Just saying, why use this at a merchant? There's no reason to so just don't. And what if you accidentally use an address you just have away the private key for?
Having said that, I love this for personal use and hopefully version 2 will support private key transfer over a segregated nfc chip.
What are you trying to say here?
I see no reason
not to use a Trezor at a merchant. Are you just typing random crap?
Unless you reuse the seed words there is no way to ever access
any private key from the Trezor.
It is impossible. Again, are you just typing random crap?
Why on Earth would you want a way to transfer private keys from your Trezor?
The entire purpose of the Trezor is to keep your private keys safe, segregated from all other electronic devices, and totally secure.
Conclusion: You are just typing in random crap to increase your post count.
