Applying as a vendor: what the three markets look for

If you are reading this you have likely sold elsewhere and are deciding where to go next. All three markets gate applications, all three review new sellers before listings go live, and all three publish a vendor agreement worth reading once before you apply. None of them is a place you can post a storefront on a whim, which is exactly the property that keeps their listings worth browsing.

The form

The platforms ask for the same broad set: a handle, the areas you intend to list in, a sample listing written to the platform's schema, and proof of standing from a prior platform if you have one. Anubis adds a short questionnaire on shipping cadence and dispute history. Nexus adds an agreement attestation you sign as part of the application. Osiris asks how you intend to handle direct settlement, since its walletless flow puts the buyer-to-vendor leg at the centre of how you operate rather than at the edge.

What review screens for

Three things. Whether the listings you mean to publish fit the rules. Whether the areas you are entering have moderation capacity, since some are throttled to keep the dispute queue sane. And whether your stated history actually maps to a clean record. The review is not a formality; all three reject applications that do not hold up, and a thin or inconsistent history is the most common reason.

A realistic timeline

From application to first listing is roughly a working week when the application is clean. The bottleneck is moderation review, not the technical setup, which finishes in minutes. If you sit in review longer than that, ask politely on the vendor channel for a status; the teams are responsive but do not auto-bump a queue.

How settlement shapes the work

This is the part sellers underrate. On Anubis and Nexus you onboard into two-of-three multisig escrow by default, which means you hold a signing key and counter-sign releases. On Osiris you onboard into walletless direct settlement, where buyer funds never pool centrally and the buyer-to-vendor leg is the contract. Neither is harder once you are set up, but they shape your dispute posture differently, so read the escrow guide before you choose. Build a clean vendor reputation early; the feedback record follows you across onion mirror rotations and is the asset that compounds.

Frequently asked

Do I need a vendor bond?

Requirements vary by platform and are set out in each vendor agreement. Read the agreement before applying so there are no surprises at onboarding.

Can I list on more than one of the three?

Yes, and many established sellers do. Each application is reviewed independently, and your reputation on each marketplace is separate.

How do I keep current after onboarding?

All three keep a vendor channel where the team posts updates, and joining it is the easiest way to stay current on onion mirror rotation and policy changes.
