Cash App Rolls Out USDC Stablecoin Support Across Four Major Blockchains

Table of Contents Block, Inc.’s flagship mobile payment platform Cash App has introduced support for USDC stablecoin transactions spanning four distinct blockchain networks. This development marks one of the most substantial cryptocurrency expansions the service has undertaken since integrating Bitcoin functionality several years ago. Stablecoins are here on Cash App. Send and receive USDC that auto-converts to USD, fee-free to start. No wallet setup. No extra app. Just Cash App. pic.twitter.com/KyOFb1ZM9h — Cash App (@CashApp) May 27, 2026 Miles Suter, who leads Bitcoin product development at Block, verified the launch through social media channels. The platform now enables users to both send and receive Circle’s USDC stablecoin across Solana, Ethereum, Polygon, and Arbitrum networks. Block has waived all transaction fees for these transfers. According to Suter, the entire process operates directly from users’ standard dollar balances. There’s no requirement to maintain a dedicated cryptocurrency wallet or navigate across different blockchain networks. When USDC arrives in a Cash App account, the platform automatically converts it to U.S. dollars. Users see this reflected as a conventional dollar balance rather than a distinct cryptocurrency asset. This approach differs from competing services. PayPal’s Venmo platform, by contrast, displays its PYUSD stablecoin as a separate entry within its cryptocurrency section. The functionality remains unavailable to New York state residents currently. Additionally, users must complete identity verification procedures before accessing the feature, and transfer limits are enforced. Jack Dorsey ranks among the technology industry’s most vocal Bitcoin advocates. Block has dedicated years to developing Bitcoin-centric products — including its Bitkey self-custody wallet solution, the Proto mining hardware, and the Spiral open-source development initiative. Dorsey has previously expressed skepticism toward stablecoins, characterizing them as simply shifting dependency “from one gatekeeper to another.” He articulated this viewpoint earlier in the current year. However, user demand seemingly prompted the company to reconsider its position. At launch, Suter characterized stablecoins as a “complementary option,” emphasizing that Cash App’s primary commitment remains with Bitcoin. Suter articulated the company’s framework clearly this week: Bitcoin represents “Money 2.0,” traditional fiat represents “Money 1.0,” and stablecoins function as the connecting infrastructure between these two systems. Block isn’t operating in isolation regarding stablecoin adoption. Visa, Mastercard, and numerous other payment processors have been expanding their stablecoin initiatives. The aggregate stablecoin market capitalization recently surpassed $300 billion. Cash App reports a user base of 59 million monthly active accounts. This past March, Block’s Square division also activated Bitcoin payment acceptance as a default setting for U.S. merchants, replacing the previous opt-in configuration. This change enabled businesses to automatically convert credit card transactions into Bitcoin. Block’s stock was trading near $71.55 Wednesday afternoon, representing an increase of nearly 3.5% for the session. Year-to-date, the equity has appreciated approximately 10%. As of the end of the first quarter, Block maintained 9,032 Bitcoin on its corporate balance sheet, representing approximately $675 million in value. This position establishes the company as the 14th largest publicly traded corporate Bitcoin holder worldwide.
