Editorial policyUse Yearn at yearn.fi when you want a vault to allocate for you and you accept strategy plus underlying protocol risk. Skip Yearn if you wanted to pick Aave or Curve yourself, or you thought YFI was a dividend. Educational research, not financial advice.
Yearn runs strategy vaults that allocate into other protocols. Verdict-first guide on when to pick Aave yourself and Yearn’s role co-building Resupply with Convex.
Market context
DeFiLlamaSkip Yearn if you cannot name what the vault deposits into, you wanted Convex gauge boost only, or you have never used a simple lending supply. Vault APYs mix fees and sometimes emissions. Yearn co-built Resupply with Convex — that is a separate app.

Yes — if you want a vault strategy and you have read what it deposits into. Skip it if you are happier supplying Aave or staking Curve LP on Convex yourself. A vault is another contract on top of those protocols, not a replacement for understanding them.
Live TVL sits on DeFiLlama. Our rankings table was stamped 2026-08-27. TVL is assets locked — not a safety score and not a reason to deposit.
A vault takes a deposit token and runs a governed strategy — often lending, LP, or a mix. You take Yearn’s code plus every protocol it touches. yVaults are not banks. Harvests and APYs change. Read the strategy, then size as stacked risk.
| Want | Use | Skip Yearn when |
|---|---|---|
| Simple supply | Aave | Always — Aave is enough |
| Curve boost | Convex | You only needed boost |
| Automated strategy | Yearn vault | You cannot name the strategy |
| reUSD CDP | Resupply | You thought Yearn was Resupply |
Convex for Curve boost. Resupply for minting reUSD on Curve or Frax yield collateral. Yearn for vault strategies and, historically, as Resupply’s co-builder with Convex. Three names, three risk engines. Do not deposit in all three because they appear in one sentence.
Strategy bugs, underlying protocol exploits, and APY screenshots that include emissions. YFI is governance, not a dividend coupon. A vault is Yearn’s code plus every protocol it touches. This desk will not call YFI cheap, expensive, or a recommended buy.
The app we name is yearn.fi. Read the vault strategy before you deposit. Resupply remains resupply.fi even though Yearn co-built it. This page is whether a vault is the right wrapper versus picking Aave or Convex yourself as a first step.
Convex, Curve, Resupply, Inverse Finance and Frax share collateral, gauges and stablecoin rails. Read the flywheel first if you are new to the stack.
