A transparent and auditable secure coprocessor

Transparent and auditable for
better hardware security

Designed for security

We tailor our chip to integrate into and enhance embedded security systems.

Transparent solutions

We share our results to welcome collaboration towards finding better solutions.

Unique in the market

We diverge from the industry’s practice of keeping technical details a deep secret.

functional Overview

TROPIC01 is the first of our secure element series. It supplies and stores the cryptographic keys of your embedded system.

We use dedicated secure HW engines to provide cryptographic algorithms, a set of sensors for anti-tampering, and design practices to protect against a wide range of attacks.

Implementing TROPIC01 into your system protects your assets, and offloads your MCU from cryptographic functions.

Reduce your vulnerability, and allow your MCU to focus on running its main functions.

"TROPIC01 will simplify the way we implement data protection while aligning our vision of open and transparent security."

Marek “slush” Palatinus

CEO, SatoshiLabs

"Tropic Square has a team of passionate, trustworthy experts. And that is what matters from the team delivering a security solution - the right people on the right mission."

Pavel Hübner

CTO & Co-founder, HARDWARIO

How can you trust a design that you or independent security experts cannot audit themselves? Traditional hardware security solutions are behind NDAs and require your blind trust.

We offer secure chips with our core designs open for public inspection and the ability to share the results.

Trust in what you can verify as a community.


TROPIC01 is still in development. Tropic Square reserves the right to make changes, corrections, enhancements, modifications, and improvements to products at any time without notice.
