JadeLink is a USB-C storage drive designed to be paired with Jade Plus to perform air-gapped firmware upgrades and transaction signing. When JadeLink is used in combination with Jade's camera, users can perform all functionality possible with a Jade Plus in a completely air-gapped manner (including device unlock and receive address verification).
Note: Most generic USB drives and SD cards formatted to FAT32 can also be used for this functionality, JadeLink is not specifically required.
