What it can do
How the score breaks down
Each dimension is explained on the methodology page.
Where it is strong and where it is not
✓ Strengths
- Fully open source with a secure element
- Genuinely the easiest hardware wallet to set up
- microSD backup as well as a seed phrase
- Swiss manufactured with a clear supply chain
✗ Weaknesses
- Bitcoin and Ethereum only
- Smaller asset coverage than Ledger
- Less well known, so fewer guides
Incident history
No security breach or significant incident on record.
The Bitcoin-only edition removes all other code from the firmware. If you only hold Bitcoin, that is the one to buy.
Reputation and reviews
A reputation score out of 100, kept separate from the feature score above. It reflects what users actually report over time rather than a star rating scraped on one day.
REPUTATION
85/100
Quietly excellent and under-known outside Europe. Swiss made, fully open source, and consistently praised for how simple the setup is compared with its competitors.

Star ratings change constantly, so we link to the sources rather than printing a number that is out of date the day after it is written.
If something goes wrong
COMMON FIXES

RISK WARNING
Crypto assets are highly volatile and largely unregulated. You can lose everything you put in.

to buy or sell any asset. Do your own research and never commit money you cannot afford to lose.
