Lots your buyers can verify themselves

A catalogue entry is only as strong as the provenance behind it. Attesian lets you attach a signed, verifiable record to the works you handle, so a buyer can confirm a lot themselves instead of taking the description on trust.

Attesian isn't a marketplace — it's the trust layer underneath one. You contribute events and attestations to a work's history and are credited for them, while the record itself stays with the artist.

Buyer confidence, self-served

Anyone viewing a lot can verify the certificate and history in their browser, which lifts confidence in exactly the works that are hardest to sell on trust alone.

Due diligence you don't repeat

Provenance recorded once is verifiable forever, so the work you do to stand a lot up doesn't have to be redone at the next sale.

Lasting credit for what you add

Your contributions to a work's history are attributed to you permanently, even after the work moves on and the artist claims the record.

Questions

Does the record belong to us once we add to it?
No — the record belongs to the artist and moves with them. You keep lasting credit for the events and attestations you contribute, but you can't take the record away.
