people of san francisco, if you can make it, you should go see the uproarious @stamptown_ this upcoming weekend (sept 12-13): stamptowncomedy.com/shows2/2025/9/…
I think QR codes and MCP are going to pair nicely. Imagine you scan a code and your ai has access to that info and you can ask questions or take actions - restaurant menus - artwork in a museum URL is “the app”
Why L1 =>

1/ Launching Tempo Bridge was one of the first companies to use blockchains to solve core payments problems. During our journey, we’ve seen how even the most performant blockchains struggle with basic financial services use cases.
