Gibt es eine Hardware-Geldbörse, die einen Seed offline erzeugen kann?

About self-custody recovery/backup solutions 100% offline, take a look at the relationship between BIP39 and BIP85. You can retrieve all your child seeds based on your master seed phrase. You can use passphrase as well then use child phrases on any mobile/hardware wallet you feel comfortable with.

The page of the BIP39 Tool of Ian Coleman saved on a USB Drive with Tails offline: https://iancoleman.io/bip39/ then check the box “Show BIP85” + https://tails.boum.org/install/download/index.en.html

In that way, if you like your HWW, you can use it with one of your child phrase so if one child phrase is compromised all your assets are not.

As the trust about firmware is the same concern with all brands, my main point is to think about finding a way to keep your HWW while being free to use other HWWs and never need to expose you master seed phrase + passphrase in your life.

I still think Ledger is a good wallet but I’ve lost faith so I use child phrases and dilute the security risks in other brands.

Segregated wallets allow us to NOT rely on a single brand… without having to mess around with too many recovery backups.

BIP85 in short:
– Watch https://youtu.be/JVuURYQkhxg
– Read this landing page https://bip85.com/
– Listen https://youtu.be/cRRB_WzZpTM
– Play/test it with https://iancoleman.io/bip39/ (check the tiny box “Show BIP85”)

Also for long term “Cryptoasset Inheritance Planning: A Simple Guide for Owners” by Pamela Morgan is a must have. https://www.amazon.com/Cryptoasset-Inheritance-Planning-Simple-Owners/dp/1947910116
This book is amazing!

Doesn’t ledger do this? Just plug it into a wall socket.

I had to generate a new seed (lost old one) with my backup nano s. Used a wall socket usb plug to generate the seed without any issues.

Ahhh? Use a watch only wallet?

I’d recommend getting a Keystone Pro. It’s open source, airgap and has detachable battery functionalities. This keeps the seed phrase generated in the wallet offline forever.

Hey – Ledger devices generate the seed offline inside the secure element of the device. You can surely keep it plugged into your PC.
