Collections: membership, holders and sales
0.9.53Which inscriptions belong to a collection comes from a public registry checked against our own ord index; holders and sales come from the chain.
In one sentence
A collection's members come from the Wizards of Ord registry, plus collections our own node finds, checked against our own ord index; its holders are read from that index, and its sales and value from the confirmed sales our node found, with wash-flagged sales left out.
As of 2026-10-21, 999 collections from the Wizards of Ord registry had a page here.
Membership
- The list of collections, and how to recognise each one's members, comes from the Wizards of Ord collection registry, a community-curated, public-domain (CC0) list. We keep a copy of it and refresh it once a day from the registry's public lists: every row is checked, and a download that would shrink the list by more than half is refused, so a bad download keeps the last good copy.
- Collections our own node finds are added too: a parent inscription that keeps minting children, or the parent of something people hold, once it has enough children and a name that doesn't copy anyone's.
- Members are then resolved from our own
ordindex. A collection counts as fully known once that has finished. - An item is marked verified only when our
ordindex shows it belongs: it is a child of the collection's parent inscription, or it is in a gallery the registry (or we, by hand) point to. A gallery nobody vouches for, or a marketplace's old list, never counts as verified. - Until then, and for collections the registry doesn't cover, membership can come from an archive of a defunct marketplace's lists. Those lists are used only where they agree with the chain; lists the curators found materially wrong are not used.
- Collections the registry's curators have held back are shown without members.
Holders
Read from our own ord index: who holds each member right now. The page shows how many wallets hold it and how concentrated it is. Holders are kept for collections someone holds or watches and for the most-traded ones.
Sales
Inscription sales found by our node (see inscription sales) whose inscription is a member. Wash-flagged sales are listed but left out of counts and medians (see wash-trade flags).
Value from recent sales
A collection's value is the median price of its clean sales our own node saw in the last 90 days: wash-flagged sales are left out, and so is a sale priced far from the sales around it in time (the same outlier test rune prices use). It is shown only when there are at least 3 such sales; with fewer the value is a dash, and a wallet's total leaves those items out rather than counting them at nothing. The sales come from three places, each counted once: sales our node found in blocks, the older ones it archived, and an item's last sale found by walking its history back on chain.
The 7-day change compares the median of the last 7 days with the median of the 30 days before them, and needs 3 sales on each side. Bitmap districts are valued the same way, from sales of a district's first (valid) claim only.
A value from sales is not an asking price and not an appraisal. Since 12 October 2026 no figure here comes from an outside marketplace.
