Timestamp a web page or a received email in one click. Everything is hashed locally in your browser: only the SHA-256 fingerprint is anchored on-chain. The file and the email never leave your device.
Capture any web page as a PDF or PNG and anchor its hash on Polygon. Prove that a page existed, exactly as it was, at a point in time.
A badge in Gmail shows whether a received email is stamped. Stamp it to anchor its hash on Polygon and Bitcoin, then download a self-verifiable proof with the original .eml and its DKIM signature.
Every stamp is verifiable without trusting us. Drop the original file or email on the verify page and it recomputes the hash and compares it with the on-chain anchor.
