Yield farming is a decentralized finance (DeFi) strategy where users provide liquidity to protocols in exchange for rewards, typically in the form of interest, fees, or new tokens. By leveraging smart contracts, yield farmers can maximize returns on their crypto assets, but must also navigate risks like impermanent loss, volatility, and protocol vulnerabilities.
How does yield farming work?
- Deposit: Users supply crypto assets (e.g., USDC, ETH, DAI) to liquidity pools or lending protocols.
- Liquidity provision: Assets are used by others for trading, borrowing, or other DeFi activities.
- Rewards: Providers earn a share of fees, interest, or protocol tokens (e.g., UNI, SUSHI, COMP).
- Auto-compounding: Some platforms reinvest rewards to maximize APY.
- Withdrawal: Users can withdraw their assets and earned rewards at any time.
Yield farming vs staking vs lending
| Feature | Yield Farming | Staking | Lending |
|---|---|---|---|
| Mechanism | Provide liquidity to pools | Lock tokens to secure network | Loan assets to borrowers |
| Rewards | Fees, tokens, APY | Block rewards, APY | Interest, APY |
| Risk | Impermanent loss, smart contract | Slashing, lockup | Default, protocol |
| Flexibility | High (withdraw anytime) | Medium (lockup period) | High (withdraw anytime) |
| Examples | Uniswap, SushiSwap | Ethereum 2.0, Solana | Compound, Aave |
