Where every number on VYLØS comes from: each data provider, how often it refreshes, how figures are calculated, and what happens when a source fails.
VYLØS does not create market data. It reads it from the providers below, stores little of it, and shows it next to where it came from. This page lists each source, how fresh it is, and how the derived figures are worked out.
Market cap is the price multiplied by the circulating supply. Fully diluted valuation is the price multiplied by the total possible supply. Both use the figures CoinGecko publishes for each coin.
Price changes are measured in US dollars over the window shown. When a page is set to another currency, VYLØS converts the USD value at the latest reference exchange rate, so a change in that currency can differ slightly from the USD change shown.
Converter pages such as BTC to EUR multiply CoinGecko's average USD price by the reference exchange rate. That is a market average, not a quote: an exchange will charge its own spread and fees.
The US debt clock separates two numbers. The reported figure is Total Public Debt Outstanding from the Treasury's latest record. The moving figure is a labeled estimate that runs from that record at the recent average pace, and it resets each time the Treasury publishes.
On the FOMC page, rates, ranges and votes come from each Federal Reserve statement. The Bitcoin columns use Coinbase BTC-USD hourly candles, measured from the 2:00 PM Eastern release to the same time 24 hours and 7 days later.
The bubble chart and the heatmap leave out stablecoins, because a coin pinned to a dollar has no move to show. Heatmap tile area uses the square root of market cap so smaller coins stay readable beside Bitcoin.
A number VYLØS cannot back is left blank or marked as delayed, never estimated to fill the gap. Pages keep working on whatever data is still available, and they say so when a section could not load.
Upstream providers sometimes disagree or publish errors. VYLØS passes their figures through as published, apart from known bad prints it screens out of derived charts, so a wrong figure at the source can reach this site until the source corrects it.
If a figure looks wrong, write to team@vylos.io with the page and the number. Corrections to anything VYLØS wrote by hand, such as the FOMC table, are made directly on the page.
Nothing on VYLØS is financial advice. Data can be delayed or wrong, so check anything you plan to act on against the original source.
