Wow… nostr:npub17u5dneh8qjp43ecfxr6u5e9sjamsmxyuekrg2nlxrrk6nj9rsyrqywt4tp nailed it regarding analysis of bitcoin address poisoning attacks. This is something hardware wallets could address through UI displaying confirmation of address as either “self” or “non-self.”

AFAIK, no hardware wallets today can tell you during signing the “to” addresses are “yours” or not.

nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 I think would intrinsically understand this problem…but fixing it will be tricky and can be fixed at transaction creation level too, not just on hardware wallet.
