Ethereum Classic Transaction Broadcast with Node.js

This documentation provides a guide to broadcast Ethereum Classic transactions to the mainnet using a Node.js script and the CryptoAPIs service.

Requirements

• Node.js installed on your machine
• Axios' library for making HTTP requests

Setup

1. Install the required package by running:

   npm install axios
   

2. Obtain an API Key from CryptoAPIs:

   • Sign up for cryptoapis.io
   • Create a new api-key here

Script

Create a new file called broadcastETCTransaction.js and add the following script:

import axios from 'axios';

// Replace with your API key
const apiKey = 'your-api-key-here';

// Replace with your signed transaction hex
const signedTransactionHex = 'your-signed-transaction-hex-here';

const broadcastTransaction = async () => {
  try {
    const response = await axios.post(
      'https://rest.cryptoapis.io/blockchain-tools/ethereum-classic/mainnet/transactions/broadcast?context=broadcastETC',
      {
        context: '', // Optional
        data: {
          item: {
            signedTransactionHex: signedTransactionHex
          }
        }
      },
      {
        headers: {
          'x-api-key': apiKey,
          'Content-Type': 'application/json'
        }
      }
    );

    console.log('Transaction Broadcasted Successfully:', response.data);
  } catch (error) {
    console.error('Error broadcasting transaction:', error.response ? error.response.data : error.message);
  }
};

broadcastTransaction();

Running the script

1. Replace the apiKey and signedTransactionHex variables with your actual API key and signed transaction hex.
2. Run the script:

node broadcastETCTransaction.js

Response

If successful, the script will output a JSON object with the following structure:

{
  "apiVersion": "string",
  "requestId": "string",
  "context": "string",
  "data": {
    "item": {
      "transactionId": "string"
    }
  }
}

The response will contain the following fields:

• apiVersion (string): The version of the API.

• requestId (string): The ID of the request.

• context (string): The context of the response.

• data (object):

  • item (object):

    • transactionId (string): The ID of the broadcasted transaction.
