The full methodology is open source at /methodology/v0.1.

Question 2

Is Yearn Finance considered DeFi or CeFi?

Accepted Answer

Yearn Finance is classified as DeFi on StableLens. DeFi means the protocol runs as a smart contract — users retain custody and execution is on-chain.

Question 3

What is Yearn Finance's audit status?

Accepted Answer

Yearn Finance carries StableLens audit tier "Audited". Audited means at least one independent firm has audited the protocol. See the protocol details panel for the auditor list and links to individual audit reports.

Question 4

What tier does StableLens place Yearn Finance in?

Accepted Answer

Yearn Finance is Tier 1 on StableLens. Tier 1 is reserved for blue-chip DeFi protocols with multi-billion-dollar historical TVL and a multi-year unblemished operational history. Tier 2 is established protocols with strong audit + history. Tier 3 is newer or smaller. Tier 4 is unverified or experimental.

Question 5

Are Yearn Finance yields safe to deposit into?

Accepted Answer

StableLens does not provide investment advice. The risk grade summarizes our analysis but every depositor must do their own diligence. The Deposit links on pool pages route directly to Yearn Finance — StableLens never custodies funds, never signs transactions, and never executes trades on your behalf.
