Starbase API Overview

Starbase is Deribit’s high-performance matching engine designed for institutional trading and market makers. Equipped with a Simple Binary Encoding (SBE) API, Starbase provides direct access to the matching engine with ultra-low latency, making it ideal for high-frequency trading applications.

At a later date, a FIX Drop Copy for a holistic view of orders and trades across the whole account will be added. A REST API with utility endpoints such as an order purge or order snapshot will also be added.

The main components of the Starbase API:

Binary Order Entry API

The Binary Order Entry API provides direct access to the matching engine using a high-performance binary protocol optimized for ultra-low latency trading.

• Order Entry: Place, amend, and cancel orders with minimal latency. Supports single orders, mass quotes (up to 15 double-sided quotes), and mass cancellation.
• Market Maker Protection (MMP): Built-in protection against adverse selection. See Market Maker Protection for details.
• Self Match Prevention (SMP): A highly flexible system to avoid matching order internally.

Multicast Market Data

Market data is distributed via multicast channels organized by product type (BTC perpetuals/futures, BTC options, ETH perpetuals/futures, ETH options, etc.). The multicast channels have:

• Market-by-order data: Market data is sent as L3 data, allowing for full reconstruction of the order book.
• A/B Redundancy: Duplicate feeds (A and B) for high availability.
• Snapshot and Incremental Updates: Snapshot feeds provide the full order book state, while incremental feeds provide real-time updates.
