Our verdict on Yearn Finance
7.6/10Yearn suits DeFi users who want automated, compounding yield on assets like ETH, USDC or USDS without managing positions themselves. Its main strength is a long-running vault model with broad integrations across several chains and about $156 million in TVL. The main caveat is that returns are variable and depend on smart contracts and third-party protocols, so losses are possible. Fee levels are not public, so check each vault before depositing.

What is Yearn Finance?
Yearn Finance is a DeFi yield aggregator. Users deposit crypto into vaults that put the funds to work across on-chain lending and liquidity opportunities, with the aim of earning the best risk-adjusted yield. DefiLlama describes it as an aggregator that uses automation to help investors maximize yield farming returns.
DefiLlama shows about $156 million in TVL, up 1.4% over seven days, across Ethereum, Katana, Base, Optimism, Polygon, Arbitrum and Fantom. The homepage reports a higher figure of about $205.8 million deposited in Yearn Vaults, so the two sources differ and depend on how each counts.
The homepage markets Yearn as DeFi's most battle-tested yield aggregator and lists vaults for ETH, USDS, USDC and crvUSD. It also shows integrations with Curve, Alchemix, Origin, Katana, Trueo, Term and Cap. YFI is the project's own token.
How Yearn Finance works
A Yearn vault accepts one asset, such as USDC or ETH, and issues a receipt for the deposit. The vault then allocates those funds to strategies across DeFi, such as lending markets and liquidity pools, and collects the yield they produce.
The yield is reinvested automatically, so the vault compounds without the user having to claim and redeposit by hand. This saves effort and can lower gas costs compared with managing positions individually.
The tradeoff is that the user relies on the vault's strategies and on every protocol those strategies touch. Returns change as market conditions change.

Pros and cons
What we like
- Automated compounding removes the need to manage and reinvest yield by hand.
- Vaults cover major assets including ETH, USDC, USDS and crvUSD.
- Available on several networks, including lower-cost layer-2s such as Base, Optimism and Arbitrum.
- Integrations with established protocols such as Curve and Term.
- Two audits are listed on DefiLlama, and a bug bounty program is advertised.
- Meaningful TVL of about $156 million per DefiLlama.
Watch out for
- Smart-contract risk remains: vaults route funds through several third-party protocols, so a bug or exploit in any of them can cause losses.
- Yields are variable and not guaranteed; public sources give no fixed rates or historical performance figures.
- Fee levels are not stated, so users must check each vault before depositing.
- Only two audits are listed on DefiLlama, and audit scope and dates are not described publicly.
- Strategies can be hard for newcomers to evaluate, since the underlying positions change over time.
- Fantom is listed among supported chains, an older network with a weaker ecosystem than it once had.
Yearn Finance fees
The project does not publish Yearn's fee figures. Vault pages in the app are where users would see each vault's performance and management fees and its current yield before depositing.
Users also pay normal network gas fees to deposit and withdraw, which vary by chain. Layer-2 networks such as Base, Optimism and Arbitrum generally cost less than Ethereum mainnet.
Is Yearn Finance safe?
Yearn's homepage says its contracts are audited by a variety of auditors and that it runs a bug bounty program. DefiLlama lists two audits. The project does not name the auditors, dates or scope, so readers should check the docs for the reports.
Funds in vaults are in smart contracts, not held by a bank or custodian, and users keep control through their wallet. Vault strategies depend on other protocols, which adds layered smart-contract risk. The project does not describe past incidents or regulatory status. Only deposit what you can afford to lose.
