What you need
The device new and sealed, its cable, an up-to-date smartphone or computer, and above all a durable medium on which to write the seed phrase. A steel plate is better than the cardboard card supplied in the box.
Guides & tutorials
The first start-up is the most critical moment in the life of a hardware wallet: this is when the keys are born and when the backup is decided. Every guide follows the manufacturer's official procedure, step by step, with the points of caution that the manuals leave unsaid.
Preparation
Initialisation creates keys that nobody can regenerate on your behalf. Meet these three conditions before unboxing the device: they prevent the vast majority of unpleasant surprises.
The device new and sealed, its cable, an up-to-date smartphone or computer, and above all a durable medium on which to write the seed phrase. A steel plate is better than the cardboard card supplied in the box.
Alone, in a closed room, out of view of any camera — including the one on your own phone and home security cameras. No screen sharing, no video call running in the background.
Between 5 and 12 minutes depending on the model, but do not put yourself under pressure. An initialisation interrupted at the wrong moment has to be started again from scratch — a quiet quarter of an hour is better.
The library
Every guide follows the manufacturer's official procedure. Filter by brand or search directly for the name of your device.
What next?
An initialised wallet is not yet a reliable wallet. These three checks turn a configuration that “looks like it works” into a device you can count on.
Reset the device and restore it from your paper or steel backup. It is the only way to know whether you wrote the words down correctly, in the right order. A backup that has never been tested is not a backup, it is an assumption.
A few euros are enough. The round trip validates the whole chain: receiving an address, checking that address on the device screen, signing, broadcasting. You will know exactly what a normal transaction looks like — so you will spot an anomaly.
Copy the phrase onto a durable medium and split it between two physically separate locations. Destroy every intermediate draft. If you have enabled a passphrase, it belongs somewhere other than the seed phrase — otherwise the two fall together.
Frequently asked questions
Certification, connection type, battery life, compatibility, backup method: the comparison tool puts these criteria side by side across the whole range, so that your choice starts from how you will actually use it.
Self-custody calls for rigour: follow these guides closely and always check the procedures against the manufacturer's official documentation. Never share your seed phrase, with anyone.
