Ethereum: Binance Futures ACCOUNT_UPDATE Transmits Transactions via WebSockets

As a developer building applications on the Ethereum blockchain, you are probably familiar with working with web sockets and interacting with exchange APIs. However, when it comes to streaming trading using Binance Futures, things can get a little more complex. In this article, we will address the issue of getting a response from the Binance API for a streaming transaction “ACCOUNT_UPDATE” via websocket.

Problem: No response

Let’s assume you have successfully configured your WebSocket connection to Binance and are trying to execute a streaming transaction “ACCOUNT_UPDATE”. You use the following code:

import json
import websocket

Set up the WebSocket connection
socket = 'wss://fstream.binance.com/ws'

Define the API endpoint for ACCOUNT_UPDATE streams
stream_endpoint = "Olympus"

Create a new WebSocket object
ws = websocket.create_connection(socket)

Send an UPDATE request to the stream endpoint
msg = {
"jsonrpc": "2.0",
"method": "ETH_getAccountUpdate",
"params": ["0x..."], 
Replace with your account address
"id": 1
}
ws.send(json.dumps(msg))

Wait for a response
while true:
try:

Receive JSON data from the server
data = ws.recv()
if "result" in data and data ["result"] == "ok":
print(data)
elif 'error' in data and data['error']['code'] == 1000: 
account update error
print('Account update error:', data['error']['message'])
else:
break
except websocket.exceptions.ConnectionClosed:
break

Close the WebSocket connection
ws.close()

As you can see, this code sends an UPDATE request to the ETH_getAccountUpdate endpoint with your account address as a parameter. However, it doesn’t seem to receive any response from the server.

Possible causes:

• Invalid API endpoint: Make sure you are using the correct API endpoint for the ACCOUNT_UPDATE (Olympus) flows and that the endpoint is formatted correctly.

• Missing Authentication

  : Binance requires authentication when making API requests. Make sure to add your account credentials to the jsonrpc header with the following format:

{"jsonrpc": "2.0", "method": "ETH_getAccountUpdate", "auth": {"address": "0x..."}, "id": 1}

• Timeout or Connection Issues: If you are experiencing a timeout or connection issue, try increasing the timeout parameter in your WebSocket request:

ws = websocket.create_connection(socket, timeout=30)

• Server Errors

  : There may be server errors that cause the API to not return any response. Please check Binance documentation for any known issues or updates related to ACCOUNT_UPDATE streams.

Example Use Cases:

• Testing Stream Trading: You can use this code as a starting point to test stream trading with Binance Futures.

• Development and Debugging: This example demonstrates how to send an UPDATE request to the ETH_getAccountUpdate endpoint for testing purposes.

Conclusion:

In conclusion, when it comes to stream trading on Binance using websockets, getting a response from the server can be a challenge. Make sure to configure the API endpoint and authentication credentials correctly. Additionally, be aware of potential issues such as timeouts, connection issues, or server errors. With some troubleshooting, you should be able to resolve this issue and successfully receive responses from Binance for stream trading purposes.
