State boards want proof your plans haven't been altered after you signed off. Stamp-on-Chain gives you that proof.
Your PE seal took years to earn. In the digital age, it can be copied and pasted in seconds.
A junior associate can rip your seal from one PDF and paste it onto another. A contractor can swap plan sheets after you approved them. A board investigation can drag on for months because you can't prove which version was final.
"When a structure fails, the board asks one question: Can you prove you approved THIS exact version of the plans? If your answer is 'the timestamp on our server,' you're exposed."
Digital seals can be copied. Cloud timestamps can be altered. The only real defense is proof that exists independently of your firm, your server, and your IT admin.
Link your verified PE identity to every plan set at the moment of final approval. Proof that survives board investigations, litigation, and decades of document turnover.
Link your PE identity to your plans the second they're finalized. If someone presents an altered version, you can prove it didn't come from you.
Never wonder which version is final. Keep a clean timeline of every revision. If a design is unsafe or a project is canceled, revoke the document and warn anyone trying to use it.
Your plans never leave your device. We secure the proof of your document, not the document itself. You keep full control of your IP while staying audit-ready.
Let your clients, contractors, and state boards verify your plans in seconds — no login needed.
No logins, no passwords, no software. Regulators drag and drop the document into their browser. The check works even if our servers are down.
Even a single changed dimension or deleted note triggers a mismatch. The terminal flashes Green, Amber, or Red.
Stop contractors from building from old plans. If you revoked a plan set this morning, the dashboard shows it instantly.
A public verification tool shows your firm operates with transparency. It says: We stand behind our work so confidently that we give you the tools to prove it.
When you deliver a final plan set, attach the verification receipt. This standard PDF acts as a permanent passport for the document. You signal to your client and the board that you've taken every precaution to protect your seal.
Compliance is usually expensive overhead. Stamp-on-Chain turns it into something you can bill for.
You don't eat the cost. When you deliver a stamped plan set, add a verification fee (e.g., $150) to the invoice. The client pays for mathematical certainty. You get paid to protect your practice.
We work directly with Professional Engineers and firm principals to set up verification wallets. Leave your details below to protect your seal.
