> For customers, paying with bitcoin is as simple as scanning a QR code at checkout

Well yes but where's the rest of the owl? Is it assumed I already have some software ready to send my BTC via Lightning to the merchant's wallet? Does it only work if my BTC is managed by CashApp?

We built the pilot to show a standard lightning invoice with a QR code and NFC. Any wallet capable of paying that invoice could pay.

Whatever wallet you use did need to have liquidity on the network that can reach our routing node, c=, but we worked hard to make sure we had plenty of liquidity to all major wallets. I definitely recommended cashapp without shame at the conference, but I did a lot of testing with other wallets too. I never had much trouble, even with non-custodial lightning wallets.

Lightning is a layer two protocol on Bitcoin. It supports any Lightning wallet including CashApp.
