Here is a clear explanation of DeFi (Decentralized Finance), the heart of Web3.

💾 What is DeFi?

DeFi = Decentralized Finance = Finance Décentralisée

It is an open financial system, accessible to everyone, without intermediaries (like banks), based on blockchain (especially Ethereum).

🧠 Simple principle

> You can borrow, lend, invest, trade, or make money — just with your crypto wallet, without going through a bank.

đŸ§© Components of DeFi

Lending / Borrowing Aave, Compound, Venus

Staking Lido, Rocket Pool

Yield Farming Yearn Finance, Beefy Finance

Stablecoins DAI (MakerDAO), USDC, USDT

🔑 How does it work?

1. You connect your wallet (e.g., Binance Web3)

2. You interact directly with the protocol (Web3 site)

3. Smart contracts replace banks or brokers

4. You keep full control of your money

đŸ§Ș Practical examples

Lend 1000 USDC on Aave → you earn interest automatically

Provide liquidity on Uniswap → you earn transaction fees

Borrow by putting up 1 ETH as collateral → you receive 800 DAI to use

Stake crypto → you earn rewards
