 async window.nostr.signEvent(event: Event): Event // takes an event object and returns it with the `sig`
-async window.nostr.getRelays(): { [url: string]: {read: boolean, write: boolean} } // returns a map of relay urls to relay policies

+Aside from these two basic above, the following functions can also be implemented optionally:
+```
+async window.nostr.getRelays(): { [url: string]: {read: boolean, write: boolean} } // returns a basic map of relay urls to relay policies
+async window.nostr.nip04.encrypt(pubkey, plaintext): string // returns ciphertext and iv as specified in nip-04
+async window.nostr.nip04.decrypt(pubkey, ciphertext): string // takes ciphertext and iv as specified in nip-04
 ```
 
 ### Implementation
 
 - [nos2x](https://github.com/fiatjaf/nos2x) is available as a Chromium extension that provides such capabilities.
 - [Alby](https://getalby.com) is a Bitcoin extension that also provides a compatible `window.nostr`.
