Trezor One Recovery

Trusted Expertise in Trezor Model One Recovery

We specialize in recovering cryptocurrency wallets that others have written off as impossible. Among the most commonly encountered devices is the Trezor Model One. Despite its compact form and open-source ethos, it is built with strong defenses, and if a PIN is lost or forgotten, the wallet is effectively sealed shut.

That is, unless you call Praefortis.

We have developed methods to recover access to any version of the Trezor Model One; even without the PIN. Our recovery techniques are not theoretical or experimental. They are proven in the field, under pressure, and with real funds on the line. We have recovered millions of dollars for clients, including attorneys, fiduciaries, investors, and estate representatives. To date, we have never lost a customer wallet.

What Makes Trezor Model One Recovery Possible

The Trezor Model One protects access to private keys using a numeric PIN that is cryptographically entangled with the device's memory. After too many incorrect attempts, the device wipes itself clean. This makes traditional brute-force attacks useless.

However, the Trezor Model One lacks a secure element chip. This means that with precise timing, deep technical knowledge, and the right equipment, it is possible to glitch the microcontroller at just the right moment to bypass its protection mechanisms. This is not something a casual user can do. It requires skill, experience, and lab-grade tools.

Glitching a Trezor One: What It Takes

Our process begins with a physical teardown of the device. The Trezor’s case must be opened cleanly without damaging the board. Once open, we solder fine wire leads directly to test points on the PCB and prepare the device for power and data analysis.

We then connect the Trezor to a custom glitching rig (powered by an FPGA-based controller with sub-microsecond timing precision). We monitor power consumption and instruction flow using a high-bandwidth oscilloscope to isolate the boot sequence. Then we inject timed voltage glitches or EM pulses at precise execution intervals, often narrowed down to within 20 to 60 nanoseconds.

The goal is to momentarily disrupt the chip’s normal operation at a vulnerable point in the firmware logic, usually during PIN verification or memory loading. If successful, this opens a brief window to extract key memory contents such as the decrypted seed buffer or HMAC used in PIN verification.

This process can take dozens or even hundreds of attempts. Each glitch must be configured differently depending on the hardware revision, bootloader version, and chip characteristics. We have refined these parameters through years of testing and successful recoveries.

Safety and Precision Are Paramount

We understand that for our clients, this is a one-shot opportunity. Many of these devices contain funds that represent years of savings, inheritance, or the last remaining copy of a critical digital asset. That is why we have built a system where no action is taken blindly.

Our lab environment is tightly controlled and every recovery is logged. In all cases, we perform the extraction and verification on an imaged clone of the original flash memory to minimize any damage to the primary device. All sensitive data is encrypted and air-gapped from the moment it is accessed.

A Track Record You Can Rely On

Praefortis has earned its reputation by recovering wallets that others could not. Every case is handled directly by engineers with decades of experience working with hardware, encryption, and forensic recovery. Our clients range from individuals who lost access to their own wallets to law firms handling complex estates and international transfers of digital assets.

Even though every case carries some level of risk, to date we have never lost a customer wallet. That does not happen by chance. It happens because we take the work seriously, we invest in the right tools, and we never make promises we cannot keep.

When It Matters Most, We Are Ready

If you or your client has lost access to a Trezor Model One wallet, and the PIN is unknown or the device is malfunctioning, contact us. We will walk you through the recovery process, discuss potential outcomes, and treat your case with the same level of care and confidentiality that has made us a trusted name in the industry.

Our work is not easy. But it is worth it, because the assets inside your Trezor are worth protecting.
