A Yearn V3 vault takes deposits of one token and issues shares for them. It keeps some of that token idle for withdrawals and lends the rest to strategies, each of which puts the token to work somewhere and reports what it owes back. What a share is worth is the vault’s answer: total assets divided by shares, which is what the Share price column on the roster shows, in the vault’s asset.
The roster is every vault the five V3 factories deployed — 250 of them at block 26,217,692 — which is a wider list than the shortlist Yearn endorses. Anyone may deploy from a factory, and a deployment is announced by a creation event on that factory, which is the only enumeration there is: a vault keeps no list of its siblings and a factory keeps no list of its children. Each vault the sweep found is then asked which factory made it, which release it runs and which token it takes, and the three answers must match the event before it joins the roster.
That makes the roster a floor. The V3 vault is a contract, so it can be compiled and deployed by hand with no factory involved, and such a vault announces nothing and appears on no list anywhere; a vault deployed since the census block joins when the census runs again. Two lists that look like the roster are neither: the registry answers the endorsed shortlist mixed with tokenized strategies no factory made, and the pointer it keeps to the release registry has fallen behind at three of the five factories.
Endorsement is Yearn putting its name to a vault, and the roster shows it as a badge and the Yearn mark. It is an act Yearn can undo, so the badge describes the block the roster names and nothing later. A vault without one still carries the words “Yearn V3”, because that is what it is: a contract from a Yearn factory, running Yearn’s vault code at the release the row states. An endorsement is Yearn’s word on the vault; the strategies behind it are judged one at a time.
Every figure on the roster is a quantity of one vault’s asset, and the roster holds 72 different assets. Vaults are grouped by asset and ordered inside a group by size, so the only comparisons the page offers are between quantities of the same token. There is no dollar value anywhere and no total across the page.
Yearn V2 is a separate registry with different vault code and is absent from this page. One address’s holding in a vault, and the history behind it, opens from the vault’s page: enter the address under “Find an address in this vault”. There is no census of Yearn holders, so no count of them is stated.
