Block's Cash App to Roll Out USDC Transfers to About 15M U.S. Users

Cash App, Block's peer-to-peer payments service, is rolling out support for Circle's USDC stablecoin to roughly 15 million users this week. The launch reaches about a quarter of the app's customer base and enables users to send and receive a dollar-pegged digital currency, with any incoming USDC automatically converted into U.S. dollars inside the app. The new feature allows Cash App customers to transfer USDC, which is designed to track the U.S. dollar one-for-one. Recipients won't hold crypto in their balance: once USDC arrives, it is immediately converted to dollars in the user's Cash balance, removing exposure to price swings and eliminating the need to manage a separate wallet. Block announced the stablecoin capability on November 13, 2025. The company is building the USDC transfer rails on Solana, citing the network's speed and low fees as a fit for the smaller, more frequent payments common on Cash App. The initial rollout covers a meaningful portion of Cash App's audience. The platform reported about 47 million active users in 2022, while more recent commentary has put monthly active users around 57 million, placing this first wave at roughly one-quarter to one-third of the base depending on the benchmark. Cash App has long had exposure to crypto, offering Bitcoin trading for years and previously enabling Bitcoin payments via the Lightning Network, a layer-2 system aimed at cheaper, faster BTC transactions. Stablecoins address the volatility issue by design: USDC is meant to maintain a steady value tied to the dollar, making it suited to everyday transfers, payments for services, and cross-border remittances that can otherwise take days through traditional banking channels. For Circle, the integration is a distribution boost that puts USDC in front of a broader mainstream audience than crypto exchanges alone typically reach. It also bolsters USDC's positioning against Tether's USDT, which leads global stablecoin volume but has had less penetration in regulated U.S. consumer apps. For Solana, Block's decision to build on the network over alternatives such as Ethereum underscores confidence in Solana's transaction economics; sustained Cash App activity could add a high-profile payments use case to Solana's growing roster of real-world applications.
