Square began auto-enabling bitcoin payments for eligible U.S. sellers

Square began a phased rollout on March 30, 2026 that automatically enabled bitcoin payments for eligible U.S. sellers, moving the option from something merchants had to activate toward a default payment method inside its point-of-sale system.

The operational choice was conservative even as the distribution change was ambitious. A customer could pay bitcoin over the Lightning Network, while the seller received U.S. dollars by default. Sellers could change settlement to bitcoin or disable the payment option. Square said the rollout would proceed over the following month rather than reach every eligible account at once.

That made March 30 less a claim that bitcoin had become ordinary money than a large test of whether removing setup friction could change merchant acceptance. Availability at checkout is not the same as customer demand, completed payment volume or merchant willingness to keep the feature enabled.

What Square changed

Square had announced its integrated bitcoin payments and wallet product in October 2025 and said bitcoin payments would become available on November 10, 2025. That initial product let eligible sellers choose to accept bitcoin through Square hardware and settle proceeds either in bitcoin or local currency.

The March 30 change reversed the activation burden. Square’s support material specified that sellers were auto-enabled and that dollar settlement was the default. Contemporaneous reporting attributed the phased point-of-sale rollout to Miles Suter, Block’s bitcoin product lead. The company limited availability to eligible U.S. businesses outside New York, subject to business-verification requirements.

At checkout, Square’s published flow generated a Lightning invoice as a QR code for the buyer to scan with Cash App or another Lightning-enabled wallet. The payment then appeared in the seller’s Square Dashboard in dollars or bitcoin, depending on the settlement setting. Square advertised a zero processing fee through December 31, 2026; its support page said a 1% fee would apply afterward.

Those terms did not eliminate every economic or operational difference from card acceptance. Bitcoin payments did not carry the card-network chargeback process, and a merchant choosing bitcoin settlement assumed exposure to changes in bitcoin’s dollar value. Default dollar conversion was designed to keep that price exposure away from sellers that only wanted another checkout method.

Distribution was the consequential part

Block’s Form 10-K for the year ended December 31, 2025 said more than 4.5 million sellers used the Square ecosystem, recording 5.9 billion sales transactions and $250 billion of Square gross payment volume. Square defined that measure as the dollar amount of card and bank payments processed for sellers, net of refunds.

Those figures describe the worldwide Square ecosystem during 2025; they do not count merchants eligible for the March 30 U.S. bitcoin rollout, and the $250 billion was not bitcoin volume. They establish why a default setting at Square mattered institutionally: a bitcoin payment rail was being inserted into an established merchant platform rather than offered only through a crypto-native processor.

The change also separated payment acceptance from treasury adoption. A seller could receive dollars and never hold bitcoin. Conversely, Square’s wallet and conversion tools let an eligible seller retain bitcoin or convert a portion of other sales, but those were distinct choices. Counting every auto-enabled location as a bitcoin-holding business would therefore be wrong.

What remained unknown on March 30

Neither Square’s event-day announcement nor the contemporaneous report supplied completed bitcoin payment volume, the number of locations activated during the first day, the opt-out rate or the share of sellers choosing bitcoin settlement. No supported inference could be made about bitcoin’s price from the rollout.

The verifiable development was distribution: Square started making Lightning-based bitcoin acceptance a default capability for eligible U.S. sellers, with dollar settlement and merchant control preserved. Whether that capability produced sustained commercial use required later transaction data that was not available on March 30.
