Jade signs transactions by exchanging QR codes with the Blockstream app through its camera. The private keys never leave the device, and no USB data connection is needed to approve a transaction.
Both the hardware design and the firmware are open source and published on GitHub. Anyone can read the code, audit it, or build the firmware from source.
Bitcoin and the Liquid Network, including Liquid assets. Jade is built for Bitcoin and its sidechains, with no altcoin support.
Your recovery phrase is encrypted on the device and unlocked with your PIN plus a Blind Oracle, a server that never sees your PIN or your funds. After three wrong attempts it permanently destroys its half of the key. There is no closed chip, and the whole model is open source and verifiable.
Setup is guided through the Blockstream app and takes a few minutes. The security model runs in the background while you confirm transactions on the device.
