Buying and selling

Outcome: you will know what a listing on this market actually is, why a purchase cannot half-happen, what cancelling does and does not do, and what the product will and will not let you do today.

What a listing is

A listing is one signature by the seller. It binds the output carrying the asset to one outcome: any transaction that spends that output must pay the seller the exact listed price. Nothing else about the final transaction is decided by anyone but the buyer.

Three consequences follow, and each is shown in the product rather than buried here:

1. The service never holds anything. Your asset stays on your output; your funds stay in your wallet. There is no deposit, no escrow, and no account.
2. A listing is a public offer. Anyone can settle it at the signed terms. Listing something is publishing it.
3. Cancelling is withdrawal, not revocation. Cancelling removes the listing from this market, but the signature it published stays technically valid until the asset moves or the listing’s expiry block passes. If you need certain revocation, transfer the asset to yourself; that spends the output and no old signature can ever use it again.

The expiry is enforced by the Zcash network itself: the signature commits to an expiry block, and the network refuses the settlement from that block on. It is not a service policy that a copied signature could outlive.

What settles a sale

One transaction. It spends the seller’s asset output and the buyer’s funds, delivers the asset to the buyer’s address, pays the seller the price, and returns the buyer’s change, all together. Either that transaction confirms and all of it happened, or it does not and none of it did. There is no state where the money moved and the asset did not.

The product treats a sale as final only after confirmation depth, the same depth everything else here uses. A transaction in the mempool is shown as pending and can still fail; a chain reorganization honestly reopens a listing whose settlement was disconnected.

The small amount of ZEC riding on the asset’s output (typically 546 zatoshis) transfers to the buyer with the asset. Listings state it, and prices should account for it.

What the figures mean

Floor, volume, and sale counts on the market pages are derived from this service’s open listings and confirmed settlements only, and every market page says so. They are not chain facts and are never presented as such. An empty market shows as empty; nothing is fabricated to look busy.

One market, five destinations

The Market navigation keeps five stable destinations: Overview, Zerdinals, Collections, Tokens, and ZRunes. Zerdinals have the live listing and settlement protocol described on this page. Collections, ZRC-20 tokens, and ZRunes remain archive views until each family has its own reviewed order type. Those pages state that limit and link back to the chain record. They do not copy Zerdinal orders onto assets whose transfer rules are different.

What is live today

Reading the market is always available. Creating a listing is a connected-wallet operation and opens only when a Universe Wallet release qualified for that operation is publicly installable.

A fixed-price Zerdinal purchase has two independent paths. A connected wallet can review and sign its funding input. The pay-from-any-wallet path creates an exact ZEC invoice and, after confirmation, combines those funds with the seller’s already sealed authorization. The service never signs the seller’s asset input. Each path opens only when its own release authorization and dependencies are healthy. Until then the product shows the precise blocker instead of offering a path that cannot finish. See Pay with any wallet and current status.

What is public

Everything. The listing, its price, the seller address, the settlement transaction, the buyer’s receiving address, and the full history of all of it are permanently readable by anyone, on this site and on every other reader of the Zcash chain. Nothing about market activity is shielded or anonymous. If you do not want an address linked to a sale, use a fresh receiving address and understand the linkage a settlement itself creates.
