Square expects to complete a phased rollout of Bitcoin payments across its network of more than 4 million merchants on November 10. According to Odaily, Bitcoin News said on X that the deployment began March 30 and automatically enables eligible U.S. merchants to accept Bitcoin without applying. Customers can pay through the Lightning Network, with transactions settling within seconds. Merchants receive dollars by default but can choose to retain Bitcoin. Square will waive Bitcoin payment processing fees through December 31, 2026, then charge a flat 1% fee. Merchants can also automatically convert up to 50% of daily sales into Bitcoin.
