A few others and I have been testing multi-signature wallets with electrum the last days.
We've tested 2-of-2 and 2-of-3 wallets, and so far, everything worked like a charme.
Sending the partially signed transactions to each other via .txn file or the raw transaction hash was easy and worked quickly.
To me, electrum seems to be one of the best tools for multi-sig wallets right now.
However, the only thing we've not been abled to get to work is the Cosigner Pool plugin.
It's activated in the settings, but regardless of which version of electrum we use (I've tested it with 2.5.4 / 2.6 and 2.6.2),
once we try to send the partially signed transaction via the pool, either electrum crashes or we're getting the following error:
Failed to send transaction to cosigning pool.
Now our question would be, if this is a known (or general) error or if there is some error on our side, and some troubleshooting we can do.
Thanks for the help in advance.
After asking a few questions over at #electrum, we think the problem is, that the server we're connected to doesn't offer the cosigner pool service.
Is there a list of servers which do, or an easy way to check which servers support it?
