DeFi (Decentralized Finance)

Financial services built on blockchain smart contracts that operate without traditional intermediaries like banks.

DeFi replaces banks, brokers, and exchanges with open-source smart contracts. You can lend, borrow, trade, and earn yield without creating an account or going through identity verification (though regulation is changing this).

USDC is one of the most used assets in DeFi. You can lend it on Aave or Compound to earn interest. You can provide liquidity on Uniswap or Curve. You can use it as collateral to borrow other assets.

DeFi offers higher yields than traditional savings accounts, but with higher risk. Smart contract bugs, impermanent loss, and protocol failures are real possibilities. Start small and stick to established, audited protocols.
