This question is about how standalone a hardware wallet (such as Trezor) is. Or in other words, what other components, if any, does it depend on.
So this is about what other components are needed for the Bitcoins to end in Bobs hardware wallet when Alice wants to send Bitcoins to Bobs wallet address.
So for example, is a hardware wallet dependent on connecting to either
- some software with the wallet address that runs on the PC and connects to the internet, or
- some web application, or maybe a part of the BTC ecosystem, that hosts the wallet address
Or is it possible to send Bitcoin directly to a hardware wallet (such as Trezor) simply by plugging the hardware wallet to a USB port on your PC?
