FAQ
No. You can use Uniiku solely as a catalog and documentation system without certifying any work.
Certification with Uniiku seals is optional and applies only to the works that need it. The digital catalog is free and works independently of certification. You can create your free catalog here.
A Uniiku seal is a physical label associated with a specific artwork and connected to its digital information. Each seal is unique and non-transferable: it cannot be peeled off without breaking, and it is statistically impossible for us to manufacture two alike.
A new seal can be linked to a single work in an artist's Uniiku catalog via a digital identifier. Scanning the QR on the seal opens the registered information and its verification status.
You can buy them on Amazon.
The information the artist chooses to associate with the work is stored. This may include technical data, images, authorship, dates, documents, and links.
The information is recorded with a verifiable date and cannot be altered without leaving a trace.
Blockchain acts as a digital notary that guarantees the integrity of the information.
Technically, records are sealed with a verifiable timestamp, allowing proof that the data existed on a specific date and has not been modified afterward.
The work keeps its certification and history, regardless of who owns it.
The new owner can verify authenticity by scanning the seal. Traceability is preserved even if the work changes hands, location, or context.
The Uniiku seal is designed to stay firmly attached and serve as physical proof of certification.
Whenever possible, the seal should be fixed directly to the work, reinforcing the link between the piece and its certification. When attaching it to the work is not possible or could affect conservation or value—such as especially delicate or older works—the seal can go on a paper certificate or another support that accompanies the piece.
If the seal is damaged, broken, or peels off, it stops serving its purpose, just like any traditional physical certificate. In that case, to keep certification active and verifiable, the work must be re-certified with a new Uniiku seal.
No. The chatbot does not value or appraise the work.
Its role is to help you document it correctly: structure the information, write clear technical sheets from the associated images, and make sure common professional fields are not missing.
Uniiku does not aim to replace every existing system, but to offer a more accessible, direct alternative for artists.
In many cases it can coexist with traditional certificates, while providing a key advantage: it permanently links the work and its documentation in a verifiable way, without depending on third parties.
Real situations where Uniiku helps
You do not need a large studio or a technical team. These are everyday moments for independent artists.
Scattered archive
Photos, PDFs, and notes in different folders. Uniiku organizes each piece's documentation into a catalog ready to share.
Artwork about to sell
Before a sale or an exhibition, the artist documents the piece and, if they want, certifies it with a verifiable seal.
Edition or series
When clear numbering and traceability matter, the catalog and seal help explain each copy with precision.
