This also raises another question, Why does the jade has its own export button, is it not using the standards? But I see a lot of different export buttons in the Sparrow wallet. Why are there so many export, is there no standard?
So, my main question is, is it possible to do what I want or does the Specter Destop wallet not support a Jade export?
I'm not so familiar with Specter and I don't get what you are pointing to since you talk about multisig wallet why are you looking for jade export on Specter it's not available like on Sparrow.
Sparrow just support multiple wallets that is why they have many option under export.
About the main question since this is all about multisig then there's no option to use jade export on specter the option to export wallet from specter is through PDF or .json file its far from Sparrow wallet that supports most software wallet and hardware wallets while Jade is a hardware wallet, a separate wallet and use only for signing.
