Czech company Trezor, developer of the cryptocurrency industry’s first hardware wallet, has also become the first company to develop the cryptocurrency industry’s first hardware wallet. Integrate open source secure element chipThis means you can audit all device information that protects your assets.
This was revealed by company CEO Matej Zak during the Trustless By Design conference. The chip is integrated into the brand’s new model Trezor Safe 7, which was announced during an event attended by CriptoNoticias.
Up until this point, the auditability of Secure Element chips has been a flashpoint in the cryptocurrency industry. Trezor has long been criticized for not building this security measure into its devices, but the company responded that these chips are protected by non-disclosure agreements and represent a black box in the auditability of hardware wallets for users.
However, they bowed to pressure and decided to incorporate safety elements into Safe 3 in October 2023. However, at the same time, he was also working on developing a secret weapon.
The company, through its sister company Tropic Square, part of the Satoshi Labs conglomerate, developed the first open-source secure element chip, TROPIC01. now, They made history by integrating this chip into their new transaction signing device.
According to Kaspersky Encyclopedia, “A secure element is a chip that is protected by design against unauthorized access and is used to run limited applications or store encrypted or sensitive data.”
This chip stores a private key that allows you to sign wallet transactions. By separating the private key on this chip, the device becomes more resistant to brute force attacks. However, this type of attack requires advanced techniques and tools (e.g., high-precision lasers, electromagnetic injection), and therefore requires the physical presence of the attacker.
Because the chip is open source, users have full auditing capabilities and can see everything on the device that stores their private keys.
Apart from TROPIC01, Trezor Safe 7 retains the traditional secondary chip, EAL6+, offering a dual architecture for the safety elements. On top of that, Supports Bluetooth Low Energy (BLE) It features Qi2 magnetic compatible wireless charging and a 2.5-inch high-resolution color touchscreen.
Similarly, it incorporates a LiFePO₄ battery that improves the lifecycle of standard lithium batteries by four times, according to Trezor. This wallet is 62% larger than the previous version, the Trezor Safe 5, and retains that model’s haptic vibration feedback and Gorilla Glass screen.
Bluetooth communications are secured using Trezor Host Protocol (THP), an open source layer that ensures encrypted, authenticated, and private connections between mobile, desktop, and tablet devices.
Preparing for a quantum future
The development of quantum computing is a challenge for Bitcoin, but it is still unclear how this issue will be addressed in the future. However, Trezor Safe 7 takes this issue into account. Supports updates against quantum attacks.
This could mean that Trezor Safe 7 can remain effective against potential attacks in the future.
“Quantum-ready” wallets are designed to maintain operational reliability and security in a post-quantum future. “With its quantum computing-enabled architecture and support for quantum-safe firmware updates, you can trust the integrity of Trezor Safe 7 for years to come,” says the new Trezor Safe 7 section on the company’s website.
For many years I thought quantum computers were the stuff of science fiction, but the pace of innovation is changing that view. In the next decade, Bitcoin and other blockchains will need to transition to post-quantum algorithms. The question is not “if” but “when.” That’s why we built a quantum-ready bootloader into Safe 7. Even in a future where quantum computers are a threat, you can securely update your devices when you need to.

The new Trezor Safe 7 is priced at 249 euros and can be pre-ordered on the Trezor website. Shipping is scheduled to start on November 23rd.
