What is a hardware wallet?
A hardware wallet is a hardware device for the management and protection of digital assets, which can store the private key of the digital asset in a separate secure chip, isolated from the network. Hardware wallets are cold wallets and are one of the most secure ways to manage and protect digital assets as they are not connected to the network, thus eliminating hackers from accessing the private key over the network.
1. a separate secure chip is used to generate and store the private key.
2. off-network and keep away from hackers
3. having physical buttons and screens to display information
4. transactions are signed by hardware wallet, so software applications cannot directly access the private key.
The private key must be kept safe in any device, and must be protected against theft and loss.
