Constantly Striving

Why constant•k?

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.

99.99% Network Uptime

We guarantee 99.99% uptime or the pro-rated downtime costs will be refunded to you, inline with industry standards. Our custom network stack is optimized from the ground up for continual high-load operation in the event of power outages. Our dedicated fiber internet connection functions even without local power. We treat your apps and trading activity as mission critical operations.

Affordability & Simplicity

constant●k services are priced and designed for active developers and traders who know the difference between profitability and losing money often comes down to cents and getting the project done. We built these tools because we use them. We know that worrying about monthly transaction credits or which node location to use only compounds complexity and increases stress. constant●k is designed to make our customer's operations streamlined and efficient.
