StampDEX documentation

The trading venue for Bitcoin Stamps and SRC-20. This site documents how a trade is built, where your funds sit at every stage, and what the venue can and cannot do.

StampDEX is the marketplace and explorer at stampdex.fun for two Bitcoin protocols: Bitcoin Stamps, artwork written into Bitcoin transactions, and SRC-20, the token standard built on the same mechanism. You can browse the whole venue without a wallet. Connect one only when you want to trade.

This documentation exists for one reason above the others: a trade on Bitcoin takes time, and during that time your money is somewhere specific. Every page here says where.

The StampDEX market page in the dark theme: an SRC-20 token table with per-token source labels, floor prices, volume, and holders. Missing values show as dashes, not zeros.
The venue itself. Every row carries the deployment transaction that identifies the token, and a source label for each figure. Captured from production, 2026-08-28.

  • Traders

    You want to know what a listing really is, what it costs, and what happens between signing and settlement. Start with Buy SRC-20 and Where your funds are.

  • Collectors

    You want to identify a stamp beyond its picture and buy it without guessing. Start with Collect Bitcoin Stamps and Asset identity.

  • Application developers

    You want the same data the site reads, with no key and no account. Start with the API quick start.

Trades are executed at StampDEX, not inside other Bitcoin Universe products. The registry that describes the Universe ecosystem records both Stamps and SRC-20 as mode: external-execution, owned by StampDEX. Other Universe surfaces can show you a stamp or a token, but the order book, the matching, and the settlement happen here.

While an SRC-20 trade settles, your BTC is not in your wallet and not in the seller’s wallet. It is in escrow addresses created for that one listing, which StampDEX controls. StampDEX states that before you sign. Everything on this site uses the same four colours to say where value sits:

  • Buyer side: held by the buyer, or delivered to the buyer
  • Seller side: held by the seller, or delivered to the seller
  • Held by StampDEX for the length of one trade
  • Settled on Bitcoin, final

Nothing on this site is financial advice. StampDEX shows identity and market facts and builds transactions. What you buy, and at what price, is your decision.
