I looked at this space about 3 years ago, what I want seems to still not exist

I am looking to sell physical goods for low total amounts (<$10 usd) via a website. The most basic e-commerce you can imagine.

In particular, what I want:

- fast-ish payments (settlement in <2hr)

- low/zero per-payment cost, low % fee

- your average HN user could figure out how to use it to pay

What I don't need:

- subscriptions

- payment-level fraud protection

- payment-level kyc

- customer financing (a la Klarna)

- rev rec

It seems like Fednow or lightning would meet some (most?) of these requirements, but I have not yet seen it in the wild.

Tempo might be good for this once it comes out.

Does stablecoin send/receiving via stablecoins or Lightning not work? Is it too difficult to get a user to pay? x402 should work just fine?
