Square Activates Bitcoin Payments for 4 Million U.S. Merchants
On March 30, 2026, Block's Square payments platform began automatically enabling Bitcoin payments for an estimated 4 million eligible U.S. sellers. This move transitions the feature from an opt-in tool, first introduced in late 2025, to a default setting, marking one of the most significant efforts to integrate cryptocurrency into mainstream retail.
Under the new system, merchants accept Bitcoin from customers, and the funds are instantly converted into U.S. dollars and settled. This process, which utilizes the Lightning Network for near-instant transactions, shields businesses from Bitcoin's price volatility and removes custody burdens. To further drive adoption, Square announced it will charge zero processing fees on these transactions through 2026.
Block's Strategy Aims for a Foundational Payments Standard
The automatic rollout is a core part of CEO Jack Dorsey's long-term vision to establish Bitcoin as "everyday money." By making Bitcoin acceptance the default, Square significantly lowers the barrier to entry for small businesses that have historically avoided crypto due to its complexity. This strategy positions Bitcoin as a pure payment rail rather than a speculative asset for merchants.
Industry leaders see the potential for a systemic shift. Lightspark CEO and former PayPal President David Marcus compared the initiative to a potential "TCP/IP moment" for money, referencing the foundational protocol that standardized data transfer on the internet. In this view, Bitcoin could become a universal standard for transferring value, allowing different financial systems to communicate seamlessly. The move puts Square's Bitcoin-first approach in direct contrast to competitors like PayPal, which are focusing on proprietary stablecoins such as PYUSD.
