ShredPrism — Solana Shred Stream over gRPC
ShredPrism is constant-k's Solana shred streaming service: the raw leader shred feed delivered over reliable gRPC from bare-metal nodes in New York and Frankfurt. It is the earliest look at Solana data we can physically give you — transactions as the leader publishes them, before the block has finished propagating.
Why Stream Shreds over gRPC?
Pre-Block Visibility
Solana transactions pass through five stages: submitted, packed, reassembled, executed, committed. ShredPrism hands you the stream while the block is still being built — in arbitrage and MEV, seeing state early is as good as winning.
Guaranteed Delivery — No UDP Roulette
Raw shredstreams propagate over UDP: fast, but a dropped packet is simply gone, and you find out when your strategy misfires. ShredPrism delivers over gRPC on HTTP/2 with TLS — ordered, acknowledged, retransmitted. The speed of shreds without silent data loss.
The Full Stream, Unmetered
Every transaction, every slot, nothing filtered. Each subscription gets a dedicated, isolated stream — up to 10 concurrent streams at 100 Mbps on Nexus. No per-request metering and no ceilings to plan around: you receive exactly what the validators see.
Zero-Hop, Enhanced by Raiden
Stop waiting for the Turbine fanout. ShredPrism connects you directly to our shred sources, and our partnership with Raiden — one of the fastest shred feeds on Solana — pushes delivery earlier still.
The Managed ShredStream Alternative
Running shred infrastructure yourself means deploying a relayer, managing UDP plumbing and writing reassembly code — all on your latency budget. ShredPrism is one authenticated gRPC connection: we run the infrastructure, you consume the stream.
ShredPrism is available on the Nexus plan, with endpoints in both New York and Frankfurt; your connection details and API key are provisioned in My Account after subscribing. Compare plans on the pricing page, see stream caps on plan limits, and watch our nodes' live latency on the benchmarks page. Want decoded, filterable account and transaction updates instead of raw shreds? That is Kaldera.
