HCU Reset Tracker

A simple web application that tracks and visualizes progress towards a target block height on the Flow blockchain. This tool is useful for monitoring the difference between current and target block height during Height-Coordinated Upgrade (HCU) on the Flow network.

Features

  • Real-time Block Height Tracking: Automatically fetches and displays the current block height from Flow's blockchain
  • Network Selection: Toggle between Mainnet and Testnet
  • Progress Visualization: Visual progress bar that changes color as you approach the target
  • Copy Functionality: One-click copy for current block height
  • Auto-refresh: Continuous tracking with automatic updates every second

Usage

  1. Select Network: Choose between Mainnet or Testnet using the dropdown
  2. Get Current Height: Click the "Get Current Height" button to display the current block height
  3. Set Target Height: Enter your target block height in the input field
  4. Start Tracking: Click "Start Tracking" to begin monitoring the progress
  5. Stop Tracking: Click "Stop Tracking" to pause the monitoring

The application will automatically calculate the remaining blocks and display the progress visually.
