Common Questions

Before you contact us

A few boundaries that keep the first conversation useful and safe.

What should I include in my inquiry?

Briefly describe what you are protecting, whether you already use self-custody or a hardware wallet, your biggest concern, and whether the request is for yourself, a family, or an advisor-led client.

Do I need to share private information in the form?

No. Do not send recovery words, private keys, passphrases, wallet balances, screenshots of backups, or sensitive identity documents through the contact form.

Can Fortress21 help online?

Yes. Fortress21 is based in Hong Kong and supports Hong Kong, APAC, and US clients online when the engagement can be completed safely without exposing secrets or weakening the custody model.
