Square has rolled out Bitcoin payment support across its terminals in the U.S., allowing over four million merchants to accept BTC through the Lightning Network without needing new hardware. The integration makes it seamless for businesses to either retain the bitcoin they receive or instantly convert it into USD, creating a low-friction gateway to Bitcoin adoption in everyday commerce.

This move positions Square as a major player in Bitcoin payment infrastructure, bringing Lightning’s scalability and speed to real-world retail. The rollout, scheduled for full deployment by 2026, could mark a turning point in how digital currency is used in day-to-day transactions, particularly among small businesses looking to tap into a younger, tech-savvy customer base.
