Practical overview

When it fits

Use ETC Explorer to inspect Ethereum Classic data through an explorer, or as a starting point for a self-hosted instance when you can provide Node.js, npm, MongoDB, and an Ethereum Classic node connection.

Who it is for

  • People who want to browse Ethereum Classic blockchain records through a block explorer.
  • Developers who want to configure or self-host an Ethereum Classic explorer.

Documented uses

  • Browse Ethereum Classic blockchain data through a web interface.
  • Sync and parse blockchain data into a MongoDB database.
  • Configure an explorer's node connection, block range, and synchronization behavior.
Before you choose

Requirements & limits

The repository is public and MIT-licensed. The README points to etherhub.io as a live version, but that reference does not confirm current availability.

  • The local setup depends on Node.js and npm, MongoDB, and a configured Ethereum Classic node endpoint.
  • The README documents separate processes for stats and rich-list functions.
  • The project offers both local installation and Docker setup instructions.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up ETC Explorer locally

Prepare the documented local installation and configure its blockchain data connection.

Before you start

  • Node.js and npm
  • MongoDB
  • An Ethereum Classic node endpoint, configured by node address and WebSocket port

Steps

  1. Clone the repository with the command below.

    Documented command
    git clone https://github.com/ethereumclassic/explorer

  2. Install the project dependencies with the command below.

    Documented command
    npm install

  3. Install MongoDB and copy the example configuration with cp config.example.json config.json.

  4. Edit config.json to set the node address, WebSocket port, block range, and desired sync settings.

Expected outcome

The project files, dependencies, database, and configuration are prepared for the documented run stage.

Guide limitations

  • This setup guide does not run the explorer or confirm that a node connection works.
  • The README's database installation examples are for macOS and Ubuntu.

Source-based practical guide

Start the explorer and blockchain sync

Start the web GUI together with the process that populates MongoDB with blockchain data.

Before you start

  • A prepared local installation
  • MongoDB
  • An Ethereum Classic node endpoint and configured config.json

Steps

  1. Run the command below to start both the web GUI and sync.js.

    Documented command
    npm start

  2. Alternatively, run the command below to run synchronization without app.js.

    Documented command
    npm run sync

Expected outcome

The documented commands start the combined web-and-sync process, or the sync process by itself.

Guide limitations

  • The README says database population fetches and parses the entire blockchain.
  • Stats and rich-list functions require separate processes; they are not started by these commands.
