Trezor Pushes Back on ZachXBT’s Hardware Wallet Critique
Hardware wallets are designed to keep private keys and transaction signing separate from internet-connected devices, limiting exposure to malware and remote attacks. The debate intensified after blockchain investigator ZachXBT dismissed the products as “garbage” and argued that a dedicated older iPhone could provide sufficient protection for crypto holdings. His criticism challenged a security model widely promoted for the self-custody of digital assets.
Trezor Chief Commercial Officer Danny Sanders publicly rejected that comparison, saying hardware wallets offer an isolated signing environment and an independent trust path that general-purpose consumer devices cannot fully replicate. He also argued that smartphones such as Apple’s iPhone present a broader software attack surface. Reports on the exchange did not identify a specific exploit, loss amount or affected customer, framing the dispute as a clash over security architecture rather than a newly disclosed breach.

The history behind this eventTrezor Discloses Safe 7 Chip Flaw but Says User Funds Are Secure
Trezor Safe 7 is a hardware wallet designed to store private keys for crypto assets offline, with its TROPIC01 secure chip protecting sensitive data. Ledger's security research team found a vulnerability in the chip. Because hardware wallets rely on physical isolation for protection, the flaw raises questions about asset security if a device is stolen.
As of July 19, 2026, Trezor said an attacker would need physical access to a Safe 7, specialized equipment and advanced technical expertise to exploit the flaw. No attacks have been reported, and known user losses stand at $0. The company stressed that funds remain secure but has not announced a timeline for a fix.
