Setting up your workstation

This first guide will walk you through a step-by-step installation of the required tools to start developing applications on Bitxor.

We will be using the test network, which uses the same technology and features of the main network. The testnet allows developers to experiment with the offered Bitxor’s transaction set in a live network without the loss of valuable assets.

Creating an account

An account is a deposit box where you can hold tokens (tokens) and interact with them by announcing transactions.

We are creating a new account with the Bitxor CLI, a command-line tool designed to architect solutions and interact with Bitxor networks in an efficient manner.

  1. Bitxor CLI requires Node.js 12 LTS to execute. Open a new terminal and check the version installed with:

    node --version

    If you get an error or the version returned does not match v12.X, visit nodejs.org to install the requirement (Although it is recommended to install through nvm).

  2. To install Bitxor CLI, run the next command.

    npm install --global bitxor-cli

  3. Then, generate a new account and save it as a profile.

    bitxor-cli account generate

Enter network type (MAIN_NET, TEST_NET): TEST_NET
Do you want to save the account? [y/n]: y
Select an import type: » PrivateKey
Enter Bitxor Node URL. (Example: http://localhost:3000): <NODE_URL>
Insert the profile name: testnet
Do you want to set the account as the default profile? [y/n]: y

  4. If everything goes well, you should see the account credentials displayed in the terminal.

    Profile stored correctly

├─────────────┼──────────────────────────────────────────────────────────────┤
│ Private Key │ AAA...AAA                                                    │
└─────────────┴──────────────────────────────────────────────────────────────┘

    Note

    Make sure to keep the private key secret and backed up safely somewhere offline.

If you get the error The CLI cannot reach the node, the most common causes are:

  • Incorrect node URL: The URL used does not belong to an active node. Open the URL provided in a new browser tab and check if you get a response. If the test network node is not working, you can use another node url from this list or run your own testnet node by following the next guide.

  • Internet connection: The CLI resolves some values from the node. If you decide to use the tool without being connected to the internet, you will have to pass the options --network, --generation-hash, --namespace-id, and divisibility. Type bitxor-cli account generate --help to know more about each parameter.

Getting test currency

To announce a transaction, the sender should pay a fee to provide an incentive to those who validate and secure the network and run the infrastructure. This cost is paid in bitxor tokens, the default network currency of the public network.

Now that you have created your first account, let’s request bitxor units from the testnet faucet. Navigate here, indicate the amount of bitxor you want to receive and the address, and click “CLAIM!”.

After the transaction gets confirmed, check if your account has received bitxor using the command-line tool.

bitxor-cli account info --profile testnet

Balance Information
┌──────────────────┬─────────────────┬─────────────────┬───────────────────┐
│ Token Id        │ Relative Amount │ Absolute Amount │ Expiration Height │
├──────────────────┼─────────────────┼─────────────────┼───────────────────┤
│ 5E62990DCAC5BE8A │ 750.0           │ 750000000       | Never             │
└──────────────────┴─────────────────┴─────────────────┴───────────────────┘

Note

The faucet has a limited amount of bitxor and must be replenished before it dries out. If you don’t need your test bitxor units anymore, please send them back to the account indicated in the faucet’s page.

Creating a project

Now that you have your account filled with bitxor units, it is time to choose a programming language. Pick the one you feel most comfortable with, or follow your project requirements.

Then, create a folder for your new project and run the instructions for the selected language. If none of the languages fits your project, you can always query the blockchain directly using the REST gateway.

Note

Bitxor SDK requires Node.js 12 LTS to execute.

  1. Create a package.json file.

    npm init

  2. Install Bitxor SDK and RxJS library.

    npm install bitxor-sdk rxjs

  3. Install globally TypeScript dependency:

    npm install --global typescript
typescript --version

  4. Install ts-node to execute TypeScript files with node.

    sudo npm install --global ts-node
