Frequently asked questions
0.9.53Short, direct answers about Ordinals, Runes, wallet lookups, prices and privacy on Atrium XBT, each linked to the page that shows how we work it out.
Wallets and lookups
How do I see what a Bitcoin address holds?
Paste the address into the wallet lookup on the settings page. It shows the inscriptions, runes and Bitmap districts the address holds now, its balance, and how much of that balance sits in coins carrying an inscription or a rune.
The answer comes from our own ord index, not an outside API, and no account is needed. Until the index has finished building, the lookup says so instead of guessing.
See looking up your own wallet.
Is it safe to paste my wallet address?
Yes. An address is public, and looking it up gives nobody access to anything and moves nothing.
We never ask for a private key or a seed phrase, and a lookup never asks your wallet to approve anything. Anyone who asks for your seed phrase is not us.
See what you are asked to sign, and where.
Can I see what a wallet bought and sold?
Not yet. The lookup shows what an address holds now, not its history.
A history needs an index of spent transactions, which this dashboard doesn't run yet.
See what the dashboard does not have.
Prices and values
How does Atrium XBT value an Ordinals collection?
A collection's value is the median price of its clean sales our own node saw in the last 90 days. Wash-flagged sales and outliers are left out, and the value is shown only when there are at least 3 such sales.
See collections: membership, holders and sales.
Why is a collection's value different from a marketplace floor price?
A floor is the lowest asking price at one marketplace; our value is what items actually sold for. The two drift apart when listings move faster than sales.
A value from sales is not an asking price and not an appraisal. Since 12 October 2026 no value here comes from an outside marketplace.
See how a collection is valued.
Why does a collection show a dash instead of a value?
Our node saw fewer than 3 clean sales of it in the last 90 days, so no collection value is shown. In a wallet, its items are still valued from older sales, their own last sale or the sats they sit on, each labelled with its source and how sure it is.
See collections: membership, holders and sales.
Where does the BTC/USD price come from?
It is estimated from our own node's blocks. People pay round dollar amounts, so a day's payments cluster at the sats amounts that equal $10, $20, $100 and so on, and where those clusters sit gives the price.
It is a day's average of what people paid, not an exchange quote, so it lags fast moves. An estimate the method isn't sure of is marked as low confidence.
See every section, and its source.
Runes
How is a rune sale found and priced?
A rune sale is a confirmed transaction that carries a Runestone, moves runes from one wallet to another and pays the seller in bitcoin. Its price is the bitcoin the seller received.
The price per token is that price divided by the units the buyer received, read from the Runestone's edicts. Every sale carries its transaction id, so you can check it on any block explorer.
See how a rune sale is found and priced.
Why is a rune's price here different from a price aggregator's?
Every rune price here is made only of trades in confirmed Bitcoin transactions. An aggregator blends every venue it tracks, including other chains a bridged token trades on, so the two answer different questions.
See a token that also trades on another chain.
What are the rune market Greeks?
They borrow option-market letters for their plain meaning: delta is price change, gamma the change in that change, theta steady drift, vega volatility, beta co-movement with the rune market, and alpha return beyond what beta explains.
Runes have no options market, so these are not option Greeks. Each rune carries a confidence label (good, fair or low) because thin markets give noisy numbers.
See rune prices and the rune market Greeks.
Collections and inscriptions
How do you decide which inscriptions belong to a collection?
The list of collections comes from the Wizards of Ord collection registry, a public-domain (CC0) list, and each member is checked against our own ord index. Collections our node finds by watching a parent inscription mint its children are added too.
An item is marked verified only when our ord index shows it belongs, for example as a child of the collection's parent inscription.
See collections: membership, holders and sales.
How is an inscription sale detected?
An inscription sale is a confirmed transaction with a signed marketplace listing in it. The price is the payment output paired with that listing.
Which inscription moved is worked out from its reveal transaction, from earlier sales of the same item, or from our ord index. A sale none of these can place is kept and marked "unknown" rather than guessed.
See how an inscription sale is found and priced.
What counts as a wash trade?
A sale is flagged when the same person is probably on both sides of it. Four rules catch the plain cases: the same address on both sides, an item going there and back, the same two wallets trading 3 or more times in both directions, and a seller paying for their own sale.
