Where can I find my Transaction Hash and Seed?

Both are printed in your PDF certificate, the document you download right after your certificate is created. You can also retrieve it at any time by logging into your EMOZ account, where it is regenerated on the fly. In the certificate:

  • The transaction hash is under "Blockchain Proof": the long identifier of the blockchain transaction that recorded your file's fingerprint on Polygon.
  • The seed is under "Secret Decryption Seed (Base64)": the key that decrypts the personal metadata embedded in the record.

How to use them on the verification page:

  1. Enter the transaction hash. This alone confirms that the certificate exists on the blockchain and shows the certificate data.
  2. Optionally add the seed to also decrypt and display the encrypted metadata, such as the owner's name and the ownership declaration.

Treat the seed like a password: only share it with people who should be able to read that metadata. And if you no longer have the document, see What happens if I lose the PDF certificate?
