What is Yield Farming?
Yield farming is one of those terms that sounds more complicated than it needs to be. At its core, it’s a way of putting your crypto assets to work in DeFi protocols to earn returns. But like most things in the crypto space, the surface simplicity hides layers of complexity, risk, and nuance that every investor needs to understand before getting involved.
This resource breaks down exactly what yield farming is, how it works, and what you need to be across before committing capital to it.
The Simple Definition
Yield farming refers to the practice of deploying crypto assets into DeFi protocols in exchange for rewards. Those rewards typically come in the form of interest, a share of trading fees, or additional tokens distributed by the protocol.
The term “farming” is an apt analogy. You’re planting your assets into a protocol, letting them work, and harvesting the returns over time. The “yield” is whatever the protocol pays you for providing your capital or liquidity.
In traditional finance, the equivalent would be depositing money in a savings account to earn interest, or investing in a dividend-paying asset. The mechanics in DeFi are different and considerably more complex, but the underlying concept of putting capital to work to generate a return is the same.
How Yield Farming Works
Yield farming takes several different forms depending on the type of protocol involved. The most common mechanisms are liquidity provision, lending and borrowing, and staking.
Liquidity Provision: Decentralised exchanges don’t use traditional order books like their centralised counterparts. Instead, they rely on liquidity pools, which are pools of tokens provided by users that the exchange draws from to facilitate trades.
When you provide liquidity to a decentralised exchange, you deposit a pair of tokens into a liquidity pool in equal value. In return, you receive liquidity provider (LP) tokens that represent your share of the pool. Every time a trade occurs using that pool, a fee is charged, and a portion of that fee is distributed proportionally to all liquidity providers. This is one of the most common forms of yield farming.
Lending and Borrowing: Lending protocols allow you to deposit crypto assets that other users can borrow against collateral. In exchange for lending your assets, you earn interest paid by borrowers. The interest rate typically adjusts dynamically based on supply and demand within the protocol. The more demand there is to borrow a particular asset, the higher the interest rate lenders earn.
Crypto Staking: Some protocols reward users for staking their tokens within the platform. Staking in this context means locking your tokens into the protocol to support its operation or governance, in exchange for token rewards distributed over time. This differs from network-level staking on proof-of-stake blockchains, though the reward mechanism is conceptually similar.
Understanding APY and APR
When evaluating yield farming opportunities, you’ll constantly encounter two figures: APY and APR. Understanding the difference matters.
APR (Annual Percentage Rate) is the simple annual interest rate on your deposited capital, without accounting for compounding. If a protocol offers 20% APR, that means a $10,000 AUD deposit would earn $2,000 AUD over a year at that rate, assuming the rate held constant.
APY (Annual Percentage Yield) accounts for the effect of compounding, where your earned rewards are reinvested to generate additional returns on top of returns. APY will always be equal to or higher than APR on the same underlying rate. The more frequently rewards compound, the larger the gap between APR and APY.
Most DeFi protocols advertise APY rather than APR, and in some cases the figures can look extraordinary, particularly for newer or riskier protocols. This brings us to the risks, which are just as important to understand as the rewards.
The Risks of Yield Farming
Yield farming can generate genuine returns, but it operates in one of the riskiest corners of the crypto space. Every yield farming opportunity carries a specific set of risks that need to be assessed clearly before committing capital.
Smart Contract Risk
Yield farming requires you to deposit your assets directly into smart contracts. If those smart contracts contain a vulnerability or bug, they can be exploited by attackers. DeFi hacks and protocol exploits have resulted in billions of dollars in losses globally. The more complex the protocol and the newer the code, the higher the smart contract risk. Always check whether a protocol’s contracts have been audited by reputable third-party security firms before depositing funds.
Impermanent Loss
This is one of the most misunderstood risks specific to liquidity provision. When you deposit a token pair into a liquidity pool and the price of one token moves significantly relative to the other, you can end up with less total value when you withdraw than if you had simply held the tokens in your wallet. This loss is called “impermanent” because it only becomes realised when you withdraw, and can reverse if prices return to their original ratio. However, in volatile crypto markets, significant and permanent impermanent loss is a very real outcome.
