BlockBeats News, July 18th. In response to on-chain investigator ZachXBT's previous statement that "all hardware wallets are garbage and not recommended for signing transactions or storing funds," Trezor's Chief Commercial Officer Danny Sanders made a response, believing that this evaluation is too one-sided.

Sanders acknowledged that software or firmware updates of hardware wallets may indeed affect urgent operations such as high-value transactions, and that the current products still lack in security and usability. However, he stated that the scenario described by ZachXBT mainly applies to advanced users managing large assets, where a single hardware wallet itself is not the best solution, so this cannot be used to deny the entire category of hardware wallets.

Sanders also pointed out that including an iPhone dedicated to signing and storing assets in an advanced security solution has certain value. However, compared to hardware wallets, phones have a larger attack surface due to features such as Wi-Fi, Bluetooth, cellular networks, and iMessage. At the same time, hardware wallets are equipped with an independent display screen for users to verify transaction information before signing, making it still the strongest self-custody solution for ordinary crypto users.

Furthermore, Roman Storm, co-founder of Tornado Cash, partially agrees with ZachXBT's view, noting that current mobile wallets lack support for BIP39 Passphrase and Air-gapped Signing, and suggesting that wallet developers promptly add these security features.
