Button Wallet is built on Telegram messenger with principles of decentralization. Button focuses on optimizing usability and security for users looking to split the finances of shared experiences with friends. A good use case is friends sharing housing, ticket and dining expenses (like Coachella) within an existing group chat, like Telegram. Whether needs are compensating someone for a small freelance gig, tipping a barista, or sharing a meal with friends, Button users can send funds to their friends using only Telegram usernames.