Protocol Risk
Beyond smart contract vulnerabilities, the protocol itself may fail due to poor design, unsustainable economics, or a collapse in demand. Many early DeFi protocols offered extraordinary APY figures that were only sustainable by continuously issuing new tokens as rewards. When demand for those tokens collapsed, so did the yields and the token prices, leaving late participants with heavily devalued holdings.
Liquidity Risk
Some yield farming positions can be difficult to exit quickly, particularly in smaller or newer protocols where liquidity is thin. In a fast-moving market, the inability to withdraw your assets promptly can result in significant losses. Always assess how easily you can exit a position before entering it.
Interacting with DeFi protocols on Ethereum and other networks incurs gas fees on every transaction. Depositing into a protocol, harvesting rewards, and withdrawing all cost gas fees. During periods of network congestion, these fees can be substantial and can eat significantly into your returns, particularly on smaller positions.
Regulatory Risk
DeFi and yield farming exist in a rapidly evolving regulatory environment in Australia and globally. The ATO has made clear that crypto earnings, including yield farming rewards, are subject to tax obligations. Our resources on cryptocurrency tax in Australia and ATO crypto reporting are essential reading for anyone earning yield on their crypto assets.
Mercenary Capital and Unsustainable Yields
One of the most important concepts to understand in yield farming is the problem of mercenary capital. This refers to liquidity that flows into a protocol purely to chase high yields, with no loyalty to the platform or interest in its long-term success.
Protocols that attract mercenary capital through unsustainably high APY figures face a structural problem: the moment yields drop, that capital exits as quickly as it arrived. This can trigger a downward spiral where falling liquidity reduces the protocol’s functionality, which reduces confidence, which accelerates further outflows.
When you see a yield farming opportunity advertising APY figures in the hundreds or thousands of percent, that is an immediate signal to look very carefully at where those yields are coming from. Sustainable yield comes from genuine protocol activity, trading fees, and real demand to borrow. Unsustainable yield typically comes from aggressive token emissions that dilute existing holders over time.
Tokenomics sits at the heart of this analysis. Understanding how a protocol generates and distributes its rewards is fundamental to assessing whether a yield farming opportunity is genuinely attractive or a short-term incentive masking a structurally weak project. Always DYOR and read the project’s whitepaper before committing funds.
Yield Farming vs. Traditional Staking
It’s worth distinguishing yield farming from straightforward crypto staking, as the two are often conflated.
Crypto staking in its purest form involves locking tokens to support a blockchain network’s proof-of-stake consensus mechanism, earning rewards in return. It’s typically simpler, more transparent, and lower risk than yield farming.
Yield farming, by contrast, involves actively deploying assets across DeFi protocols to maximise returns, often across multiple platforms simultaneously. It requires more active management, a deeper understanding of DeFi mechanics, and carries a meaningfully higher risk profile.
Both have their place in a crypto strategy, but they are not the same thing and shouldn’t be treated as interchangeable.
The Role of DAOs in Yield Farming Protocols
Many of the largest yield farming protocols are governed by DAOs, meaning the community of token holders votes on changes to yield parameters, fee structures, and protocol direction. Understanding how a protocol is governed is part of assessing its long-term viability as a yield farming destination.
DAO governance can be a genuine strength, providing transparent, community-driven decision-making. But as covered in our resource on DAOs, it also carries risks around voter apathy and token concentration that can affect how reliably a protocol operates over time.
Is Yield Farming Right for You?
Yield farming is not for everyone, and it’s important to be honest about that.
For investors who are still building their foundational knowledge of cryptocurrency, blockchain technology, and basic investment strategies, yield farming is not the right next step. The complexity, the smart contract risk, and the active management required demand a solid base of knowledge and experience before you put capital to work in this way.
For investors with a genuine understanding of DeFi, tokenomics, and risk management, yield farming can be a meaningful addition to a broader crypto strategy when approached with discipline, proper due diligence, and appropriate position sizing.

Key Takeaways
Yield farming is the practice of deploying crypto assets into DeFi protocols to earn returns through liquidity provision, lending, or staking. APY figures can look compelling but must always be evaluated in the context of where those yields actually come from. Smart contract risk, impermanent loss, protocol risk, gas fees, and regulatory obligations are all real considerations that demand proper attention.
Yield farming rewards those who understand what they’re doing and punishes those who don’t. Build your knowledge base first, size your positions appropriately, and never chase a yield figure without understanding the mechanism behind it.
