Status/Requirements

Software Requirements Specification

for Status: A Privacy-focused Crypto SuperApp

Version 1.0, Prepared by Jarrad Hope 2025-01-01

1. Introduction

1.1 Purpose

This Software Requirements Specification (SRS) document provides a detailed description of the Status SuperApp. It outlines the functional and non-functional requirements for developing a privacy-focused and crypto-centric application that combines secure messaging, financial services, and lifestyle features into a unified platform.

1.2 Document Conventions

This document uses the following conventions:

• MUST/REQUIRED - Indicates mandatory requirements for MVP (Minimum Viable Product)
• SHOULD/RECOMMENDED - Indicates requirements planned for subsequent releases
• MAY/OPTIONAL - Indicates optional features that could be implemented
• TBD - Indicates items that require further discussion or investigation

1.3 Intended Audience and Reading Suggestions

This document is intended for:

• Development Team: To understand technical requirements and implementation constraints
• Project Managers: To plan development phases and resource allocation
• Quality Assurance: To develop test plans and validation criteria
• UI/UX Designers: To understand interface requirements and user interaction flows
• Stakeholders: To verify that requirements align with project goals

1.4 Product Scope

Status is a privacy-focused SuperApp, the User Interface is generalised, providing secure environment for displaying and managing modules (similar to a browser, shell or window manager) and an application market and module management platform, (similar to Steam, Google Play, App Store) but specialized for crypto and privacy-focused applications. The core Status application MUST:

• Provide a secure window/app management system for displaying UI modules and data generated by them
• Provide a secure marketplace for discovering, installing, and managing UI modules
• Enable a vibrant ecosystem of third-party module development
• Implement robust module verification and trust mechanisms
• Facilitate seamless integration between modules
• Manage user accounts, authentication, and module permissions
• Coordinate system-wide notifications and inter-module communication

All functionality (messaging, financial services, etc.) MUST be implemented as modules, with the Logos Microkernel serving as the secure foundation for their operation. Core modules like DApp Browser, Content Discovery and Account Management are bundled with Status, while the platform enables easy discovery and installation of third-party modules.

This mini operating system application market approach creates an open ecosystem where developers can create and distribute modules while maintaining high standards of privacy and security. Status acts as a trusted platform for users to discover and use various crypto-economy services, similar to how Steam or App Stores provide a trusted platform for applications.

The ultimate goal is to create an accessible and secure user interface to the Crypto-economy, fostering a thriving ecosystem of privacy-preserving applications.

2. Overall Description

2.1 Product Perspective

Status is a SuperApp, a mini operating system that integrates with the Logos Microkernel ecosystem. Its primary role is to display UI modules and allow users to interact with them, similar to how an operating system shell provides an environment for applications. The framework enables functionality similar to:

• Secure messaging apps (Signal/Telegram) through messaging modules
• Financial services apps (Cash App/Venmo) through financial modules
• Super apps (WeChat/LINE) through its modular architecture

While Status operates independently, it relies on:

• Logos Microkernel for core functionality and module coordination
• PDMS for data management
• Modman for module package management
• Individual modules for specific features and services

2.2 Product Functions

Major framework functions include:

1. Core Framework Services
   • Module lifecycle management through Modman module (installation, updates, removal)
   • Window management and UI coordination
