Pure Speed & Alpha

ShredPrism gRPC

Leader-Direct Liquidity Streams

Stop waiting for the gossip layer. ShredPrism connects you directly to the block producers, delivering transaction fragments (shreds) the instant they are generated by the active leader. Bypassing standard propagation delays, you receive market-moving data milliseconds before it hits traditional RPC nodes.

Pre-Block Visibility

In arbitrage, seeing the future is as good as winning. Our architecture streams partial block data as it is being built, giving you a comprehensive view of pool states and price impact before the block is fully finalized and broadcast to the rest of the network.

Zero-Hop Architecture

We’ve eliminated the network hops that kill alpha. By maintaining direct, persistent connections to the validator set, ShredPrism reduces jitter and ensures your strategy reacts to the "true" state of the chain, not a buffered echo.
Adaptable to Any Trading Style

High-Performance Across Every Interface

Whether you're trading on Jupiter, Raydium, or using a wallet like Phantom or Solflare, constant●k integrates seamlessly. Our service provides a standard RPC endpoint that instantly upgrades your trading environment.

Universal Compatibility

Designed to work natively with any dApp, bot, or wallet that accepts a custom RPC URL. No complex coding required—just copy, paste, and trade.

Bypass Public Congestion

Public endpoints often time out during high-traffic events. By plugging our private node into your DEX settings, you secure a reserved lane for your transactions, ensuring your swaps land when others fail.
Filtered Data, Turbocharged

Kaldera gRPC: Powered by ShredQuasar

See the Block Before It Propagates

Standard gRPC is fast, but constant●k's Kaldera gRPC is faster. Our architecture combines Triton’s Yellowstone Geyser plugin with ShredQuasar, our exclusive data ingestion engine. By piping the latest shreds directly into our RPC, we bypass standard gossip network hops. The result? You get market state updates milliseconds before they reach standard RPC nodes—giving you the ultimate first-mover advantage.

Zero-Latency Execution

In the world of Flash Loans and MEV, milliseconds mean margins. Kaldera gRPC streams account updates directly from our RPC's memory the instant a shred is replayed. Whether you are sniping liquidity or executing complex arbitrage, you are trading on the absolute latest state of the chain.

Precision Filtering

Don't drink from the firehose; aim it. Filter your shred-enhanced stream by specific accounts, programs (Raydium, Orca, Pump.fun), or transaction types. Get only the data you need, delivered faster than the competition can index it.

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.
