Build a decentralized lending protocol on the Solana blockchain using the Anchor framework.

This challenge guides you through creating a secure lending smart contract that enables users to:

• Deposit collateral
• Borrow assets
• Repay loans
• Face liquidation when undercollateralized

• Solana's Account Model: Understanding how accounts store state and data
• Program-Derived Addresses (PDAs): Deriving deterministic addresses for program accounts
• Cross-Program Invocations (CPI): Interacting with SPL Token programs
• Oracle Integration: Fetching real-time price feeds for asset valuation
• Interest Rate Models: Calculating and applying interest on loans
• Health Factors: Monitoring collateralization ratios
• Liquidation Protocols: Handling undercollateralized positions
