Building a Hedera Hashgraph Crypto Wallet using Node.JS

If you are interested in building a crypto wallet that interacts with the Hedera Hashgraph network using Node.JS, you have come to the right place. In this article, we will walk you through the process of creating a simple crypto wallet that can send and receive HBAR tokens on the Hedera Hashgraph network.

Setting up the Environment

First, you will need to install Node.JS on your computer if you haven’t already. You can download and install Node.JS from the official website (https://nodejs.org/). Once Node.JS is installed, you can check the version by running the following command in your terminal or command prompt:

node -v

Next, you will need to create a new directory for your project and initialize a new Node.js project using the following command:

mkdir hbar-wallet
cd hbar-wallet
npm init -y

Connecting to the Hedera Hashgraph Network

In order to interact with the Hedera Hashgraph network, we will use the hedera-sdk package, which provides a set of tools for building applications on the Hedera network. You can install the hedera-sdk package using the following command:

npm install @hashgraph/sdk

Once the package is installed, you can start writing the code for your crypto wallet. Here is a simple example of how to create a new HBAR address and check the balance:

const { Client } = require("@hashgraph/sdk");

async function main() {
  const client = Client.forTestnet();
  client.setOperator(process.env.ACCOUNT_ID, process.env.PRIVATE_KEY);

  const balance = await new AccountBalanceQuery()
    .setAccountId(process.env.ACCOUNT_ID)
    .execute(client);

  console.log("Balance:", balance.hbars.toTinybars());
}

main();
  

With this code, you can create a new HBAR address and check the balance of the account. You can then expand upon this code to create additional functionality for sending and receiving HBAR tokens.

Conclusion

Building a crypto wallet for the Hedera Hashgraph network using Node.JS is a great way to get started with blockchain development. By following the steps outlined in this article, you can create a simple crypto wallet that interacts with the Hedera network and perform basic operations such as sending and receiving HBAR tokens.
