Verify a signed agreement
Every agreement Vaultera seals carries a tamper-evident certificate, and a timestamp from an independent authority. Check the envelope ID printed on it, or drop the signed PDF below — entirely in your browser, and nothing is ever uploaded.

Paste the envelope ID from your certificate page, or choose the PDF you were sent.
Never uploaded. Your browser hashes the file on your device, and only that fingerprint is sent to us.
What this proves
That the file is byte-for-byte what Vaultera sealed, and that the seal is a real certificate rather than a claim — its public half is right here on this page for anyone to check independently.
