Installation

ParallelChain client (pchain_client) is a command-line tool that allows you to connect and interact with the ParallelChain Mainnet / Testnet. pchain_client supports both Windows and Linux/macOS. In this tutorial, we will provide you with step-by-step instructions on how to install and use pchain_client to transfer tokens, deploy smart contracts, and call contracts.

Installation Instructions

Windows

  1. Download the latest release as a compressed file from Assets of ParallelChain Lab's GitHub release page.
  2. Unzip the file to extract the executable pchain_client.exe.
  3. Open Powershell by pressing WIN+R and typing powershell.
  4. Navigate to the directory where pchain_client.exe is located using the cd command. For example, if the executable is located at C:\Development, type cd C:\Development.
  5. Follow the instructions in Section Prepare Environment to get ready for interacting with the blockchain.

Linux / macOS

The installation process for Linux and macOS is similar. To install pchain_client:

  1. Download the latest release as a compressed file from Assets of ParallelChain Lab's GitHub release page.

  2. Head to the directory where the downloaded file is located and extract it using tar. For example:

    tar -xvf pchain_client_linux_v0.4.3.tar.gz 

    tar -xvf pchain_client_mac_v0.4.3.tar.gz

  3. Follow the instructions in Section Prepare Environment to get ready for interacting with the blockchain.

Tips

  • If you're using macOS and encounter a GateKeeper message when trying to run pchain_client, you can remove macOS' "GateKeeper" attributes from pchain_client using the following command: 

    sudo xattr -rd com.apple.quarantine ./pchain_client
    This is an elevated action, so you will need to enter your password to continue. pchain_client can now be used as normal.

  • You might want to store pchain_client in a directory of your choice so that it is easier to follow the commands in the tutorial. For example, we created a folder in our home directory called parallelchain_client: 

    $ mkdir -p /home/my_user/parallelchain_client
$ cp pchain_client /home/my_user/parallelchain_client/
$ cd /home/my_user/parallelchain_client
$ ./pchain_client
