What Is DeFi? The Complete Beginner's Guide
DeFi = financial services run by code, without banks. Here is everything you need to know.
The Core Idea
Smart contracts on Ethereum replace intermediaries. When conditions are met, the code executes automatically. No approval, no bank, no middleman.
The Main Protocols
- Lending (Aave, Compound): Deposit → earn yield. Borrow against collateral.
- DEX (Uniswap): Trade tokens peer-to-peer. You keep custody.
- Stablecoins (DAI, USDC): USD-pegged crypto used across DeFi.
- Yield Farming: Provide liquidity, earn protocol tokens. High risk.
DeFi in Numbers (2026)
- Total Value Locked: ~$80 billion (DeFiLlama)
- Ethereum: ~60% of all DeFi activity
- Largest protocol: Lido (liquid staking)
The Risks
- Smart contract exploits: $5B+ lost since 2020
- Liquidation: borrow too much → collateral auto-sold
- Regulatory: MiCA (EU) enforced, SEC active in US
- Rug pulls: anonymous teams drain funds
