Beginning this Monday, Square has initiated the automatic activation of Bitcoin payment options for millions of qualifying small businesses across the United States, as per a recent update.
The company is utilizing the Bitcoin Lightning Network and will automatically convert all merchant transactions into U.S. dollars.
Importantly, Square is implementing Bitcoin acceptance without requiring any extra setup from merchants.
Miles Suter, who leads Block’s Bitcoin product division, confirmed this rollout on X. He emphasized that sellers opting to accept cryptocurrency will receive payments in fiat currency by default. “We’re simplifying the process for millions of businesses to adopt bitcoin,” Suter remarked. “This marks the beginning of bitcoin being used as everyday currency.”
Additionally, it should be noted that Square is eliminating all processing fees associated with these transactions until the end of 2026.
The extensive nature of this initiative is particularly significant; it aims at an eligible audience comprising approximately 4 million U.S. merchants—accounting for 78% of Square’s customer base.
Increased Adoption of Lightning
Square’s framework opts to bypass the primary Bitcoin blockchain in favor of leveraging the Lightning Network instead.
This network functions as a “Layer 2” protocol built directly atop the foundational blockchain layer.
The main Bitcoin blockchain only comes into play when a payment channel reaches its conclusion; at that moment, it logs the final net balance within its records.
By facilitating payments through Lightning technology, Square provides a checkout experience comparable in speed to traditional credit card systems while functioning on an open and decentralized monetary network.
David Marcus, CEO of Lightspark and former President at PayPal, referred to this integration as potentially representing a “TCP/IP moment” for global financial systems infrastructure.
