DeFi (Decentralized Finance)

A financial ecosystem built on blockchain technology that offers traditional financial services like lending, borrowing, and trading without banks or intermediaries.

Decentralized Finance (DeFi) refers to financial applications built on blockchain networks — primarily Ethereum — that replicate traditional banking services without centralized intermediaries. Instead of banks, DeFi uses smart contracts: self-executing code that automatically handles transactions when conditions are met.

Key DeFi Services

  • **Decentralized exchanges (DEXs)**: Trade tokens without a centralized operator (Uniswap, SushiSwap)
  • **Lending/borrowing**: Earn interest or borrow against crypto collateral (Aave, Compound)
  • **Yield farming**: Earn rewards by providing liquidity to protocols
  • **Stablecoins**: Crypto pegged to fiat currencies (USDC, DAI)

Risks of DeFi

DeFi carries significant risks including smart contract bugs, impermanent loss, rug pulls, and regulatory uncertainty. Always research protocols thoroughly and never invest more than you can afford to lose.

FAQ

Is DeFi safe?

DeFi carries higher risks than traditional finance. Smart contract vulnerabilities, rug pulls, and protocol hacks have resulted in billions in losses. Use only well-audited protocols, start with small amounts, and never invest more than you can afford to lose.
