Certify your file

Drop any file to create an immutable proof on the blockchain.

Your file stays private - only its SHA-256 fingerprint is recorded on MultiversX.

How certification works

  1. Select or drag your file
  2. A unique SHA-256 hash is computed locally on your device
  3. Sign the transaction with your MultiversX wallet
  4. Receive a downloadable PDF certificate with QR code
