Yield Farming — Trading Wiki

What Yield Farming means

Depositing crypto assets into DeFi protocols to earn rewards through trading fees, token incentives, or interest. High APYs often carry high impermanent loss and smart contract risk.

In depth

Yield farming — also known as liquidity mining — is a decentralized finance (DeFi) strategy where users deposit cryptocurrency assets into smart contract-based protocols to earn returns in the form of trading fees, governance token rewards, interest payments, or a combination of all three. The practice exploded in popularity during 'DeFi Summer' of 2020 when Compound Finance pioneered the distribution of its governance token (COMP) to users who supplied assets to its lending protocol, creating the template for liquidity incentive programs across the ecosystem.

The basic mechanics vary by protocol type. On decentralized exchanges (DEXs) like Uniswap or Curve Finance, yield farmers provide liquidity by depositing token pairs into trading pools and earn a share of trading fees generated by the pool. On lending protocols like Aave or Compound, users deposit assets that other users can borrow, earning interest from borrowers. On yield aggregators like Yearn Finance, smart contracts automatically move user deposits between various protocols to maximize returns through constantly evolving strategies. Advertised APYs (Annual Percentage Yields) in yield farming can range from single digits on established stablecoin pools to thousands of percent on newly launched, speculative protocols.

However, these headline numbers are misleading for several reasons. First, high APYs typically decline rapidly as more capital enters the pool, diluting returns. Second, rewards paid in governance tokens are subject to token price volatility — earning 200% APY in a token that declines 80% results in a net loss. Third, impermanent loss can exceed the earned fees and rewards, making the overall position unprofitable despite the nominally high APY.

Key points

• Depositing crypto into protocols to earn fees, interest, or token rewards
• High APYs often unsustainable and offset by IL and token depreciation
• Smart contract risk means deposited funds can be lost to exploits

Practical tip

Focus on established protocols (Aave, Curve, Uniswap) with stablecoin strategies for sustainable 5-15% APY. Ignore protocols advertising 1000%+ APY — the token rewards will crash and impermanent loss will destroy your principal. The 'real yield' movement prioritizes protocols that distribute actual revenue, not inflated token emissions.

Why it matters when you are learning

Yield farming is DeFi's version of passive income — but 'passive' doesn't mean 'risk-free.' Start small, use established protocols, and never farm with money you can't afford to lose.

Practising Yield Farming on the simulator

Reading about Yield Farming and using it are different skills. Try it once in the simulator on an instrument you already follow, write down beforehand what you expect to happen, and check the journal a day later to see whether it played out that way. Educational simulation only — not financial advice.
