What is yield farming and how does it work?
Yield farming is a DeFi strategy that allows users to earn rewards by providing liquidity to decentralized exchanges and lending protocols.
Rewards are typically earned through transaction fees and governance tokens, which are distributed to liquidity providers based on their share of the pool.
Yield farming carries risks such as impermanent loss, smart contract vulnerabilities and rug pulls, making due diligence and risk management essential.
Different crypto yield farming strategies exist, including liquidity provision, staking LP tokens and using automated yield aggregators to optimize returns.
Intro to yield farming 🔍
Yield farming is a strategy that allows crypto holders to earn rewards by providing liquidity to decentralized finance (DeFi) protocols. It plays a key role in the DeFi ecosystem, enabling efficient token swaps while offering opportunities for passive income.
Like many aspects of crypto, yield farming comes with unique benefits and risks that traders should consider before getting started. Understanding liquidity pools, reward mechanisms and risk management is essential for navigating the space effectively.
In this guide, we’ll explore what yield farming is, how it works and the strategies commonly used by those seeking to optimize their returns.
How does yield farming work? ⚙️
Yield farming allows crypto holders to provide liquidity to DeFi protocols in exchange for rewards, with the goal of generating passive income. Contributing assets to decentralized platforms helps facilitate token exchanges and other financial activities within the ecosystem.
These protocols use automated market makers (AMMs) like Uniswap and SushiSwap, which operate liquidity pools for token swaps without relying on traditional order books.
Yield farmers contribute cryptocurrencies, such as Ethereum and stablecoins, to these pools, allowing DeFi users to swap tokens seamlessly.
In exchange, liquidity providers (LPs) receive LP tokens, which represent their proportional share of the pool. The protocol charges a fee whenever someone swaps assets within the pool. These fees are then distributed as rewards to LP token holders, with each holder receiving a share based on their contribution to the pool.
Some platforms also distribute native governance tokens like CRV or COMP as additional rewards, incentivizing participation and decentralization.
The process of yield farming involves several steps. Here is a simplified breakdown of the mechanics:
- Select a platform: Choose a DeFi platform that supports yield farming and offers the desired tokens for liquidity provision.
- Provide liquidity: Deposit a pair of crypto tokens into a liquidity pool.
- Receive LP tokens: Upon depositing, you'll receive LP tokens representing your share of the pool. You can stake these tokens on other platforms to generate a secondary yield.
- Staking and yielding: Stake your LP tokens on the same platform or another one offering yield farming. This strategy can yield staking rewards in the form of additional tokens. Yield farming platforms often display rates as annual percentage yield (APY).
- Claim and reinvest: Periodically, yield farmers claim rewards, which are credited to your connected Web3 wallet, and reinvest them to maximize returns.
Certain platforms allow LPs to stake their LP tokens, generating secondary yield from their initial farming strategy. To collect earned yields, LP holders must unstake and redeem their tokens. Rewards are automatically credited to their connected crypto wallet.
Successful yield farming requires ongoing management, as rewards, risks and market conditions can change rapidly.

Popular yield farming platforms 🏆
While numerous platforms support yield farming, a few stand out due to their strong adoption, unique features and innovative reward structures.
Aave (AAVE): The decentralized lending protocol
Aave is a decentralized, non-custodial liquidity protocol that allows users to lend, borrow and earn interest on crypto assets. It offers flash loans, stable and variable interest rates, and support for multiple blockchain networks.
- Unique differentiator: Aave introduced flash loans, which allow users to borrow funds without collateral, provided the loan is repaid within a single transaction.
- Cryptocurrency utility: The AAVE token is used for staking, governance and fee discounts, with holders voting on protocol changes.
- Yield farming benefit: Yield farmers can supply liquidity to Aave pools and earn interest, while some strategies involve borrowing assets to reinvest in higher-yield opportunities.
Compound (COMP): Algorithmic interest rates
Compound is a decentralized lending protocol where users can supply assets to liquidity pools and earn interest based on algorithmically adjusted rates. It pioneered the liquidity mining model, distributing COMP governance tokens to users who interact with the platform.
- Unique differentiator: Interest rates are set by an algorithm that dynamically adjusts supply and demand for each asset.
- Cryptocurrency utility: The COMP token grants governance rights, allowing holders to propose and vote on protocol changes.
- Yield farming benefit: Farmers can earn COMP tokens in addition to interest rewards by supplying or borrowing assets.
Curve DAO (CRV): Stablecoin liquidity optimization
Curve is a decentralized exchange (DEX) specialized in stablecoin trading and low-slippage swaps. Its AMM model optimizes for efficiency, reducing impermanent loss and maximizing returns for liquidity providers.
