Square, a payment platform owned by Block, Inc., has started automatically enabling Bitcoin payments for eligible merchants in the United States. The rollout began on March 30, 2026, and is expected to be fully completed by November 10, 2026. The service utilizes the Lightning Network for transaction processing.
Merchants can accept payments without additional hardware, as the feature integrates directly into existing tools like Square Register and Invoices. By default, the system converts incoming Bitcoin into US dollars at the time of payment, though sellers have the option to retain the cryptocurrency. Additionally, businesses can convert up to 50% of their daily card sales into Bitcoin.
The fee structure for the service is set at 0% until December 31, 2026. Starting January 1, 2027, a flat 1% processing fee will apply. The service imposes transaction limits of approximately $600 per payment and a daily ceiling of about $20,000 per merchant. Availability is restricted in certain jurisdictions, including New York.
The initiative is led by Block CEO Jack Dorsey and Bitcoin product head Miles Suter. The company aims to simplify Bitcoin adoption for small businesses by removing the need for manual setup and mitigating volatility through automatic currency conversion.
