The "Built on Ripple" badge is simply a representation of the below paragraph*. We are not however, "Ripple" and we are not officially sponsored or endorsed by Ripple Labs. Although, we wouldn't say no.
*Casheer utilizes Ripple's near instant payment network and distributed exchange, to facilitate low-cost, cross-currency transactions through the Casheer platform. Now bitcoins for example, can be sent to a merchant who doesn't accept Bitcoin payments directly. The Ripple network does the currency exchange near-instantly and delivers say, USD to the merchant.
Everyone wins...especially the blockchain because BTC payments are now moving off-blockchain and reduces the need for block size increases to deal with TPS limits.
I speak for about 2 out of the 3 INCA crew when saying we would not mind if you added IncaKoin to this payment platform. You are welcome to use INCAKOIN on this platform if you were so inclined to do so.
