It is still unclear to me:
Can I use a wallet that starts with a 3? It was generated by Electrum.
This is a multisig address, correct?
I can't see why you couldn't mine to it, but it seems a bit of extra effort for a pool payout. I don't run Eligius, so don't take this as a definitive answer. I never tried to mine to a multisig address
I am not sure if it is a multisig wallet.. I am not entirely sure what that means haha. But from what i've googled, I don't think it is a multi signature wallet...
