> 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?

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