Authentication standard
Four checks before any piece is listed
Each submission is reviewed for materials, documented origin, and matching records before a certificate and linked digital token are issued.
The four-step workflow
From submission to certificate
Material analysis
Step 1 examines composition, surface, and materials to check that the piece matches its description.
Origin verification
Step 2 traces a chain of documentation that links the piece to its recorded origin.
Record matching
Step 3 cross-references the submission against existing records to confirm consistency.
Certificate and token
Step 4 issues a permanent certificate with a linked digital token for secure tracking.
Submission intake
What to send for review
Upload high-resolution photographs, a technical description, and any supporting provenance documents. Submissions are reviewed in the admin dashboard, where approval to list is granted only after authentication is complete.
Submission checklist
Include clear front and detail images, a written description of materials and dimensions, and documentation tracing the piece's origin.
Admins process each authentication and approve items for listing only after all four steps are complete.
