Cool to see this! I had been wondering what was up with Oshi and Michael lately.
The plug in stack grew around that idea. Square, Shopify, WooCommerce, Stripe, Zaprite, and others let Oshi watch purchases and reward customers in sats. Merchants can appear on an Oshi marketplace map, so Bitcoiners can seek them out, but the core loop is simple: buy normal goods, earn bitcoin, come back again.
