Can an NDA be signed electronically?
Yes. An NDA is an ordinary contract with no form requirement, and under article 25.1 of the eIDAS regulation (910/2014) an electronic signature may not be denied legal effect solely because it is electronic.
The NDA is usually the first document in a deal and the one most often left unsigned. The investor wants the numbers on Wednesday, the supplier needs the drawings tomorrow, and the agreement sits in an email thread where nobody remembers who replied last.
A link fixes the tempo. The person signing needs neither a printer nor an account, and you can see in plain language when the agreement was opened and when it was signed.
Why does the date of the NDA matter?
Because protection for trade secrets rests on what you did before the leak, not after. Under section 2 of the Swedish Trade Secrets Act (2018:558) information counts as a trade secret only if the holder has taken reasonable steps to keep it secret.
An NDA signed before the information changed hands is such a step. An NDA that was sent but never came back is not.
That makes the timestamp more than a detail. TRUE Sign records every event on the document, from sending to the last signature, and seals the PDF with a SHA 256 fingerprint written to a blockchain.
