Solana RPC Services for Devs & Traders

constant●k Solana RPC services are member-only so you're always at the front of the line. Your trades execute before others when compared to public RPC endpoints, which can become congested during high network traffic. A private RPC node is critical for time-sensitive operations like arbitrage or rapid trade execution.

Quicker transactions mean you can set your slippage and network fees lower. Trades with constant●k have a higher chance of success meaning more of the profit ends up in your wallet.

Our RPC systems are professionally tuned to reliably send out your trades as fast as possible. An advanced all-fiber multi-peering internet connection gets your trade to the validator leader quicker, ensuring you're not wasting money on slow and unprofitable transactions.

constant●k's unmetered Yellowstone Geyser service capitalizes on gRPC’s HTTP/2-based streaming and binary serialization delivering data faster than JSON-RPC or WebSocket, giving arbitrage bots a critical edge in fast-moving markets.

Yellowstone Geyser gRPC’s real-time data is ideal for flash loan strategies, where traders borrow funds, execute arbitrage trades, and repay the loan within a single transaction. By streaming data on token prices and pool states, traders can identify profitable opportunities.

Filter streams by specific accounts, programs (e.g., Raydium, Orca), or transaction types, reducing noise and focusing on critical market data for faster arbitrage decisions.

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.

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.

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.
