Fellow Binancians,
To support sustained growth in WebSocket traffic and enhance overall stability and scalability, Binance Futures has upgraded its USDⓈ-M Futures WebSocket URL architecture.
The new structure separates traffic by data category — Public, Market, and Private — to provide clearer routing, improved connection management, and better operational isolation.
Key Highlights:
Introduction of three dedicated WebSocket base URLs:Public (high-frequency public market data)wss://fstream.binance.com/publicMarket (regular market data)wss://fstream.binance.com/marketPrivate (user data streams)wss://fstream.binance.com/privateBoth access modes remain supported:ws mode (path-based subscription)stream mode (?streams=; Private uses listenKey + events)Combined streams remain supportedPrivate supports listenKey + events subscription (multiple listenKeys and multiple events)New endpoints are supported immediately upon this announcement.Legacy WebSocket URLs will be permanently retired on 2026-04-23.
Example of New Method:
Public (ws mode)
wss://fstream.binance.com/public/ws/btcusdt@depth
Market (stream mode)
wss://fstream.binance.com/market/stream?streams=btcusdt@markPrice
Private (listenKey + events)
wss://fstream.binance.com/private/ws?listenKey=
