# Transfer HBAR

## Prerequisites <a href="#pre-requisites" id="pre-requisites"></a>

* Completed the Introduction step.
* Completed the Environment Setup step.
* Completed the Created an Account step.

## Step 1 : Imports

* The script imports necessary modules from the Hedera JavaScript SDK: `Client`, `AccountBalanceQuery`, `TransferTransaction`, `Hbar`, and `PrivateKey`.
* It also imports the `dotenv` module to load environment variables from a `.env` file located in the `Account` directory.

```javascript
const {
    Client,
    AccountBalanceQuery,
    TransferTransaction,
    Hbar,
    PrivateKey 
} = require("@hashgraph/sdk");
require('dotenv').config({ path: 'Account/.env' });

```

## Step 2 : **Environment Variables Retrieval**

These lines retrieve environment variables such as `MY_ACCOUNT_ID`, `MY_PRIVATE_KEY`, and `OTHER_ACCOUNT_ID` from the `.env` file using `process.env`.

```javascript
const myAccountId = process.env.MY_ACCOUNT_ID;
const myPrivateKey = PrivateKey.fromString(process.env.MY_PRIVATE_KEY);
const otherAccountId = process.env.OTHER_ACCOUNT_ID;
```

## Step 3 : **Main Function**

* It creates a client instance for the Hedera testnet and sets the operator account using the user's account ID and private key.
* It creates a `TransferTransaction` object to transfer HBars between accounts.
* The transaction subtracts 10 HBars from the operator account (`myAccountId`) and adds 10 HBars to the other account (`otherAccountId`).
* The transaction is executed, and the resulting transaction ID (`txId`) is obtained.
* The receipt of the transaction is retrieved, and the transaction consensus status is obtained from the receipt.
* Queries are created to retrieve the account balances of both the operator account and the other account.
* The queries are executed, and the account balances are logged to the console.

```javascript
async function main() {
    const client = Client.forTestnet(); // Create a client for the Hedera testnet
    client.setOperator(myAccountId, myPrivateKey); // Set the operator account for the client

    const transaction = new TransferTransaction() // Create a transfer transaction
    .addHbarTransfer(myAccountId, new Hbar(-10)) // Subtract 10 HBars from the operator account
    .addHbarTransfer(otherAccountId, new Hbar(10)); // Add 10 HBars to the other account

    console.log(`Doing transfer from ${myAccountId} to ${otherAccountId}`);

    const txId = await transaction.execute(client); // Execute the transfer transaction
    const receipt = await txId.getReceipt(client); // Get the receipt of the transaction
    const transactionStatus = receipt.status; // Get the transaction consensus status

    console.log("The transaction consensus status is " + transactionStatus);

    const queryMine = new AccountBalanceQuery().setAccountId(myAccountId); // Create a query for operator account balance
    const queryOther = new AccountBalanceQuery().setAccountId(otherAccountId); // Create a query for other account balance

    const accountBalanceMine = await queryMine.execute(client); // Execute the query for operator account balance
    const accountBalanceOther = await queryOther.execute(client); // Execute the query for other account balance

    console.log(`My account balance ${accountBalanceMine.hbars} HBar, other account balance ${accountBalanceOther.hbars}`);
}

```

## Step 4: Execution

This line calls the `main()` function to start the execution of the script.

```javascript
main();
```
