What Is DeFi?

DeFi stands for Decentralized Finance. It refers to financial transactions - lending, borrowing, trading, earning yield - carried out on a blockchain without banks, intermediaries, or regulatory gatekeepers.

In short: code instead of banks, smart contracts instead of intermediaries.

What Can You Do in DeFi?

  • Swap: Exchange one token for another. Protocols like Uniswap and Curve.
  • Lending / Borrowing: Borrow against your crypto as collateral, or lend to earn interest. Protocols like Aave and Compound.
  • Yield farming / Liquidity providing: Provide tokens to liquidity pools and earn rewards.
  • Staking: Lock tokens to support network security and earn rewards in return.
  • NFT markets: Buy and sell digital assets on-chain.

How Is DeFi Different from Traditional Finance?

Traditional finance: opening a bank account requires ID, address, and bank approval. Interest rates are set by the bank. Movement is limited to business hours.

DeFi: an internet connection and a wallet are enough. No identity verification. 24/7 access. Interest rates are determined by supply and demand.

DeFi Risks

  • Smart contract vulnerabilities: A code bug can allow funds to be drained
  • Impermanent loss: A specific risk for liquidity providers
  • Rug pulls: Fraudulent projects drain liquidity and disappear
  • Market volatility: Investments can lose value quickly
