FAQs
Only the user has access to their Zero-Knowledge Vault and can initiate the recovery process by requesting a new card. This requires access to their email and mobile phone. The keys are always generated on the secure element of the card and cannot be extracted in any way. Your keys are completely private and solely yours. Even if eSignus is potentially requested by a government or law enforcement to do so, we at eSignus can not recover anything.
Your security is our top priority. That's why one component of your backup is stored offline in Hardware Security Modules (HSMs) during the card's manufacturing, while the other component is under your control in a Zero-Knowledge, open-source software-based Vault.
If you want heirs for your crypto funds, you must give them a Backup Card. The next step is for your heirs to get access to your phone line as access to their inheritance.
They can not use the HASHWallet Link card before its initialization, so they will need access to your email (which you might not have given anyone) or phone line. This way, they will only have access to the crypto funds after your death.
No problem, ask for a backup card from our app. You can access to this option from the front page. Tap over the three points icon over the representation of your HASHWallet Link card, and voila, here you have a shortcut to request your backup card. Rest assured, even owning your card, no one can access your keys. Your crypto assets are completely secure.
As easy as installing a new HASHWallet Manager App on your new phone. Once installed, identify yourself with your email or phone number, and your HASHWallet Manager is back. Now add your HASHWallet Link cards, and you will have the same configuration as before, at least as the last upload to the eSignus Backup Center. It is no more than 5 minutes.
