Instantly Verify Professional Engineer Stamps
StampLedger is the secure digital ledger that municipalities use to verify PE stamps in seconds, not days. Blockchain-secured, fraud-proof, and court-admissible.
The PE Stamp Verification Problem
Current verification methods are slow, expensive, and fraud-prone. Municipalities and engineers deserve better.
Slow Verification
Building inspectors wait 2-3 days to verify PE stamps by calling state boards. Projects stall while paperwork sits on desks.
Fraud Risk
Fake PE stamps are easily available online. Recent case: a contractor used fake stamps for 200+ buildings in California.
Manual Process
Paper-based verification is error-prone. No way to verify if a PE had insurance at the time of stamping.
The Cost: Municipalities spend $500-2,000 per stamp verification in staff time. Fraud cases cost millions in liability.
