+NIP-63
+======
+
+Pre-authed Filters
+------------------
+
+`draft` `optional`
+
+This NIP declares the use of event kind `33012` to represent one or more Nostr filters. 
+
+The `d` tag represents the subscription id and the `filter` tag describes a (NIP-01)[01.md] filter. 
+
+Supporting relays interpret the tags of this event as if they were submitted in the `REQ` scheme while automatically authenticating the signer. 
+
+They are submitted to the relay via `EVENT` messages instead of the usual `REQ` message.
+
+The goal is to be able to support `AUTH` from multiple users in the same connection while removing the usual `AUTH` round trip.
