Yield farming is the practice of moving capital between DeFi protocols to maximize the yield you get on your tokens. Instead of leaving your crypto idle, you deposit it in liquidity pools, lending, staking, or more complex strategies to generate passive income.
It's one of DeFi's pillars and why many people enter the space. But also where most money is lost by not understanding the risks well.
What actually generates the yield?
Yield comes from four main sources:
1. Trading fees (LP fees)
When you provide liquidity to a DEX pool (e.g., ETH/USDC on Uniswap), you receive a proportional share of fees traders pay for using that pool. If your position is 0.1% of the pool and $1M in daily fees are generated, you receive ~$1k.
Typical yields: 2-30% APR depending on pool and volatility.
2. Lending interest
You deposit tokens in Aave/Compound/Spark and other users borrow them paying interest. You receive that interest.
Typical yields: 1-8% APR on stablecoins, 0-5% on ETH, much more volatile on altcoins.
3. Staking rewards
You stake tokens (ETH on Lido, SOL on Marinade, etc.) and the network issues new tokens as reward. It's essentially inflation captured by stakers.
Typical yields: 3-7% APR for ETH/SOL/ATOM/etc.
4. Protocol incentives (token emissions)
Many protocols issue their own token as extra reward to attract liquidity. This is called "liquidity mining." It's the origin of the 2020 DeFi summer.
Yields: can be 50-1000%+ but usually temporary and the issued token often devalues fast.
Typical yield farming strategies
Level 1: Conservative
Stablecoins in lending: deposit USDC/USDT/DAI on Aave or Spark. Yield 2-6% APR. Risk: smart contract + stablecoin depeg.
ETH in liquid staking: deposit ETH on Lido and receive stETH. Yield 3-4% APR. More detail in How to stake on Lido.
Level 2: Intermediate
LP in stablecoin-stablecoin pools (e.g., USDC/USDT on Curve): yield 3-10% APR, low impermanent loss risk (both tokens are ~1:1).
LP in ETH/stETH pools (Curve): leverage that stETH ≈ ETH for LP with low IL. Yield 3-8% APR.
Yield-bearing assets as collateral: deposit stETH as collateral on Aave, borrow USDC, convert to more ETH, stake as stETH. "Looping" or "leveraged staking." Amplified yield but more liquidation risk.
Pendle yield tokenization: deposit yield-bearing assets on Pendle and separate principal (PT) from yield (YT). Allows fixing future yields or speculating on variable yield. See Complete PT vs YT guide.
Level 3: Advanced
Concentrated liquidity (Uniswap V3): instead of providing liquidity across the entire price range, you choose a specific range. Much higher yield if price stays in your range. But also more severe IL if it exits. See Concentrated liquidity guide.
Delta-neutral strategies: stake ETH on Lido, open an equivalent leveraged ETH short on perps. The result: capture staking yield + perp funding rate WITHOUT directional ETH exposure. Yield 5-25% APR depending on conditions. More detail in Delta neutral crypto.
Restaking on EigenLayer: deposit stETH/ETH on EigenLayer to secure Actively Validated Services (AVS) in addition to native staking. Additional yield 0.5-3% APR + potential airdrops. See Restaking on EigenLayer.
Level 4: Specialist
Cross-chain farming: opportunities on new chains with low TVL but high incentives (Berachain, Monad, Sui). Temporary yields of 30-100% but high bridge + smart contract risk.
Perp DEX farming: airdrop farming on perpetuals exchanges like Hyperliquid, Pacifica, Lighter. Delta neutral strategies to accumulate points without directional exposure. See Perps 2026 definitive map.
Liquidity bootstrapping pools (LBP): participate in token launches with decreasing price curves. High risk high reward.
APR vs APY: the difference that matters
APR (Annual Percentage Rate): annual rate WITHOUT reinvestment.
APY (Annual Percentage Yield): annual rate WITH compound reinvestment.
If compounding is daily, APY > APR. If continuous compounding, the difference amplifies.
Example: APR 10% becomes APY ~10.47% with daily compounding, ~10.51% with continuous.
