exchanges-wrapper

Crypto exchanges API/WSS wrapper with grpc powered server

Binance, Bitfinex, Huobi, OKX, Bybit,

For SPOT markets

On Binance: now API key type Ed25519 is used instead of HMAC

From 2.1.34 must be updated exch_srv_cfg.toml from exchanges_wrapper/exch_srv_cfg.toml.template

exchanges-wrapper vs binance.py

The main difference is the development of the project for trading with many exchanges.

Next is adding a new module exchanges_wrapper/exch_srv.py as a multiplexer layer, providing simultaneous async interaction for many accounts and many trading pairs through one connection. It's powered by gRPC Remote Procedure Call framework.

Warning. Coverage of overridden binance.py packages is significant but not complete. Served methods describes into example/exch_client.py

Initial capabilities (inherited from binance.py)

• Covers general endpoints (test connectivity and get exchange information's)
• Covers market data endpoints
• Covers Account endpoints (create and manage orders)
• Covers user data stream (receive real time user updates)
• Covers web socket streams (receive real time market updates)
• Async support
• Auto reconnect after exchanges API or network failure
• Completely free and without limitations

Added Features

• Multi exchanges support
• Adaptive algorithm to ensure maximum performance and avoid exceeding the rates limits
• Passthrough logging
• WSS keepalive
• Reuse session for new client connections
• Utilizing Websocket API (bidirectional) for the most commonly used methods:

Extra exchanges implementation features

• Binance REST API and WSS are accepted as basic, connection of other exchanges wrapped their API to Binance compatible
• For other, some data cannot be obtained by directly calling one method, it is generated by a synthetic or calculation method
• Some exchanges have not any testing or "paper trading" features, therefore, application development and testing is possible only at real bidding. First, run applications on the Binance Spot Test Network or (Bitfinex, OKX, Bybit) test account.
