Introduction to DeFi: Lending, Staking & Yield Farming

Introduction to DeFi: Lending, Staking & Yield Farming

DeFi — short for Decentralized Finance — enables permissionless financial services without banks or intermediaries. Users interact directly with smart contracts to earn, borrow, lend, and stake crypto assets autonomously.

How DeFi Works

Smart contracts automate financial agreements. Liquidity provided by users powers trading and lending activity. Users retain full custody of their assets — no bank needed.

DeFi Lending

Users deposit assets into lending pools to earn interest. Borrowers provide collateral and take crypto loans instantly through automated protocols.

Example platforms: Aave, Compound, Venus

Staking

Staking secures Proof-of-Stake blockchains. Users lock tokens to support network integrity in exchange for reward yields — similar to earning dividends.

  • Rewards paid in the native cryptocurrency
  • Lock-up periods vary across networks
  • Lowers volatility by encouraging long-term holding

Yield Farming

Yield farming pushes returns further by incentivizing liquidity providers with additional tokens. High earnings come with risk — especially in volatile markets.

  • Rewards from fees + governance tokens
  • Requires active portfolio monitoring
  • Smart contract risks must be considered
Note: DeFi yields can fluctuate quickly. Rug pulls and contract exploits have caused major user losses — always research platforms before depositing funds.
