Description
Trezor is one of the world’s first and most popular hardware wallets, developed by the Czech company SatoshiLabs. A hardware wallet is a physical device that stores the private keys required to access and manage your cryptocurrency holdings offline, providing a high level of security against hacks, malware, and phishing attacks.
Unlike hot wallets, which are always connected to the internet, Trezor and similar devices offer cold storage, drastically reducing the risk of unauthorized access.
How It Works
- The Trezor device is connected to a computer or smartphone via USB or Bluetooth
- Users interact with the wallet interface (e.g., Trezor Suite or browser extensions)
- Private keys never leave the device—all signing happens internally
- Transactions must be physically confirmed on the device before being sent
- The seed phrase (recovery key) is generated and stored securely by the user, not the company
