Trezor was the world’s first hardware wallet, launched in 2014 by SatoshiLabs in Prague. Its defining characteristic is fully open-source firmware — every line of code is publicly auditable on GitHub, meaning the entire security community can verify that there are no backdoors or vulnerabilities hidden in the software. For security-conscious holders who want complete transparency over what runs on their device, Trezor is the gold standard.

Trezor Suite, its companion desktop and web application, provides a clean interface for managing assets, buying crypto directly through integrated partners, and accessing basic DeFi functionality. The Model T adds a colour touchscreen for easier operation, while the Model One remains the most affordable entry point into hardware wallet security at $69.
