I can provide you with an article on how to open 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)

• Binance API account with sufficient funds

• Basic knowledge of Python and network 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 to interact with the Ethereum network and the « websocket-connection » library to connect 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 the asset on the Binance platform.

Sample Code:

import ether
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 WebSocket connection to 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"
definition on_open(ws):
print("Connected to Binance API")
definition on_message(ws, message):

Parse incoming messages
event_type = int(message["type"])
data = json.loads(message["data"])

Handle various events (e.g. market orders)
if event_type == 1:
price = float(data["price"])
print(f"Market order: {price}")
definition on_close(ws):
print("Disconnected from Binance API")

Establish a WebSocket connection
ws = websocket.connect(ws_url, on_open=on opening, on_message=on sending, on_close=on closing)

Tips and variations:

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

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

• For a more stable connection, consider using a library such as ethers.js or py-solc.

• Note that this approach requires manual error handling and disconnections.

Application:

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