Portable evidence
A portable order is more than a listing card. It combines the proposed transaction with a signed publisher identity, order terms, asset claims, referenced inputs, and a stable identity. That evidence can be shared through Nostr and interpreted by compatible Ordex experiences.
Portability does not make every market identical. Each experience may choose which orders to display and which evidence source to trust.
Protocol families
Orders are grouped into families first, then into the individual protocol inside each family. Choosing a family shows every order it contains; choosing one protocol narrows the view to that market alone. A market experience reads the family list from Ordex itself, so the grouping stays the same wherever you browse.
| Family | Protocols inside it | What a check proves |
|---|---|---|
| Bitcoin | Bitcoin PSBT | The exact output is unspent. |
| Ordinals | Ordinals, Bitmap, BRC-20, TAP, DMT, UNAT, Names | Where the inscription sits right now. |
| OP_RETURN | OP Inscriptions, OP-20, OP Names | Where the inscription sits right now. |
| OP_DROP | Taproot OP_DROP | Where the anchor inscription sits right now. |
| Atomicals | ARC-20 | The exact output is unspent. |
| Runes | Runes | The exact output is unspent. |
| Tokens | Alkanes, Mezcal, DUST20 | The output or inscription location only. |
Every family listed here settles as a Bitcoin PSBT you review and approve in your own wallet. For an output-based market, Ordex proves the output is unspent and builds the order around it; it does not read the token balances that output carries, so check those in your wallet before you sign. For an inscription-based market, Ordex reads the current location of the inscription from its own index; token balances and transfer state are a separate question it does not answer.
Ordex has no artifact builder, verifier, or source adapter for Dogecoin or Counterparty assets, so those markets are not listed. Nothing in Ordex will present a Bitcoin transaction under a protocol label it did not verify.
A lifecycle you can read
| Signal | What it means for you |
|---|---|
| For sale | The output this listing sells is unspent and the asset is where the seller said it is. This is a moment in time, not a reservation. |
| Checking | Ordex has not been able to reach its Bitcoin node or its index for this listing yet. Wait and refresh before acting. |
| Being spent | An unconfirmed transaction is already spending the output this listing sells. It may still be replaced or dropped, so nothing is settled. |
| No longer available | The output was spent in a block. The listing cannot be bought. |
| Sold | The transaction Ordex checked for this listing spent the output. |
| Not usable | The artifact or its safety profile did not pass review. Do not bypass the warning. |
| Removed | The seller took the listing out of this market. That is not an on-chain cancellation. |
Every listing also carries the time of its last check. Ordex rechecks live listings on its own schedule and again immediately before it hands an order to your wallet, and it closes that handoff while a check is too old to mean anything.
Verification is layered
Transaction structure
The PSBT is parsed consistently so its identity and referenced inputs can be understood.
Input availability
The referenced outputs are checked against current Bitcoin information at a specific moment.
Claimed location
When an ordinal asset is claimed, its known location is compared with the order input.
These signals help you make a better-informed decision. They cannot reserve an input, prevent a competing transaction, or guarantee what the next block will contain.
Signatures preserve provenance
Portable evidence can be approved through a NIP-07 signer and shared as a signed Nostr event. The signature links the published evidence to a Nostr identity; it does not prove that the publisher is trustworthy or that a future settlement will succeed. Review the evidence and the identity together.
Your control stays with you
Ordex is not a wallet.
It does not ask for your seed phrase, hold funds, sign a Bitcoin transaction, choose a fee, or broadcast on your behalf. Nostr approval stays inside your signer, and Bitcoin approval stays inside your wallet.
Before settlement, refresh the order and inspect every transaction detail in a wallet you trust. Bitcoin transactions are difficult to reverse once confirmed.
