✦ Key Insight

Understanding Reserve Factor helps users evaluate DeFi yield, leverage, liquidity, borrowing risk, and protocol incentives without relying only on headline APY or token rewards.

✕ Common Misconceptions

Do not assume Reserve Factor works the same across protocols. Check contract design, liquidation rules, oracle dependencies, fees, and smart-contract risk before committing funds.
