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
- Large touchscreen shows full contract call data, not a truncated hash
- Removable SafeCards keep separate wallets physically apart
- Works natively inside MetaMask, Rabby and Frame
- Decodes contract interactions in readable form
✗ Weaknesses
- Desk device, not portable
- Expensive
- Firmware not fully open source
Incident history
No security breach or significant incident on record.
The reason to buy this is the screen. Use it: read the decoded call data before approving anything.
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
78/100
A niche favourite among heavy Ethereum users because of the large screen, which makes reading a complex contract interaction realistic rather than theoretical.
Check current reviews yourself
Star ratings change constantly, so we link to the sources rather than printing a number that is out of date the day after it is written.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
Transaction stuck pendingYour transaction has sat as Pending for minutes or hours and nothing is moving.Transaction failed but the gas was still takenThe transaction reverted, you got nothing, and the fee left your wallet anyway.Token is not showing in my walletThe block explorer shows the tokens arrived, but the wallet shows nothing.I sent tokens to the wrong networkYou withdrew to your address but picked the wrong chain, and the balance is not where you expected.
RISK WARNING
Crypto assets are highly volatile and largely unregulated. You can lose everything you put in.
Nothing on this page is financial, investment or tax advice, and nothing here is a recommendation
to buy or sell any asset. Do your own research and never commit money you cannot afford to lose.
