代币部署与唯一性核验

A deployment is the transaction that created an SRC-20 token: its rules, its max supply, and its mint limit. That transaction hash is the token’s identity. The ticker is a label.

The address form

https://stampdex.fun/trade/src20/KEVIN/23765f9bc6b87e078b1f93ed213f90b9004998336575f726e46f34ddbea5e5f3

Ticker plus deployment transaction. This is the link Copy link gives you, the link the tab title and the shared card describe, and the link a market row opens.

Two shorter forms resolve to it:

Form	What StampDEX does
/trade/src20/KEVIN	Resolves the ticker before showing a market
/trade/src20/by-tx/<deploy transaction>	Looks up the transaction and replaces the URL with the full form

The four answers to “which deployment”

The deployments endpoint reports its answer in a resolution field, and the site’s gate follows it:

resolution	Meaning	What you get
single	Exactly one deployment claims the ticker	The market, at the full URL
ambiguous	More than one does	Each deployment with its transaction, block, and creator. No market until you pick
unknown	The index answered, and holds no deployment for the ticker	Nothing to price, nothing to trade
unavailable	The index did not answer	A retry. No market

unknown and unavailable are different answers and are never rendered as each other. One means nobody deployed this ticker. The other means StampDEX could not ask.

Reading it yourself

curl "https://stamp.api.bitcoinuniverse.io/api/v1/market/deployments/KEVIN"

The response carries resolution, source, source_available, observed_at, and a deployments array. Each entry names tick, deploy_tx, deploy_block, deploy_time, creator, max_supply, and mint_limit.

Going the other way, from a transaction to a token:

curl "https://stamp.api.bitcoinuniverse.io/api/v1/market/deployments/tx/23765f9bc6b87e078b1f93ed213f90b9004998336575f726e46f34ddbea5e5f3"

That returns found and the deployment. A value that is not 64 hex characters is rejected rather than searched for.

Why the gate exists

You cannot buy, sell, or sign anything from a ticker StampDEX has not resolved to exactly one deployment. A market shown under an ambiguous ticker would be a market in something unspecified.
