Claim this listing →Overview
YO Protocol is a multi-chain yield optimizer built on ERC-4626 vaults, currently reporting roughly $12.9M TVL and an 8% yield on its yoUSD product. An agent builder uses it as a deposit target for idle stablecoin balances, routing funds into the vault via standard ERC-4626 deposit/withdraw calls rather than managing individual yield strategies directly.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

State changed on 2026-09-01 (unclear → responding).
This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 40 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. The rate above leaves those checks out; the counts include them.
Last 30 days — to 2026-10-21, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
