How to certify an artwork step by step
Create your free catalog, apply anti-counterfeit seals, and share verifiable digital certificates with no commissions or intermediaries.
Create your free studio inventory
Register your artworks in Uniiku at no cost. Our intelligent assistant helps you structure clear technical sheets with dimensions, technique, images, and authorship context. From the third artwork on, much of the data autofills.
Get your anti-counterfeit label for paintings
Buy Uniiku seals by unit or in packs on Amazon, only when you need them. Each seal is a high-security physical label with a unique identifier that is destroyed if someone tries to peel it off.
Link the seal with a simple scan
Open your phone camera and scan the seal's QR code to link it to the chosen work in your inventory. In a moment, the physical piece and its digital record are permanently connected.
Verify and share with full transparency
Any gallery or buyer can scan the QR to open the official record, check the unalterable registration date, and verify authorship. If the work is sold, the history travels with the piece.

FAQ about certification
No. You can use Uniiku only to create and organize your catalog and free studio inventory. Certification with physical seals is fully optional and applies only to the works you choose to protect or put up for sale.
Each Uniiku seal is an anti-counterfeit label for paintings and prints made with a self-destructive substrate. If someone tries to remove or peel the seal, it breaks apart and becomes unusable, preventing it from being transferred to another work.
The certificate includes the information documented by the artist: title, dimensions, technique, detailed images, year of creation, and the integrity timestamp on the blockchain.
Certification is tied to the physical piece, not to an account. Whoever buys the work only needs to scan the seal to check authenticity and access the official history.
