Trezor Safe 7 review: a $249 wallet that finally justifies Bluetooth

Trezor put a $249 price tag on the Safe 7, its new top model, and asked buyers to trust that a bigger screen, a wireless radio and a magnetic charging pad earn back the extra cost over the $129 Safe 5. We ordered one, paired it with a phone over Bluetooth and ran coins through it for two weeks before deciding whether that bet pays off.

The pitch: three chips instead of one

Every prior Trezor Safe model leaned on a single secure element from Infineon, certified EAL6+ but sealed under an NDA nobody outside Infineon and Trezor gets to inspect. The Safe 7 adds a second chip, TROPIC01, which Trezor and its manufacturer publish openly enough that outside researchers can audit its design rather than take a certification on faith. A third component, the STM32U5G application processor, handles everything else, so an attacker who wants your seed has to compromise two separately sourced chips working together rather than one.

We cannot independently verify a chip's silicon-level security in a two-week test, and nobody writing a consumer review can. What we can say is that the architecture matches what Trezor documents publicly, and that having a second, openly reviewable secure element is a meaningfully different claim than "trust our audit," which is what every closed secure element amounts to.

Bluetooth actually worked, and that surprised us

We went in skeptical of Bluetooth on a hardware wallet: it is one more radio, one more thing to patch, one more reason a phone-based attack matters. Pairing took under a minute through the Trezor Suite mobile app, and every transaction we sent still required a physical tap to confirm on the device's own screen, meaning a compromised phone cannot approve anything without our hand on the Safe 7 itself. That is the same confirm-on-device model Ledger and Keystone use for their own Bluetooth-equipped wallets, so Trezor is not doing anything novel here, just catching up.

The 2.5 inch, 520x380 touchscreen makes the wireless workflow worth using in the first place. Reading a full Ethereum address or a multi-line Solana instruction on this panel does not require squinting or scrolling the way it does on the Safe 3's tiny monochrome strip, and Gorilla Glass 3 kept it scratch-free through two weeks in a bag with keys.
