Key takeaways:
- Safe 7 features the first open-source secure element chip with tamper protection and no manufacturer NDAs.
- It supports wireless connectivity and introduces a quantum-resistant boot and authentication system.
- Launching at $249, Safe 7 is now available for preorder, with shipping set to begin in about a month.
A new benchmark in hardware wallet security
Trezor has revealed the Safe 7, a hardware wallet built to meet the evolving demands of digital asset storage. The device includes several firsts for the company, including quantum-resilient protection and wireless capabilities. At its core is a secure element chip — Tropic Zero One — that forgoes traditional closed-door agreements in favor of open inspection.
The chip, developed by Trezor’s sister firm TropicSquare, is designed to be verifiable by the security research community. If any tampering occurs, the chip wipes all stored data by default, eliminating the risk of key extraction.
“From day one, Trezor has been open-source. With Safe 7, even the secure element itself is transparent — no NDAs, no secrets. True trust, verified.”
—Tomaš Sušanka, Trezor’s CTO
Safe 7 also integrates a post-quantum secure bootloader and authentication protocol — future-proofing the device against cryptographic threats that may emerge in the next era of computing.
Built for everyday use and long-term durability
Encased in a one-piece aluminum body with Gorilla Glass on the rear, Safe 7 is engineered to resist wear, dust, and moisture. Its IP65 rating ensures protection from common environmental damage. The device also features a 2.5-inch edge-to-edge color display, which is 62% larger than any previous Trezor screen, offering a more user-friendly experience.
The onboard 3.2V LiFePO4 battery was chosen for its safe chemistry and performance over time, even in situations where the device is fully depleted.
“We didn’t compromise. We built the most durable, sustainable, and beautiful Trezor yet,” said Ada Budinsky, Head of Product.
Comparing Safe 7 to earlier Trezor models
While Trezor Safe 5 brought haptic feedback and a colorful screen to the product line, Safe 7 goes further with wireless connectivity, a significantly larger display, and quantum-ready architecture. It also introduces full auditability for its secure element chip — a first in the industry. The more compact Safe 3 remains a cost-effective option, though it lacks the touch interface, microSD support, and advanced security protocols found in higher-end models.
Design options and accessories
Safe 7 will be offered in Obsidian Green, Charcoal Black, and Bitcoin Orange. Buyers will also be able to pair the device with optional accessories, including a privacy screen, flip case, wireless charger, and a multi-purpose protective cover. Encrypted wireless connectivity is standard, giving users the ability to manage their assets without a physical cable.
The bottom line
Trezor’s Safe 7 marks a shift in how hardware wallets approach transparency and longevity. With its open secure element, resistance to quantum threats, and hardened design, the device signals a step forward in securing digital assets in a rapidly changing tech landscape.
