 ```

+To be able to simulate nested messages within a transaction, message types containing nested messages must implement the
+`HasNestedMsgs` interface. This interface requires a single method: `GetMsgs() ([]sdk.Msg, error)`, which should return
+the nested messages. By implementing this interface, the BaseApp can simulate these nested messages during
+transaction simulation.
