May 27, 2026 — Block has quietly begun deploying USDC stablecoin payments inside Cash App, a source familiar with the matter told CoinDesk on Wednesday. The feature is now live for 25% of Cash App's nearly 60 million users, with full rollout expected by end of this week. A Block spokesperson confirmed the rollout.
The launch is the largest fintech deployment of stablecoin payment infrastructure to date and represents a stark reversal for Block CEO Jack Dorsey, a longtime Bitcoin maximalist. In March, Dorsey acknowledged the pivot plainly: "I don't like that we're going to support stablecoins but our customers want to use them."
The integration treats USDC strictly as a payment rail, not an investment product. Users can deposit USDC from external wallets to fund their Cash App fiat balance, or withdraw that balance as USDC to external wallets. The feature supports four networks: Solana, Ethereum, Polygon, and Arbitrum. Block's documentation warns that transactions are irreversible — funds sent to incorrect addresses or unsupported networks are permanently lost.
Access carries hard limits: $2,000 daily and $5,000 weekly for sending; $10,000 weekly for receiving. The feature is unavailable in New York and on sponsored accounts. Identity verification is required.
The rollout lands as the stablecoin market hits a record $322 billion in total value — surpassing the foreign exchange reserves of 95 countries, including the United Kingdom and Canada, according to CoinDesk's reporting from May 26.
For years, Dorsey anchored Block's crypto identity around Bitcoin exclusively, backing mining hardware and pushing BTC integrations across Cash App and Square. The USDC launch ends that single-asset posture, folding in Ethereum's ecosystem and three of its scaling layers.
Block first announced the feature on the Cash App website late last year, naming 2026 as the target. Wednesday's quiet deployment confirmed it.
Review note: The Dorsey quote used here is verbatim from the CoinDesk primary source: "I don't like that we're going to support stablecoins but our customers want to use them." The brief's version omits the second sentence. I used the confirmed primary text. All other figures — 60M users, 25% rollout, four networks, daily/weekly limits, $322B market cap — are sourced directly from the CoinDesk article (confirmed by Block spokesperson) and the stablecoin market cap piece linked in the brief. The Cash App help page was inaccessible for direct verification but the product details are confirmed in the CoinDesk article which cites that page explicitly.
