Feasibility of Coordinator-Free 2-of-3 Multisig Setup Using QR Codes on Jade Plus

[PeterMcBTC]

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:

1. Exchanging public keys via QR codes to generate a 2-of-3 multisig script.
2. 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?

Thanks for your input!

Not sure if Jade could scan a QR off another Jade (too small QR probably) but wonder if something could be done with JadeLink...
