What is a Hardware Wallet?

A hardware wallet is a physical device designed specifically to store cryptocurrency private keys offline. By keeping your keys completely disconnected from the internet, hardware wallets provide the strongest protection against hackers, malware, and online attacks.

How Hardware Wallets Work

Key Security Features

  1. Offline storage: Private keys never touch the internet
  2. Secure element: Specialized chip protects key data
  3. Transaction signing: Signs transactions on-device
  4. PIN protection: Physical access requires authentication

Transaction Process

  1. Create transaction on computer/phone
  2. Send unsigned transaction to hardware wallet
  3. Device displays and signs transaction offline
  4. Signed transaction sent back to broadcast
