Be careful about hardware wallets manufacturers claiming to be "100% air-gapped" but then requiring to connect their wallets to the USB for firmware upgrades.
Lets, be clear. 100% air-gapped hardware wallets can sign transactions, create/restore a wallet and upgrade the firmware without connecting the device to a cellular network, wifi, Bluetooth, USB, or NFC.
Air-gapped transactions is not enough, wallets need to also offer air-gapped firmware upgrades.
We updated our website to have more correct data.
