What Is DeFi? A Beginner Guide
What DeFi means
Decentralised finance (DeFi) recreates financial services — trading, lending, borrowing, earning yield — using smart contracts on public blockchains, without a central intermediary. You interact directly from a self-custody wallet.
Core building blocks
DEXs like Uniswap let you swap tokens non-custodially; lending protocols let you earn interest or borrow against collateral; liquidity pools and staking offer yield in exchange for providing capital and taking on risk.
The real risks
DeFi carries smart-contract bugs, exploits, impermanent loss, scam tokens and liquidation risk on leverage. There is no customer support or chargebacks — mistakes and approvals are often irreversible.
How to start safely
Begin with small amounts on established protocols, research using neutral analytics like DeFiLlama, track positions with a read-only tool like DeBank, and never approve contracts you do not understand.
