Initially, we will not be charging a fee for quite some time, but later on, we will start charging a modest fee, something like 0.1%. It really depends on the community and we can assure you that we will keep all of our charges the lowest possible. The Team may decide to not charge any fees at all

We are currently exploring 2-of-3 multisig option to offer protection to buyer such that he/she will only transmit funds after receiving merchandise in a satisfactory condition.
And what fees will be paid by the merchant to use your platform as a payment processor for your web commerce? Will there be purchase protection in relation to the buyer, that is, buy and receive, because if don't receive,the protection for the refund?
