⚡ Stratum Overlay (stratum-rs-overlay)

High-Performance, DLL-Injection Free Game Overlay Library for Electron. > Powered by Rust 🦀 + N-API.

Stratum Overlay is a specialized library designed to create invisible, click-through overlays for Windows applications using Electron. Unlike traditional methods, it does not inject DLLs into game processes, making it safer and more compatible with anti-cheat systems.

🚀 Key Features

• 🛡️ Anti-Cheat Friendly: Uses external window overlay method. No memory writing or code injection.
• ⚡ Blazing Fast: Core logic written in Rust for minimal overhead and maximum performance.
• 🖱️ Click-Through Support: Perfectly handles mouse events, passing clicks to the game behind the overlay.
• 🔒 Secure Licensing: Built-in license verification system powered by Ed25519 cryptography.
• 🪟 Windows Native: Fully optimized for Windows (x64) using native Win32 APIs.

📦 Installation

npm install stratum-rs-overlay

Note: This library currently supports Windows (x64) only.

2. Integration in Electron

Add the following code to your Electron Main Process (main.js):

const { app, BrowserWindow } = require('electron');
const stratum = require('stratum-rs-overlay');

// Load environment variables (Recommended)
require('dotenv').config();

const LICENSE_KEY = process.env.STRATUM_LICENSE_KEY || "YOUR_LICENSE_KEY";

function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    transparent: true,    // Required
    frame: false,         // Required
    alwaysOnTop: true,    // Recommended for overlays
    webPreferences: {
      nodeIntegration: true,
      contextIsolation: false,
    },
  });

  win.loadFile('index.html'); // or loadURL(...)

  // ---------------------------------------------------------
  // 🔐 1. Initialize & Verify License
  // ---------------------------------------------------------
  console.log("🔑 Verifying License...");
  const isVerified = stratum.init(LICENSE_KEY);

  if (isVerified) {
    console.log("✅ License Verified! Activating Overlay...");

    // -------------------------------------------------------
    // 🖱️ 2. Enable Click-Through Mode
    // Pass the native window handle (HWND) to Rust
    // -------------------------------------------------------
    const hwnd = win.getNativeWindowHandle();
    stratum.setClickThrough(hwnd);
    
    console.log("✨ Overlay Mode: ACTIVATED");
  } else {
    console.error("❌ License Verification Failed.");
    console.error("   - Overlay features are disabled.");
    // Handle invalid license (e.g., show error dialog or quit)
  }
}

app.whenReady().then(createWindow);
