What is Trezor Safe 7?

Trezor Safe 7 Wallet is a hardware wallet with two security chips, Bluetooth connectivity, and quantum threat readiness implementation.

It supports thousands of cryptocurrencies¹ and dozens of networks. Among them are Bitcoin, Ethereum, Ripple, Solana, Sui, Tron, and others.

Let’s examine the wallet from a security perspective.

Now let’s look at the advantages.

Let’s move on to the disadvantages.

We’ll start the review by examining the external characteristics and then move on to the most important part - the new technology inside.

Design and Display

Let’s start with the design. The wallet is made of premium aluminum with a reinforced back panel. Its dimensions are 75.4 mm in height, 44.5 mm in width, and 8.3 mm in thickness, making it the largest wallet in the Trezor family.

On the front panel, you’ll find a 2.5-inch full-color high-resolution touchscreen with haptic feedback that gently vibrates upon touch, much like your smartphone.

The large display makes it easier to read transaction details and provides a more comfortable user experience.

Furthermore, the screen features fully reinforced glass using the patented Gorilla Glass 3 technology, making it resistant to drops, scratches, and even splashes. The power button is located on the right side, and a USB-C port is at the bottom.

Wireless Connectivity and Security

Safe 7 is Trezor’s first wallet with wireless operation. Connect it to a computer or mobile device via a secure Bluetooth connection. Since Trezor always prioritizes security, all Bluetooth connections are protected by the Trezor Host protocol, which encrypts every command and transaction, ensuring no one can intercept, alter, or inject malicious messages.

The wallet remains invisible to unknown devices and only connects to trusted applications via open encryption. This allows you to enjoy secure and encrypted communication. Use it wirelessly with a smartphone or tablet, or simply disable Bluetooth and use a cable connection if you prefer.

Battery and Charging

Safe 7 is also the first Trezor wallet with a battery, specifically a Lithium Iron Phosphate (LiFePO4) one. This battery type offers an excellent balance between safety, longevity, and cost. It lasts 4 times longer than standard lithium batteries, discharges more slowly, and can be fully discharged without damage.

Charging is simple: it features magnetic wireless charging. Just place the wallet on any Qi2-compatible base, and it will lock in for stable charging.

Or, if you prefer, charge it via a USB-C cable.

The wallet is available in three colors: Charcoal Black, Obsidian Green, and a special Bitcoin edition in bright orange.

Security Architecture

Secure Elements

The wallet is equipped with advanced security features to protect your crypto. It includes 2 independent secure elements: Tropic01 and Optiga Trust M.

Together, they create a dual-chip architecture that protects against hacking, brute-force PIN attacks, and counterfeit hardware. Each secure element provides its own layer of protection.

Tropic01 Chip

The first chip is the Tropic01. It was developed by Tropic Square, a company founded by Trezor’s parent group, Satoshi Labs, in 2020, solely to create secure chips that anyone can verify.

Trezor worked on manufacturing this chip for 5 years. It handles PIN protection, device authentication, and secure random number generation for wallet creation.

Optiga Trust M Chip

The second is the Optiga Trust M chip. This is a certified microcontroller with an EAL6+ certification level, the highest in the crypto hardware industry. Both chips work together to secure your funds.

Quantum Resistance

And now for one of the biggest innovations. Trezor Safe 7 is the world’s first quantum-protected hardware wallet. It includes pre-installed hardware designed to support future post-quantum updates, meaning it’s already engineered to resist future quantum computer attacks.

As quantum computing evolves in the coming years, the Safe 7 will be able to receive firmware updates designed for post-quantum cryptography. This is a huge advantage because only devices engineered with this hardware architecture can run these future updates.

Thus, the Trezor Safe 7 is already prepared for the next generation of security.

Software and Compatibility

Alongside this launch, Trezor has also updated its mobile interface, allowing you to securely explore the crypto ecosystem.

Through the app, you can connect to third-party wallets, DeFi platforms, DApps, and NFT marketplaces.

Check your portfolio, send and receive cryptocurrency, and connect your Trezor to popular wallet apps.

Trezor also offers an open SDK so other software wallets can easily integrate with it.

Supported Coins

Trezor Safe 7 supports Bitcoin, Ethereum, and thousands of other cryptocurrencies and tokens.

Seed Phrase and Wallet Import

When creating a new wallet, Trezor Safe 7 by default generates a 20-word recovery seed.

If you already have another hardware wallet, like a Ledger, Coldcard, or another Trezor model, you can safely restore your existing wallet here using standard 12 or 24-word seed phrases. And, like all Trezor wallets, protect your device with a PIN code of up to 50 digits.

Package Contents

Finally, when purchasing the Trezor Safe 7, you will receive: the device itself, a USB-C cable, two seed phrase cards, a quick start guide, a security manual, and some stickers.

Criticism

The claimed quantum resistance of the wallet is more of a marketing advantage than a practical necessity. The threat from quantum computers to current cryptography remains hypothetical and distant in time. Users are paying for a feature that might only become relevant many years from now, while post-quantum cryptography technology itself continues to actively evolve and change, questioning the ultimate effectiveness of a ready-made “hardware” solution.

Despite the premium design and claimed damage resistance, the presence of a large touchscreen and a battery makes the device more vulnerable compared to simpler models. The screen, being a point of physical contact, remains the most fragile element, and the built-in battery degrades over time, potentially leading to the need to replace the entire device after a few years, unlike wallets without a battery that only operate when connected.

About the Company

Trezor is based in Prague and has always been based there. Considering over 50 years of suppression of freedoms by communists and World War II before that, a deep skepticism towards the government grew in the city. These skeptics naturally became interested in Bitcoin and its ethics. From this, the company Trezor grew.

Trezor strictly adheres to an open-source approach.

Anyone can view the source code on Github.
