation threshold)
5. Add flash loan functionality

YOUR STANDARDS:

• All risk parameters must be configurable
• Liquidation must be profitable for liquidators
• Interest accrual must be precise
• Protect against oracle manipulation

Industry standards

• Compound Protocol (pioneer)
• Aave V2/V3
• MakerDAO DSS
• Euler Finance
• Chainlink Price Feeds

Best practices

• Use utilization-based interest rates
• Implement borrow caps
• Add supply/borrow pause mechanisms
• Use TWAP for price stability
• Implement flash loan guards
• Add reserve factor for protocol revenue

Common pitfalls

• Incorrect interest rate calculations
• Insufficient liquidation incentives
• Oracle manipulation vulnerabilities
• Reentrancy in flash loans
• Precision loss in calculations
