OneKey hardware wallets use multi-layered security mechanisms to protect your assets. Before you start using your device, you can confirm whether it is in normal condition by checking the packaging and device status, and running Genuine Check in the OneKey App.

​

For advanced users or technicians who need to further inspect the internal hardware of the device, this article also provides internal structure reference diagrams for OneKey hardware wallets to help identify obvious physical tampering or abnormal hardware.

Important Notice

OneKey hardware wallets are not designed for routine disassembly. Any internal hardware inspection should be performed by qualified technicians.

We strongly advise against disassembly by regular users. Disassembling the device may cause irreversible visible damage to the casing, screen, ribbon cables, sealing structures, or other components, and may make the device difficult or impossible to reassemble and void the warranty.

If you simply want to confirm whether the device is an authentic OneKey product, disassembly is usually unnecessary. Please prioritize checking the packaging, tamper-evident seals, initial boot state of the device, and running the Genuine Check feature in the OneKey App.

These two checks focus on different aspects.

With the Genuine Check feature provided by the OneKey App, you can confirm whether the connected hardware wallet passes OneKey's device verification. For the vast majority of users, this is the essential step to check the authenticity of a OneKey device.

This section is for reference only by advanced users, security researchers, and qualified technicians.

Under normal circumstances, you do not need to open your OneKey hardware wallet to verify whether it is safe to use.

If an internal inspection is genuinely required due to security audits, suspicious device provenance, or other professional reasons, you can compare the internal structure of the device with the reference diagrams below.

The structural reference diagrams are AI-rendered to help you better understand the device's composition—for accuracy, expand below to view the unrendered original photos of the exploded parts and the main PCB board.

​The appearance, silkscreen markings, suppliers, or PCB details of internal components may vary with regular hardware revisions and production batches.

Therefore, do not judge whether a device has been tampered with solely based on the color, silkscreen, or subtle cosmetic differences of individual components.

Disassembling the device yourself does not mean the Seed Phrase will be compromised immediately, but disassembly may:

Therefore, you should not disassemble a OneKey hardware wallet for routine authenticity verification.

For regular users, we recommend the following workflow:

Verify purchase channel → Check packaging and tamper-evident seals → Check first-boot status → Run Genuine Check using the OneKey App

Further inspection of internal hardware is only recommended if there are clear concerns regarding physical tampering and it is performed by qualified personnel.

Please note: Some OneKey products may undergo manufacturing improvements, material adjustments, and component tolerance changes after release. As a result, the weight of individual devices may vary slightly between production batches. Device weight should not be used as the sole criterion for verifying the authenticity or integrity of a device and should only be treated as a reference. For example, due to manufacturing improvements over time, the actual weight of some OneKey Classic 1S devices may differ from the listed reference weight by approximately 2–3 g.
