From Artwork to Certified Proof in Minutes

Four simple steps to create an unbreakable digital identity for your work.

1
Upload Your Artwork
Upload a high-resolution photo of your work. We accept JPG, PNG, TIFF, and PDF up to 50MB.
2
Blockchain Hash Generated
A unique SHA-256 fingerprint of your image is created and permanently recorded on the Polygon blockchain.
3
Download Your Certificate
Get a premium printable PDF certificate, a hash card, and a QR card — ready to hand to your collector.
4
Transfer on Sale
When the work sells, register the transfer. The provenance record updates on the blockchain permanently.

A Complete Identity for Every Work

Provenance doesn't just certify the artwork — it creates a living record that grows over time.

The Artwork Itself
The SHA-256 hash of your uploaded image is the fingerprint of the work. Any alteration — even a single pixel — produces a completely different hash, making forgery mathematically impossible to conceal.
Image hash on blockchain
Artist Identity
Your verified Authentica account is permanently linked to the certification. Title, technique, dimensions, year of creation, and artist statement are all part of the certified record.
Creator verification
Edition, Series & Tiraje
Whether it's a unique painting, a limited print run of 10, or a production series of 50 design objects — each piece gets its own numbered certificate. A series of 20 chairs generates 20 individual blockchain records, each marked "Piece X of 20". No undeclared copies possible.

Ownership History
Every time the work changes hands, the transfer is recorded on the blockchain with date, parties, and optional sale price. The provenance record is immutable, cumulative, and publicly verifiable via QR code.
Transferable ownership chain

Three Documents, One Certification

Every certification generates three downloadable assets — for the studio, the frame, and the collector.

SCAN TO VERIFY PUBLIC
QR Verification Card

PDF — QR format
The Record That Grows With Every Sale
When a collector buys your certified work, they create an Authentica account and you register the transfer. The blockchain records the new ownership permanently — creating a living provenance document that follows the work for its entire lifetime.
  • Buyer creates a free Authentica account to receive ownership
  • Transfer recorded on blockchain with date and parties
  • Optional: record sale price for auction provenance
  • QR code always shows the current owner and full history
  • If the collector resells, they transfer again — chain continues
  • Artist retains creator credit permanently, regardless of transfers
