Watch the film

When you can't trust what you see, replace “trust me” with proof anyone can check.

A photo used to be proof. Not anymore. Here's what StateNull does about it — sealed capture, verification anyone can run, and Trust-E agreements between two people — in plain language, and nothing but the truth.

🔒 Sealed at capturePhotos, scans and PDFs are sealed on your device the instant they're taken — offline, nothing uploaded.

🔎 Verify with mathAnyone can re-check a sealed file in a browser or fully offline — no account, no trusting us.

🛡️ Post-quantum signatureA hybrid classical + default-on post-quantum signature (ML-DSA-65 / NIST FIPS-204). Change one pixel, the seal breaks.

🤝 Trust-E agreementsTwo people sign the same terms with their own keys — time-locked, non-destructive, verifiable offline. A digital handshake for cases and commitments.

⚖️ Honest by designTamper-evident software, designed to support legal & compliance workflows — not a court, notary or legal service.

In the spirit of the film: the narration is a synthetic (neural) voice, and every claim here is what ships today — anything on our roadmap is labelled as roadmap elsewhere on the site. StateNull is tamper-evident, independently verifiable software; it is not a court, notary, legal or law-enforcement service, and makes no guarantee of legal admissibility.
