Verdict
Score 4.3/5, very strong profile. In its favour: fully open-source firmware and apps with reproducible builds and audits (SlowMist); affordable range from ≈€79; EAL 6+ secure element; the Pro offers air-gapped QR signing. The trade-off to weigh: the secure element chip is third-party (closed-source by nature, like all certified SEs); the Classic models use USB-C/Bluetooth, not air-gapped; less established brand than Ledger/Trezor.
On the Sovereignty lens the score is 4.8/5 (outstanding): the strength is fund control (5.0/5), while privacy & anonymity (4.5/5) is the weak link.

FAQ
How much does a OneKey cost?
The entry-level Classic 1S Pure costs about €79 ($79 on the official shop). The Bluetooth Classic 1S about €89, and the flagship Pro, with touchscreen and air-gapped QR signing, about €285 at European resellers.
Is OneKey really open source?
Yes: firmware and apps (desktop, mobile, browser extension) are published on GitHub with reproducible builds, so anyone can verify the installed binary matches the code. The only non-open component is the third-party secure element chip, which is closed-source by nature, as in every hardware wallet with a certified SE.
Is the OneKey Pro air-gapped?
The Pro supports QR-code transaction signing via its built-in camera, so it can operate air-gapped. The Classic 1S models connect via USB-C or Bluetooth instead.
