What the device shows
Every hardware wallet displays a plain native transfer in full: the recipient address, the amount, and the network fee.
On the device screen
- 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
What a hardware wallet does not do
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. Nothing above is clearance; it is what to read in 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.
Common questions
Why does my hardware wallet show different text than the site?
Because clear signing depends on the device firmware and the contract metadata. Some calls reduce to blind hashes on the screen. This guide names what common devices can show for ordinary transfer, approval and typed-data cases.
What is blind signing?
Approving a hash or truncated data you cannot read as English on the secure screen. It is sometimes unavoidable for complex contracts, and it is also how substituted transactions slip through. Prefer clear signing when the device offers it.
Does this page talk to my Ledger or Trezor?
No. It is documentation of what those devices typically display. Connecting a hardware wallet still happens through your software wallet; this site never asks for a PIN, seed, or device passphrase.
