Trezor Trezor Safe 3
A plan byTrezor
Trezor, made by SatoshiLabs (Czech Republic), is the first hardware wallet ever sold and one of the most respected for transparency: firmware and design are open-source and auditable. The current lineup starts with the Safe 3 (≈€79) with an EAL6+ certified secure element and two buttons, up to the Safe 5 (≈€169) with a colour touchscreen and haptic feedback. Devices are managed through the Trezor Suite app (desktop and web) and support thousands of assets. The legacy Model One and Model T have been discontinued.
