OneKey Pro vs Keystone 3 Pro: Connected Open Source vs QR Air Gap
Both flagships ship open firmware and large touchscreens — OneKey adds Bluetooth and reproducible builds; Keystone doubles down on QR air gaps and fingerprint security.
Choose OneKey Pro if you want reproducible open-source firmware plus Bluetooth mobile convenience, with QR air gaps when you want them.
Choose Keystone 3 Pro if you want to stay air-gapped by default with QR signing and fingerprint unlock, accepting slower mobile loops for isolation.
