import ProductShot from '../../../../components/screens/ProductShot.astro';

**For:** anyone, with or without a wallet.
**Goal:** find a token and understand its numbers before you open its page.
**Prerequisites:** none.
**Chain and network:** Bitcoin mainnet. **Safety:** reading only, nothing is signed.

## Where it is

[stampdex.fun](https://stampdex.fun) opens the board. `/src20` and `/markets` are the
same view.
<ProductShot

  alt="The StampDEX market board in the light theme: a table of SRC-20 tokens with columns for ticker, deployment transaction, floor, volume, holders, and mint progress. Several rows show a double dash where no source answered, rather than a zero."
  caption="The market board. The deployment transaction sits in its own column beside the ticker, and rows with no reading show a dash."

## The columns

| Column | What it is | When it is unknown |
| --- | --- | --- |
| Ticker | The short name | Never |
| Deployment transaction | The transaction that created the token, in its own column beside the ticker | When no source reported a deployment. The ticker is never used in its place |
| Floor | The lowest live listing price, in sats per token | When no source priced it. Not shown as 0 |
| Volume | Traded value over the stated window | When no source answered |
| Holders | Addresses holding a balance | When no source answered. A genuine 0 is shown as 0 |
| Mint progress | Minted supply against max supply | When supply figures are missing |
| Market cap | Price times supply, from the stated source | When no price exists, or when the computed cap exceeds the total supply of Bitcoin |

That last rule is not hypothetical. A token declaring an absurd max supply once
produced a market cap above 200 million BTC. StampDEX reports a cap larger than
21,000,000 BTC as unknown rather than repeating it.

## Every number names its source

Each row carries a `sources` map with one entry per figure. The values are:

| Value | Meaning |
| --- | --- |
| `stampchain` | The number came from the stamp index |
| `stampdex` | The number came from trades and listings made on StampDEX itself |
| `none` | No source had an answer. The field is unknown |

The source map decides what you see, not the number that happened to arrive. A nested
block can carry a literal zero while the source map says `none`; the source map wins,
and the field renders as unknown. See
[Unknown is not zero](/docs-stampdex/zh-cn/concepts/unknown-is-not-zero/).

## Totals name their coverage

The board's volume total sums only the tokens a source could answer for, and the chip
says how many that is. `0.037 BTC (3/106)` means three of the one hundred and six
tokens on the board had a volume reading. It is not the volume of the whole board.

Underneath the counts, the page says the same thing in words: how many tokens have a
listing you can fill on StampDEX, and how many carry a price read from the index with
no order behind it.

## Sorting and filtering

A token nobody has priced does not sort as though its price were zero, and a price
range filter does not return it as a match. An unknown is excluded from a comparison
rather than treated as the bottom of it.

## How to verify

```bash
curl "https://stamp.api.bitcoinuniverse.io/api/v1/market/tokens?limit=2"
```

The `sources` object on each row is the same one the board reads.

## Common failure states

| You see | Cause | What to do |
| --- | --- | --- |
| Most rows unknown | The index did not answer | Check [the status endpoint](/docs-stampdex/zh-cn/api/status/) |
| Numbers look old | Server-side caches, 20 to 300 seconds depending on the surface | Wait. Polling faster returns the same answer |
| HTTP 429 from the API | Over 300 requests per minute | Slow down. See [Rate limits](/docs-stampdex/zh-cn/api/rate-limits/) |
