Glossary

Anchor UTXO. The small marker output a seller’s listing spends and returns. 548 sats. StampDEX builds one when your wallet has none.

Bitcoin Stamps. Artwork stored directly in Bitcoin transactions. The image bytes live on the chain itself, so the artwork exists as long as Bitcoin does.

Confirmation. A transaction included in a block. Each further block is another confirmation. StampDEX settles an SRC-20 order at two.

CPID. The Counterparty asset id of a stamp. Stamps are issued as Counterparty assets, and this id is part of a stamp’s identity.

Deployment. The transaction that created an SRC-20 token: its rules, max supply, and mint limit. The deployment transaction hash identifies the token.

Dispenser. A Counterparty vending contract. Send it the asking BTC and it dispenses the asset. Closing one has a protocol cooldown before the asset returns.

Dust output. A small output that carries structure rather than value. SRC-20 data chunks are 330 sats each; the seller anchor is 548.

Escrow addresses. Addresses created for one listing that hold the tokens and the buyer’s payment during an SRC-20 trade. StampDEX controls their keys, server side and encrypted, for the length of that trade.

Execution mode. How a trade is executed. external-execution means the trade runs at StampDEX rather than inside another Bitcoin Universe product.

Fee rate. What a transaction pays the Bitcoin network per virtual byte, in sat/vB. It goes to miners, not to StampDEX.

Floor. The lowest live listing price. When no listing exists there is no floor, and StampDEX says so instead of showing 0.

Index. The service that reads the Bitcoin chain and answers questions like who holds what. See Data provenance.

Mint progress. How much of a token’s max supply has been minted, as a percentage. At 100 percent, minting is over.

One-time action challenge. A short message your wallet signs before a mutation. It names the action, your address, and a hash of the exact request, expires in five minutes, and works exactly once.

PSBT. A partially signed Bitcoin transaction. StampDEX builds it; your wallet reviews and signs it. Nothing moves without your signature.

Reorg. A chain reorganisation, in which a block that was part of the chain is replaced. StampDEX re-checks trades settled in the last 24 hours against it.

Sat, sats. The smallest Bitcoin unit. 100,000,000 sats equal 1 BTC. Listing prices here are quoted in sats per token.

Service fee. StampDEX’s own fee: 1.5% per side of an SRC-20 trade with a 500 sat minimum per side, or a flat 1,500 sats on a mint, deploy, or transfer. See Fees.

SIGHASH_ALL | ANYONECANPAY. The signature type a seller uses on their listing input. It commits to that one input and to all the outputs, which is why a listing can sit on the book without locking the rest of the seller’s wallet.

Source map. The object beside every market row naming where each figure came from: stampchain, stampdex, or none.

SRC-20. A token standard built on Bitcoin Stamps. Deploys, mints, and transfers are stamp transactions the index reads.

SRC-101. A name standard in the same family, used for on-chain domain names.

Ticker. The short name of an SRC-20 token, such as KEVIN. A ticker is not an identity. See Asset identity.

Unavailable. We could not ask the source. Different from unknown.

Unknown. The source had no answer. Never rendered as 0.

UTXO. An unspent output, the unit of Bitcoin ownership a transaction spends.
