# sendTransaction

## Installation

```bash
npm install @karrotcapital/spiderswap
```

## Usage

### Initialization

First, initialize the **`'Spiderswap'`** class with your API key.

<pre class="language-javascript"><code class="lang-javascript">import Spiderswap from '@karrotcapital/spiderswap';
// OR
const Spiderswap = require('@karrotcapital/spiderswap');

<strong>const spiderswap = new Spiderswap(ApiKey);
</strong></code></pre>

### Method: sendTransaction

**Description**

The **`'sendTransaction'`** method sends a Solana transaction to the blockchain, handling retries and confirmation.

**Parameters**

* **`'rpcEndpoint'`** (string): The RPC endpoint to send the transaction to.
* **`'transaction'`** (VersionedTransaction): The transaction object to be sent.
* **`'privateKey'`** (string): The private key of the sender, encoded in base58.
* **`'additionalSigners'`** (Array\<string> | null, default null): The additional signers that need to sign the transaction for it to be sent.
* **`'retries'`** (number, default 3): The amount of retries this function will try to do to execute the transaction.

#### Returns

**`'Promise<string>'`**: A promise that resolves to the transaction signature.

#### Example

This example demonstrates how to use **`'getSwap'`**, **`'createTransaction'`**, and **`'sendTransaction'`** methods.

```javascript
async function performSwapCreateAndSendTransaction() {
    try {
        // Get the swap data
        const swapResult = await spiderswap.swap.getSwap(
            'ownerAddress',
            'fromMintAddress',
            'toMintAddress',
            1,        // Amount in tokens
            0.5,      // Slippage percentage
            'provider',
            'pool',
            9         // fromMintDecimals
        );
        console.log('Swap data:', swapResult);
        
        const { base64Transaction, signers } = swapResult;

        // Create the transaction
        const transaction = await spiderswap.swap.createTransaction(base64Transaction);
        console.log('Transaction:', transaction);

        // Send the transaction
        const signature = await spiderswap.swap.sendTransaction(
            'https://api.mainnet-beta.solana.com',
            transaction,
            'privateKeyInBase58',
            signers,
            3
        );
        console.log('Transaction signature:', signature);
    } catch (error) {
        console.error('Error performing swap, creating and sending transaction:', error);
    }
}

performSwapCreateAndSendTransaction();

```

**Implementation Details**

This method attempts to send the transaction multiple times, updating the blockhash and signing the transaction each time. If it fails after a set number of retries, it throws an error.
