Can't the matter be made so that the hardware wallet companies use transparent bodies so that when the user checks himself, at least the warranty will not be lost?
Interesting idea, I think some hardware wallets have released transparent edition, i don't know how much effective it is to prevent tampering though. One thing you need to remember, not everybody able to distinguish which device got tampered and which aren't.
And at the same time, what measures can the government take for this?
For example, will no one take responsibility for the users who lost their assets due to the firmware of hardware wallets? Can the regulator do anything here?
And if tampering is done by any official reseller, are the wallet providers completely exempt from liability? Then I think the government should cut off the reseller process or make the wallet providers take responsibility in case of any bad incident.
Historically, these kind of thing always ended up with civil lawsuit, I don't know what's going to happen to ledger, but this tampering honestly different than simple firmware exploit.
Maybe the listing of CryptoBilis as authorized reseller in Ledger's website can be a strong legal claim for a lawsuit.
