The interface must be polished, but it is not horribly bad.
My main feedback is that it is not clear how each of the details you ask will be used.
For example, when registering, you show a textarea prompting for my address -- why? It isn't clear. Maybe this should be asked later when it is actually needed. Also the phone and age.
When trying to submit or request a payment the form is very confusing. What do you mean by "Receiver Name"? Are you going to identify the person by her name? Phone number? What is this pickup number? Why did I click on "Send and Request" but only get a form to (supposedly) send? Everything is confusing.
The video on the landing page that should explain how everything works isn't live, but you should also have a clear explanation in words and images of how it works, besides the video.
The overall impression I have is that I'll pay with my credit card and tell you the name and phone number of someone in Nigeria, then someone will get the money in the US and keep it while someone else in Nigeria will start walking through the streets calling the recipient to try to give him money.
To me personally it would be great if it worked like this, but I would never write my credit card details or send lumens to a site so confusing.
