πΎ Yield Farming Yield Farming
Instead of letting your crypto sit idle in a wallet, you deposit it into a DeFi app (usually a liquidity pool) so it earns extra crypto: trading fees, interest, and sometimes bonus tokens.
π¦ The simple version β like renting out your money
Think of a high-yield savings account, or being a landlord: instead of cash sitting idle, you let other people use your asset and you collect a cut. Yield farming is the crypto version. You hand your tokens to a DeFi app, other people trade or borrow against them, and you get paid for supplying that money. The big difference from a bank: the rate floats constantly, nothing is insured, and your deposit itself can shrink.
π§ How it actually works
You deposit crypto (often a pair of tokens like ETH and USDC) into a smart contract called a liquidity pool. In return you receive LP tokens (liquidity provider tokens) that represent your slice of that pool. When other people trade against the pool or borrow from it, the fees and interest they pay get split among LP holders, in proportion to each holder's share.
π Advanced farmers sometimes take those LP tokens and stake them again on another app to stack a second layer of rewards. Beginners should skip this β each extra layer adds another way for things to break.
π° Where do the rewards come from?
| Source | How it works |
|---|---|
| π§Ύ Trading & lending fees | Every swap or loan in the pool pays a small fee that flows to liquidity providers |
| π Bonus governance tokens | Many apps hand out their own token to attract deposits β this is called "liquidity mining" |
| π Yield-bearing tokens | Some tokens you receive slowly accrue value over time, even while you hold them |
π Returns are quoted as APR (no compounding) or APY (with compounding). Both are projections, not guarantees β they swing as money enters and leaves the pool.
π± Where it came from
Yield farming took off in June 2020, when Compound launched its COMP token and started handing it out to people who lent and borrowed on the platform. That "liquidity mining" model lit a fire: total value locked in DeFi jumped from roughly $500M to about $10B that year. The stretch of frenzy that followed is now called "DeFi Summer."
π¨ Things beginners should know
- π Impermanent loss β If the two pooled tokens drift apart in price, you can end up with less value than if you'd just held them
- π Smart-contract risk β A bug or exploit in the app's code can drain the pool, and there's no bank to refund you
- π» Falling rates β A juicy APY usually shrinks fast once more money piles into the same pool
- π« Beware "guaranteed" yields β Fixed, sky-high returns with "no risk" are almost always a scam
β FAQ
- Is a high advertised APY guaranteed free money?
- No. A headline APY is a projection, not a promise. The rate usually drops fast as more money pours into the pool, and your real return can be eaten by impermanent loss, smart-contract bugs, or a token losing its value. Treat any 'guaranteed high yield' as a warning sign.
- Is yield farming the same as staking?
- No. Staking locks up coins to help secure a blockchain. Yield farming supplies liquidity to a DeFi app so others can trade or borrow. Yield farming carries impermanent-loss risk that plain staking does not, because you are holding a pair of tokens whose prices can drift apart.
- What is impermanent loss?
- When the two tokens you deposited change in price relative to each other, the pool rebalances your share, and you can end up with less value than if you had simply held both tokens. The fees you earn may or may not make up the difference. It only becomes a real, permanent loss when you withdraw while the prices are still skewed.
