Minnaars include a digitally-signed Certificate of Authenticity (sometimes referred to as a Token of Authenticity) which is recorded on the Liquid Blockchain. You can find and verify the associated certificate for each Minnaar in its catalog description .
When transferring ownership of a Minnaar, the certificate should always be transferred along with the artwork. Certificates can be received, held, and transferred using a compatible app like SideSwap or Blockstream Green.
Minnaars without the accompanying certificate will not be recognized.
