Research direction
No files, tests, or entry points are named. Start by reviewing Jade's existing PSBT, QR-code, and multisig capabilities; done would require a confirmed feasibility and scope decision for coordinator-free 2-of-3 creation and signing.
Written by the indexing model from the issue text.
Description
With the Jade Plus’s upgraded chip, is it possible to add support for creating and managing a 2-of-3 multisig wallet directly on Jade devices using QR codes, without a PC or mobile coordinator?
This would involve:
- Exchanging public keys via QR codes to generate a 2-of-3 multisig script.
- Signing PSBTs by scanning and passing QR codes between devices.
Rationale:
• Avoids potential malware risks from coordinators (PC/mobile).
• Leverages Jade’s air-gapped QR code functionality for a secure, offline workflow.
Given Jade’s PSBT support and the Jade Plus’s enhanced hardware, is this feature feasible for a future firmware update?
