This is an interesting service and could be very helpful to any determined new/old project, i have few questions about erc20 gateway despite my likeness for your service.
1, Can this be integrated into any eCommerce marketplace.
2, Will the funds be available in the users balance when used as a deposit option and the user can use it to buy any goods/services offered by the eCommerce ?
1) Yes it can, we are currently working on the popular payment plugins for easy integration. But our API service is already live (BETA)
