If you only hold Bitcoin, that focus is a feature: less code means fewer places for something to go wrong, and the firmware is built by people who work on Bitcoin infrastructure full time.\u003c\/p\u003e\n\u003ch3\u003eHow Jade secures your keys\u003c\/h3\u003e\n\u003cp\u003eJade uses what Blockstream call a \u003cb\u003eVirtual Secure Element\u003c\/b\u003e, built on blind oracle encryption. It allows the device to remain fully open source while resisting physical key extraction — Blockstream describe it as simulating the protection of a secure element in software rather than a dedicated chip.\u003c\/p\u003e\n\u003cp\u003eThat is a deliberate design choice: secure element chips are proprietary and cannot be fully audited, so Blockstream chose transparency instead. It is a different security philosophy, not a weaker one — and it is the reason Jade can claim to be fully open source.\u003c\/p\u003e\n\n\u003ch3\u003eSecurity features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e100% open source firmware and hardware, fully reviewable\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAir-gapped QR signing\u003c\/b\u003e — scan and display QR codes directly on Jade, with no USB or Bluetooth connection required\u003c\/li\u003e\n\u003cli\u003eAir-gapped firmware upgrades\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAnti-Exfil signatures\u003c\/b\u003e, which prevent a compromised device from leaking your key through the signatures it produces\u003c\/li\u003e\n\u003cli\u003eGenuine device check\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDice-roll entropy\u003c\/b\u003e — add your own physical randomness when generating your recovery phrase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eColor display with a camera for QR scanning\u003c\/li\u003e\n\u003cli\u003eUSB-C and Bluetooth\u003c\/li\u003e\n\u003cli\u003e60 x 24 x 17 mm, 21 g\u003c\/li\u003e\n\u003cli\u003e240 mAh battery\u003c\/li\u003e\n\u003cli\u003ePlastic body\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBackup and compatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12 or 24-word recovery phrase, or recovery by QR scan\u003c\/li\u003e\n\u003cli\u003eBlockstream app: Android over Bluetooth or USB-C, iOS over Bluetooth, desktop over USB-C\u003c\/li\u003e\n\u003cli\u003eAlso works with BlueWallet, Electrum, Nunchuk, Sparrow, Specter and HWI\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlockstream Jade hardware wallet\u003c\/li\u003e\n\u003cli\u003eUSB-C to USB-C cable\u003c\/li\u003e\n\u003cli\u003e3 recovery sheets\u003c\/li\u003e\n\u003cli\u003eGetting started leaflet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eDoes it have a secure element?\u003c\/b\u003e\u003cbr\u003eNot a dedicated chip.
