Solana shred streaming

What does a shred stream deliver?

Shreds carry pieces of Solana block data. A raw feed delivers those pieces to your receiver; your software handles decoding and the rest of its data pipeline. Observing a transaction in this data is different from proving its execution result or finality.

Lumios exposes the raw feed as ShredStream. This page describes that dashboard product; it does not imply access to a separate provider’s similarly named service.

Prepare the receiver before registration

The documented raw feed sends UDP datagrams to a public IPv4 address and port that you operate. Choose an enabled location and register the destination in Endpoints → ShredStream. Confirm traffic at the network and application layers before adding decoding.

Expect loss, duplicate packets, and reordering. Receive order is not a reliable transaction ordering rule. Keep packet handling small and measure socket drops, queue depth, and processing progress.

• Verify the destination and inbound network rules.
• Confirm the decoder understands the received shred format.
• Decide how to detect gaps and recover incomplete application state.
• Test bursts and reconnect or registration changes before depending on the feed.

Raw shreds or decoded transactions?

Choose raw shreds when you want to own the decoding pipeline. Pulse provides a separate decoded path over QUIC with signature-first and full-transaction modes. Yellowstone offers filtered subscriptions for backend data consumers.

Start with your output requirement: packet bytes, transaction messages, or filtered updates. Compare the operating cost of each consumer, not only its first-event timing. Available products and locations are shown for your selected access.
