Implements a Manifest V3 browser extension that verifies content directly on supported platforms (YouTube, Twitter/X, Instagram, GitHub, TikTok, LinkedIn) without page navigation.

Implementation

Core Components

  • Background service worker: API communication, 5-min cache, message routing
  • Content scripts: Platform detection, badge injection (YouTube/Twitter complete, 4 placeholders)
  • Popup UI: 5 verification states (loading, verified, not verified, unsupported, error)
  • Settings page: API config, wallet connection (MetaMask), privacy controls
  • Utils: Platform detector, API client, storage manager

Security Fixes

  • XSS prevention: Replaced innerHTML with createElement() + textContent in badge injection
  • URL encoding: URLSearchParams for query string construction
  • Platform detection: Exact hostname matching vs substring (hostname === "youtube.com" || hostname.endsWith(".youtube.com"))
  • Permissions: Restricted web_accessible_resources to 10 specific domains (was <all_urls>)

Example Badge Injection (YouTube)

// Before (vulnerable)
badge.innerHTML = `<p class="creator">Creator: ${verificationData.creator}</p>`;

// After (secure)
const creator = document.createElement("p");
creator.className = "creator";
creator.textContent = `Creator: ${truncateAddress(verificationData.creator)}`;
badge.appendChild(creator);

Documentation

  • extension/README.md - Installation, features, usage
  • docs/BROWSER_EXTENSION.md - Architecture, component design
  • extension/TESTING.md - 14 test cases
  • Security analysis, implementation summary

Status

Complete: Platform detection, YouTube/Twitter verification, popup, settings, wallet connection, security hardening (CodeQL: 0 alerts)
Pending: Instagram/GitHub/TikTok/LinkedIn implementations (placeholders ready), production icons, Chrome Web Store submission

    • Detect current platform (YouTube, Twitter, etc.)
    • One-click verification initiation
    • Auto-fill verification codes/links
    • Display verification status badges on platform pages
    • Quick access to Internet ID dashboard
  • Build extension UI (popup, options page, content scripts).
  • Handle wallet connection and signing within extension.
  • Add permission requests and privacy-conscious data handling.
  • Publish to Chrome Web Store, Firefox Add-ons, Safari Extensions.
  • Create extension demo video and screenshots.
  • Monitor usage analytics and error reports.
  • Document extension architecture and development setup.
