How it works
01
Drop your file, paste text, or describe your idea. We compute a SHA-256 hash client-side — your content never leaves your device unencrypted.
02
We apply a trusted RFC 3161 timestamp and optionally anchor the hash to the Polygon blockchain, creating a permanent, independent record.
03
Download your certificate, share a public proof link, or generate a dispute evidence pack. Your timestamp is permanent and verifiable by anyone.
