Can someone please help me with getting my Public Key from Multibit client? I heard you need your Public Key for multsig and I have no idea what that even is but I'm wondering how I can get the public key.
Isn't your public key the BTC address? I think you mean you're trying to get the private key. Go to the wallets menu and then to export private key. Then after you exported it to a file just open that file with notepad and you should see your private key in there.
