Nostr stores should support cashu payments sent in secure DMs. Buyer can reclaim the payment if seller doesn't reply. Seller doesn't need a payment processing or e-commerce server, mobile phone is enough. Maybe the cheapest and easiest way to run a small online store. Some sort of order management UI for buyer and seller on the client side would be nice. Just thinking aloud, only tried Shopstr so far but should check out others as well (Amethyst?) Pic kind of related, could be my dropshipping lifestyle store. image

Why? To accept it you need to instantly convert it to lightning anyway to make sure it’s “real”. At that point why not use lightning to begin with?

Seller can claim it immediately when he sees and accepts the order, but buyer has some protection from ghosting. With cashu, any server (or even the buyer) does not need to be online at the time of purchase.

Imagine you give your waiter a tip or gift someone else some sats via cashu as a present. If you see then after xyz time that they still have not redeedem your gift you can just take them back instead they getting lost/unused. Obviously as soons as they are accepted/reedem you can't get them back. So I guess what @Martti Malmi was saying is e.g. I could send you know now 100k sats in cashu via DM and say please build xyz into damus. And if you don't want or ignore my request I could always get my sats back without having to ask for a refund.

so its explicitly designed to be doublespend + rugpull tech. makes sense. I guess that is technically a feature for the sender

I don’t see how it’s good for scalability and privacy where there are glaring payment finality issues when actually using this in practice for commerce.

In traditional e-commerce (paid with lightning or credit card), checkout fails if any of these has even a temporary connection problem: buyer's personal device, buyer's lightning wallet / cc, seller's e-commerce server, seller's wallet / cc processing. Nostr & cashu can do it better.

You can think of one or many Cashu payments as a deferred Lightning payment. Especially useful for asynchronous transactions: A merchant can always accept ecash from any mint and, depending on their appetite, either swap out to mints they trust or to a non-custodial Lightning wallet when they come back online and need to process orders. As a merchant, you can't get rugged if you never received the actual payment. On the other hand, sellers can also define the mints they require a token to be from (Cashu payment requests contain this information). That way, the sender is expected to get ecash from a specific mint (typically using Lightning). These transactions are typically instant.

Hey! Because it allows an asynchronous yet automatic checkout flow. Otherwise the merchant (or an agent controlling their nsec) needs to be present to generate a Lightning invoice and finalize the transaction. It’s a really cool part of the @Gamma Markets spec that @calvadev⚡️ is already using for Nostrized e-commerce. Yes it requires an extra step to get back to Lightning that seems redundant, and trust in an ecash mint, but it takes the burden off the merchant to run an ever-present server for automatic checkout.

We look forward to a future where digital goods like eSIMs, VPNs, and gift cards can be purchased with ecash sats and LN sats through mini apps on Keychat, with sellers automating payments and sending the goods via DM.
