Thanks for all the info. I would imagine most btc NFC wallets run a similar pattern as you guys? Curious if you know any (you dont have to mention by name if you dont want) that are currently available out there that dont use encryption, and would be vulnerable to tools such a flipper?
It's hard to tell. I don't know that much devices that use NFC, and the only way to know for sure is to review the code (if available) or reverse engineer it (which is more difficult)...
I think you or someone from your team donated a wallet card to a charity auction I ran a few years back. I dont see it in your past posts so maybe it was someone else with Satochip ? Either way it was much appreciated!
That was probably Tibu (
