Sort of like a ledger or cold card but a phone as well?

Or is this impossible and we will always need dedicated hardware that is separate from devices like phones and computers for security reasons when it comes to large amounts of coin?

Is there a way to add hardware into a phone that is separate from the phone itself but can still interact with it from the inside to sign transactions and truly keep your bitcoins in your phone?

And if someone stole the phone, they still have to unlock it with possibly a passcode, Face ID, Touch ID, and any other walls of security such as passwords to open apps.

I’ll have plenty of time to restore a wallet real quick I guess while the monkey whole stole my phone tries to get inside it. That’s if he knows there’s crypto on it to begin with. Then again, a crypto phone would make any thief more likely to assume there are coins on it versus coins not being on it.

The war on OpSec when it comes to phones is never ending because every human has one lol.

Thanks guys. Much love.
