Membership comes from the census and only from the census: every address named either side of any Transfer a vault has ever emitted, swept whole rather than from a floor, and proven complete by Σ balanceOf equalling totalSupply() wei-exact at the census block the listing states. A sweep that came back short cannot pass that check, so a silent partial answer becomes a refused load and the previous census stands. Transfers, first seen, last activity and what the holding address is all come from that sweep, at that block. The one priced figure on a card, Value · USD, is the census’s too and is explained below; there is no rate and no yield anywhere in this section.
The listing rests on value. Each card’s Value · USD is the census’s figure at the census block: the balance at that block through the vault’s own convertToAssets and Aave V3’s oracle on Ethereum (IAaveOracle.getAssetPrice) at the same block, the oracle and the block named on the figure’s receipt — computed once by the daily census and never read for a listing page, so it is what a position was worth at that block and says nothing about now. Where a vault’s asset is itself a wrapper the oracle does not price directly (a stake token holds a static aToken), the census prices that wrapper’s underlying and converts through the wrapper’s own convertToAssets, and the receipt states the hop. The Size filter’s brackets are whole-dollar lower bounds on that value, and its Unpriced option is exactly the rows the oracle declined. Sorting by share of the vault orders each row’s balance over its own vault’s supply at the census block, which compares across vaults; sorting by shares sorts on the raw balance in each vault’s own units — the share tokens here have 6, 8 and 18 decimals — so it orders raw share counts and not amounts of anything comparable.
The section lists two layers of one machine, and a reader must not add them together. An Umbrella stake token’s own shares are a claim on a single position — the static aToken it is staked on — so that stake token’s holding of the wrapper and the stake token’s own holders are the same assets at two heights rather than two sets of assets. Nothing here sums them: the census line counts positions and Value · USD is per row, so no total is rendered anywhere in this section. Each static aToken’s page names the stake token that holds it and the share it holds, and each stake token’s page names the wrapper its own assets sit in.
5 catalogued vaults have never been held: no address has ever held shares of waEthWBTC, waEthUSDG, waEthEURC, waEthDAI or waEthUSDS as of block 26,235,125. The sweep ran and returned no logs at all — a reading about those vaults, not an absence of data about them.
The search matches an address, or a fragment of one, against the holder. An address the census has never seen has no row here — the listing answers no rows for it and records nothing about the search, because a set assembled from what visitors typed would be a public record of who looked at what.
