Trezor Unveils ‘Quantum-Ready’ Safe 7 Hardware Wallet

Trezor has launched a new version of its hardware wallet that it claims is prepared for a post-quantum world, saying it is taking aim at future threats to digital assets even as crypto crime surges today.

“We anticipate future risks by building our devices to be secure not only against today’s threats but also tomorrow’s,” Tomáš Susanka, Trezor’s chief technology officer, told Decrypt.

“A key example is quantum computing—a technology that could eventually break current cryptographic standards. With the Trezor Safe 7, we’ve introduced a quantum-ready architecture: Hardware that can support post-quantum cryptographic updates and a bootloader built on a hybrid classical and post-quantum signature scheme.”

Quantum computing is a developing technology that uses quantum mechanics principles to perform complex calculations far faster than traditional computers.

Unlike classical computers, which store data as ones or zeros, quantum computers use “qubits” that can represent multiple states at once through superposition and entanglement. This immense processing power could eventually break the cryptographic codes that secure cryptocurrencies by decrypting private keys.

“This means that when quantum-safe algorithms become necessary, Trezor devices will be ready to adapt — without compromising the principles of self-custody or forcing users to migrate their keys to a new device,” Susanka said. “We believe that long-term resilience starts with preparation, and that’s what we’re building for.”

Yet while that quantum future remains years away, today’s risks for crypto holders remain. Blockchain analytics firm Chainalysis reported that by the end of June 2025, $2.17 billion had already been stolen from cryptocurrency services.

The DPRK-linked $1.5 billion ByBit hack in February was the largest single theft in crypto history. And, if current trends continue, stolen funds from services could exceed $4 billion by year’s end. Personal wallet compromises now account for over 23% of stolen funds this year.

Susanka said the company has seen a shift in how users store their digital wealth.“While exchanges and custodial platforms were once the default, high-profile failures and rising awareness of security risks have driven more users toward self-custody,” he said.

Among the Safe 7’s new features is Trezor’s open-source Secure Element, the TROPIC01 chip. “For too long, the secure elements protecting our private keys have been opaque ‘black boxes,’ forcing us to simply trust the manufacturer. The TROPIC01 chip fixes this,” he said.

Still, not all threats are digital. So-called “wrench attacks” — physical assaults or kidnappings used to extract wallet access — are also on the rise. In recent months, France has seen a series of violent incidents, including the kidnapping of a crypto entrepreneur’s father who was tortured for ransom in Paris. In Singapore, a former military diver admitted to stealing $1.7 million after secretly photographing a seed phrase. TRM Labs estimates 70% of stolen crypto funds last year were taken through compromised private keys and seed phrases.

Susanka recommended five steps for users to keep their crypto safe. They are to use a hardware wallet, create a secure backup, verify transactions on the device, stay informed on best practices and only trust official support channels.

“With the right tools and habits, you can protect your crypto not just from digital threats — but from physical ones too,” he added.
