Yield Farming

Strategy of maximizing returns by harnessing several DeFi protocols

Definition

Yield farming means routing capital across DeFi protocols to capture incentives on top of whatever the underlying position earns. Every farm yield decomposes into two parts that behave completely differently. The base layer is real revenue: trading fees on an AMM, interest paid by borrowers on a money market, a share of protocol income. The incentive layer is token emissions, which are new supply issued to attract capital, paid ultimately by dilution rather than by anyone's income. A 120% APR that is 5 points base and 115 points emissions is a bet on the emission token's price, not a yield. The farmer's real job is separating the two, estimating how long the emission lasts, and knowing what the exit costs in gas, price impact and impermanent loss.

Farming is chasing incentives across protocols. Part of the yield is real income from fees or interest; the rest is a token being printed, and printing is paid for by whoever holds it last.

Example

The stETH/ETH pool on Curve earns roughly 2% from trading fees, which is real revenue paid by swappers. CRV emissions add several points on top, boosted up to 2.5x if you hold veCRV, and third parties may add bribes through vote markets. Now contrast a new farm advertising 120% APR where 115 points come from a token with $2M of total liquidity emitting $500,000 of value per week. The APR is quoted at the current token price and assumes you can sell what you earn: at that emission rate against that liquidity, the first serious harvest moves the price and the headline number is fiction within days.

How it works

Deposit into a pool or market to earn base yield, then stake the receipt token to collect emissions on top. Rewards are harvested, sold or compounded, and the position carries the underlying's risk plus every contract layer you stacked.

Why it matters

It is the main way capital gets allocated in DeFi, and the main way retail loses money while watching a number go up. Distinguishing revenue from dilution is the whole skill.

What to check

Break the APY into base yield and emissions. Compare weekly emission value with the reward token's liquidity, model impermanent loss for the pair, count the contract layers, and price the round trip in gas before entering.

Risks to Consider

Quoted APR assumes a constant reward token price while your own selling is part of what pushes it down
Impermanent loss on the underlying LP position can exceed the incentives, particularly on volatile or correlated-until-they-are-not pairs
Each layer adds contract risk: pool, gauge, auto-compounder and wrapper each have to hold for the position to be safe
Gas and harvest costs make small positions structurally unprofitable, and the exit is more expensive than the entry

Common Questions

Is the advertised APY real?

Split it. Fees, interest and revenue shares are real and roughly persistent. Emissions are real only for as long as you can sell the token at something near the price used in the quote, and the quote almost always assumes no price decline and full compounding. A quick test: divide the weekly emission value by the reward token's liquidity. If you are emitting a quarter of the token's liquidity every week, the headline APY is arithmetic, not income.

What actually kills farm returns?

In order: the reward token falling faster than you can harvest, impermanent loss on the LP leg, and fixed costs. A pair that diverges 50% costs an x*y=k LP around 2% against simply holding, which is survivable, but a reward token down 80% over the same period is not. Gas is the silent killer on small positions, where entering, compounding weekly and exiting can consume a double-digit percentage of the principal.

How should I size and exit a farm position?

Size it so that a total loss of the position is acceptable, because layered contract risk is real and correlated. Then decide the exit rule before entering: a target date, an emission cut, a TVL threshold, or simply harvesting and selling rewards continuously rather than accumulating them. Farmers who compound the reward token back into the farm are doubling down on the one part of the yield that is not revenue.