Flagged sales stay visible with the rule that flagged them, but never count towards volume, prices, rankings or indexes. A flag describes a pattern of transactions, not an accusation.
See wash-trade flags.
What are the Ordinals and Runes market indexes?
One number each for the Ordinals and Runes markets, both starting at 100. Each is the equal-weighted geometric average of ten members' prices against where they started, so 112 means the basket is 12% above its start.
The members are the ten collections and the ten runes our own node saw trade most by value over 30 days, with wash trades left out.
See the Ordinals and Runes market indexes.
BRC-20, rare sats and bitmaps
Does Atrium XBT show BRC-20 balances?
Yes, in the wallet lookup: each ticker's balance, how much of it is available and how much is transferable, read from our own BRC-20 indexer (OPI), which runs beside our node. When that indexer isn't connected, can't be read or is still catching up, the lookup says "BRC-20 balances unavailable" rather than showing none.
The balances are listed, not valued: they aren't counted in the wallet value.
See what the dashboard does not have.
Does the wallet lookup show rare sats?
Yes: the lookup rates each coin's sats by Ordinal Theory's rarity, from uncommon to mythic, and lists pizza, vintage, block 9, block 78 and palindrome sats, using the sat ranges in our own ord index. If that index can't give a coin's sat ranges, the lookup says so rather than showing none.
Separately, a Labs experiment labels sat numbers by their mathematical class (prime, square, Fibonacci and so on). Those are our own labels, not ord's rarity.
See math-labelled sats.
How are Bitmap districts found and valued?
A district is a text inscription whose content reads "N.bitmap", and only the first inscription of each number is the valid claim, as recorded by the OPI bitmap index our node runs. Districts are valued from sales of valid claims only; while that index is unavailable or behind, no district is valued as a bitmap.
The wallet lookup lists the Bitmap districts an address holds.
See how values come from recent sales.
Fees and blocks
When is it cheapest to send a Bitcoin transaction?
There is no fixed cheap hour. The "Cheapest times to send" card on the dashboard shows, for each hour of the week, the median fee rate that reliably got into blocks over the last four weeks.
Four weeks gives about four samples per slot, so one fee spike can move a slot. A cheap hour in the past is a habit of the market, not a promise.
Which mining pools leave inscriptions out of their blocks?
The dashboard measures it per pool over 30 days. When each block arrives, our node compares its mempool with what the pool mined and counts how many well-paying inscriptions, runes, BRC-20 and Alkanes transactions it left out, against ordinary ones.
Pools are named from the coinbase tag, which a pool can set to anything.
See which mining pools leave inscriptions out.
Data and privacy
Do you keep the addresses I look up?
Not as a record of who looked. A lookup's result is kept briefly as a cache against the address, which is public anyway, and is never tied to who asked.
The list of addresses you looked up stays in your browser tab and is forgotten when you close it, unless you sign in to an account.
See privacy.
Do you use cookies or third-party tracking?
No third-party tracking, advertising or analytics scripts. Visits are counted as de-identified daily totals with no cookie; a sign-in cookie is set only if you sign in to an account.
Browsers that send Global Privacy Control or Do Not Track are not counted, and you can switch counting off on the about page. Totals are deleted after 13 months.
See privacy.
Can I quote or cite your data?
Yes. Quote any figure, chart or finding, including in AI-generated answers, and credit "Atrium XBT" with a link to the page and the date you read it.
Please don't copy the data in bulk, mirror the site, resell it or scrape the internal /api/ endpoints. Figures from other services stay under their own terms.
See using our data.
The site
Is Atrium XBT free?
Yes. The dashboard and these pages are free to read and need no account.
Paid plans are not available yet, and nothing can be bought on the site today.
See about Atrium XBT.
Can I buy or sell inscriptions on Atrium XBT?
Not yet. The marketplace is not open, so today the site shows sales that happened elsewhere, read from the chain.
It is being built to be non-custodial: your own wallet would sign each trade, and the site would never hold your keys or coins.
See what you are asked to sign, and where.
Is anything on Atrium XBT financial advice?
No. It is a data tool, and nothing here is a recommendation to buy, sell or hold anything.
Labels such as "whale" or "smart money" describe past on-chain behaviour, not predictions.
See the terms.
Also as plain Markdown. See every methodology page.
