Block began rolling out USDC stablecoin payments to Cash App's nearly 60 million users on May 27, 2026, confirmed by a Block spokesperson to CoinDesk — a pivotal capitulation by a CEO who, just two months earlier, said he did not want to do it at all.
The launch is phased. As of Tuesday, the feature was live for 25% of users; full rollout is targeted by the end of the week, according to a source familiar with the matter who spoke to CoinDesk.
The feature is narrowly defined as a payment rail, not an investment product. Users can deposit Circle's USDC from external wallets to fund their fiat Cash App balance, or withdraw their balance as USDC to an external account. The supported networks are Solana, Ethereum, Polygon, and Arbitrum. Blockchain transactions are irreversible — funds sent to incorrect addresses or unsupported networks are permanently lost, per the product documentation.
Limits are tight: identity-verified users can send $2,000 per day and $5,000 per week, and receive up to $10,000 per week. The feature is unavailable in New York and on sponsored accounts.
The launch is notable as much for who authorized it as for what it does. Jack Dorsey built Block's crypto identity around Bitcoin alone — mining hardware, Lightning Network integrations, bitcoin balance on Cash App. In March 2026, facing the inevitable, he said plainly: "I don't like that we're going to support stablecoins but our customers want to use them." That quote has now become the mission statement of an active product.
Cash App had first announced stablecoin support in November 2024, framing it as a coming feature. It is live now.
The timing tracks with a broader market moment. The total stablecoin market capitalization hit a record $322 billion this week, surpassing the foreign exchange reserves of 95 countries, including the United Kingdom and Canada, according to CoinDesk data. Cash App's rollout adds one of the largest consumer distribution channels in the United States to that ecosystem in a single week.
Structurally, the move reframes stablecoins as plumbing rather than as an asset class — the same framing regulators have been pushing in Washington. The feature does not let users hold USDC as an investment; it uses USDC to move dollars cheaply across chains. That is exactly the use case the GENIUS Act, currently advancing in the Senate, is designed to govern. Block is shipping the product the regulation is being written for.
