About

OrdNexus is a browser extension that provides seamless CORS-free network access for Bitcoin and blockchain applications.

🔥 KEY FEATURES
• Universal CORS proxy for Bitcoin API calls
• Silent background fetching (no popups!)
• 30-second intelligent caching
• Works with mempool.space, blockchain explorers, and Bitcoin nodes
• Zero configuration required

🎯 PERFECT FOR
• Bitcoin ordinals creation
• Blockchain data fetching
• Bitcoin transaction broadcasting
• UTXO management
• Fee rate monitoring

⚡ HOW IT WORKS
OrdNexus runs silently in the background and provides a simple API (window.NexusBrowserExtension) that web applications can use to make unrestricted network requests. This eliminates CORS errors and popup windows when interacting with Bitcoin APIs.

🔒 PRIVACY & SECURITY
• No data collection or tracking
• All requests made directly from your browser
• Open source code available
• Minimal permissions (only what's needed for CORS bypass)

💡 USE CASE
Designed for Nexus OCW (Ordinals Creation Workbench) and compatible with any web application that needs CORS-free access to Bitcoin APIs.
