The latest Electrum versions only generates Native SegWit electrum seed by default, that includes the format of the master keys.
For example, the master public key that you're getting starts with "
Zpub" intead of "
xpub".
There's a workaround to convert the Zpub key but there must be a way indicate that the HD MultiSig wallet that you'll create in Green/Bitpay is Native SegWit.
To convert the Zpub key, go to "
Console" tab (
View-Show Console), then type:
convert_xkey(xkey="ZprvAWgYBB.....wCND7HYcZr",xtype="standard")
Replace "
ZprvAWgYBB.....wCND7HYcZr" with your master public key.
However, Bitpay is using an exclusive "
Invitation Code" instead of xpub so it may not work.
Green on the other hand, doesn't have such option only their "
MultiSig Shield" or it's only available in the IOS version which I do not have.
