I made a post about my Cold Card quitting on me (replacement on the way), and when it quit working I decided to import my wallet into my older Tangem wallet that I wasn't using anymore. I'm not sure why I did this as I didn't need immediate access to my BTC, I think I just paniced at the thought of not having access to it for the moment? Who knows. Anyways, in order to restore my wallet created on the Cold Card, I of course had to enter my seed phrase into Tangem. That's pretty straight forward and standard for any wallet's recovery process, I know. But what I'm being paranoid about is that Tangem is a phone app. So up until this point I've been completely air gapped with my Cold Card Q, and now I'm not. BitDefender Mobile runs on my phone and I don't do anything crazy with it, but how bad of an idea was it to restore my wallet into Tangem? I'm 100% certain it's the legit Tangem App software, so I'm not worried about some of the fake Trezor Suite desktop software horror stories I've read. Am I being too paranoid here or should I just generate a new seed phrase when my new Cold Card Q arrives? I've never put my seed into any digital form/media(photo, text file, etc, etc). I've got 2 paper backups, and a metal seedplate backup (Keystone Tablet Plus), so the ONLY time it's ever seen something "electronic" was when I restored it inside the Tangem app. What are your guys thoughts?
I don't understand why you did this. As you said in your relevant thread your BTC balance is not on the first Cold Card Q addresses
(which are empty in this case) while Tangem
(currently) allows creation only one account
(with derivation path equals to m/84'/0'/0'/0/0 for bech32). Thus to find you balances on Tangem you would need addresses with last index > than zero. You was aware that such addresses are inaccessible
(they promise to remove such limitation in one of the next releases ) on Tangem. I wonder what was your plot?
