The Vibe: Earning interest by letting others borrow your crypto, or borrowing against your crypto without selling it — all on blockchain, no bank needed.
The Details: In DeFi lending platforms (like Aave, Compound, Morpho), you deposit crypto into a pool and earn interest automatically (paid in the same token or governance tokens). Borrowers put up collateral (usually more than they borrow) to take loans — if their collateral drops too much, it’s liquidated to protect lenders. Rates change in real-time based on supply/demand (high demand = higher rates). You can lend stablecoins for steady yield or volatile assets for higher (but riskier) returns. Everything is transparent and on-chain.
Pro Tip: Start with stablecoins (USDC, USDT) on trusted platforms like Aave for low-risk 3-10% APY. Never borrow more than 50-70% of your collateral to avoid liquidation in crashes. Watch utilization rate — high utilization means better rates but more risk. Always use audited protocols and enable notifications.
