Prove a document existed — exactly as it stands.

Tamper-proof, third-party verifiable

One click on any document generates an irreversible cryptographic fingerprint and anchors it to a public distributed ledger. From that moment forward, the document's exact state at that exact time is mathematically provable — by you, by opposing counsel, by a judge, by anyone.

The proof doesn't live inside Pasquio. It lives on infrastructure no single party controls, designed to outlast our platform, your firm, and the careers of everyone reading this.

The Certificate of Integrity

Every confirmed certification produces a professionally-formatted PDF certificate suitable for filing, attaching to affidavits, or sending to opposing counsel. It includes everything a third party needs to independently verify the proof — without an account, without Pasquio, without trust in any single party.

• Court-ready language drafted with admissibility in mind.
• Independent verification instructions any technically-literate party can follow.
• Lifetime validity — the proof never expires and never requires re-anchoring.
• Permanent record tied to your matter and visible only to those you grant access to.

Why it matters

“When did your client first sign this?” “Was this document altered after delivery?” “Prove this email existed before the litigation hold.” These questions used to require expert witnesses, forensic analysis, and uncertain outcomes.

Pasquio answers them with a single page of mathematics no one can argue with.
