A hardware wallet is a physical device used to securely store your cryptocurrency private keys offline. It’s a type of cold wallet, meaning it’s not connected to the internet, making it highly secure against online threats like hacking, malware, or phishing
🔐 How It Works:
- The hardware wallet stores your private keys (used to sign transactions) in a secure chip inside the device.
- When you want to send crypto, you connect the device to your computer or smartphone via USB or Bluetooth.
- Transactions are signed on the device itself, so the private key never leaves the hardware wallet or touches the internet.
- The signed transaction is then broadcasted to the blockchain via your computer or mobile device.
✅ Key Features:
- Offline storage of private keys
- PIN protection and recovery phrase for backup
- Tamper-proof and secure chip architecture
- Supports multiple cryptocurrencies and tokens
- Often comes with companion apps (e.g., Ledger Live, Trezor Suite)
