Yield Farming on Ethereum DeFi Platforms

Decentralized finance (DeFi) has exploded in popularity over the last couple of years, with platforms like Compound and Aave leading the way. One of the most attractive features of DeFi is the ability to earn high yields on crypto assets through yield farming. But what exactly is yield farming and how does it work on Ethereum-based DeFi platforms?

What is Yield Farming?

Yield farming refers to generating rewards by providing liquidity to DeFi protocols. When you supply tokens to a lending platform like Compound or Aave, you receive interest on those tokens in the form of governance tokens or other cryptocurrencies. The interest rates can be quite high, sometimes over 100% APY! This makes yield farming an attractive option for crypto investors looking to earn passive income on their holdings.

How Does Yield Farming Work?

The process of yield farming involves lending out your crypto assets on DeFi platforms in exchange for interest. Here are the basic steps:

  1. You deposit tokens into a lending protocol like Compound or Aave as collateral. This allows borrowers to take out loans using your tokens.
  2. In exchange, you receive interest on your tokens in the form of additional tokens. For example, when supplying ETH to Compound you receive cETH tokens which represent your deposit plus accumulated interest.
  3. You can then deposit these earned tokens into other DeFi protocols to earn even more interest. This process of reinvesting interest to maximize yields is known as compounding.
  4. By constantly moving assets around to the highest yielding opportunities, farmers can optimize their returns.

Major Yield Farming Platforms

Some of the most popular yield farming platforms on Ethereum include:

  • Compound - The leading DeFi lending protocol where suppliers earn COMP governance tokens as interest.
  • Aave - Similar to Compound, but offers flash loans and uses the AAVE token for governance.
  • Yearn Finance - An aggregator service that automatically moves funds between protocols to maximize yield. Pays out YFI governance tokens.
  • Curve - A decentralized exchange optimized for stablecoin trading. Suppliers earn CRV tokens.
  • Synthetix - Issuer of synthetic assets (Synths) tied to real world assets. Pays yields in SNX tokens.

Pros and Cons of Yield Farming

Yield farming can be an extremely profitable activity but also comes with some risks:


  • Earn high yields on crypto holdings
  • No need to actively trade or manage funds
  • Access to unique governance tokens


  • High gas fees on Ethereum
  • Smart contract risks like bugs or hacks
  • Volatile token prices and shifting opportunities

Risks and Challenges

While the potential yields are alluring, yield farming does come with a fair share of risks. Some key challenges include:

  • Smart Contract Risks - As yield farming relies on smart contracts, there is always the possibility of exploits or hacks that could lead to lost funds.
  • Impermanent Loss - Providing liquidity typically involves pooling tokens, which is exposed to price volatility between the assets.
  • Gas Fees - Transacting on Ethereum is expensive due to high gas fees. This cuts into farming profits.
  • Regulatory Uncertainty - The regulatory status of DeFi and yield farming remains unclear in many jurisdictions.
  • Tax Complexity - Properly accounting for capital gains, income, and losses across multiple platforms can be extremely challenging.

Tips for Getting Started with Yield Farming

If you're ready to dive into yield farming, here are some tips:

  • Start small to test things out and get comfortable. No need to put your entire stack at risk.
  • Choose reputable protocols with strong track records and developer teams. Newer platforms can be risky.
  • Pay close attention to gas fees. Optimize around times of low network usage.
  • Monitor lending rates closely and be ready to move funds when better opportunities arise.
  • Use trusted platforms like Yearn to automate transfers between protocols.
  • Manage risk by diversifying across multiple yield sources and platforms.

The Future of Yield Farming on Ethereum

Yield farming is still a nascent industry with plenty of room for innovation. Some key developments that could impact future yields:

  • Continued growth in DeFi adoption driving more assets into lending protocols.
  • Introduction of staking derivatives like Lido allowing staked ETH to be used for yield farming.
  • Expansion to layer 2 platforms like Optimism reducing gas fees.
  • New tokenized asset classes like NFTs and real world assets becoming yield bearing.
  • Auto compounding and yield aggregators improving capital efficiency.

The yields likely won't stay sky high forever, but yield farming is here to stay as an innovative way to earn from crypto. As the ecosystem develops, there will be even more opportunities to leverage DeFi and maximize returns. Agility and risk management will be key.

Should You Get Into Yield Farming Today?

Yield farming offers tempting profits but also comes with distinct risks. Here are some key questions to ask yourself:

  • Do I fully understand the protocols I’m using and have a plan to manage risk?
  • Am I comfortable with the technical complexity and time required?
  • What is my timeframe and goals – short-term gains or long-term position?
  • Does yield farming fit with my overall investment strategy and risk tolerance?
  • Am I prepared to pay high gas fees or switch to layer 2 platforms?
  • How will I handle the tax reporting requirements across multiple platforms?

Carefully consider these factors when deciding if yield farming is right for you today. The opportunities are exciting but also require responsibility. Proceed with caution.


Yield farming presents a compelling method for DeFi users to maximize returns on their crypto assets. By providing liquidity to protocols like Compound, Aave, Curve and Synthetix, investors can earn governance tokens, fees, and interest as rewards. However, yield farming is complex and does come with distinct risks related to smart contracts, gas fees, and taxes. Approach yield farming with a solid understanding of the platforms used, have a plan to mitigate risks, and pay close attention to emerging opportunities across the evolving DeFi landscape. Used responsibly as part of a balanced portfolio, yield farming can be a profitable component of a crypto investment strategy.
