+Custom Emoji Reaction
+---------------------
+
+The client may specify a custom emoji ([NIP-30](30.md)) `:shortcode` in the
+reaction content. The client should refer to the emoji tag and render the
+content as an emoji if shortcode is specified.
+
+```json
+{
+  "kind": 7,
+  "content": ":soapbox:",
+  "tags": [
+    ["emoji", "soapbox", "https://gleasonator.com/emoji/Gleasonator/soapbox.png"]
+  ],
+  "pubkey": "79c2cae114ea28a981e7559b4fe7854a473521a8d22a66bbab9fa248eb820ff6",
+  "created_at": 1682790000
+}
+```
+
+The content can be set only one `:shortcode:`. And emoji tag should be one.