Traps:
- Many protocols advertise APY assuming automatic compounding that doesn't apply in reality.
- Very high APRs (>100%) usually shown assuming the issued token holds price — in practice it usually falls fast.
- "Real yield" vs "nominal yield": a 50% APR in a token that loses 60% isn't yield, it's loss.
Yield farming risks
1. Smart contract risk
Protocols can have bugs. Famous cases: Poly Network ($600M), Wormhole ($325M), Ronin ($600M). Auditing and diversifying across audited protocols is most prudent.
2. Impermanent loss (IL)
When you provide liquidity in an AMM, if the price ratio between tokens changes, your position is worth less than if you'd simply held them. It's "impermanent" only if prices return to the original ratio — otherwise, it's real loss.
Severe IL in volatile pairs (ETH/SHIB). Near-zero IL in correlated pairs (ETH/stETH, USDC/USDT).
3. Depeg risk
Stablecoins can break their peg. USDC dropped to $0.87 in March 2023 when Silicon Valley Bank collapsed. UST went to zero in May 2022. If your farm depends on stablecoin, assume the risk.
4. Liquidation risk
If you use leverage (lending + borrowing + re-depositing), an adverse price move can liquidate your position. Keep conservative ratios (LTV <60%).
5. Rug pulls
In new protocols or recently launched tokens, the team can drain funds. The higher the offered APR, the more suspicion needed.
6. Regulatory risk
DeFi operates in gray zone. In the US the SEC has sued protocols. In the EU MiCA doesn't yet fully apply to DeFi but could.
How to start yield farming
Setup
- An EVM wallet: Rabby or MetaMask.
- ETH for gas + capital to deposit. Buy on Binance, Coinbase, Bybit, OKX.
- Consider operating on a Layer 2 to reduce fees.
Recommended first farm
Stablecoin lending on Aave:
- Buy USDC on exchange and withdraw to your wallet (on Arbitrum/Base to save fees).
- Go to app.aave.com.
- Connect wallet, supply USDC.
- Receive aUSDC (token that automatically grows reflecting interest).
- Current yield: ~3-5% APR.
It's the simplest and safest way to start.

How much can I realistically earn?
| Capital | Strategy | Expected annual yield |
|---|---|---|
| $1k-$10k | Stablecoin lending | 3-5% = $30-500 |
| $10k-$100k | Mix of lending + stable LP | 5-10% = $500-10k |
| $100k+ | Delta-neutral + LSD looping | 8-20% = $8k-20k+ |
At retail level with small amounts, yield farming competes with traditional savings accounts in absolute terms. Where it really pays is with substantial capital and knowledge — then you can beat 2-5x what any bank offers you.
FAQ
Is yield farming legal? Doing yield farming individually isn't illegal in most countries. But returns are taxable. More on this in Crypto tax Spain.
How much do I need to start? Technically you can start with $10. But gas fees can eat your return. On Ethereum L1, minimum $5k makes sense. On L2, from $100.
Is it safe? Depends on the protocol. Aave, Lido, Curve, Uniswap have years without exploits and are reasonably safe. New protocols with 100%+ APR: high risk.
Can I lose everything? Yes, in extreme scenarios: protocol hack, massive stablecoin depeg, cascading liquidation in volatile markets. Diversify and don't put everything in one protocol.
How do I report to tax authorities? Each yield harvest (claim) is a taxable event. Yield farming's tax complexity is real. Using Koinly or CoinTracking for tracking is recommended.
Conclusion
Yield farming is one of the best ways to make your crypto capital work, but it's NOT "free money." It requires understanding what you do, managing risks, and accepting that at some point you'll lose something (hack, IL, depeg).
My practical recommendation for beginners: start with stablecoin lending on Aave (safest), get familiar with the flows, and only add complexity when you understand well. The natural progression: lending → stable LP → LSD → modest leverage → advanced strategies.
And never chase impossible APRs. If something offers 500% APR, you'll probably lose the capital before collecting the yield.
