## Abstract

This document lists the types of messages that are using [MVDS](/vac/2/mvds.md)
in the Status application.

## Background

Status app uses MVDS to ensure messages going through Waku
are acknolwedged by the recipient.
This is to ensure that the messages are not missed by any interested parties.

## Message types

Various Message Types contain distinct information defined by the app
to facilitate convenient serialization and deserialization.

E2E reliability is a feature that ensures messages are delivered to the recipient.
This is initially achieved by using MVDS in Status.

Chat Type specifies the category of chat that a message belongs to.
It can be OneToOne (aka Direct Message), GroupChat, or CommunityChat.
These are the three main types of chats in Status.

| Message Type                                                               | Use MVDS                            | Need e2e reliability | Chat Type               |
