Trezor executive responds to ZachXBT: A single hardware wallet is not the best solution for the high-risk scenario, but it should not be dismissed outright

Trezor’s Chief Business Officer Danny Sanders responded to on-chain investigator ZachXBT’s claim that hardware wallets are “utter trash,” saying that software or firmware updates may indeed affect urgent and large transactions, but this criticism is mainly aimed at professional users who manage large amounts of assets and shouldn’t be used to dismiss all hardware wallets. ZachXBT previously recommended using a standalone iPhone that serves no other purpose to store assets and sign transactions. Sanders said a standalone iPhone can be part of a more advanced security solution, but its features—such as Wi‑Fi, Bluetooth, cellular networks, and iMessage—also expand the attack surface; for ordinary users, hardware wallets can still enhance security by isolating private keys and independently verifying transaction information on a separate screen. Tornado Cash co-founder Roman Storm was more aligned with ZachXBT’s suggestion and called on mobile wallets to support BIP39 additional passwords and offline signing. (The Block)

The core advantage of a hardware wallet is the isolated private keys and on-screen verification; the iPhone is too complicated.

They each have their pros and cons—just choose what suits you best.

I think this discussion is quite meaningful. It reminds us that no security solution is absolutely perfect, and we should choose the one that best fits our own usage scenarios.

Trezor executives’ response is practical: it acknowledges that updates may affect large transactions, but it doesn’t outright deny everything. An independent iPhone sounds great, but in everyday use it’s hard to achieve complete isolation, and Apple’s closed system is also not 100% secure.

Hardware wallets are still necessary for ordinary people; the iPhone-based solution has too high a barrier to entry.
