Decentraland Launcher (Rust)

Project Overview

The Decentraland Launcher (Rust) is a cross-platform desktop application that manages the installation and launching of the Decentraland client (Explorer). It is built with Rust and Tauri for performance, security, and a smaller binary footprint. The launcher ensures users always run the latest version of the Explorer by handling download, installation, and startup logic.

Features

• Automatic updates for Decentraland Explorer
• Cross-platform support (Windows, macOS)
• Lightweight architecture using Rust and native system WebViews
• URI scheme support: decentraland://
• Secure download and launch process
• Unified frontend-backend communication via single union-type enum

Architecture Overview

The architecture uses:

• Rust (core): Handles system-level logic such as update checks, downloads, and launching the Explorer.
• Frontend (TypeScript): Renders the UI via Tauri using web technologies.
• Tauri bridge: Facilitates IPC between frontend and backend.
