HOW IT WORKS

Create your first certificate in three simple steps

01

Set up your artist profile

Add the details collectors need to recognise you: your bio, image, links, and signature.

02

Document the artwork

Add photos, title, medium, dimensions, year, and edition details to create a complete record.

03

Share the certificate

Send it as a link, print it, or connect it to a proofmark.art tag attached to the artwork.

CERTIFICATE PAGE

A certificate page for every work

Each work gets a public verification page that can be shared with collectors, galleries, marketplaces, or archives.

FAQ

Certifying your artwork, explained

Why do I need to certify my artwork?

A certificate gives each work a clear record of authorship, artwork details, provenance, and verification. It makes the piece easier to share, sell, insure, and trust after it leaves your studio.

Do I need to buy a proofmark.art tag?

No. You can create certificates, share certificate links, print certificates, and manage your portfolio without buying a tag. The tag is an optional physical NFC sticker.
