sendTransaction

Installation

npm install @karrotcapital/spiderswap

Usage

Initialization

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

import Spiderswap from '@karrotcapital/spiderswap';
// OR
const Spiderswap = require('@karrotcapital/spiderswap');

const spiderswap = new Spiderswap(ApiKey);

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.

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.
