Just getting around to diving into multisig and want to use it for a purchase on blankbank. However I have no idea how to obtain both the vendor/market public keys. I don't see it on the vendors profile where I would expect to see it with thier PGP key. It's also not listed when I go to purchase the item.
So whats the simple thing I'm missing?
When you click on buy(multisig) it pops up with a box to enter your public key and a btc address for returns. You don't need the vendor or markets public key because the market is making the multisig transaction, if you were making the transaction through electrum you would need this. After the order is made you will be able to see the vendors public key.
