Verdict

Finally the first line of Trezor products incorporating a secure element has arrived. In our opinion it easily takes the lead in the current Trezor product lineup – in terms of security and portability. Even with the launch of the newer Trezor Safe 5 it’s easily our price/performance winner.

Even though the device uses only two buttons for input, like the Model One did, and does not offer a touch-screen, like the Model T and Safe 5, its on-device recovery, PIN and seedphrase entry are phenomenal. Trezor really did something truly special with the way they handle user input despite the minimalist form factor. At less than half the price of the Trezor Safe 5 it is an easy recommendation.

Device does support the BIP-39 standard in the companion app. The proprietary CoolBitX mnemonic (seed phrases generated using the “on card” option) is based on BIP-39, but does not use the BIP-39 wordlist. Sample code that demonstrates seed and key generation is available in the CoolBitX Mnemonic Github repository.
