Fingerprint your public identity — name, bio, links — and seal it into a live, tamper-evident audit chain with an official timestamp. Put your verification code in your bio. From that moment, anyone can check in seconds whether a profile claiming to be you matches the one you sealed first.
1 · Build & seal your profile
Publish to the public registry. Anyone checking your code will see these profile fields. Untick to seal privately — the checker will confirm the seal and timestamp only, and your details are never stored.
Your profile is fingerprinted with SHA-256 in your own browser. Registration proves this exact profile was sealed first at this timestamp — the strongest public claim to your own words that exists on the open web.

⚠️ This profile is unclaimed.
No seal exists for this code — which means the identity it claims is unregistered and open to AI cloning and impersonation. Sealing yours takes 60 seconds and costs nothing. Tap here to claim your profile now.
