Where the yield comes from
Yield has two sources. The first is organic: the swap fees a liquidity pool pays its providers. The second is incentive-based: protocols mint their own governance tokens and hand them to liquidity providers to bootstrap depth. This second source is what “liquidity mining” usually refers to.
Why APYs can be misleading
A 200% APY quoted in a protocol’s own token is only worth 200% if that token holds its value. As rewards are farmed and sold, emission-heavy tokens often fall faster than the yield accrues, leaving farmers with a large number of nearly worthless tokens. Always separate the fee yield from the incentive yield, and price the incentive in what it is actually worth.
- Fee APR → real, paid by traders, sustainable.
- Reward APR → depends entirely on the reward token holding value.
- Impermanent loss → can quietly erase the yield if the pair diverges.
The risks under the returns
Beyond token dilution, yield farming stacks risks: smart-contract bugs, impermanent loss, and pools that look deep until incentives end and liquidity flees. The highest advertised yields usually carry the highest of these risks.
Frequently asked questions
What is the difference between yield farming and liquidity mining?
Liquidity mining specifically means earning a protocol’s native token for providing liquidity. Yield farming is the broader practice of moving capital between DeFi protocols to maximise total return, of which liquidity mining is one strategy.
Is yield farming safe?
It carries real risks: smart-contract exploits, impermanent loss, and reward tokens losing value. Sustainable fee yield from deep, high-volume pools is lower-risk than chasing triple-digit incentive APYs on new protocols.
How do I judge a farm’s real yield?
Split the APY into fee income (paid by traders, durable) and token incentives (only as valuable as the token). Then weigh impermanent-loss risk for the pair. A modest, fee-driven yield often beats a huge, emission-driven one.
