[JadeLink](https://store.blockstream.com/products/jadelink-air-gapped-usb-drive) is a USB-C storage drive designed for pairing with [Jade Plus](https://store.blockstream.com/products/jade-plus) to perform air-gapped firmware upgrades and transaction signing. When using JadeLink in combination with the Jade Plus camera, you can perform all functionality possible with a Jade Plus in a completely air-gapped manner (including device unlock and receive [address](https://glossary.blockstream.com/address-bitcoin/) verification).

> **Note:** You can use most generic USB drives and SD cards formatted to FAT32 for this functionality. JadeLink is not specifically required.

## JadeLink Functionality

JadeLink currently supports the following functionality:

- **[Firmware Upgrades](https://helpcenter.dxp-frontend.devserver.app/blockstream-jade/use-jade-air-gapped/perform-an-air-gapped-firmware-upgrade):** Download Blockstream-signed firmware binary and hash files to upgrade your Jade Plus in seconds
