Square is enabling Bitcoin Lightning payments by default: What it means for spending Bitcoin in 2026

From March 30, 2026, Square will switch Bitcoin Lightning payments on by default for all eligible merchants globally. Around 4 million businesses using Square terminals will accept Bitcoin without needing to do anything, no new hardware, no manual opt-in. It's the largest single expansion of Lightning-enabled retail in the network's history.

If you hold Bitcoin and want to spend it, this is worth paying attention to. Lightning makes Bitcoin fast enough and cheap enough to use for everyday purchases. Here's what changed, how Lightning works, and where you can spend Bitcoin with Lightning right now.

What Square announced

Square sent merchants an updated Terms of Service in March 2026 confirming the change. From March 30, Bitcoin Lightning payments are on by default for eligible sellers. Merchants can hold the Bitcoin, auto-convert to local currency at checkout, or turn the feature off entirely.

For customers, paying works the same way it does on any Lightning-enabled platform: scan a QR code at checkout, confirm in your wallet, done. The payment settles in seconds.

Bitcoin payments on Square are free through 2026. From 2027 a 1% flat fee applies, well below the 2 to 3% standard card processing rate most merchants currently pay.

How Bitcoin Lightning payments work

Regular Bitcoin transactions settle on-chain. Every transaction gets broadcast to the full network, confirmed by miners, and written to the blockchain. That process takes minutes and costs fees that vary with network congestion, sometimes low, occasionally expensive.

The Lightning Network is a second layer built on top of Bitcoin. Payments move through off-chain payment channels between wallets, which means they confirm in seconds and cost fractions of a cent. The final balance settles on-chain when a channel closes, but day-to-day transactions never touch the main blockchain.

That's what makes Lightning suitable for small, everyday purchases like buying a gift card, topping up a phone, or paying at a coffee shop. On-chain Bitcoin was never built for that. Lightning is.

2. At checkout, select BTC and choose Lightning as the network.

Lightning wallets that work on Cryptorefills

Phoenix, Wallet of Satoshi, Muun, and BlueWallet are all reliable options on mobile. Any wallet that supports standard BOLT11 invoices will work.

Why this matters beyond Square

Square's move doesn't change what Lightning can do. It changes how many people will encounter it for the first time. A customer who pays with Lightning at a café on March 30 now has a mental model for how it works. The next time they see a Lightning payment option on Cryptorefills or any other platform, it's familiar rather than foreign.

That's the real significance. Lightning has been technically ready for everyday spending for years. Square's default rollout is the mainstream distribution moment that puts it in front of people who never sought it out.
