Selling on Mars Market
Vending on Mars is a smaller, more screened process than on the volume markets. New accounts pass a deposit and a public PGP check before any listing goes live, and the operator caps the vendor count rather than chasing it. That screening is why the roster stays trustworthy, and it is also why getting in takes a step more than signing up on a bigger, looser market.
Getting approved
Open a vendor account, post a public PGP key, and put up the required deposit. The deposit is held against disputes and refunded as your record stays clean. The PGP key is how buyers encrypt shipping details to you, so it has to be a key you control and can keep. Approval is manual, which is the point. A screened roster is what keeps the lookalike problem manageable for everyone on it.
Listing and feedback
Listings carry a short signed seller intro, a description block, and a feedback strip ordered by most recent. That ordering surfaces problems faster than a star average, so a vendor who responds to negative feedback quickly and specifically ages better than one who ignores it. The region filter keeps your listings in front of buyers you can actually ship to.
Staying in good standing
Your trust badge reflects your unsigned feedback window, your signed dispute outcomes, and your time on the platform. It refreshes nightly, so it tracks the last quarter of activity rather than one dramatic order. Keep the dispute rate low, answer messages, and ship inside the window you state, and the badge holds. Let any of those slip and it shows, which is the incentive structure doing its job.
