In November 2025, payment technology company Square officially launched its new Bitcoin payment feature, enabling roughly 4 million merchants on the Square platform to accept Bitcoin (BTC) at checkout. This rollout marks a pivotal step in the evolution of cryptocurrency from an “investment asset” to an “everyday payment tool.”

Square Debuts Bitcoin Payment Feature

According to Square’s official announcement, merchants can start accepting Bitcoin payments by simply enabling a setting in their Square dashboard. When a customer chooses “Bitcoin” at checkout, the merchant’s POS system generates a Lightning Network invoice or QR code, which the customer scans using a Lightning Network-enabled wallet to complete the transaction. During the promotional period, merchants pay no transaction processing fees, with an approximately 1% fee only kicking in after 2027.

Key Merchant Advantages: Instant Settlement and Zero Fees

This solution delivers several key benefits for merchants. The Lightning Network enables nearly instantaneous settlements, dramatically reducing the delay compared to traditional credit card payments. The zero-fee policy lowers the cost barrier for adopting Bitcoin payments, particularly appealing to small and medium-sized businesses. Merchants also have the flexibility to receive funds in Bitcoin or instantly convert to USD, which helps mitigate the risks of price volatility. Additionally, because Bitcoin transactions are irreversible and lack a chargeback mechanism, merchants face reduced fraud and refund risks.

Technical Foundation: Lightning Network and Settlement Paths

At the heart of Square’s Bitcoin payment capability is the Lightning Network—a layer-two protocol built on top of the Bitcoin blockchain that enables fast, low-cost settlements. The merchant generates a Lightning Network invoice, and the customer completes the payment using a compatible Bitcoin wallet, with immediate settlement. Square allows merchants to choose from multiple settlement paths: Bitcoin-to-Bitcoin (BTC→BTC), Bitcoin-to-USD (BTC→USD), USD-to-Bitcoin (USD→BTC), and USD-to-USD (USD→USD), giving merchants significant flexibility.

Impacts for Merchants and Consumers

Merchant perspective:

• Expanded payment options: Accepting Bitcoin opens access to consumers comfortable with cryptocurrency.
• Cost advantages: Traditional card network fees typically range from 1.5% to 4%, while Bitcoin payments incur zero fees during the promotional period.
• Potential long-term reserves: Merchants holding Bitcoin instead of converting immediately to fiat could benefit from price appreciation. Square also supports automatic daily conversion of a portion of card sales into Bitcoin.

Consumer perspective:

• Greater payment choices: Bitcoin holders can pay directly, expanding real-world use cases.
• Speed and convenience: Lightning Network payments complete in seconds, providing a major advantage for brick-and-mortar retailers.
• Potential incentives: Merchants adopting Bitcoin payments early may offer discounts or perks to attract users.

Risks and Future Outlook

While this launch is promising, both users and merchants should consider the following risks:

• Bitcoin price volatility: If merchants or consumers hold Bitcoin instead of converting immediately to fiat, they remain exposed to downside risk.
• Regional limitations: Some areas, such as New York State, currently do not support the feature.
• Adoption habits: While about 4 million merchants are covered, the actual number of Bitcoin payment users is still developing.
• Intensifying competition: Other payment platforms may introduce similar functionality, eroding Square’s differentiation.

Looking forward, as payment infrastructure improves and consumer education advances, Bitcoin’s adoption in brick-and-mortar commerce may continue to rise. Square’s initiative could become a major milestone in the mainstream adoption of cryptocurrency.
