DeFi Explained: Banking Without Banks
Decentralized finance rebuilds lending, trading and saving on public blockchains — no intermediaries.
DeFi, short for decentralized finance, recreates financial services using smart contracts instead of banks and brokers. Anyone with a wallet can lend, borrow, trade or earn yield, permissionlessly.
The building blocks
- DEXs let you swap tokens directly from your wallet.
- Lending protocols let you earn interest or borrow against collateral.
- Stablecoins provide a steady unit of account.
The risks
DeFi is transparent and open, but the same code that removes middlemen can be exploited. High advertised yields often hide leverage or token-emission risk, and self-custody means self-responsibility.
