Verify once.
Authorize everything.

Proof is the identity network behind the internet's most important transactions.

Built for the moments that can’t go wrong

From the documents you sign to the agents acting on your behalf — every action is tied to a verified identity, sealed at the moment it happens.

Everything you sign

Signatures and notarizations bound to a verified signer, then sealed so they can't be repudiated.

Everything you do online

Account openings, payments, and logins tied to a real human — not a stolen or synthetic credential.

Everything an agent does for you

Every action an AI agent takes on your behalf is authorized and traceable straight back to you.

Customers share what's needed and nothing more
