Let’s explore how data works on SOON Network. All data on SOON is stored in accounts - think of these as unique containers that can hold either data or program code. In this guide, we’ll learn to read and understand different types of accounts.

​
Read a Basic Account

First, let’s examine the simplest type of account - your own wallet. Open this example in Solana Playground: 
// Get your wallet's public key - this is your account's address
const address = pg.wallet.publicKey;

// Fetch the account's information from the network
const accountInfo = await pg.connection.getAccountInfo(address);

// Display the account's details
console.log("Your Wallet Account Info:");
console.log("======================");
console.log("Address:", address.toBase58());
console.log("Balance:", accountInfo.lamports / 1000000000, "SOL");
console.log("Owner:", accountInfo.owner.toBase58());
console.log("Executable:", accountInfo.executable);
console.log("Data length:", accountInfo.data.length);

// Set up a listener for account changes
console.log("\nWatching for balance changes...");
const subscriptionId = pg.connection.onAccountChange(
    address,
    (updatedInfo, context) => {
        console.log("\nBalance updated!");
        console.log("New balance:", updatedInfo.lamports / 1000000000, "SOL");
    }
);
When you run this code, you’ll see something like: 
Your Wallet Account Info:
======================
Address: ATxydRH5uT8xivYQGH7e6KgFNkPvEn7UKMmABtFpgNkz
Balance: 1 SOL
Owner: 11111111111111111111111111111111
Executable: false
Data length: 0
Understanding the output:
  • The Address is your unique identifier on SOON Network
  • Balance shows your holdings in SOL (1 SOL = 1,000,000,000 lamports)
  • Owner (all 1’s) is the System Program that manages basic accounts
  • Executable: false means this account stores data, not program code
  • Data length: 0 is normal - basic accounts only store SOL balances

​
Explore Token Accounts

Now let’s look at something more complex - token accounts. Open this example in Solana Playground: 
import { TOKEN_PROGRAM_ID } from '@solana/spl-token';

// First, let's examine the Token Program itself
console.log("Token Program Info:");
console.log("=================");
const tokenProgramInfo = await pg.connection.getAccountInfo(TOKEN_PROGRAM_ID);
console.log("Is executable:", tokenProgramInfo.executable);
console.log("Data length:", tokenProgramInfo.data.length);

// Now find all token accounts owned by your wallet
console.log("\nYour Token Accounts:");
console.log("==================");
const tokenAccounts = await pg.connection.getTokenAccountsByOwner(
    pg.wallet.publicKey,
    {
        programId: TOKEN_PROGRAM_ID,
    }
);

if (tokenAccounts.value.length === 0) {
    console.log("No token accounts found - try creating one first!");
} else {
    tokenAccounts.value.forEach((account, i) => {
        console.log(`\nToken Account ${i + 1}:`);
        console.log("Address:", account.pubkey.toBase58());
        console.log("Data size:", account.account.data.length);
    });
}
The output shows two important things: 
Token Program Info:
=================
Is executable: true
Data length: 133352

Your Token Accounts:
==================
No token accounts found - try creating one first!
Notice how the Token Program:
  • Is executable: true because it contains program code
  • Has a large data size (133352 bytes) storing its instructions
  • Your wallet starts with no token accounts - these get created when you start using tokens

​
Find Program Accounts

Want to see all accounts owned by a program? Open this example in Solana Playground: 
import { TOKEN_PROGRAM_ID } from '@solana/spl-token';
import { PublicKey } from '@solana/web3.js';

async function scanProgramAccounts(programId: PublicKey) {
    // Log which program we're scanning
    console.log(`Scanning accounts owned by program: ${programId.toString()}`);
    console.log("==========================================");
    
    // Find all accounts owned by this program
    const accounts = await pg.connection.getProgramAccounts(programId, {
        dataSlice: { offset: 0, length: 0 }, // Just get metadata for efficiency
        filters: []
    });
    
    // Display the results
    console.log(`Found ${accounts.length} accounts\n`);
    accounts.slice(0, 5).forEach((account, i) => {
        console.log(`Account ${i + 1}:`);
        console.log("Address:", account.pubkey.toBase58());
        console.log("Balance:", account.account.lamports / 1000000000, "SOL");
        console.log("Data length:", account.account.data.length);
        console.log("-------------------");
    });
}

// Look at Token Program accounts
await scanProgramAccounts(TOKEN_PROGRAM_ID);
This code shows you:
  • How many accounts a program owns
  • The first few accounts’ addresses
  • Their SOL balances and data sizes

​
Monitor Network Activity

Real-time monitoring is crucial for responsive applications. Try this example in Solana Playground: 
console.log("Starting transaction and account monitoring...");
console.log("============================================");

// Watch for account balance changes
const accountSub = pg.connection.onAccountChange(
    pg.wallet.publicKey,
    (accountInfo, context) => {
        console.log("\nAccount Updated!");
        console.log("New balance:", accountInfo.lamports / 1000000000, "SOL");
        console.log("Slot:", context.slot);
    }
);

// Watch for transaction confirmations
const signatureSub = pg.connection.onSignature(
    // Request an airdrop to see this in action
    await pg.connection.requestAirdrop(pg.wallet.publicKey, 1000000000),
    (signatureResult, context) => {
        console.log("\nTransaction Confirmed!");
        console.log("Signature:", signatureResult);
        console.log("Slot:", context.slot);
    }
);

console.log("Monitoring active - try requesting an airdrop to see updates!");
Run this code and you’ll see:
  • Real-time balance updates when your account changes
  • Transaction confirmations as they happen
  • Network slot numbers showing when events occur
Try requesting multiple airdrops while this runs to see how the monitoring works!
