I wanted to prove to myself that postMessage would be a viable way to communicate between an app and the keyring site, so I created two example apps and got them to talk to eachother. to try this out, in two different consoles run: console a: ``` cd examples/react/fake-keyring pnpm install pnpm run dev ``` console b: ``` cd examples/react/fake-keyring pnpm install pnpm run dev ``` then head to `http://localhost:3000` and hit "grab the keys" you should see output in the console confirming this cross-origin communication works as expected, with some TODOs that sketch out what the keyring might need to do to make this all work as expected. big open question for me - does the UCAN need to be transmitted all the way back to the app domain or can we just store it on the server as proof that a user has granted a domain access to a particular set of capabilities?

It probably depends on context, but in general I think we want more the former than the latter. Give the end-user (or their user-agent aka web browser) the delegation so they are in control of it. Don't hide it from them by storing it on their server without them having a copy. |

to try this out, in two different consoles run:
console a:
console b:
then head to
http://localhost:3000and hit "grab the keys"you should see output in the console confirming this cross-origin communication works as expected, with some TODOs that sketch out what the keyring might need to do to make this all work as expected. I'm not entirely sure why the handler gets registered multiple times, but that's not super important for now.

this should probably never be merged - close it when we no longer need it handy
