A Trezor executive has pushed back against on-chain investigator ZachXBT after the prominent security researcher publicly described hardware wallets as “complete garbage” for signing transactions and storing cryptocurrency funds. The exchange has reignited debate about the role of hardware security modules in crypto custody.
ZachXBT, known for his investigative work tracking stolen funds and exposing scams, wrote on social media that he does not advise using hardware wallets “for important tasks like signing transactions or storing funds.” The comment sparked immediate reaction from the crypto community, with many users defending hardware wallets as essential security tools.
Trezor, one of the longest-running hardware wallet manufacturers, responded through an executive who argued that the criticism overlooks the significant security benefits these devices provide. The executive emphasized that hardware wallets store private keys offline, protecting them from the malware and remote access attacks that plague software-based wallets and exchange accounts.
However, the Trezor representative also acknowledged that hardware wallets are not a perfect solution and that users must follow best practices, including purchasing devices directly from manufacturers, verifying firmware integrity, and properly storing recovery seed phrases. Recent sophisticated attacks have demonstrated that even hardware wallets can be compromised if attackers gain physical access or trick users into approving malicious transactions.
The debate highlights a broader tension in the crypto security space: while hardware wallets dramatically reduce the attack surface compared to hot wallets or exchange custody, they still require careful operational security from the user. No single security solution eliminates all risk, and the choice of custody method depends on the user’s technical sophistication and threat model.
