API/programmatic traders can connect directly to the exchange server to improve latency and performance by whitelisting up to 15 IP addresses. 

The servers to connect through whitelisted addresses are as follows:

• https://api.futures.kraken.com/derivatives/api/v3 
• wss://api.futures.kraken.com/ws/v1 

Kraken Futures reserves the right to remove any IP addresses from the whitelist at any time and for any reason.

Note: this feature only applies to Kraken Futures API. IP whitelisting is not yet available for Kraken API.
