Frequently asked questions.

Quick answers about proofs, attestations,
verification and integrations.

What’s the difference between a proof and an attestation?

A proof of existence demonstrates that a file or data existed at a given moment (timestamped evidence). An attestation is a verifiable statement (issued by an organization) about a person, document, or fact.

How does verification work for recipients?

Recipients open a verification link or scan a QR code. Stamplr returns a clear result (valid/invalid) plus relevant metadata.

Is Stamplr compatible with the European Digital Identity Wallet?

Stamplr is designed with a wallet-ready approach: structured attestations, verifiable identifiers, and integration-first issuance flows.

Can we run Stamplr on-prem or in a private cloud?

Yes, Stamplr is designed for enterprise deployment models, including cloud and on-premise setups, depending on your requirements.
