Cash App, the peer-to-peer payments platform owned by Jack Dorsey’s Block, is rolling out USDC stablecoin support to roughly 15 million users this week. That’s about a quarter of its user base getting access to send and receive a dollar-pegged digital currency, with balances automatically converting to US dollars inside the app.
What the USDC integration actually does
The feature lets Cash App users send and receive USDC, the stablecoin issued by Circle that’s pegged one-to-one to the US dollar. When someone receives USDC, the app instantly converts it into dollars in their Cash balance. No holding crypto, no price volatility, no wallet management.
Block announced the stablecoin feature set on November 13, 2025. The company is building the USDC transfer capability on Solana, a blockchain known for fast transaction speeds and low fees. That’s a deliberate infrastructure choice, one that prioritizes cost efficiency for the kind of small, frequent payments Cash App users tend to make.
The rollout targeting 15 million users represents a substantial chunk of Cash App’s total audience. The platform had roughly 47 million active users as of 2022, with more recent commentary citing around 57 million monthly active users. So this initial wave covers somewhere between a quarter and a third of the platform’s base, depending on which user count you reference.
