 `draft` `optional` `author:atxmj`
 
+This NIP standardizes the approach to payment and tip invocations from user profiles, posts, chats, and elsewhere using the [RFC-8905 (payto:) URI scheme](https://www.rfc-editor.org/rfc/rfc8905.html) standard for "payment targets".

 ### payto: event broadcasting
 
 Clients *may* allow users to specify a list (one or many) of "payment targets" as specified in the [RFC-8905 (payto:) URI scheme](https://www.rfc-editor.org/rfc/rfc8905.html) standard, each consisting of a pair of values, `payment_target_type` and `authority` (to be labeled as preferred by the client), in order to generate an event of kind `0` (`set_metadata`) specifying "payment targets" that *may* be used for payment or tip invocation from a user's profile, posts, chats, or elsewhere.
