It connects to a computer via a USB via protocol that allows only to send a transaction template to the device and protects the wallet against malware.


The display allows the user to visually verify the payment address and the amount to be sent. In order to proceed the transaction, a physical human interaction (pressing the button) is required.

In layman's terms you can connect TREZOR to an infected computer and still be able to have 100% control over the funds in your device. 


TREZOR uses hierarchical deterministic wallet creation ([[BIP 0032]]) which makes regular backups of private keys unnecessary.

Confirming transaction with TREZOR

TREZOR is a hardware wallet providing security for your bitcoins by virtue of its design while retaining convenience of use. No matter whether you're a beginner or a security-paranoid geek.

Unlike a cold storage (offline storage or paper wallet), TREZOR is also able to send bitcoins in a secure way. Without the need to expose your private keys to a potentially compromised computer.
