Tropic Square’s Secure Element Deployed in The Latest Trezor Crypto Hardware Wallet
TROPIC01 becomes the world’s first transparent secure element to power a consumer device, establishing a new benchmark for open-source hardware security.
"We use TROPIC01 in the Trezor Safe 7 wallet to verify authenticity and to encrypt the seed against the PIN. The seed is not stored in any SE; it is encrypted in the main MCU using a key from Tropic Square and Optiga. An attacker would need to compromise all three independent layers to reach it."

The integration of TROPIC01 in Trezor Safe 7 marks the beginning of a broader movement toward auditable and adaptable security across industries.
A New Standard for Secure Hardware
TROPIC01's integration into the new Trezor Safe 7 makes it the first open secure element to be used in a globally available consumer product, setting a new industry benchmark for secure hardware.
Your keys never leave the chip
Signing happens inside, protected from physical attacks.
The chip protects the master key with MAC&Destroy
TROPIC01 protects keys, but can’t stop user mistakes like typing the seed into a fake website.
TROPIC01 provides randomness
High quality random number generator is used to increase entropy during device initialization.
Only verified firmware can run
Secure boot and cryptographically signed firmware verification ensure only trusted software runs.
Protected from physical attacks
TROPIC01 has built-in defenses against side-channel attacks, glitching, and tampering.
"What we’ve achieved with Trezor is more than a product milestone, it’s a signal for the entire hardware industry."
Jan Pleskac
Years ago, while prototyping with a secure chip, developers at Trezor uncovered critical vulnerabilities. Bound by NDA, they couldn’t disclose details, the vendor dismissed the attack as “out of scope”. Out of scope is an attackers' playground.
That experience revealed the inherent risks of closed-source secure chips and sparked the inception of TropicSquare. A new fabless chip company on a mission to fix what’s broken in hardware security.
"We chose the hard way, because anything less wouldn’t cut it for securing private keys to billions of dollars and for other critical applications where security failure is simply not an option."
Instead of locking flaws behind NDAs, we built a secure chip that anyone can attack, inspect and validate. Auditable, open architecture, and free from the black boxes that breed complacency.
We don’t just tolerate scrutiny. We invite it. We encourage independent researchers, academics, and engineers to probe our chips, break them if they can, and push us to continuously improve.
Every attempted exploit drives faster patches, smarter defenses, and stronger hardware. Because security isn’t a static certificate. It’s a living process. One that must evolve as fast as the threats themselves.