- Unique differentiator: Curve’s pools focus on low-volatility assets like stablecoins and wrapped tokens, minimizing risk while ensuring deep liquidity.
- Cryptocurrency utility: The CRV token is used for governance and staking, with holders earning additional rewards for locking tokens in the Curve DAO.
- Yield farming benefit: Liquidity providers earn trading fees and CRV incentives, with the ability to boost yields by locking CRV for veCRV (vote-escrowed CRV).
Uniswap (UNI): The leading decentralized exchange
Uniswap is one of the most widely used AMMs, allowing users to swap crypto assets without intermediaries. It operates on the constant product formula, enabling anyone to provide liquidity and earn a share of trading fees.
- Unique differentiator: Uniswap pioneered the AMM model, allowing permissionless token swaps without order books.
- Cryptocurrency utility: The UNI token is used for governance, giving holders a say in protocol upgrades and fee distributions.
- Yield farming benefit: Liquidity providers earn a share of swap fees and can stake LP tokens for additional yield opportunities.
Yearn.finance (YFI): The yield aggregator
Yearn.finance is a yield aggregator that helps users maximize returns by automatically allocating funds to the most profitable DeFi protocols. It simplifies yield farming by moving assets between lending pools and liquidity mining opportunities.
- Unique differentiator: Yearn.finance automates yield farming through smart contract-based vaults, reducing the need for manual management.

What are the benefits and risks of yield farming? ⚖️
While yield farming presents numerous opportunities, it's important to weigh them against the inherent risks to make informed decisions.
Benefits of yield farming
Yield farming presents an attractive opportunity for crypto holders to earn rewards. Participants contribute liquidity to DeFi platforms and, in return, can earn rewards while supporting DeFi growth.
- Earn rewards: Yield farming allows you to earn rewards for contributing liquidity to DeFi platforms. The rewards are often paid in the form of transaction fees and governance tokens.
- Access to diverse rewards: Some platforms offer additional incentives, such as governance tokens (like CRV or COMP), to encourage liquidity provision and decentralize control of the platform.
- Opportunities to grow capital: Through yield farming, you can grow your crypto holdings by earning additional tokens. By reinvesting your rewards, you have the potential to significantly increase your assets over time.
Risks of yield farming
While yield farming can offer high rewards, it’s important to consider the risks involved. These include impermanent loss, smart contract vulnerabilities and the potential for fraudulent projects.
- Impermanent loss: This occurs when the value of assets deposited in a liquidity pool fluctuates significantly compared to its current market price. This can lead to lower returns than if the liquidity provider had simply held onto their crypto.
- Smart contract exploits: Smart contracts are the backbone of DeFi, but they can contain bugs or vulnerabilities that attackers may exploit. This can lead to loss of funds or manipulation of rewards.
- Rug pulls: Some fraudulent developers create fake projects to attract liquidity, only to pull the rug and steal the funds once the pool has grown large enough. This makes research and caution essential when choosing where to invest.
Yield farming vs. crypto staking 🧐
While yield farming and crypto staking both allow users to earn rewards on their crypto holdings, they work in different ways and come with distinct risks and benefits.
- Yield farming involves providing liquidity to decentralized exchanges (DEXs) or lending protocols, earning rewards from trading fees and governance token incentives. It often requires active management to optimize returns.
- Crypto staking secures proof-of-stake (PoS) blockchains. Users lock up their crypto in a staking smart contract to help validate transactions and earn staking rewards on a particular blockchain network.
Key differences between the two include:
- Management: Staking can be considered more passive, requiring little ongoing action after your crypto is staked. Yield farming needs active management to optimize returns, especially when rebalancing positions or identifying new platforms to earn yield on.
- Rewards: Yield farming typically offers higher rewards, especially from governance tokens and fees, but oftentimes come with a higher risk of loss. Staking rewards may be more predictable and consistent.
For those interested in staking instead of (or alongside) yield farming, staking may offer lower risks and more predictable returns, while yield farming has higher reward potential but greater risks like impermanent loss.
How are yield farming returns calculated? 📊
Yield farming returns are typically measured using annual percentage yield (APY) and annual percentage rate (APR). APY includes compounded earnings, reflecting how reinvested rewards increase returns over time, while APR represents simple interest without factoring in compounding.
Several factors influence actual returns, including trading volume, liquidity incentives, impermanent loss and platform fees. Higher trading activity in a liquidity pool generates more fees for liquidity providers, while some platforms boost rewards by distributing governance tokens like CRV or COMP.
To estimate potential earnings, many DeFi users rely on yield calculators that track APY, fees and reward projections.
