<header>Introduction</header>
<article class="main-article">
<p>Transactions are the core of the Stellar network. This tutorial will guide you through building and submitting a custom transaction using the Stellar SDK for JavaScript.</p>
</article>
</section>
<section class="main-section" id="prerequisites">
<header>Prerequisites</header>
<article class="main-article">
<p>Ensure you have:</p>
<ul>
<li>Node.js installed.</li>
<li>A text editor or IDE (like VSCode).</li>
<li>Basic knowledge of JavaScript.</li>
<li>A funded Stellar account (refer to the first tutorial).</li>
</ul>
</article>
</section>
<section class="main-section" id="step1">
<header>Step 1: Set Up the Project</header>
<article class="main-article">
<p>First, create a new project directory and install the Stellar SDK:</p>
<code>
mkdir stellar-custom-asset <br>
cd stellar-custom-asset<br>
npm init -y<br>
npm install stellar-sdk<br>
</code>
</article>
</section>
<section class="main-section" id="step2">
<header>Step 2: Load the Stellar SDK and Configure Accounts</header>
<article class="main-article">
<p>Create a file named buildTransaction.js and add the following code:</p>
<code>
const StellarSdk = require('stellar-sdk'); <br>
const server = new StellarSdk.Server('https://horizon-testnet.stellar.org'); <br>
<br>
// Source account keys <br>
const sourceKeys = StellarSdk.Keypair.fromSecret('SOURCE_SECRET_KEY'); <br>
<br>
// Destination account public key <br>
const destinationPublicKey = 'DESTINATION_PUBLIC_KEY'; <br>
<br>
// Transaction details <br>
const amount = '10'; // Amount of XLM to send <br>
const memoText = 'Test transaction'; <br>
</code>
<p>Replace SOURCE_SECRET_KEY with the secret key of your source account and DESTINATION_PUBLIC_KEY with the public key of your destination account.</p>
</article>
</section>
<section class="main-section" id="step3">
<header>Step 3: Build and Sign the Transaction</header>
<article class="main-article">
<p>Add the following code to build a transaction with a memo and a payment operation:</p>
<code>
async function buildAndSubmitTransaction() { <br>
try { <br>
const account = await server.loadAccount(sourceKeys.publicKey()); <br>
<br>
const transaction = new StellarSdk.TransactionBuilder(account, { <br>
fee: StellarSdk.BASE_FEE, <br>
networkPassphrase: StellarSdk.Networks.TESTNET, <br>
}) <br>
.addMemo(StellarSdk.Memo.text(memoText)) <br>
.addOperation(StellarSdk.Operation.payment({ <br>
destination: destinationPublicKey, <br>
asset: StellarSdk.Asset.native(), <br>
amount: amount, <br>
})) <br>
.setTimeout(30) <br>
.build(); <br>
<br>
transaction.sign(sourceKeys); <br>
<br>
const transactionResult = await server.submitTransaction(transaction); <br>
console.log('Transaction successful!', transactionResult); <br>
} <br>
catch (error) { <br>
console.error('Error!', error); <br>
} <br>
} <br>
<br>
buildAndSubmitTransaction(); <br>
</code>
<p>This script builds a transaction with a memo and a payment operation, signs it, and submits it to the Stellar test network.</p>
</article>
</section>
<section class="main-section" id="step4">
<header>Step 4: Run the Script</header>
<article class="main-article">
<p>Run the script using Node.js:</p>
<code>
node buildTransaction.js
</code>
<p>If successful, you'll see a message indicating the transaction was successful along with the transaction details.</p>
</article>
</section>
<section class="main-section" id="Conclusion">
<header>Conclusion</header>
<article class="main-article">
<p>You've successfully built and submitted a transaction on the Stellar network using the Stellar SDK for JavaScript. You can add more operations, adjust the memo, or interact with different accounts as needed. For more details on building transactions, check out the Stellar Transactions documentation.</p>
