What is DeFi (Decentralized Finance)?
DeFi stands for Decentralized Finance. It recreates traditional banking services using open blockchain code.
Anyone with an internet connection and a crypto wallet can borrow, lend, or trade 24/7 without asking for permission.
Smart contracts replace middlemen like loan officers, bank tellers, and brokers.
Why It Matters in Web3 & Crypto
DeFi gives you complete ownership of your money. It eliminates high bank fees, slow transfer times, and geographic restrictions.
Key Mechanics & Best Practices
- 1Connect a self-custody wallet like MetaMask to a DeFi app.
- 2Deposit tokens to earn interest or borrow against your assets.
- 3Review smart contract audits before depositing funds into any new protocol.
Practical Scenario
Instead of waiting 3 business days for a bank loan, a user deposits $2,000 in ETH into a DeFi lending platform and instantly borrows $1,000 in USDC stablecoins in under 30 seconds.
SECURITY & RISK TIP
Never invest more than you can afford to lose in new DeFi protocols. Always verify that top security firms have audited their code.
