Ethereum Lite Explorer

Use the Ethereum Lite Explorer to explore blockchain data at the block, transaction, and account level.

The Ethereum Lite Explorer is a client-side only web application that connects to any Ethereum JSON RPC enabled node. No server, hosting, or trusting third parties to display the blockchain data is required.

!!! note The Ethereum Lite Explorer is an Alethio product.

Prerequisites

Docker or npm

Run Using Docker

To run the Lite Explorer using the Docker image:

1. Start Pantheon with the --rpc-http-enabled option.

   !!! example

    To run Pantheon in development mode:
   
    ```bash
    pantheon --network=dev --miner-enabled --miner-coinbase=0xfe3b557e8fb62b89f4916b721be55ceb828dbd73 --rpc-http-cors-origins="all" --host-whitelist="all" --rpc-http-enabled --data-path=/tmp/tmpDatdir
    ```
   

2. Run the alethio/ethereum-lite-explorer Docker image specifying the RPC HTTP URL (http://localhost:8545 in this example):

   docker run -p 80:80 -e NODE_URL=http://localhost:8545 alethio/ethereum-lite-explorer
   

3. Open localhost in your browser to view the Lite Explorer.
