Square Enables Bitcoin Payments for 4 Million US Small Businesses with Instant Dollar Conversion

Square, the payments subsidiary of Block, began automatically enabling Bitcoin payments for eligible US small businesses on March 31, 2026, shifting from an opt-in to an opt-out model that integrates cryptocurrency acceptance directly into existing payment systems for approximately 4 million merchants.

The feature converts Bitcoin transactions to US dollars instantly at checkout with near-instant settlement and zero processing fees through 2026, removing merchant exposure to Bitcoin price volatility and eliminating custody requirements.

Square’s Automatic Enablement Model Removes Volatility and Custody Barriers for Merchants

Square’s new Bitcoin payment feature is automatically enabled for eligible US sellers, with transactions converted to US dollars by default at the point of sale. The approach addresses two primary barriers that have historically prevented small businesses from accepting cryptocurrency: price volatility and the operational complexity of holding digital assets.

Merchants who accept Bitcoin payments receive US dollars as their default settlement currency, with the conversion handled automatically in the background. Block’s head of Bitcoin product, Miles Suter, stated that the ability will roll out to all sellers in the coming month. The feature builds on Square’s broader Bitcoin initiative but represents a significant shift, as Bitcoin acceptance is now integrated directly into existing payment systems rather than requiring merchants to activate it separately.

The automatic enablement model stands in contrast to the previous approach where Square users had to optionally enable the feature. Merchants retain control and can opt out or adjust settings if they prefer not to accept Bitcoin payments. The feature carries zero processing fees for Bitcoin transactions through 2026, according to the company.

Industry Leaders Compare Integration to TCP/IP Standardization for Financial Infrastructure

Lightspark CEO and former PayPal President David Marcus described the rollout as a potential “TCP/IP moment” for money, comparing the move to the early standardization of internet protocols that enabled disparate networks to communicate through a shared standard. Marcus suggested Bitcoin could play a similar role in financial infrastructure by creating a common framework for moving value between users and platforms.

Suter characterized Bitcoin as everyday money as a long-term journey for Block, noting that many moves remain to make the integration sustainable. Block CEO Jack Dorsey confirmed the rollout with a succinct post on X. Dorsey, a Bitcoin advocate, has previously expressed reservations about stablecoins but recently indicated the company would support USD-pegged tokens due to increasing customer demand.

The integration could significantly expand Bitcoin’s real-world payment footprint. Rather than targeting crypto-native users, Square is embedding Bitcoin payment tools into systems already used by millions of small businesses for payments, inventory, and payroll. Square’s user base is 78% US-based and 22% international, according to recent investor presentations.

PayPal Stablecoin Expansion and Block’s Broader Bitcoin Ecosystem

The Square Bitcoin payments rollout coincides with PayPal’s recent expansion of its US dollar-backed stablecoin, PYUSD, to tens of thousands of users across 70 markets worldwide. Both moves reflect payment processors’ efforts to deepen digital payment capabilities, though they pursue different technical approaches—PayPal through stablecoins and Square through Bitcoin with automatic conversion.

Beyond Square payments terminals, Block has pursued multiple Bitcoin initiatives including buying and selling Bitcoin through Cash App, launching a Bitcoin hardware wallet, and developing a modular Bitcoin mining system. Cash App has added stablecoin support despite Dorsey’s personal Bitcoin maximalist stance, a move the CEO acknowledged was driven by customer demand.

Block recently reduced its workforce by approximately 4,000 employees, representing about 40% of its staff, as part of an efficiency initiative that included increased focus on artificial intelligence tools. Block’s stock (XYZ) traded at $56.76 on the day of the announcement, up more than 1% but down approximately 11% over the preceding month.
