# 8 : Use the native Stellar Lumens (XLM) the classic way.

## Token Playground Chapter 8 : Use the native Stellar Lumens (XLM) the classic way.

### 1. Introduction

What about when we want to use XLM inside a Soroban smart contract? How do we trigger those transactions? Can we trigger transactions on behalf the user using the `require_auth` method?

In this chapter we will start using XLM, asking for our balance the classic way (without Soroban). In the next chapter we will use Soroban!

### 2. Check your XLM's own balance using the classic way

Let's do our first experiment with the native XLM contract. We will create a new account, fund it with friendbot and check our balance in the classic way.

0.- Run the `quickstart.sh` script and enter into the soroban-preview container. Read chapter 1 and 2.

```bash
bash quickstart.sh
bash run.sh
```

1.- Create a new account:

```bash
soroban config identity generate my-account
MY_ACCOUNT_ADDRESS="$(soroban config identity address my-account)"
```

2.- Fund it with friendbot. Here I'll assume you are inside the soroban-preview containter

```bash
SOROBAN_RPC_HOST="http://stellar:8000"
FRIENDBOT_URL="$SOROBAN_RPC_HOST/friendbot"
curl  -X POST "$FRIENDBOT_URL?addr=$MY_ACCOUNT_ADDRESS"
```

3.- Check your balance with the classic way Using javascript and node, and assuming that MY\_ACCOUNT\_ADDRESS="GC6IYOXRAGMVSUDCAHBGBP2ZCAMZVNIF7CZCBY6545EQMIDNQQZCOY5G"

```javascript
var user_address="GC6IYOXRAGMVSUDCAHBGBP2ZCAMZVNIF7CZCBY6545EQMIDNQQZCOY5G"
var server = new StellarSdk.Server(settings.horizonUrl, {allowHttp: true});

server.loadAccount(user_address)
  .then(account => {
    // Find the XLM balance
    const xlmBalance = account.balances.find(balance => balance.asset_type === 'native');

    console.log(`Your XLM balance: ${xlmBalance.balance}`);
  })
  .catch(error => {
    console.error('Error loading account:', error);
  });
```

You'll get a result like this:

```bash
Your XLM balance: 10000.0000000
```

### 3. Use our code

If you want to use our **code** in the [Token Playground's Repo](https://github.com/esteblock/token-playground/), you can just call our script with the `soroban-preview-10` docker containter

You can run it by:

```bash
bash src/chapter8/use_XLM_native.sh 
```

Check all the code in the repo!

## What is next?

In this chapter we created a new Stellar account and we fund it with `10000` XLM and we managed to check it's balance in the classic way. In the next chapter we will check its balance using smart contracts in Soroban!

Are you ready?
