Hi,
when I create multisig wallet with Electrum it generate a xpub key.
Xpub key is different from public key (starting with 02, 03, 04, etc.). How can I get the public key (starting with 02, 03, 04, etc.)?

I'm talking of public keys like in coinb.in site.
How can I generate a public key or multisig address with Electrum to use after in coinb.in site?
Thank you very much
