Yearn.finance (YFI) is a prominent decentralized finance (DeFi) ecosystem built on the Ethereum blockchain. It offers a suite of products designed to automate yield generation, lending aggregation, and provide insurance strategies. The protocol is community-driven, managed by independent developers, and governed by holders of its native YFI token.
Initially created by Andre Cronje, the project aimed to solve a key challenge for yield farmers: the manual process of moving capital between lending platforms to chase the best floating interest rates. Yearn’s smart contracts automatically shift funds between major protocols like Aave, Compound, and dYdX based on real-time yield opportunities.
Users can deposit stablecoins such as DAI, USDC, USDT, or TUSD into Yearn’s system. In return, they receive yield-bearing yTokens (like yDAI or yUSDC). These tokens represent a user’s share in a pool and accumulate interest over time.
A major innovation was Yearn’s collaboration with Curve Finance to create yUSD – a liquidity pool consisting of yDAI, yUSDT, yUSDC, and yTUSD. This allowed for more efficient stablecoin yield farming and deeper liquidity.
Following its token launch, Yearn introduced Vaults, a groundbreaking feature that sparked the yield aggregator trend. Vaults automate complex yield farming strategies: they claim rewards, sell them for more underlying assets, and reinvest them to compound returns.
Benefits of using Vaults include automated rebalancing, socialized gas costs (reducing fees for all users), and minimal required DeFi expertise. They offer a passive investment vehicle similar to a crypto hedge fund, focused on growing a user’s initial deposit through optimized yield strategies.
Understanding YFI and WETH Trading Pairs
YFI is often paired with WETH (Wrapped Ethereum) on decentralized exchanges like SushiSwap. WETH is an ERC-20 compatible version of Ethereum’s native coin, ETH, which is necessary for trading on many DeFi platforms.
Liquidity pools containing YFI and WETH allow users to swap between the two assets efficiently. These pools are fundamental to DeFi trading, providing the market depth needed for large transactions with minimal slippage.
When you provide liquidity to a YFI/WETH pool, you earn a share of the trading fees generated by the pair. This is a popular way to earn passive income on crypto holdings beyond simple yield farming.

How Does Yearn.finance Generate Yield?
Yearn’s core strength lies in its automated yield-generation strategies. The system continuously scans the DeFi landscape for the most profitable opportunities across lending, liquidity provision, and other incentive programs.
When you deposit funds into a Yearn product, its smart contracts automatically allocate your capital to the strategy currently offering the highest risk-adjusted returns. This happens seamlessly in the background without any required action from the user.
The system also handles the complex process of compounding. Instead of just earning rewards, it automatically sells those rewards for more of the underlying asset and reinvests them. This accelerates returns through the power of compounding interest.
Key Benefits of Using Yearn.finance Vaults
- Automation: Executes and manages complex DeFi strategies without manual intervention.
- Gas Efficiency: Bundles transactions for many users, significantly reducing individual gas fees.
- Accessibility: Opens up advanced yield farming strategies to users regardless of their technical expertise.
- Diversification: Funds are often deployed across multiple protocols to mitigate risk and maximize returns.
Frequently Asked Questions
What is the difference between YFI and yTokens?
YFI is the governance token of the Yearn.finance ecosystem, giving holders voting rights. yTokens (like yDAI) are interest-bearing tokens you receive when you deposit a stablecoin into a Yearn vault; they increase in value as yield is earned.
Is providing liquidity to a YFI/WETH pool risky?
Yes, like all decentralized finance activities, it carries risk. The primary risk is impermanent loss, which occurs when the price of your deposited assets changes significantly compared to when you deposited them. Always understand the risks before providing liquidity.
How do I start using Yearn.finance?
To get started, you need an Ethereum wallet like MetaMask, funded with ETH for gas fees and the assets you wish to deposit. Then, you can connect to the Yearn.finance app and choose a vault or product to invest in.
Are Yearn vaults safe to use?
While Yearn is a well-audited and established protocol, all DeFi smart contracts carry inherent smart contract risk and the potential for bugs or exploits. It is considered one of the more reputable platforms, but users should never invest more than they are willing to lose.
Can I track my earnings on Yearn.finance?
Yes, the Yearn.finance interface displays your deposited balance and the accumulated earnings for each vault. Your yTokens themselves also appreciate in value relative to the underlying asset, reflecting your earned yield.
What blockchain is Yearn.finance built on?
Yearn.finance is primarily built on the Ethereum blockchain. This means all interactions with the protocol require ETH to pay for transaction fees (gas).
