You upload
A single PDF. TRUE reads the pages and captures the cryptographic fingerprint of the document as-is.
TRUE Sign takes any PDF, has your counterparty sign it with BankID, Freja or eIDAS, and returns a sealed original anchored on public blockchain. The proof travels with the document. Verifiable in seconds, for as long as it matters.
Built on the same authenticity engine KTH, Karolinska and Handelshögskolan use to issue verifiable diplomas.
Three steps from upload to a sealed original your counterparty can still verify years from now.
A single PDF. TRUE reads the pages and captures the cryptographic fingerprint of the document as-is.
Every signer identifies themselves with BankID, Freja or eIDAS. Real identity, real timestamp, bound to the exact bytes on the page.
The sealed PDF is anchored on public blockchain and lands as a TRUE original. Verifiable directly from the document, no login, no lookup.
An e-signature only lasts as long as the vendor that stored the audit trail. If they close, if they lose the log, if the signature policy quietly changes, your proof is gone with them.
TRUE Sign anchors the hash of the sealed document on public blockchain. Anyone can verify the signature and the exact byte-for-byte contents of what was signed, independent of us and independent of any platform.
Together with Örebro University, TRUE is developing eIDAS-aligned electronic sealing so signatures meet EU trust services standards across all 27 member states.
The same authenticity engine powers a full family of tools for issuing, storing and verifying documents. Pick the one that fits what you need to prove.
Sign contracts with real identity. Every sealed PDF is verifiable directly from the file, forever.
