Yield Farming

Yield farming is the practice of deploying cryptocurrency across DeFi protocols to maximize returns through combinations of trading fees, interest, and token rewards. It emerged in 2020 during DeFi Summer when protocols began distributing governance tokens to liquidity providers, creating explosive APY opportunities that attracted billions in capital. The strategy involves finding the highest-yield opportunities across lending protocols, liquidity pools, and staking mechanisms, then moving capital between them as yields change. Complex strategies involve depositing into protocol A, receiving receipt tokens, using those as collateral in protocol B, borrowing to deposit in protocol C. Each layer adds returns but also compounds risk. The risks are significant: smart contract bugs can drain pools, impermanent loss erodes gains, token rewards inflate and lose value, and gas costs eat into profits on smaller positions. Yield farming APYs are often unsustainable, driven by token emission schedules that decline over time. Early farmers who deployed capital first captured the highest yields; latecomers got diminishing returns. Despite risks, yield farming demonstrated that programmable money could generate complex financial strategies without intermediaries.
