TROPIC01 Becomes the World’s First Transparent secure element to power a consumer device, establishing a new benchmark for open, auditable hardware security.

Prague, Czech Republic — 21 October 2025  — Fabless semiconductor company Tropic Square, today announced a major milestone with the integration of its open architecture secure element, TROPIC01, into the newly launched Trezor Safe 7 hardware wallet. This marks the first time an open and auditable security chip has been deployed in a mass-market consumer device, establishing a new benchmark for transparency as the foundation of trust in hardware security.

Hardware wallet industry founder Trezor leaned on Tropic Square early in the concept phase of its new-generation device to find a chip that was truly open and would provide an unprecedented level of protection for users’ data and digital assets. 

Tropic Square and Trezor are among a new generation of companies challenging the decades-old model of security by obscurity. Their collaboration demonstrates how auditable and verifiable hardware can secure critical endpoints, having now created one of the most secure and forward-looking architectures in the crypto industry.

As connected devices are projected to surpass 31 billion by 2030¹ and cyber threats escalate, decentralized trust and verifiable hardware are becoming fundamental in meeting new security levels, regardless of the application or use case. Auditable endpoint protection is as relevant to hardware wallets as it is to securing personal identity systems, critical infrastructure, embedded AI and other edge applications. The integration of TROPIC01 into Trezor Safe 7 marks the first step toward broader adoption across hardware wallets and other core technology sectors. 

“What we’ve achieved with Trezor is more than a product milestone, it’s a signal for the entire hardware industry that open and verifiable security is the only sustainable path forward,” said Jan Pleskac, CEO and Co-founder of Tropic Square. 

“With Trezor Safe 7, we wanted to set a new standard for hardware wallet security. And thanks to TROPIC01, the world’s first transparent and auditable secure element, our product delivers one of the most robust security architectures in the industry,” said Matěj Žák, CEO of Trezor. “For us it was an obvious approach, one that we envisioned many years ago and that Tropic Square was able to deliver,” he added.

TROPIC01’s design for Trezor Safe 7 introduces the unique MAC&Destroy feature, a mechanism that prevents brute-force attacks by irreversibly limiting PIN attempts and destroying authentication tokens after repeated failures. Combined with TROPIC01’s built-in anti-tampering sensors and physical security defenses, this ensures that secrets remain secure even under physical assault, a critical safeguard for devices that protect digital assets. 

Tropic Square released its flagship chip TROPIC01 in February 2025 and recently moved into full production and worldwide availability. The open design philosophy has sparked a fundamental shift away from the industry’s traditional reliance on blind black box architecture to one that allows device integrity. This new wave of security chips allows manufacturers to verify what runs inside the devices they produce. With TROPIC01, companies can now audit down to the silicon level, ensuring there are no undocumented features, backdoors, or hidden vulnerabilities.

Tropic Square's open security approach and unique security mechanisms align with evolving regulations such as the EU Cyber Resilience Act (CRA), which emphasize transparency, accountability, and open vulnerability disclosure. Tropic Square’s peer-reviewed, continuously improving design model anticipates these changes by making adaptability and community-driven verification core features of its security platform.

“Trust in technology must be earned through a user’s ability to verify what’s beneath the surface.  TROPIC01 does that by allowing device makers to truly see what’s inside their devices and to continuously adapt to new threats. A line of defence that is impossible under closed, proprietary models,” said Pleskac.

TROPIC01 is now shipping globally with next-day delivery, no NDAs, and no barriers. Available on development boards like Raspberry Pi, Arduino, Mikroe, and a new USB-C version you can get production-ready boards and samples today through our networks of partners or via the website.
