Mars Market — reader-friendly access guide

Step six — placing a first order

The sixth step is placing a first order. With a funded wallet and a working login, the storefront is ready to use. The order flow is conventional in shape — pick a listing, add it to a basket, check out — and a little different in the way the funds move.

Choosing a vendor and a listing

Open a category from the storefront menu. Each listing shows a price, a description, a shipping section and a vendor badge. Click the vendor badge to read the vendor page. The vendor page carries their published PGP key, their finalisation behaviour and their dispute record. On a first order, the safer choice is a vendor with a long history and a low dispute rate, even if the price is a little higher than a newer competitor.

Reading a listing carefully

The listing carries the price in the coin the vendor prefers, the shipping options, the regions the vendor will ship to and any conditions the vendor sets — minimum order size, packaging notes, finalisation rules. Read all of it before checkout. Most first-order disappointments come from missing a line on the listing rather than from the storefront itself.

How the multisig escrow opens

At checkout the storefront opens a two-of-three multisig contract for the order. Three keys exist — yours, the vendor's and the platform's — and any two of them can release the funds. Your wallet balance is moved into the contract, the vendor sees that funding has happened and ships the order. While the contract is open, the platform alone cannot move the funds; that property is the structural reason the escrow is meaningful rather than ornamental.

Receiving and finalising

When the goods arrive, sign the release inside the order panel. Your signature plus the vendor's signature on the same contract releases the funds to the vendor. If the goods do not arrive, or if they arrive wrong, do not sign the release — open a dispute from the same panel and the arbitration team reads the order log and the messages. The platform key swings the dispute on the basis of what the arbitration finds. A first-time buyer rarely needs to open a dispute, but knowing the path is there is half the reason the escrow design is worth the effort.
