Why constant-k?
Constantly Striving
We Run Our Own Metal
constant-k Solana RPC services are hosted on servers we build and maintain. We've spent countless hours experimenting, tuning and optimizing our nodes to be as fast and reliable as possible. Many RPC providers white label hardware from big box datacenters so you never really know where your data is going. When you use constant-k, you can be assured your transactions are interacting only with hardware that we physically control. Our fleet lives in New York, Frankfurt and Amsterdam, so your traffic hits a low-latency Solana RPC endpoint on whichever side of the Atlantic you trade from.
99.99% Network Uptime
We operate with a goal of 99.99% uptime and do our best to alert users before any downtime. Our network stack is optimized from the ground up for continual high-load operation, including through power outages. We treat your apps and trading activity as mission critical operations. Service terms are outlined in our Terms of Service document.
Affordability & Simplicity
constant-k services are priced and designed for active developers and traders who know the difference between profit and losing money often comes down to milliseconds. We built these nodes by learning what traders need. Worrying about monthly transaction credits or if your transaction is getting routed correctly only compounds complexity and increases variability. constant-k is designed to make our customer's operations streamlined and efficient.
