No. CDNX is a platform for our dealer members to buy, sell, post bids and send broadcast messages. We simply facilitiate.

A member may post bids and asks on the CDN Exchange market. Other members may sell or buy from these members by executing against the posted bids or asks. Such a transaction would fall under CDNX Terms and conditions. CDNX members may also transact by any other means, such as over the telephone or at coins shows. These transactions would not fall under CDNX terms and conditions.

A single CDNX membership starts at only $100 per month. We offer add-ons like integrated CDN price guide values, dealer software and addition licenses for multiple users in the same company for a reasonable additional fee.
