Authenticity system

Each work carries its own certificate.

Limited edition prints and unique works, physical or digital, accompanied by a verifiable certificate: public code, QR, and verification page. No blockchain; the registry is proprietary, database-backed, and auditable.

Certificate example

Each certificate gathers the work, edition number, issue date, materials, and a unique public code, issued after purchase or manually by the artist.

Generative seal

Each certificate carries this unique seal at the top, with the code engraved in text around it. A closer look — all the art is generated deterministically from the code itself.

Generative seal

Every certificate has a unique seal, generated from its own code.

No two seals are alike. The art is generated deterministically from the certificate code: the same code always produces the same drawing, impossible to forge by chance. Each series has its own shape and palette.

How it works

What is a certificate of authenticity

A verifiable record that links a work to the artist. It applies to limited edition prints, unique works, physical pieces, and digital works. Each certificate has its own public code.

How to verify with the QR code

Each work includes a QR code pointing to a public verification page on this website. The page displays the work, edition number, issue date, and current certificate status.

What a limited edition means

A limited edition defines how many copies of an image exist, for example 17/50. No copies are sold beyond the limit, and each number is assigned uniquely and auditable.

Print, unique work, and physical work

A print is a numbered copy from an edition. A unique work is 1/1, with no reproduction. A physical work may involve printing, MDF, resin, light, and framing, also with its own certificate.

How to recognize a valid certificate

A valid certificate carries a code in the GTX-YEAR-XXXXX format and opens an official verification page within mrgattax.com. Possible states include valid, revoked, replaced, or transferred.

Privacy and support

Collector data is private by default. In case of a lost certificate or questions about authenticity, support is handled directly by the artist.
