No custody of funds
We recover key material and deliver it to you. We never move, hold, convert, or transmit assets.

What this is
Bench work, not account recovery.
ByteBack recovers key material from hardware you lawfully own. The work can involve faulting a microcontroller during boot, bypassing read-out protection, extracting firmware or memory, and reconstructing the material you need to regain access.
We have performed this work on Trezor One and Model T. Most devices and failure modes are not recoverable. You will get a direct feasibility assessment before an attempt begins.
The process
How a recovery starts.
Recovery starts by proving the device is yours and determining whether the hardware, firmware, and failure mode present a viable path.
- 01
Describe the device
Model, firmware if known, condition, what you remember, and how you came to own it.
- 02
Verify ownership
Identity, provenance, transaction history or addresses, prior knowledge, and a signed attestation.
- 03
Assess feasibility
We determine whether recovery appears possible and explain the chance of damaging the device.
- 04
Agree scope and custody
Commercial terms, chain of custody, shipping, and the exact technical objective go in writing.
- 05
Recover and deliver
Key material is delivered to you. ByteBack does not move, hold, convert, or transmit assets.
Non-negotiable operating rules
Conditions for taking a case.
Ownership first
Government ID, device provenance, prior knowledge, and a signed ownership attestation come before bench work.
No exchange accounts
We work on hardware wallets and encrypted key material—not login recovery or exchange accounts.
No disputes
No contested devices, undocumented estates, third-party claims, or devices the claimant cannot explain possessing.
Destruction is possible
Fault injection can brick a device. You acknowledge the risk in writing before an attempt.
Documented custody
The device is photographed on arrival, work is logged, and shipping is insured in both directions.
Start with the facts
Describe the device and how you came to own it.
Include the model, physical condition, firmware if known, and what changed immediately before access was lost. Do not send a seed phrase, PIN, passphrase, or private key in your first message.
