Trezor Launches Safe 7 Hardware Wallet With Auditable Secure Element

Trezor, the company behind the first-ever hardware wallet, has unveiled the Trezor Safe 7, a device that brings two unusual ideas to consumer crypto security: a fully auditable secure element and a “quantum-ready” architecture.

For years, hardware wallets have faced a paradox. They’re designed to eliminate trust in third parties, yet the chips that secure them — known as secure elements — are typically closed systems. Trezor’s new design challenges that model. 

At the core of the Safe 7 is TROPIC01, a secure element whose design and implementation can be publicly inspected and verified.

The company says the goal is to make security verifiable rather than taken on faith — a principle long central to Bitcoin itself.

Quantum computing and self-custody

The Safe 7 also looks toward the next decade of cryptography. Trezor built the device with a quantum-ready architecture, capable of receiving secure updates once post-quantum algorithms become standard. 

While the timeline for quantum computing’s impact on Bitcoin security remains uncertain, the company’s approach reflects a growing awareness in the industry that long-term self-custody may need to adapt to new threat models.

The wallet uses a dual-chip design, pairing the transparent TROPIC01 element with a secondary EAL6+ secure component to protect against both physical and software attacks. 

Private keys are isolated from the host system, and all transactions must be physically confirmed on a 2.5-inch color touchscreen.

On the usability side, Trezor has moved closer to what modern device owners expect. The Safe 7 supports Bluetooth connectivity, Qi2 wireless charging, and an anodized aluminum body with Gorilla Glass protection. 

The company has also introduced the Trezor Host Protocol, an open-source communication layer meant to keep Bluetooth connections private and verifiable.

Through the Trezor Suite app, users can manage thousands of crypto, trade, and interact with third-party services. A Bitcoin-only version of the wallet will also be offered for those who prefer minimalism and focus.

The Safe 7’s hardware is built for longevity, featuring a LiFePO4 battery rated for four times more charge cycles than standard lithium cells and an IP54 resistance rating for dust and splashes.

Developed by SatoshiLabs in 2014, Trezor is a leader in the industry and was one of the first companies to create a hardware wallet. The name “Trezor” comes from the Czech word for “vault”.
