When you set up swaps on Jade, the Blockstream app requests a child key from your Jade. This child key is a limited credential that lets the app recover your funds if a swap fails to complete. In normal swap operation, your funds remain fully controlled by Jade from start to finish; the child key is only used if a swap does not settle as expected.
What the Child Key Is Not
The child key is not your recovery phrase. It does not give the Blockstream app, or anyone who obtains it, the ability to:
- Derive or recover your recovery phrase
- Move funds held on your main wallet accounts
- Sign Jade transactions outside of a failed-swap refund
- Access funds once a swap has settled (settled funds remain fully controlled by Jade)
Your recovery phrase stays on Jade. Jade's unique security model ensures that there is nothing of value to steal from a locked Jade by itself.
Only Export When the Official Blockstream App Requests It
Warning: Only export a child key when prompted by the official Blockstream app. If any other app, website, or QR code asks Jade to export a child key, decline and disconnect. If a malicious actor obtains your child key, they can only claim funds from swaps that fail to settle; completed swaps remain fully controlled by Jade.
Download the Blockstream app only from blockstream.com/app, the Apple App Store, or Google Play. Verify the publisher is "Blockstream Corp Inc." before connecting Jade.
