The Whoppercoin launched in tandem with a new loyalty program. For each Whopper burger customers purchase, they’ll receive one Whoppercoin in a special cryptocurrency wallet. While the coins’ wider use is unclear, some reports suggest that the Whoppercoin will be accepted as payment at Burger Kings across Russia.
Fortune asked Burger King for comment on the program and will update this story with any further information.

The introduction of the Whoppercoin on August 22 follows reports earlier this summer that Burger King Russia would be accepting bitcoin as payment. Burger King has reportedly issued one billion Whoppercoin tokens to date on Waves Platform, though it is possible that there will be more to come.
