While I am contacting and building relationships with taxi companies supportive of cryptocurrencies, I have made no public announcements concerning any deals. When the time does come to make these announcements, you can be assured that they will be posted here and upon the Quicksilver Twitter

That being said, due to the nature of open source software, companies could accept Quicksilver as payment without telling me. Not saying that this is what happened, however as we roll out new infrastructure and branding for Quicksilver, it should become increasingly easy for the community to help ambassador this project.
