I read about hardware wallets using the forum search but I still have a question about it, 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 🔑?
Do you know how Hardware works? Having a Hardware wallet is because you want to keep your coins offline, you want them to remain that way until you are ready to spend them and at the very launch of anyone you bought, a unique seed phrase will be provided for you which you must keep safe for the future purpose just the way you are asking now if it ever gets lost or stolen by anyone. You should also add an extension of the passphrase so that no one will have access to your coins should incase your seed phrase or recovery phrase becomes compromised.
As long as you follow tips and instructions, you will remain safe with your hardware wallet, you should be also careful of the type of hardware you want to use, don't buy from merchants, order directly from the company and make sure that it is well sealed.
