Multicast & networking support: For detailed multicast or networking questions, contact colo-support@coinbase.com.
Test environment: Only instruments actively running on Starbase in the test environment have live market data. If you subscribe to a test channel for an instrument that is not yet active on Starbase, you will not receive any data.
Market data will only be sent by the active switch and duplicate data will not be received. The secondary connection will begin to receive market data during a failover scenario.

Cross-Connects & Non-Colocated Access

Cross-connects are available in LD4. Deribit is running a cable-length equalization process so that latency does not depend on a client’s rack placement within the data center. Contact colo-support@coinbase.com to arrange a cross-connect. Clients who are not colocated or cross-connected can still receive multicast market data over AWS via the Deribit AWS Multicast Service.

Feed Characteristics

  • Each gateway publishes market data from a single event-loop thread, so sequence numbers within a channel are strictly increasing and monotonic.
  • Updates are batched: a single UDP packet can contain multiple messages (see messageCount in the packet header).
  • This is a Level 3 (market-by-order) feed — every matching engine event that affects the book is reflected here, including an order that is added and then immediately removed, which still produces both the add (Buy Put/Sell Put) and the subsequent Order Delete message. There is no separate Level 2 (aggregated price-level) feed on Starbase.
