In this lesson
- What yield farming is
- Why high APYs signal risk
Key takeaways
- 1Yield farming supplies capital to DeFi for rewards
- 2Rewards may come from emissions, not real revenue
- 3The highest APYs usually carry the highest risk
Lesson summary
Yield farming means supplying assets to DeFi strategies in return for fees, interest, or token rewards.
Mental model
Yield Farming, without the jargon
Yield farming means supplying assets to DeFi strategies in return for fees, interest, or token rewards. The yield is only meaningful if you know who pays it.
Once yield farming is clear, the mechanics in the next section read as common sense rather than trivia.

Mechanics
How to reason about yield farming
Real yield may come from trading fees, borrowing interest, or protocol revenue.
Incentive yield may come from new token emissions.
APY changes as liquidity, demand, token price, and risk change.
Strip it back and the mechanics all point to one fact: yield farming supplies capital to DeFi for rewards.
- Yield farming supplies capital to DeFi for rewards
- Rewards may come from emissions, not real revenue
- The highest APYs usually carry the highest risk
Example
Yield Farming, applied
A pool paying 80% APY in reward tokens can become unattractive if the token price falls faster than rewards accrue.
The value here is the checklist hiding inside the yield farming example, not the specific names or numbers used.
Watch the failure condition in any yield farming example; that is usually where money is won or lost, not in the happy path.
Common mistakes
Common mistakes with yield farming
Chasing the highest APY without identifying the source of yield is one of the fastest ways to take hidden principal risk.
Before acting on yield farming, name the one thing that would have to be true, then confirm it.
With yield farming, the real cost is rarely the first error — it is acting on it with size before checking the assumption.
Risk notes
Before you rely on yield farming
Smart-contract loss, reward token collapse, impermanent loss, oracle failure, and liquidity flight can erase yield.
Write the single yield farming failure mode you would watch for, then size the decision around that rather than the upside.
For yield farming, reversible, small, and verifiable beats large and irreversible whenever the picture is still unclear.
- Separate fee yield from emissions.
- Check contract and oracle risk.
- Estimate exit liquidity.
Practice
Practise yield farming before moving on
Practise Yield Farming on something real — a product page, a chart, a transaction, or a headline tied to DeFi Deep Dive.
Keep your yield farming answers concrete enough that someone could disagree and point to data — that is the bar for "learned".
- Separate fee yield from emissions.
- Check contract and oracle risk.
- Estimate exit liquidity.
Review
Key terms
- DeFi
- Decentralized Finance — permissionless, composable financial services built on smart contracts.
- Impermanent Loss
- The loss a liquidity provider faces when pooled asset prices diverge versus simply holding them.
- Liquidity
- How easily an asset can be bought or sold without moving its price much.
- Oracle
- A service that feeds real-world data (like prices) to smart contracts on-chain.
- Smart Contract
- Self-executing code on a blockchain that runs exactly as written when conditions are met.
