Twitter has started applying for regulatory licenses in the U.S. for payment services on its platform.  According to sources, the social media company has also begun designing software that would allow various payment services on the platform, such as peer-to-peer transactions, savings accounts, and debit cards. CEO Elon Musk aims to diversify Twitter’s revenue stream and turn the social media platform into a “super app” that includes messaging, payments, and commerce. Prior to Musk’s takeover of the company, Twitter had set up a subsidiary called Twitter Payments LLC in August. Musk recently appointed Twitter’s director of product management, Esther Crawford, as the chief executive of Twitter Payments. Crawford and a small team have begun to map out the architecture needed to facilitate payments on the platform, including conceiving a vault for storing and protecting user data. Crawford joined Twitter in 2020 after the social media company acquired her startup, Squad. She led the development of various early products at Twitter, including Spaces and Communities.
