CEX Connectors
Centralized exchange (CEX) connectors integrate into a centralized exchange's WebSocket API, enabling standardized order placement/cancellation and order book data fetching from the perspective of Hummingbot strategies. Each connector is customized for a particular exchange's idiosyncrasies to enable this level of standardization, so they may should ideally have a maintainer, whose role is to ensure consistent performance by fixing bugs, incorporating API updates, and other ongoing work.
CEX Connector Governance¶
Connectors may be added by community members via New Connector Proposals, which require a minimum HBOT balance to create.
Each quarter, the CEX Connector Poll allocates HBOT bounties toward the top CEX connectors and determines which connectors should be included in the codebase going forward.
See the Connector Pots tab in HBOT Tracker for the current allocations for each exchange.
CEX Connector Standards¶
The Notion templates below summarize the file and functionalities needed to build the latest spot and perpetual connectors standards and support V2 Strategies:
- Spot Connector v2.1 Notion Template: Use this template to build
spotconnectors that conform - Perp Connector v2.1 Notion Template: Use this template to build
