Impermanent Loss & Lending Pool Risks

Overview

Understand the unique risks of DeFi lending and liquidity provision. Impermanent loss, smart contract exploits, oracle manipulation, and flash loan attacks explained. These advanced risks make due diligence essential — start with crypto lending fundamentals if you're still building your knowledge base. Protect your wallets and approvals by following our security best practices, and check our crypto glossary for definitions of terms like TVL, oracle, and liquidation ratio.

Key Takeaways

• Impermanent loss (IL) applies to LP positions, not lending — but lending carries its own smart contract risk.
• Oracle manipulation: if a price oracle is compromised, attackers can borrow above true value or liquidate unfairly.
• Flash loan attacks: attackers borrow millions, manipulate a pool, profit, and repay — all in one transaction.
• Even audited protocols get exploited — audits reduce risk but don't eliminate it.

Practical Tips

• Stick to protocols with $100M+ TVL and multiple security audits from reputable firms (OpenZeppelin, Trail of Bits).
• Use DeFi insurance protocols (Nexus Mutual, InsurAce) for your largest positions.
• Check rekt.news for a history of protocol exploits — patterns help you avoid similar risk profiles.
