Yield farming lets you earn crypto rewards by supplying tokens to decentralized finance (DeFi) protocols. You can generate returns through lending interest, trading fees and token incentives, but your earnings aren’t guaranteed, and losses can outweigh the yield you collect. The right strategy depends on your assets, fees, risk tolerance and how easily you need to access your funds.

Yield farming is a way to earn returns on cryptocurrency by depositing or supplying assets to decentralized finance (DeFi) protocols. Depending on the strategy, you can collect lending interest, a share of trading fees or additional token rewards. Returns vary with market conditions, protocol activity and incentive programs, and your deposited assets can lose value.
Yield farming differs from other ways of earning or holding crypto:
| Activity | How returns are generated | Primary risk |
|---|---|---|
| Yield farming | Lending interest, trading fees, token incentives or automated strategies | Smart contract failures, market losses and changing yields |
| Staking | Rewards for participating in a proof-of-stake blockchain, directly or through a staking provider | Token-price volatility, slashing and provider risk |
| Crypto lending | Interest paid by borrowers, through a centralized service or DeFi protocol | Borrower, platform or smart contract risk |
| Holding crypto | No yield unless the asset has a separate reward mechanism | The asset’s market price falls |
Yield farming and crypto lending overlap: lending can be one yield farming strategy. Likewise, some staking and liquid-staking positions can be used in more complex DeFi strategies.
The main distinction is that yield farming often involves actively choosing where to deploy assets to earn returns, sometimes across multiple protocols.
Yield farming uses DeFi applications and smart contracts to allocate crypto to activities that generate income.
There are a few important concepts to understand:
For example, supplying USDC to a lending market may earn interest as borrowers use the available funds. Depositing a token pair into a decentralized exchange may earn trading fees, but you also take on the risks associated with holding both assets in a pool.
Yield farming platforms may advertise returns as either an annual percentage rate (APR) or an annual percentage yield (APY).
| Measure | What it means |
|---|---|
| APR | The annualized simple rate, without compounding. |
| APY | The annualized rate that accounts for compounding at the assumed frequency. |
For example, a 10% APR compounded monthly produces an APY of approximately 10.47%, assuming the rate remains constant and ignoring fees.
Neither figure guarantees what you’ll earn. DeFi rates can change with borrowing demand, trading activity, liquidity and token incentives. An advertised APY may also include rewards paid in a volatile token, so the dollar value of your returns can fall even if the number of tokens you earn stays the same.
Yield farming strategies differ in how they generate returns, how much work they require and what can go wrong. These are the main approaches to compare.
Supply crypto to a lending protocol and earn interest as borrowers use the funds. Rates generally change with borrowing demand and pool utilization. This is often simpler than managing a liquidity position, but you still face smart contract, liquidity and underlying-asset risks.
Deposit assets into a trading pool to earn a share of transaction fees and, in some pools, additional incentives. You may need to supply two assets and manage the price range of your position. Price changes can leave you with a less favorable mix of assets than simply holding them.
Supply stablecoins such as USDC and USDT to a pool that facilitates trading between assets intended to maintain relatively stable values. Returns can come from trading fees and token incentives. A stablecoin can lose its peg, however, and two stablecoins may have different collateral, issuer and liquidity risks.
Deposit assets into a vault that deploys funds through predefined strategies. Some vaults collect and reinvest earnings automatically, helping reduce manual management and potentially sharing transaction costs across depositors. You still rely on the vault’s smart contracts, strategy design and underlying protocols.
More experienced users may borrow to increase a yield farming position or use protocols such as Pendle to trade principal and future yield separately. These approaches can create exposure to changing interest rates, leverage, token prices and maturity dates. Leveraged positions can be liquidated, while purchased yield tokens can lose value if realized yield falls short of expectations.
Which strategy is best? There is no universal winner. Lending markets may be easier to understand, stablecoin pools can reduce direct exposure to broad crypto price movements, and automated vaults can simplify management. None eliminates the possibility of losing money.
These five protocols are useful starting points for researching different yield farming approaches. They are not ranked recommendations, and their inclusion does not guarantee that every product, asset or network is available to every US user.
Compare the specific pool, market or vault rather than relying on a protocol’s name or advertised APY.
| Protocol | Primary use case | How yield is generated | Main risk to investigate |
|---|---|---|---|
| Aave | Crypto lending and borrowing | Interest paid by borrowers | Smart contract, liquidity and collateral risks |
| Uniswap | Token trading and liquidity provision | Trading fees; incentives where offered | Impermanent loss and concentrated-liquidity risk |
| Curve Finance | Stablecoin and other token liquidity pools | Trading fees and applicable incentives | Depegs, pool composition and reward-token exposure |
| Yearn Finance | Automated yield vaults | Strategies that deploy and reinvest assets across DeFi | Vault, strategy and underlying protocol risks |
| Pendle | Trading tokenized principal and yield | Yield-bearing assets, fixed-yield positions and yield-token trading | Maturity, market pricing and changing underlying yields |
Official documentation confirms Aave’s interest-bearing lending markets, Uniswap’s liquidity positions, Curve’s fee and incentive mechanisms, Yearn’s automated vault strategies and Pendle’s principal-and-yield tokenization.
Don’t compare platforms using APY alone. A lower advertised yield from a strategy you understand may be more appropriate than a higher yield that depends on leverage, volatile rewards or several interacting protocols.
Your earnings depend on the amount you deposit, the strategy’s realized yield, fees, asset prices and how long you stay invested. A high advertised APY can be misleading if the yield relies on temporary incentives or exposes you to substantial market risk.
Suppose you deposit $1,000 into a hypothetical yield farming strategy advertising an 8% APY.
The example assumes the 8% APY is maintained for the full year, the $20 in costs is additional, and there are no other gains or losses. Actual returns may differ.
This example illustrates why costs matter. Your actual result could be worse if the yield falls, the assets lose value or the strategy incurs additional expenses.
A projected APY is not the same as a realized return. To evaluate performance, compare the dollar value of your assets before and after the strategy, account for deposits and withdrawals, and subtract all relevant costs.
Yield farming can generate returns, but you could lose some or all of your deposit.
You don’t need to use a complicated strategy to begin exploring DeFi. Start by understanding the product and its risks before committing funds.
Yield farming may suit crypto holders who want to put idle assets to work and understand the risks of interacting with DeFi protocols. It can also appeal to more experienced users who want to manage liquidity positions or automate yield-generating strategies.
However, it isn’t a guaranteed source of passive income.
Simple lending strategies may be easier to understand than liquidity provision, leveraged farming or yield tokenization. Even so, a simpler strategy is not automatically safe.
Compare expected net returns rather than headline APYs. A lower-yield strategy with understandable risks and reasonable costs may be more suitable than a high-yield opportunity whose returns depend on volatile rewards or complex financial structures.
If yield farming feels too high risk for your goals, consider other ways to earn passive income with crypto, including staking coins and cashback credit cards with crypto rewards.
