Getting Started with ERC20-Exporter

Let’s dive into how you can get ERC20-Exporter running on your local machine. Please ensure you have the following prerequisites:

  • Supported OS: Ubuntu 16.04
  • Ethereum backend nodes: Parity, Geth (untested)

Step-by-Step Installation Process

  1. Set up a NodeJS and npm environment on your machine.
  2. Install the latest version of the Parity Ethereum client.
  3. Start Parity using the command: parity --warp
  4. Clone the ERC20-Exporter repository to your local machine:
  5. git clone https://github.com/gobitfly/erc20-exporter
  6. Install all dependencies using:
  7. npm install
  8. Rename config.js.example to config.js and adjust the settings to your local environment.
  9. Start the explorer with:
  10. npm start
  11. Open your browser and navigate to http://localhost:3000.

Note: For larger tokens, the initial data export can take up to 30 minutes. After the export, it’s advisable to change the exportStartBlock parameter in the config file to a block number around 30,000 blocks behind the current chain tip and restart the exporter.

Understanding the Code: An Analogy

Imagine you are hosting a party (that’s your ERC20-Exporter) and your friends (representing the transactions and accounts data) are coming from different neighborhoods (Ethereum nodes). Instead of building a permanent structure to store their information, you allow them to come in, grab a drink, and leave—the data flows in real-time and does not remain stored. Just like a host relies on responding to his visitors as they arrive, ERC20-Exporter relies on the live response of the Ethereum node, giving you updated insights without any hindrance.

Troubleshooting Tips

If you encounter issues while setting up ERC20-Exporter, consider the following troubleshooting steps:

  • Ensure NodeJS and npm are properly installed and updated.
  • Check your Parity installation and ensure it’s running with the correct parameters.
  • Verify that you have cloned the correct repository and installed all dependencies.
  • Revisit your config.js settings for any misconfigurations.
