Launching a Block Explorer


This short guide will help you setup a local blockchain explorer. This will enable you to browse and search your local Testnet (or any other ARK based) blockchain from a web application (exactly the same as in our official Blockchain Explorer ).

Blockchain Explorer communicates with the local Core node via the Public REST API interface, so make sure it is enabled (default value is enabled).

For production deployment and customization options head over here:

How To Deploy Blockchain Explorer?

STEP 1: Clone Official Explorer Repository

git clone
cd explorer

STEP 2: Install Package Dependencies

From the explorer root folder runyarn install command. This will build and install the required modules and packages.

STEP 3: Run Your Local Explorer

There are several run modes available for the Explorer package. You can run it as official Mainnet or Devnet explorer, or have it run as a simple local express server, it is up to your needs.

More detailed information about all possible running modes can be found in the Explorer Documentation section.

For our simple task of viewing, browsing and searching the local Testnet blockchain, all we need to do is run the following command from the Explorer root folder:

yarn serve:testnet

This command will start the Explorer in dev mode and it will search for a localhost core node, that should be running on by default.

After running yarn serve:testnet command, you should see the following:

DONE  Compiled successfully in 11030ms

    App running at:
        - Local:   http://localhost:8080/
        - Network:

    Note that the development build is not optimized.
    To create a production build, run yarn build.

Head over to http://localhost:8080/ to view contents of local running blockchain with Testnet environment setup.
