I have a site which generates multisig addresses given the right public keys, and asks users to sign locally on their computer/client. So far I've only gotten it working with Bitcoind. Would anyone here be willing to test out a 2of2 transaction, where you input a public key from your electrum MPK?
The site asks you to enter a transaction ID for your payment to the multisig address, and to enter an address to send the funds back to. I've tried it with electrum, but been unsuccessful with it. It appears it doesn't recognize the transaction, because it doesn't have all the keys in the wallet.. But the functionality seems there, so I'm sure it can be done by someone who knows electrum/python a bit better.
