We do not use any third party cryptocurrency payment processor. The transactions are made from wallet to wallet: from buyer to Market 4 Names and from Market 4 Names to seller.
We do operate this way to protect buyers and sellers from being scammed.
In case you don't receive the domain, you will get your money back. In case the buyer doesn't pay the domain, you still have it. Whether you are a buyer or seller, you have your transactions covered.
