since the wallet is a physical piece of hardware if thrown away or get lost is the assets onboard going to remain safe if the founder know nothing about the key 🔑?
Lost the key and lost your coin forever even nothing is happening about the coin bit you're inaccessible to get hold of the coins, the founder has no access tobit either untill he got the passphrase to accessing the wallet onbthe blockchain because the coins aren't stored onbthe physical wallet materials we see, the hardware is just a means to connect us to the access needed to the blockchain through the keys in it.
