“Twym is designed to facilitate instant transfers in rubles between Twitter users who have Yandex.Money accounts. To send money, users send a tweet that includes @twymru, the recipient’s username on Twitter, and the amount they want to transfer.
If the recipient has already activated Twym, they receive the rubles immediately. If not, they will be prompted to activate Twym and receive the money after they have done so. If someone retweets a money tweet, another transfer will be made from their Yandex.Money account to the same recipient – a useful feature for fundraising campaigns.”
