一覽

Yield farming is earning rewards by providing liquidity or lending to DeFi protocols. Farmers strategically allocate capital across pools to maximize APY (annual percentage yield) while managing risk. Engineers build bots automating the process: monitor yields, rebalance automatically, manage gas costs. Senior practitioners earn 15-25% premium because they automate farming at scale. Learning: 6-8 weeks (combines DeFi knowledge, bot development, financial analysis).

什麼是 DeFi Yield Farming

Yield farming is the practice of earning rewards by depositing cryptocurrency into DeFi protocols. Users provide liquidity (ETH/USDC to Uniswap) or lend assets (USDC to AAVE), earning trading fees + farming rewards (protocol tokens). Farmers chase high APY by moving capital between pools, a constant optimization game. Example: Yearn Finance automates this: you deposit USDC → Yearn moves it between AAVE, Curve, Compound chasing best yield → you earn compounded returns.

❓ 常見問題

What's the difference between APY and APR in farming?
APR is simple interest (no compounding). APY compounds interest. Example: 50% APR at daily compound = 64% APY. Farming websites often quote APY (higher number). Always check compounding frequency.
What's impermanent loss?
When you provide liquidity to a pool, prices move, you end up with different token ratio than when you started. If prices move a lot, impermanent loss can exceed farming rewards. Risk when providing liquidity.
How do I reduce gas costs?
Batch transactions (deposit + approve in one tx). Use Layer 2 (Polygon, Arbitrum) with lower fees. Compound less frequently (daily vs. hourly). Gas costs kill small farmers.
Should I farm on stable pairs or volatile?
Stable pairs: lower APY, lower impermanent loss risk. Volatile pairs: higher APY, high impermanent loss risk. Choose based on risk tolerance and market outlook.
How do I automate yield farming?
Write bot: periodically check APYs across pools, calculate optimal allocation, rebalance (unstake from low-yield pool, stake in high-yield). Monitor for opportunities.
