A hardware wallet is a physical device designed to manage and protect the private keys of holders and users based on a secure chip. It is currently the least vulnerable physical device adopted by users to manage and protect blockchain digital assets, except for personal negligence or subjective reasons.
The hardware wallet’s on-chip software environment is offline and is currently the most effective place to store digital assets against hacking.
When a user opens and creates a wallet, the hardware wallet is responsible for generating the private key (the firmware is signed and verified by the device, preventing fake wallets from generating a private key known to the user by hackers), saving the private key (offline environment, preventing hackers from stealing the private key), confirming the signature on the asset transaction, displaying the content of the transaction for the user to check and confirm (preventing hackers from hijacking and replacing the receiving address)
