Binance has announced an upgrade to the USD-M (U-based) Futures WebSocket URL architecture to support traffic growth and enhance overall stability and scalability.
🆕 What's New — 3 Specialized Base URLs
The new architecture is divided into three specialized base URLs by data category:
Public — High-frequency public market data
Market — Regular market data
Private — User data stream
📅 Key Dates
The new WebSocket URL is available for use starting now, and the old URL will be permanently decommissioned on April 23, 2026.
✅ What's Still Supported
This upgrade continues to support both ws and stream access modes as well as combined subscriptions.
⚡ Earlier Ping/Pong Changes (Feb 2025)
WebSocket services now send a ping frame every 20 seconds (previously 3 minutes), with the allowed pong delay reduced to 1 minute (previously 10 minutes).
📌 Pro Tip for Devs
It is highly recommended to get order status, position, and account info from the WebSocket user data stream rather than REST endpoints, especially during volatile market conditions.
Bottom line: If you're using Binance Futures WebSocket, migrate to the new URLs now — the old ones go offline April 23, 2026. 🚨
