Based on the explanation on this page[1], the buyer needs to trust that you don't run away with their money to use this service. I don't see a multi-sig or similar option where the buyer or seller can participate in releasing the escrow at all, so they have to rely on your service from beginning to end. I don't think that's really attractive, especially with how new you are. How would you solve this issue?
