People often buy with
The flagship of the OneKey line, built for people holding meaningful value and moving it often. Its real differentiator is air-gapped signing: the built-in camera scans a QR from your phone or computer and returns the signature as another QR. The device never plugs in and never pairs. Even a fully compromised computer has no channel to reach your keys.
- Air-gap QR signing, plus USB-C, Bluetooth and NFC when you want convenience instead
- 4× EAL 6+ certified secure elements — the same standard as bank card chips
- 3.5” colour touchscreen, 480 × 800 — read the full destination address before you confirm
- Fingerprint unlock with PIN as the fallback layer
- 530mAh battery with Qi2 wireless charging
- 30,000+ coins across 100+ chains, with NFT and DeFi support; works with MetaMask, OKX and Rabby
- Fully open source on GitHub, independently audited by SlowMist
