constant●k's 'Kaldera gRPC'

Powered by Yellowstone gRPC & Enhanced by Jito Shredstream

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 Jito Shredstream, each node pulling from the closest Jito location to itself. By piping the latest Solana shreds directly into our RPC, we bypass standard gossip network hops. You get market state updates milliseconds before they reach standard RPC nodes—giving you the ultimate first-mover advantage.

Zero-Latency Information

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.

Dedicated Lanes

constant●k's custom gRPC streaming proxy gives every subscriber their own dedicated, isolated stream from Yellowstone gRPC — no shared channels, no contention between users. Each connection gets a high-capacity message buffer with intelligent flow management: if your client falls behind during processing, the buffer absorbs the burst without dropping your connection or degrading service for anyone else. The result is a resilient gRPC experience where slow consumers never impact fast ones, and brief processing pauses don't cost you a reconnect.
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, constant●k requires no complex coding to get up and running. Just copy, paste, and trade.

Bypass Public Congestion

Public endpoints often time out during high-traffic events. By plugging into our private node you secure a reserved lane for your transactions, ensuring your swaps land when others are too slow or fail.
Pure Speed & Guaranteed Alpha

constant●k's 'ShredPrism gRPC'

The full Solana stream via gRPC

Zero-Hop Architecture

Stop waiting for the Turbine fanout. ShredPrism gRPC is constant●k's custom Jito Shredstream gRPC relayer. It connects you directly to the Jito block engine and top-tier validators, delivering transaction fragments (shreds) the instant they are generated by the active leader. By bypassing the standard Turbine propagation tree, you receive market-moving data milliseconds before it reaches traditional RPC nodes.

Guaranteed Delivery

Raw shreds propagate over UDP - fast but fragile. Dropped packets mean missed data with no recovery. ShredPrism delivers over gRPC which is over TCC, meaning reliable transport with automatic retransmission, stream ordering, and graceful reconnection. You get Turbine-grade speed without building your own packet loss recovery. Every shred arrives, every time.

Pre-Block Visibility

In arbitrage, seeing the state early is as good as winning. Our architecture streams shreds in real-time as the block is being built. This gives you a high-fidelity view of pool states and price impact before the full block is ever broadcast or replayed by the rest of the network.

Full Stream, Unmetered

ShredPrism delivers the complete Solana shred stream, every transaction, every slot, nothing filtered. Each subscription gets a single dedicated stream with no per-request metering or rate caps. You receive exactly what the validators see, and you never have to worry about hitting a ceiling.

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 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 corrently only compounds complexity and increases variability. constant●k is designed to make our customer's operations streamlined and efficient.
