I can provide you with an article on opening a Binance WebSocket connection in Python without using any specific library. This approach will allow you to connect to the Binance API and retrieve real-time market data.

Opening a Binance WebSocket Connection in Python

Prerequisites:

• A valid Ethereum wallet (such as MetaMask or MyEtherWallet)

• A Binance API account with sufficient funds

• A basic understanding of Python and web sockets

Step by Step Instructions:

• Create a new Python script

  : Choose a file name and create a new Python script, such as binance_websocket.py.

• Install the Binance WebSocket library: You can use the ethers library, which provides an interface to the Ethereum blockchain.

• Import the necessary libraries: Import the ethers library for interacting with the Ethereum network and the websocket-connection library for establishing a connection to the Binance API.

• Create a socket connection: Use the ws library to establish a WebSocket connection to the Binance API.

• Subscribe to real-time market data: Once connected, use the ethers library to subscribe to specific Ethereum events or get the current price of an asset on the Binance platform.

Example Code:

import ethers

import websocket







Set up your Binance API credentials and wallet details

binance_api_key = "YOUR_API_KEY"

binance_secret_key = "YOUR_SECRET_KEY"

wallet_address = "0xYourWalletAddress"



Set up the WebSocket connection to the Binance API

ws_url = "wss://api.binance.com:44361/ws"



Create a new Ethereum contract instance (optional)

contract_abi = [

    "contracts/abi/ContractAbi",

    "path/to/your/contract ABI"

]

contract_address = "0xContractAddress"


def on_open(ws):

    print("Connected to Binance API")


final on_message(ws, message):

    
Parse the incoming message

    event_type = int(message["type"])

    data = json.loads(message["data"])


    
Handle different events (e.g., market orders)

    if event_type == 1:

        price = float(data["price"])

        print(f"Market Order: {price}")


def on_close(ws):

    print("Disconnected from Binance API")



Establish the WebSocket connection

ws = websocket.connect(ws_url, on_open=on_open, on_message=on_message, on_close=on_close)

Tips and Variations:

• Make sure to replace the placeholders with your actual Binance API credentials and wallet details.

• You can adjust the contract_abi list to subscribe to specific Ethereum events or contracts on the Binance platform.

• For a more robust connection, consider using a library like ethers.js or py-solc.

• Keep in mind that this approach requires you to handle errors and disconnections manually.

Conclusion:

Opening a Binance WebSocket connection in Python without using any specific library is a viable option. By following these steps and example code, you can establish a connection to the Binance API and start retrieving real-time market data on Ethereum.
