Yield Farming

Yield farming is the practice of moving cryptocurrency assets between different DeFi protocols to maximize the return earned on those assets. A yield farmer is constantly hunting for the highest available interest rates, bonus token rewards, and fee income across dozens of protocols, reinvesting profits to compound returns and shifting funds as better opportunities emerge. The goal is to put every dollar of crypto to work as productively as possible at all times.

The term comes from the agricultural metaphor of planting your capital in fertile ground and harvesting returns. Just as a skilled farmer might rotate crops across multiple fields to maximize output from the land, a yield farmer rotates capital across protocols to maximize return on investment. The strategies range from simple (deposit stablecoin into a lending protocol to earn interest) to extraordinarily complex (borrow against deposited collateral, use borrowed funds to provide liquidity, stake the LP tokens to earn governance tokens, sell those tokens and repeat).

Yield farming exploded in popularity during DeFi Summer (2020) when protocols began offering massive token rewards to attract liquidity. Returns in the thousands of percentage points briefly appeared, though most required accepting significant risks: smart contract bugs, protocol hacks, token value collapse, impermanent loss, and the complexity of managing many positions at once. Today, yields are more modest and more sophisticated farmers use automation tools and aggregators to manage their strategies.

Example: A savings-minded person notices that Bank A offers 2% annual interest, but if they deposit at Bank B they get 3% plus $50 in store vouchers, and if they also enroll in Bank B’s referral program they get another $20. They keep an eye on all three banks and move their money each month to wherever the total reward is highest, carefully tracking every bonus and rate change. That is yield farming — just with smart contracts instead of banks.
