What is CompactSee?

CompactSee is a web application that connects to Midnight's testnet indexer to provide real-time monitoring of smart contract events. Simply enter a contract address, and CompactSee will:

• Monitor contract events in real-time via WebSocket connection
• Display contract state changes with detailed, readable formatting
• Track deployment, calls, and updates to your contracts
• Provide a clean interface to browse through event history
• Auto-disconnect after 5 minutes to prevent resource leaks

Why is CompactSee Useful?

For Developers

• Real-time debugging: See contract events as they happen during development and testing
• State inspection: View contract state changes in a human-readable format
• Event tracking: Monitor contract deployments, calls, and updates without manual blockchain exploration
• Testing workflow: Quickly verify contract behavior during development cycles

For Midnight Ecosystem

• Developer tooling: Provides essential monitoring capabilities for Midnight smart contract development
• Network transparency: Makes contract activity visible and accessible
• Educational resource: Helps developers understand how Midnight contracts behave in practice

Features

• 🔗 Real-time WebSocket connection to Midnight testnet indexer
• 📊 Event visualization with clean, organized interface
• 🔍 State inspection with formatted contract state display
• ⏱️ Automatic timeout (5 minutes) to prevent resource leaks
• ⚡ Fast and efficient Rust-based backend with Leptos frontend

Technology Stack

Getting Started

CompactSee is designed to work with Midnight testnet contracts. Simply:

1. Enter a valid Midnight testnet contract address
2. Click "Connect" to start monitoring
3. View real-time events and state changes
4. The connection automatically times out after 5 minutes

Test Contract Address

To quickly test CompactSee, you can use this sample contract address:

0200cc2f4e37bb554c344c04aff7ad746d8df129a4985d3908b509712b4cd721f163

Perfect for developers building on Midnight who need to monitor their smart contracts during development and testing phases.
