Hardware Wallet Check
Runs offlineCheck whether your device can display what you're signing.
What you are signing
What the device shows
Every hardware wallet displays a plain native transfer in full: the recipient address, the amount, and the network fee.
The only real risk is address substitution by clipboard malware — which is precisely what the device screen exists to catch.
Check before you approve
- The full recipient address, character by character, on the device — not the screen you copied it from
- The amount, including the decimal place
- The network, if your device shows it
A hardware wallet protects your key, not your judgement. It cannot stop you approving something harmful — it can only make sure nothing is approved without you pressing the button. Everything above is about using the seconds before that press.
About hardware wallet check
A hardware wallet keeps your private key off the internet. It does not keep you from approving something harmful — it only guarantees nothing is approved without a deliberate press. What decides the outcome is what the device can display and whether you read it. This walks through each kind of request, what a device typically shows for it, and the specific fields worth checking before pressing confirm.
