Getting Started


Ensure that JRE 1.8 or higher is installed in your system. Also, ensure that 8080 TCP port is free.


Download the MSI installer from releases page and double click on it. As the installer is currently unsigned, this causes red alert during the installation. Do not worry: it's OK.

Linux and macOS

We've prepared a universal installation script. Just run this command in your terminal.

curl -sL | bash

Write Your First Pravda Program

Importing the Project Template

To use the project template, you will need .NET Core SDK 2.1. Create a directory for your project and run inside it:

dotnet new -i Expload.PravdaProgramTemplate
dotnet new pravdaprogram --namespace MyTeam --version 1.0.0 --name HelloProgram

Now your directory contains: - HelloProgram.cs - main program file. By default it contains simple program with HelloWorld method - HelloProgram.csproj - project configuration. It includes scripts for compiling and deployment, as well as .NET dependencies & metadata - - feel free to consult it whenever you feel confused

You can also check out the section Hello World that contains a more complex sample of a Pravda program.

Compiling the Program

To compile C# code into pravda binary run:

dotnet publish -c Debug

Now you have MyProject.pravda in your project directory. You can use local node and Pravda CLI commands to deploy to a local node or proceed further to work with Expload Playground.

Deploying to Expload Playground

Preparing Wallets

If you have no wallet.json yet

First, you have to generate a wallet and put it into the wallet.json file.

pravda gen address -o wallet.json

Then use Playground-Faucet to credit a certain amount of XPlatinum to your wallet.

If you already have a wallet with the sufficient amount of XPlatinum for the deployment operation

Just put your wallet into the wallet.json file in the current folder.

Note. If you don't have the sufficient amount of XPlatinum, just get some funds using Playground-Faucet.

If you have no program-wallet.json yet

Generate a wallet and put it into the program-wallet.json file.

pravda gen address -o program-wallet.json

Open the program-wallet.json file and remember the address field — this is your future program's address.

If you already have a program-wallet.json

Just put your file program-wallet.json into the current folder.


Finally, run:

dotnet publish -c Deploy

Now your program is on the Expload Playground net!

If you want to update the program, run

dotnet publish -c Update

For more information on working with the template, see in your project directory.

Set Up Your Own Pravda Testnet

Configure Initial Coin Distribution

Before you can run a local node, you should build the initial coin distribution config.

pravda gen address -o my-wallet.json

This command will generate a ED25519 key pair. This is a valid Pravda wallet. Now you can add an address to the coin distribution config.

    "address": "address from my-wallet.json",
    "amount": 1000000000

Save this to my-coin-distribution.json. Now let’s initialize the node configuration.

Initialize the Pravda Node

pravda node init --local --coin-distribution my-coin-distribution.json

Congrats! The configuration is written to the pravda-data/node.conf directory (also, you can choose the data directory using --data-dir key). Now let's run the node.

Run the Pravda Node

pravda node run

Now you have your own Pravda network with one validator and funds on your account. Check out http://localhost:8080/ui.

Transfer Coins

You may now want to donate a part of your wealth to another user. Let's generate a wallet for them.

pravda gen address -o another-wallet.json

A wallet for the user has been created. Now let's copy this address and transfer some coins.

pravda broadcast transfer \
  --wallet my-wallet.json \
  --to <address-of-poor-guy> \
  --amount 1000000

The funds have been credited. Great job!
