# Send Solana via javascript functions

### **Step 1: Init JavaScript Project** <a href="#id-4de5" id="id-4de5"></a>

```
npm init
```

### **Step 2: Install modules** <a href="#id-5270" id="id-5270"></a>

```
npm install -S @solana/web3.js bs58
```

@solana/web3.js — Solana JavaScript SDK\
bs58 — encoding library

### **Step 3: Create JavaScript script file** <a href="#id-8e9a" id="id-8e9a"></a>

You can use any text editor. Create an empty file with .js extension.\
\&#xNAN;*For e.g: **test.js***

### Step 4: Include installed modules <a href="#id-9de3" id="id-9de3"></a>

At the beginning of created file we will include required modules:

```
const web3 = require('@solana/web3.js');
const bs58 = require('bs58');
```

### Step 5: Init connection and create Keypair object <a href="#id-4bcf" id="id-4bcf"></a>

```
const connection = new web3.Connection('https://api.mainnet-beta.solana.com', 'confirmed');

const privateKey = bs58.decode('619G6W.....XaWz4');
const from = web3.Keypair.fromSecretKey(privateKey)
```

As an argument for **web3.Connection** method we will use any Solana RPC.\
\&#xNAN;*For e.g default mainnet RPC:* [*https://api.mainnet-beta.solana.com*](https://api.mainnet-beta.solana.com/)

In constant **privateKey** we will load wallet private key (you can find it in the settings of your wallet)

We will save Keypair object to constant **from**.

### Step 6: Create Trasnaction <a href="#c2b4" id="c2b4"></a>

```
(async () => {
    const transaction = new web3.Transaction().add(
        web3.SystemProgram.transfer({
          fromPubkey: from.publicKey,
          toPubkey: '9aq15...NzYHSJdxMa5t',
          lamports: 900000
        }),
      );
    
      const signature = await web3.sendAndConfirmTransaction(
        connection,
        transaction,
        [from],
      );
      
      console.log('SIGNATURE', signature);
})()
```

At the second string we create **transaction** constant. We will pass to **web3.Transaction().add()** method result of calling **web3.SystemProgram.transfer()** method with following arguments:

* fromPubkey — publicKey property of Keypair object
* toPubkey — string with SOL address to where we want to send SOL (lamports)
* lamports — amount of lamports that we want to send
* **fromPubkey** also may be a string\
  \* **toPubkey** also may be a Keypair object (in this case we will use **publicKey** property)\
  \* lamports is a piece of SOL. We can use this [converter](https://www.solconverter.com/) for better understanding

**signature** constant contains a result of execution **web3.sendAndConfirmTransaction()** method where we passed **connection** constant, **transaction** data and sender **Keypair** object.

Expected output of following code is a transaction hash:

```
SIGNATURE MifLinkmkV.....wEjnDxi25Gcb4HfoU9DM7dfLoCyw3U6tmpznczMivTj
```
