Trezor is a hardware wallet designed to securely store cryptocurrencies and manage private keys offline. Developed by SatoshiLabs, Trezor provides a highly secure and user-friendly way to store digital assets. Here’s a detailed explanation of its features and functionalities:
1. Security Features
Offline Storage
Private Keys: Trezor stores private keys offline, on the device itself, which protects them from online threats such as hacks and malware.
PIN Protection
PIN Code: Users must set up a PIN code during the initial setup, which is required every time the device is connected. The PIN entry process is designed to prevent keylogging attacks.
Recovery Seed
Backup Seed Phrase: During setup, Trezor generates a 24-word recovery seed phrase. This phrase can be used to recover the wallet and its funds if the device is lost or damaged. The seed phrase should be stored securely offline.
Passphrase
Optional Passphrase: Users can add an extra layer of security by setting up an optional passphrase. This acts as a 25th word to the recovery seed, making it harder for unauthorized access even if the seed phrase is compromised.
2. Supported Cryptocurrencies
Trezor supports a wide range of cryptocurrencies, including:
Bitcoin (BTC)
Ethereum (ETH) and ERC-20 tokens
Litecoin (LTC)
Bitcoin Cash (BCH)
Dash (DASH)
Many others
The list of supported assets is regularly updated to include new coins and tokens.
3. User Interface

4. Transaction Management
Signing Transactions

Address Verification
Address Display: Trezor displays the recipient address on the device's screen, allowing users to verify it matches what they see on their computer, ensuring the address has not been tampered with.
