To initiate a connection, `client` shows the `starter iframe`. After a [`user gesture`](https://developer.mozilla.org/en-US/docs/Web/API/UserActivation), `starter iframe` interacts with `top-level signer`, acquires user confirmation and imports the private key to `iframe signer` storage.

When connection is established and private key is imported to `iframe signer` storage, `client` embeds invisible `worker iframe` and exchanges nip46 messages with it using a `MessageChannel`. After that `client` embeds invisible `worker iframe` and exchanges nip46 messages with it using a `MessageChannel`.
If `worker iframe` receives a request but has no target keys due to _ephemeral_ partitioned storage ([Brave](https://brave.com/privacy-updates/7-ephemeral-storage/), Webkit), it pauses the call and sends an error code to the `client`, which then shows the `rebinder iframe`. After a `user gesture`, `rebinder iframe` interacts with `top-level signer` and if `client` is already approved - imports the private key to `iframe signer` storage. At this point `worker iframe` can retry the paused call and send the reply back to `client`.

If `client` request must be confirmed by the user, `worker iframe` sends `auth_url` nip46 response, which is presented to the user as a visible `checker iframe`, instead of a popup as in nip46. This way `checker iframe` can access the request info stored by the `worker iframe`. After user confirms, `worker iframe` sends reply to `client`. If request must be confirmed by the user, `worker iframe` sends `auth_url` nip46 response, which is presented by `client` to the user as a visible `checker iframe`, instead of a popup as in nip46. After user confirms, `worker iframe` sends reply to `client`.
This NIP covers interactions between `client` and `iframe signers`. Interactions of `signer` frames (top-level/iframes) are up to implementations (see Appendix for recommendations).
