X is teaming up with Visa to soon offer a system for real-time payments on the social media platform — signaling some progress in a yearslong vision from billionaire owner Elon Musk to create an “everything app.

Musk once dreamed of making X the “biggest financial institution in the world,” taking the first step of launching a peer-to-peer payments competitor to PayPal’s Venmo, Block’s Cash App and bank-owned Zelle.

Visa will be the first partner of the X Money account, under which customers can instantly fund their X wallet and connect their debit cards for peer-to-peer payments.
