Ledger Uncovers Vulnerability in Trezor Safe 7; Trezor Assures User Funds

Key Facts

1Ledger's Donjon team discovered a laser-based hardware vulnerability in the TROPIC01 chip used in the Trezor Safe 7 wallet.

2Trezor stated that the vulnerability does not put user funds at risk and the wallet remains secure.

Amid intensifying competition over security standards in the crypto sector, Ledger's Donjon research team has identified a hardware vulnerability in the rival Trezor Safe 7 wallet. According to reports, the discovered flaw involves a laser-based attack vector targeting the TROPIC01 chip used in the device. For its part, Trezor confirmed that the vulnerability does not pose an immediate risk to user funds, emphasizing that the wallet remains a secure method for storing digital assets.

These findings come after Trezor launched the Safe 7 in late 2024 to bolster security via the TROPIC01 chip developed by Tropic Square. Compared to previous security incidents, this type of physical attack requires advanced laboratory equipment and direct access to the device, making its execution against average users highly unlikely according to cybersecurity experts. This technical rivalry between Ledger and Trezor is part of a long-standing battle for dominance in the cold storage market, which continues to grow alongside crypto adoption.

Traders should monitor any firmware updates Trezor may release to address this technical flaw in the near future. Looking at the economic calendar, markets are awaiting the U.S. Core PCE Price Index release on May 28, 2026, which could impact overall risk appetite in the cryptocurrency market. Physical security levels remain a critical factor in assessing investor confidence in self-custody tools.
