From Announcement to Live Square Bitcoin Payments
On May 27, 2025, Block, Inc., previously known as Square, announced at the Bitcoin 2025 conference in Las Vegas that it would integrate Bitcoin payments via the Lightning Network into its point-of-sale (POS) terminals. The rollout is now live for eligible U.S. Square sellers outside New York. Merchants can accept Bitcoin through Square’s supported checkout flow, with the option to keep the cryptocurrency or have Square convert it to U.S. dollars.
This bold move empowers millions of merchants to accept Bitcoin directly through existing Square hardware, with the option to keep the cryptocurrency or instantly convert it to fiat currency. The rollout kicks off in the second half of 2025, with plans to reach all eligible Square sellers by 2026, pending regulatory approval. This blog dives into Square’s latest venture, traces Block’s Bitcoin journey, explores industry ripples, captures X community excitement, and spotlights how Aurpay fuels the crypto payment wave.
Block’s Bitcoin Odyssey: A Trailblazing Tale
Block, Inc. has long championed Bitcoin. Back in October 2020, the company, then Square, invested $50 million to acquire roughly 4,709 bitcoins, followed by a $170 million purchase of 3,318 bitcoins in February 2021. These moves underscored a belief in Bitcoin as a transformative global currency.
By 2018, Square rolled out Bitcoin trading on its Cash App, letting users buy, sell, and hold the cryptocurrency. In 2019, Square Crypto was born to boost open-source Bitcoin development, and in 2020, the Cryptocurrency Open Patent Alliance (COPA) launched to drive crypto innovation.
The 2021 rebrand to Block, Inc. cemented a broader blockchain focus. The 2024 debut of Bitcoin Conversions allowed merchants to turn daily sales into Bitcoin. Now, the Lightning Network integration takes this vision to the next level.
Inside Square’s Lightning Leap
Square’s new feature lets merchants accept Bitcoin payments through the Lightning Network, a second-layer solution that slashes costs and speeds up transactions. Customers simply scan a QR code at checkout, and the payment zips through almost instantly, with fees far lower than traditional on-chain Bitcoin transfers. Merchants can choose to hold Bitcoin or have it auto-converted to fiat in real-time, dodging volatility worries.
Current fees, limits, settlement, and refunds
Square’s current merchant support guide sets a $600 maximum for an individual POS Bitcoin payment and a $20,000 total daily POS limit. Processing is 0% through December 31, 2026, then 1%. Sellers can settle in Bitcoin or U.S. dollars. Square says POS Bitcoin transactions do not support chargebacks and refunds are issued as Square gift cards for the equivalent dollar amount.
Square Invoices use separate terms. The official invoice guide sets a $2,500 total invoice limit and excludes partial-payment invoices. The primary business and invoice location must be in the United States, excluding New York, U.S. territories, and sanctioned jurisdictions.
Crypto Waves: Industry Trends & Challenges
The Lightning Network is gaining steam, with companies like Bitrefill, Travala, and OpenNode already embracing it for gift cards, travel bookings, and payment processing. Square’s move stands out, though, given its reach—around 4 million merchants used its terminals when the feature was announced.
The Lightning Network tackles Bitcoin’s sluggish blockchain, which handles just seven transactions per second, causing high fees and delays. Off-chain transactions via Lightning offer near-instant settlements at a fraction of the cost, perfect for daily purchases. Still, hurdles like complex node management and security risks linger, but Square’s streamlined approach aims to ease these for merchants.
How the Community Reacted to the 2025 Announcement
At the time of Square’s announcement, the X community reacted with excitement:
- @Crypto_TownHall cheered, “JACK DORSEY SAYS SQUARE TO ACCEPT BITCOIN LIGHTNING PAYMENTS AT ALL TERMINALS,” hyping the fast, low-cost edge, with over 17,000 views and 89 likes.
- @fiatarchive blasted, “JUST IN: 💥 Square announces they will accept Bitcoin lightning payments at all terminals,” earning 13,892 views and 725 likes.
- @DiarioBitcoin raved, “Pagos instantáneos y comisiones casi nulas, directo desde tu móvil,” spotlighting instant payments and near-zero fees.
Those posts are historical snapshots of launch-day interest, not evidence of current merchant adoption. Current product terms should come from Square’s official documentation.
Square POS and Aurpay Online Payments Serve Different Needs
Aurpay’s non-custodial gateway supports Lightning payments to the merchant wallet. Aurpay provides no POS hardware, POS SDK, node hosting, channel management, Square integration, or automatic fiat settlement. Its fee is 0.8%.
The Future Is Bright: Bitcoin Goes Mainstream
Block’s rollout of Bitcoin Lightning payments to Square terminals marks a seismic shift, making cryptocurrency a practical choice for millions of merchants. The Lightning Network’s speed and low costs, paired with Square’s reach, could redefine everyday payments. Merchants should still compare the current limits, settlement choice, refund workflow, customer demand, and geography before enabling it.
