<p>Trezor confirmed a vulnerability in the TROPIC01 chip of its Safe 7 wallet, discovered by Ledger’s Donjon security team during a lab audit. However, the company specifies that no crypto or private key can be compromised through this flaw.</p>

  <h2 class="in-brief--title" id="in-brief">In brief</h2>
  <ul>
   <li>The TROPIC01 chip, developed by Tropic Square (a subsidiary of Trezor), has a vulnerability identified by Ledger Donjon researchers under laboratory conditions.</li>
   <li>Its exploitation requires physical access to the device, expensive specialized hardware, and a high level of technical expertise.</li>
   <li>Trezor confirms no real-world exploitation cases and assures that funds remain protected by multiple independent security layers.</li>
  </ul>

<p>Donjon, Ledger’s security research division, managed to bypass certain protections of the TROPIC01 chip in a controlled laboratory setting. The team then passed their findings to Trezor, which led Tropic Square to identify a related flaw potentially exposing additional data stored on the chip.</p>

<p>This type of collaboration between direct competitors remains rare in the <a href="https://www.cointribune.com/en/taxes-2026-the-complete-guide-to-declare-your-cryptocurrencies-starting-today/" rel="noopener noreferrer nofollow">hardware wallets</a> sector. The episode reminds us of a frequently overlooked reality: hardware security depends as much on the transparency of the actors as on the quality of engineering.</p>
<p>Matej Žák, CEO of Trezor, praised this approach in an official statement:</p>
<blockquote class="wp-block-quote">
 <p><em>I believe that the open process through which this vulnerability was discovered, examined, and disclosed is the model that the industry should follow.</em></p>
</blockquote>
<h2 id="h-what-the-flaw-allows-and-what-it-does-not">What the flaw allows, and what it does not</h2>
<p>To succeed in an attack, a hacker would need at least three simultaneous conditions: physically possess the target device, have expensive laboratory equipment, and master advanced technical skills. Needless to say, <a href="https://www.coindesk.com/tech/2026/06/02/dnp-trezor-says-users-crypto-is-safe-after-ledger-researchers-uncover-chip-flaw" rel="noopener noreferrer nofollow">the exploitability remains very theoretical</a>.</p>
<p>Moreover, the vulnerability affects only one layer among several in the Safe 7’s security architecture. Trezor emphasizes: even if TROPIC01 is compromised, private keys and wallet backups remain inaccessible. No evidence of real exploitation has been observed to date.</p>
<p>This is not the first time external researchers have found vulnerabilities in hardware wallets; this exercise is part of the normal hardware security audit cycle. What is different here is Trezor’s public responsiveness and clarity of communication regarding the disclosure.</p>
<p>Ultimately, this episode illustrates two dynamics worth attention. First, the robustness of hardware wallets rests precisely on this layered architecture: a compromised chip does not mean a compromised wallet.&nbsp;</p>
<p>Second, Trezor’s transparency in response to its direct competitor’s findings 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.&nbsp;</p>
