Shredstream Overview

Shredstream pushes raw Solana mainnet shreds to a UDP destination that you control. It enters the data path before validator execution, so it does not behave like RPC, WebSocket, or Yellowstone gRPC.

An active Ultra plan includes 1 account-wide Shredstream destination, and Enterprise includes 2.

UltraShreds sells destinations on their own for $100 a month each, on any plan including Free. Purchased units stack on top of whatever the plan already includes, so an Ultra account with two UltraShreds units runs three destinations. An account may run five destinations in total — that is the per-customer limit of the delivery service, not a billing decision. Capacity beyond five is arranged through support.

UltraShreds is billed on its own Stripe subscription. A past-due or cancelled RPC plan does not stop delivery you are separately paying for; only cancelling UltraShreds itself, or an account-wide billing hold, does.

NoLimitNodes can also grant destinations directly — for a trial, a contractual commitment, or a goodwill credit. A granted destination behaves exactly like a purchased one and may carry an expiry date, which the dashboard shows alongside your unit count.

Delivery model

You register one account-wide destination per unit of capacity:

PUBLIC_IPV4_OR_ASSIGNED_10.250.0.x:UDP_PORT

NoLimitNodes sends a one-time verification challenge to the registered UDP socket. Delivery starts only after you paste that challenge into the node details screen. Each destination is verified independently. Removing one stops delivery to that address and frees the slot for another.

What you receive

• Solana mainnet data and coding shreds
• A wire format compatible with the Jito proxy and client path
• Raw packets that your receiver must deshred into entries

What you must operate

Your receiver must handle duplicate packets, out-of-order arrival, incomplete shred sets, forks, decoding, and backpressure. Use Yellowstone gRPC when you need filters, account updates, logs, execution status, or commitment.

Access and permissions

Account owners and workspace administrators can create, verify, replace, or remove the destination from any active node's details screen. Other workspace members can view its status. The destination belongs to the account, not the individual node used to open the control.
