Pushing Transactions to the Bitcoin Cash Network: A Guide

As the second-largest cryptocurrency by market capitalization, Ethereum has become a hub for decentralized applications (dApps) and smart contracts. However, not all of these dApps can interact with the Bitcoin Cash (BCH) network, which is gaining popularity as an alternative to Bitcoin. In this article, we’ll explore how to push transactions from Ethereum to the Bitcoin Cash Network using the Blocktrail API.

Why Use Blocktrail?

Blocktrail is a popular platform for tracking and managing distributed data applications, including those on the Ethereum blockchain. With their APIs, developers can integrate their dApps with various networks, including Binance Smart Chain (BSC) and BCH. In this case, we’ll focus on BSC, as it’s one of the most promising alternative cryptocurrencies to Bitcoin.

The Blocktrail API

Blocktrail offers a robust set of APIs that enable developers to interact with their blockchain applications. The blocktrail.com/api endpoint provides access to various data feeds, including transaction tracking and data analytics. To push transactions from Ethereum to BSC using the Blocktrail API, you’ll need:

• A valid Blocktrail account

• The bcsdk (Binance Smart Chain) wallet address or an Ethereum wallet with a compatible private key

• The blocktrail.com/api/v2/transactions endpoint

Step-by-Step Guide

Here’s a step-by-step guide to pushing transactions from Ethereum to BSC using the Blocktrail API:

• Get your BCSDK wallet address: If you’re using an Ethereum wallet, create a new account or connect an existing one to retrieve your private key.

• Generate a public-private key pair: Create a new private key (private_bytes) and corresponding public key (public_key). You can use tools like Jaintools or generate them manually with the ecdsa library in Python.

• Import the necessary libraries

  : Install the required libraries using pip: pip install blocktrail for Python

• Set up your Blocktrail API credentials: Create an account on Blocktrail.com and obtain your API token, client ID, and secret key.

• Connect to BCSDK wallet address or Ethereum wallet: Use the bcsdk_wallet library (if using BSC) or the eth library (for Ethereum) to connect to your private key and get the corresponding Ethereum address.

• Create a new transaction: Using the blocktrail.com/api/v2/transactions endpoint, create a new transaction with the desired inputs and outputs for your dApp. You can use a library like hashlib to generate hash functions.

• Push the transaction to BCSDK wallet address or Ethereum wallet: Send the created transaction using the Blocktrail API’s pushTransaction method, passing in your private key (public_bytes) as well as the Ethereum address of the recipient wallet.

Sample Code

Here’s an example code snippet in Python demonstrating how to push a transaction from Ethereum to BSC:

«`python

import json

from blocktrail import Customer

Blocktrail API credentials

blocktrail_token = «YOUR_API_TOKEN»

client_id = «YOUR_CLIENT_ID»

secret_key = «YOUR_SECRET_KEY»

Connect to BCSDK wallet address or Ethereum wallet

bcsdk_wallet_address = «0xYour_BCSDK_Wallet_Address»

ethereum_wallet_address = «0xYour_EthereumWallet_Address»

Create a new private key (private_bytes)

private_bytes = bcsdk_wallet_address.encode()

Generate public key (public_key) using the private key

public_key = ethereum_wallet_address.encode()

Create a new transaction

transaction_inputs = [

{«amount»: 10, «from»: «Ethereum Wallet Address», «to»: bcsdk_wallet_address},

]

transaction_outputs = []

transaction_hash_function = hashlib.sha256

Push the transaction to Blocktrail API

blocktrail_client = Client(blocktrail_token, client_id, secret_key)

push_transaction_result = blocktrail_client.
