A hardware wallet is a special electronic device that uses a secure chip to generate and store private keys. In the world of encrypted digital assets, the private key is the only proof of asset ownership, so private key security is the most important concern for holders of encrypted digital assets.
Hardware wallets store private keys in a secure chip, completely isolated from the network. By storing in this way, private keys are not exposed to network hackers, greatly reducing the possibility of key leakage or theft.
Compared to software wallets, most hardware wallets have the following features:
- Use secure chips to generate and store private keys
- Completely isolate from the network to prevent hacker attacks
- Have physical buttons and a screen that displays transaction information
- All transactions are signed through the hardware wallet, and the application will not access the private key
Common hardware wallets include imKey, Ledger, and Trezor.
