Ummmm... Not sure what you're talking about. What you can do is generate a new seed on the jade. Make a note of the identifier. Then restore the wallet on electrum or sparrow. See if the identifier matches. If it matches then you can probably trust the Jade so start again with a new seed. Consider using a passphrase too.
Yeah that is of course a great idea… Then I might even pay for something I need soon online from the Jade wallet, before going high in percentage with it! I’m just super paranoid about getting locked out, way more than being hacked since this is on Linux :-) Heck, I’ll try to get it going on this Pinephone I have lying around!
