Trezor has confirmed a vulnerability in the TROPIC01 chip in its Safe 7 wallet, discovered by Ledger's Donjon security team during a laboratory audit. The company specifies, however, that no crypto or private key can be compromised via this flaw.
In brief
- The TROPIC01 chip, developed by Tropic Square (a subsidiary of Trezor), presents a vulnerability identified by Ledger Donjon researchers in laboratory conditions.
- Its operation requires physical access to the device, expensive specialized hardware and a high level of technical expertise.
- Trezor confirms the absence of cases of real exploitation and ensures that funds remain protected by several independent security layers.
When two competitors cooperate to better secure the ecosystem
Donjon, Ledger's security research arm, successfully circumvented certain protections of the TROPIC01 chip in a controlled laboratory setting. The team then reported its findings to Trezor, leading Tropic Square to identify a related flaw that could expose additional data stored on the chip.
This type of collaboration between direct competitors remains rare in the hardware wallet sector. The episode reminds us of a reality that is often neglected: hardware security relies as much on the transparency of the players as on the quality of the engineering.
Matej Žák, CEO of Trezor, welcomed this approach in an official statement:
I believe the open process by which this vulnerability was discovered, investigated, and disclosed is the model the industry should follow.
What the flaw allows, and what it doesn't allow
To successfully carry out an attack, a hacker would need at least three simultaneous conditions: physically possessing the target device, having expensive laboratory equipment, and mastering advanced technical skills. Suffice it to say that the usability remains very theoretical.
Above all, the vulnerability only affects one layer among several in the security architecture of Safe 7. Trezor insists: even in the event of TROPIC01 being compromised, the private keys and wallet backups are not accessible. No evidence of actual exploitation has been found to date.
This is not the first time that external researchers have found vulnerabilities in hardware wallets, the exercise is part of the normal hardware security audit cycle. What changes here is the public responsiveness and clarity of Trezor's communication in the face of the disclosure.
Ultimately, this episode illustrates two dynamics that deserve attention. First, the robustness of hardware wallets relies precisely on this layered architecture: a compromised chip does not mean a compromised wallet.
Then, Trezor's transparency regarding the conclusions of its direct competitor sends a strong signal to the entire sector. For crypto holders, the rule remains the same: protect your recovery phrase, maintain secure physical access to your device, and follow firmware updates.
