Decentralized Finance (DeFi) is a system of financial applications built on blockchains — primarily Ethereum — that operate without banks or intermediaries. You can lend, borrow, trade, and earn yield using smart contracts. The yields are dramatically higher than traditional finance — and the risks are dramatically higher too.

Ways to Earn in DeFi

Lending protocols: Supply crypto to Aave or Compound. Earn 3–15% APY. Borrowers pay you interest. Risk: smart contract vulnerabilities, liquidation cascades during market crashes. Liquidity providing: Add liquidity to decentralized exchanges (Uniswap, Curve). Earn trading fees. Risk: “impermanent loss” — if the ratio of your two assets changes significantly. Yield farming: Earn governance tokens on top of base yield. Can reach 20–100%+ APY. Risk: extremely high — new protocols can be hacked or rug-pulled.

Starting Safely

Start with established protocols only: Aave, Compound, Curve, Uniswap. Never invest more than you can afford to lose entirely. Use a separate wallet for DeFi activities — don’t connect your main holdings wallet to DeFi protocols. Understand that “yield” in a volatile asset is measured in USD, which can drop faster than yield accumulates.

Earn: $100 learning allocation
Deposit $100 into Aave or Compound to understand how the protocol works before deploying significant capital. The education value of experiencing the interface, transactions, and yield mechanics firsthand is worth the gas fees.
