One simple signing flow, for documents that matter

Send, sign and seal in one place. Your counterpart opens a link, signs on any device, and the finished PDF carries its own proof. Every electronic signature is legally binding and takes under ten minutes from upload to sealed.

1

Send in minutes

Upload a PDF, add recipients and place signature, date, name and text fields exactly where they belong.

2

Sign without friction

Recipients open a secure link, review the document and sign on phone or laptop.

3

Seal the proof

TRUE seals the final PDF with its Proof of Signing: timestamps, event trail and tamper evidence.

Security with proof, not just a signature.

Encryption protects a document at origin. A blockchain seal proves what was signed and that nothing changed afterwards. Every signed document is anchored on a public blockchain, so the proof is permanent and independent of us.

Sealed PDF with TRUE stamp and a Proof of Signing.

Anchored on public blockchain. The document fingerprint can never be altered, not even by us.

Impossible to fake. A changed file fails verification instantly.

Anyone can verify. Free, no account needed.

Security first → how every layer works
