# How our data works

Updated 13 November 2026

Sales Tracker is a data provider for Telegram gifts. Every figure on it comes from listings and completed sales we read ourselves, from the marketplaces and from Telegram's public pages. Nothing is estimated where a real price exists, and where data is missing the page says so. This page explains the sources and the methods in plain terms.

## Sources

- **Marketplaces**: listings and completed sales on Portals, MRKT, Tonnel, Getgems, Fragment, Market App and Telegram's own market, read from what each one shows publicly, around the clock.
- **TON blockchain**: sales that settle on chain (Getgems, Fragment) and the TON wallets that hold collectible usernames and +888 numbers.
- **Telegram's public gift pages** (t.me/nft/...): each upgraded gift's model, backdrop, symbol, number and owner where shown. This index of about 12 million gifts powers the Finder and portfolios.
- **Fragment**: collectible usernames and anonymous +888 numbers, read every few minutes.
- **GRAM (TON) price**: Binance first, then CoinGecko and tonapi.io, for prices in dollars and other currencies.

## Sales

A sale is recorded once, at the price paid, with its marketplace and time. The same sale seen twice (for example on a marketplace and on chain) is counted once. Where a marketplace adds a buyer fee to the price, the recorded price includes it. Dollar figures for past sales use the TON price at the hour of each sale, not today's.

## The floor

The floor of a collection, a model or a backdrop is the cheapest listing of it right now across every marketplace we read, and the page names the marketplace that holds it. A listing its marketplace stops showing, or one that has sold, drops out. When nothing is listed, the last sale stands in, and the page says so.

## Changes, market cap and charts

- **24 hour change**: the average sale price of the last 24 hours against the 24 hours before. Too few sales in either window shows no change rather than a misleading one.
- **Market cap**: a collection's floor (or last sale) times the number of gifts issued.
- **Charts**: medians or damped averages per period, so one odd sale does not bend the line.
- **Username floors**: the cheapest quarter of real sales of 100 TON or more in 30 days, not the cheapest fresh listing.

## Values and estimates

A gift's estimated value starts from recent sales of its model and adjusts for its backdrop, a monochrome match and its number, measured from past sales of similar gifts. Each value in a portfolio shows where it came from: recent model sales, the cheapest listing or older sales. A deal is a listing under what comparable gifts sold for, and names the price it was compared with.

## How often it updates

New sales appear within seconds to a few minutes of happening. Listings and floors are read continuously; gift counts and rarity refresh every few minutes; usernames and numbers every few minutes from Fragment. Pages for search engines and AI answer engines are redrawn every few minutes and carry the date of their figures.

## Errors and corrections

If a price or a sale looks wrong, tell us which gift, model or sale it is and we will check it.
