ShredStream Decoded
Decoded raw shreds delivered via the standard Yellowstone gRPC interface. Coming in v1.1.
// updated 2026-06-04
Status: coming soon. ShredStream Decoded is on the v1.1 roadmap and is not part of v1.0.
ShredStream Decoded (also known as aRPC) wraps raw Solana shreds in the standard Yellowstone gRPC protocol, so you get shred-level latency with familiar gRPC tooling.
What it is
Raw shreds give you Solana data faster than RPC or gRPC, but processing UDP packets directly is awkward. ShredStream Decoded removes that friction:
- Supanode receives shreds at the network edge (Shred Caster on XDP).
- Supanode decodes them into transaction-level events.
- Supanode exposes the events through the standard Yellowstone gRPC stream.
You get the latency advantage of ShredStream Raw with the integration simplicity of gRPC.
When should you use ShredStream Decoded vs ShredStream Raw vs gRPC?
| You need... | Use this |
|---|---|
| Lowest possible latency, raw UDP, you handle decoding | ShredStream Raw |
| Lower latency than gRPC, but standard gRPC integration | ShredStream Decoded |
| Standard real-time streams (most cases) | gRPC |
Available today: for shred-level latency right now, use ShredStream Raw (UDP, Frankfurt). For standard streaming with rich filters, use gRPC.
Pricing
Pricing is in finalization. Will land alongside the v1.1 release.
