Square to enable bitcoin lightning payments as default for over 4 million merchants ⚡️ Square will auto-enable #Bitcoin payments for all eligible partners starting March 30, 2026. A Terms of Service notice was sent to merchants registered with Square's POS solutions. This means over four million businesses using Square could become Bitcoin accepting merchants overnight. Up until now, business owners had to manually activate bitcoin payments and decide whether to auto-convert to USD or keep in BTC. The rollout is part of Block’s push to integrate #Bitcoin payments across its ecosystem including CashApp, leveraging the Lightning Network instant, low-cost transactions. Sellers will still have the option to disable the feature or automatically convert #Bitcoin to USD at the point of sale.
