Most of the world still runs on hardware you cannot check, audit or fully trust. Tropic Square is changing that narrative. Together with @ContentWiseInfo , @nitrokey , @RDDLNetwork and @Trezor , we are heading to @TRUSTECH_Event ๐Ÿฎ๐Ÿฌ๐Ÿฎ๐Ÿฑย in Paris. At our booth, you will see what real transparency looks like in practice.

Just in case it is not obvious. Trezor FW is open source so anyone can study how TROPIC01 is integrated. If you prefer talk over self-study, reach out to us with your use case and consult with our team.
Finally... #TROPIC01 is happily placed on the circuit board of the ๐—ง๐—ฟ๐—ฒ๐˜‡๐—ผ๐—ฟ ๐—ฆ๐—ฎ๐—ณ๐—ฒ ๐Ÿณ hardware wallet. The latest flagship hardware wallet from @Trezor. It is the first open security element deployed in a globally available consumer device, created for those who believe that true trust can only be achieved when you can verify what's inside. As our CEO @jan_pleskac said: "๐˜ž๐˜ฉ๐˜ข๐˜ต ๐˜ธ๐˜ฆ ๐˜ฉ๐˜ข๐˜ท๐˜ฆ ๐˜ข๐˜ค๐˜ฉ๐˜ช๐˜ฆ๐˜ท๐˜ฆ๐˜ฅ ๐˜ธ๐˜ช๐˜ต๐˜ฉ ๐˜›๐˜ณ๐˜ฆ๐˜ป๐˜ฐ๐˜ณ ๐˜ช๐˜ด ๐˜ฎ๐˜ฐ๐˜ณ๐˜ฆ ๐˜ต๐˜ฉ๐˜ข๐˜ฏ ๐˜ซ๐˜ถ๐˜ด๐˜ต ๐˜ข ๐˜ฑ๐˜ณ๐˜ฐ๐˜ฅ๐˜ถ๐˜ค๐˜ต ๐˜ฎ๐˜ช๐˜ญ๐˜ฆ๐˜ด๐˜ต๐˜ฐ๐˜ฏ๐˜ฆ, ๐˜ช๐˜ต ๐˜ช๐˜ด ๐˜ข ๐˜ด๐˜ช๐˜จ๐˜ฏ๐˜ข๐˜ญ ๐˜ต๐˜ฐ ๐˜ต๐˜ฉ๐˜ฆ ๐˜ฆ๐˜ฏ๐˜ต๐˜ช๐˜ณ๐˜ฆ ๐˜ฉ๐˜ข๐˜ณ๐˜ฅ๐˜ธ๐˜ข๐˜ณ๐˜ฆ ๐˜ช๐˜ฏ๐˜ฅ๐˜ถ๐˜ด๐˜ต๐˜ณ๐˜บ."

What an unforgettable event ๐Ÿš€! This week @Trezor launched its new flagship, the Trezor Safe 7, setting a new standard for hardware wallets and we were part of it all! Seeing our product #TROPIC01 play a key role in shaping the next generation of secure devices was a proud moment for our team ๐Ÿค˜. From backstage to the main stage, and throughout the experience room, it was heartwarming and inspiring to meet such an amazing community ๐ŸŒ. The energy and enthusiasm definitely gave us a boost. Huge thanks to everyone who made this event so special! #trezor #TS7 #satoshilabs #secureelement #wallet #HWwallet #noobscurity

I have no words for the incredible networking and chilled atmosphere at #oSC25.
Sometimes the events we attend are corporate. Sometimes, theyโ€™re filled with real people building solutions right at the edge of the problemโ€ฆ ย They are the people on the front lines of everything the industryโ€™s end users eventually see. Tropic Square is at OpenSUSE 2025 in Nuremberg, surrounded by developers, tinkerers, and open-source builders who care about whatโ€™s inside their hardware. If you're not interested in #opensource and you're not near Nuremberg... you can skip this. But if you are, hereโ€™s what weโ€™ve brought to the table: ๐ŸŒด TROPIC01 โ€“ the worldโ€™s first Secure Element with an open architecture, down to the silicon. โŒ No blobs. .โŒ No NDAs.โŒ No hidden cores What weโ€™ve got: โ€ข ย A new USB devkit (this is a dev tool, not a polished product) โ€ข Real crypto offload: Ed25519, P256, RNG, encrypted key storage, and our Mac-And-Destroy PIN engine โ€ข Working demos: Secure Boot and a minimal HSM built on TROPIC01 What youโ€™ll do: โ€ข ย Bring your laptop โ€ข Clone and compile the firmware repo โ€ข ย Walk away with a devkit This is about security you can verify, not just trust. Weโ€™re not selling a black box. Weโ€™re handing you the tools and asking: what will you build? Join our workshop led by our firmware rockstar @poldacz951 And if youโ€™re wondering why open hardware matters, catch @jan_pleskac's keynote โ€œOpen Source is no longer just for softwareโ€ย June 27, 13:00 CET More details here: events.opensuse.org/conferenโ€ฆ Letโ€™s stop hand-waving and start shipping hardware we can all inspect.

It was incredible journey for @tropicsquare since first @BTCPrague in 2023. I remember "building bridges" theme of the conference. List of great innovations and inventions with roots in Czechia with little note about Tropic Square,"chips coming soon..."
BTC Prague was ๐Ÿ”ฅ.โ€ฆ and the conversations confirmed what we already know: You can't build a decentralized future on black-box hardware. What we heard from builders, hackers, and engineers: โ†’ We need auditable secure elements โ†’ We need chips aligned with Bitcoin ecosystemโ€™sย values โ†’ We need to verify everything, including hardware TROPIC01 is ready and it's already in the hands of those shaping the future of secure, decentralized systems. Did you miss us in Prague? No worries, you can still get hands-on. Order our fresh Dev Kit, try TROPIC01 in action and learn how to build real trust, at the silicon layer. tropicsquare.com/tropic01-saโ€ฆ #BTCPrague2025 #TROPIC01 #DecentralizedSecurity #DontTrustVerify

CRA - Cyber Resilience Act - if you are a vendor of electronic product with "digital element", what is your approach to compliance?
According to Statista's Market Insights, the global cost of cybercrime is projected to reach an astonishing $13.82 trillion by 2028, underscoring the urgent need for stronger cybersecurity across industries. To address this and other cybersecurity concerns, the European Cybersecurity Resilience Act (#CRA) introduced new regulations for connected products, software, and their remote data processing solutions. This means that electronic device manufacturers now need to comply with a cybersecurity certification framework to protect their products and customers. Our TROPIC01 #SecureElementย is #SecureByDesign, providing features like: -Secure Boot -Secure Firmware Updates -Key Management These are some of the essential features required for CRA compliance. Contact our teamย to learn more and ensure your products meet the highest security standards. tropicsquare.com/contact-us #CyberSecurityResilienceAct #TropicSquare #DigitalSecurity #TROPIC01 #Compliance #CyberResilience #CRA

Great setup in Prague. Thank you @BtcPrague. If you still can make it, see you at @satoshilabs booth.
[SPEAKER ANNOUNCEMENT] @jan_pleskac is a leading specialist in chip design, architecture, and hardware security. He built the technology team at @TropicSquare from scratch, and he leads it since. Together they are developing the transparent and fully auditable TROPIC01 (TRuly OPen Integrated Circuit) chip with the goal of bringing it to market in 2025. In addition to building Tropic Square, Jan is involved in activities of the community around chip design, embedded firmware, and security.
