TRUSTSIGNAL  ·  PROVE. VERIFY. TRUST.

Prove your records haven't changed since the day you filed them.

TrustSignal issues a cryptographic receipt for every record and anchors it on a public blockchain. When a regulator, auditor, or court asks years later, you can prove it’s untouched — in seconds, without trusting us or anyone else.

WHO IT’S FOR  ·  HEALTHCARE STAFFING

Verified at the source. Altered at the handoff.

symplr, Verisys, and Nursys confirm a license at the source. None of them seal the assembled credential packet during the agency-to-facility handoff — the moment it changes hands. That gap is where fraud lives. TrustSignal doesn't replace the source check; it sits after it, sealing the packet so any facility can prove the file is exactly what the agency sent.

Attach a tamper-evident receipt to every credential packet before it reaches the facility's MSO. The facility calls the verify endpoint and gets mathematical proof the packet is unchanged — no board re-query, no phone call, no manual process. An NFC tap at the credentialing desk binds physical presence to the submission.

HOW A PILOT WORKS

90 days. One workflow. One partner.

TrustSignal sits behind your existing workflow at the ingestion boundary. We seal a single document type, prove its integrity on demand, and the receipts outlive the pilot — and us.

  1. 01
    Collect

    Evidence enters through your existing systems. No workflow change, no new tools for your team.

  2. 02
    Receipt

    A signed, tamper-evident receipt is generated at ingestion — a mathematical proof, not a log entry.

  3. 03
    Verify

    Any time later, a single API call confirms the evidence matches its original sealed state.

  4. 04
    Review

    Your compliance, legal, and audit teams hold mathematical proof of integrity — not just internal logs.

  • 90 days, fixed fee, one-time
  • Up to ~3,000 proofs
  • 25 NFC wallet cards where applicable
  • No IT integration, no workflow change
  • Receipts permanently verifiable, even after cancellation

FOR ENGINEERS

One install. One call.
Your documents never leave.

Extract a feature vector locally and send numbers — not files. Get back a permanent, independently verifiable receipt. Setup is one command and about thirty minutes: no database, server, or queue to provision.

  • Pure Node.js SDK — no Python
