How to run Guru Network Indexer



Ensure you have the following installed:

  • Docker

  • Docker Compose

Step-by-Step Instructions

  1. Prepare Environment Variables

    • Copy the env.sample file and rename it to .env.

    • Edit the .env file to set the following variables according to your needs:

      • CHAIN_ID: The ID of the blockchain network you are indexing.

      • DATABASE: The name of the database that will be created in ClickHouse.

      • PROVIDER_URL: The URL of your RPC provider, such as a public node, Infura, or a local node.

    • See Environment Variables

  2. Start Indexing

    • Open your terminal and navigate to the directory containing your docker-compose.yml file.

    • Run the command:

      docker-compose up
    • This command will start indexing the Ethereum blockchain into ClickHouse.

  3. Verify Database Content

    • Once the indexing process begins, you can inspect the database to see the tables created for each entity type and a few service-related tables.

pip3 install -r requirements.txt
