Anonymous blockchain researcher ZachXBT criticized Ledger hardware wallets, calling them “complete trash” and advising followers not to use them for storing crypto assets or signing important transactions.
ZachXBT's main complaints about Ledger
- Frequent updates that change the interface and sometimes disrupt basic device functions.
- No evidence of compromised private keys, but the detective did not present specific facts of hacks or data leaks.
Suggested alternative
ZachXBT suggested using a separate iPhone exclusively for crypto operations. He believes this approach reduces the risk of malware infection and clicking on phishing links.
Trezor representative's position
A Trezor representative using the pseudonym Danny disagreed with this position.
- An iPhone is a general-purpose device that is more susceptible to hacker attacks.
- If the smartphone is compromised, an attacker could change the address or amount of a transfer without independent verification.
- Generating seed phrases on smartphones is unsafe due to cloud backups, screenshots, and clipboard access.
Hardware wallets, according to Danny, provide a more isolated environment for signing transactions, making them more secure compared with smartphones.
Recently, Ledger Live was renamed Ledger Wallet, and on June 11, version 4.8.0 was released with a hardware transaction signing feature that isolates private keys from internet-connected devices.
Previously, Ledger analysts discovered a vulnerability in competitor Tangem, resetting the password of a card wallet using a laser pulse in laboratory conditions.
The choice between a hardware wallet and an isolated smartphone remains with the user, but experts agree that security depends on proper use of the device.
