Coinkite has been busy! Along with other features, they've developed payment processing very well since including BLK on June 1, 2014. They have Tor-enabled pay buttons, custom pay buttons, merchant price adjustment, nyms, automatic forwarding and integration with Shapeshift for instant conversions, too. All this is made available to merchants who accept BLK and use Coinkite for payment processing.
