Multicast & networking support: For detailed multicast or networking questions, contact colo-support@coinbase.com.
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
messageCountin 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 subsequentOrder Deletemessage. There is no separate Level 2 (aggregated price-level) feed on Starbase. - Alongside order book events, the feed publishes derived and reference statistics: index prices via
IndexInfo(12), price bands and mark prices viaInstrumentInfo(14), and funding, settlement prices, and open interest viaInstrumentRef(15) — see Reference Data. Statistics not covered by these messages (for example, 24-hour volume) remain available from the standard Deribit JSON-RPC API (for example,public/tickerorpublic/get_book_summary_by_instrument).
Retransmit:
Each channel has its own retransmit port. The
Port column is the UDP unicast port used by colocation and cross-connect clients; the AWS Port column is the TCP port used by clients connecting over AWS Private Link. See Retransmit Gateway for the request protocol.
