🛡️ DEFI SECURITY: UNDERSTANDING ORACLE MANIPULATION
DeFi protocols often rely on price oracles to value collateral and execute financial operations.
⚠️ What can go wrong?
• 📊 An unreliable price feed reports an incorrect asset value
• 💰 A lending protocol miscalculates collateral
• 🔓 An attacker may exploit the incorrect valuation
• 📉 The protocol can suffer bad debt or financial losses
🛡️ Risk-reduction measures:
• Use reliable, decentralized oracle networks
• Validate data freshness and price deviations
• Consider TWAP mechanisms where appropriate
• Apply borrowing limits and circuit breakers
Key takeaway: Smart contract security depends on the quality of the data feeding the contract—not just the code itself.
