Ok figured it out the mint I selected didn't have dollar support so I changed it and transferred from @strike
Im still digesting how amazing this is, the federal reserve dollar is in strikes bank account, then I transfer the claim on that FR dollar to strike in exchange for a piece of data (ecash). At anytime I can return that to strike with proof that I gave them control of my dollars previously and then claim them back.
The transfer to the mint is over lighting correct? Strike takes the "dollar" on my app and converts it to bitcoin to send to mint?
