Preconfs — faster Solana transaction data than shreds
Capture already-included transaction data inside the validator before raw shreds are emitted. Preconfs is a Binary add-on that merges pre-shred delivery with your existing Binary stream—same payload, earlier arrival for connected leaders.
- Binary add-on for qualified customers
- Same transaction data as Binary
- Typically 5–50 ms ahead of leader shreds
- Continuous stream: fastest source wins per transaction
- Safe for validators—transactions already included in the block
Preconfs require an active Shreder Binary subscription. They extend Binary—they do not replace it.

Preconfs are streamed only from connected current leaders. Coverage grows as more stake is connected. Read the launch article →
// What it is
Pre-shred data on top of Binary
On Solana, there is a gap between the moment transactions are executed and marked for inclusion and the moment the corresponding shreds are sent to the network. Raw shreds, Decoded Shreds, and Binary all depend on that emission step—so they cannot arrive earlier than the validator emits shreds, no matter how direct the network path is.
Preconfs shift the source earlier. Shreder captures transaction data inside connected leaders before shreds are emitted, then merges it into your Binary stream. Whichever source delivers a transaction first—earliest shreds or preconfs—gets sent straight to you.
- You keep your existing Binary integration and filters.
- You do not run additional validator infrastructure.
- Preconfs are optional—enable them when you need the extra edge.
Preconfs are a Binary add-on, not a standalone product. Start with Binary, then add Preconfs for qualified low-latency workloads.
Add-on layer
Pre-shred data from connected leaders, merged into the same stream.
One continuous feed
Every transaction, no gaps—fastest source wins per signature.
// Why Preconfs
Go beyond the shred emission boundary
For Binary users who have already optimized everything downstream and still need more.
Earlier than shreds
Capture data inside the validator before shredding and network transmission—cutting 5–50 ms off leader shred delivery for connected validators.
Seamless Binary add-on
No separate integration path. Preconfs merge into your existing Binary stream; same filters, same deserialization, same client code.
Network-safe design
Transactions are already included in the block before they are streamed. Preconfs do not expose pre-inclusion data or create block-influence opportunities.
Regional and leader-aware
Preconfs are local to your region and streamed only from current connected leaders—targeted acceleration where it matters.
// Performance
5–50 ms ahead of leader shreds
Shreder measured Preconfs against leader shreds from the same validators—not third-party providers.
Preconfs vs leader shreds
Expected lead over leader shreds
Measured across a number of validators; comparison is Preconfs vs shreds from the same leaders.
| Percentile | Preconfs lead | Leader shreds |
|---|---|---|
| P10 | 1–3 ms faster | Baseline |
| P50 | 5–10 ms faster | Baseline |
| P90 | 20–50 ms faster | Baseline |
// How it works
A continuous Binary stream with Preconfs layered in
Preconfs ship as a continuous stream on top of Binary: a mix of the fastest shreds and pre-shred data. Your client sees one uninterrupted feed—some transactions arrive from earliest shreds, some from preconfs.
- Requires an active Shreder Binary subscription.
- Streamed only from current connected leaders—not every transaction gets the boost.
- Regional: Frankfurt Preconfs cover transactions within meaningful distance from Frankfurt.
- Same transaction payload as Binary—no new deserialization step.
- Available to qualified Binary customers—contact us to discuss your use case.
Preconfs FAQ
What are Shreder Preconfs?
Preconfs are a Binary add-on that streams Solana transaction data captured inside the validator before the corresponding raw shreds are emitted. The payload matches Binary; delivery is faster for transactions from connected leaders.
Do I need Shreder Binary to use Preconfs?
Yes. Preconfs are provided as a continuous stream add-on on top of Shreder Binary. You subscribe to Binary first, then enable Preconfs for qualified use cases.
How much faster are Preconfs than leader shreds?
In Shreder testing against leader shreds from the same validators, expected leads are P10 1–3 ms, P50 5–10 ms, and P90 20–50 ms.
Is the Preconfs payload different from Binary?
No. Preconfs deliver the same transaction data as Binary. Some transactions arrive from the earliest shreds, some from preconfs—whichever source is first is sent to you.
Do Preconfs expose transactions before inclusion?
No. Transactions streamed via Preconfs are already included in the block by the time they are sent out. Preconfs do not expose transactions before inclusion decisions are made.
Which transactions get the Preconfs boost?
Only transactions from current leaders connected to Preconfs. Coverage grows as more stake and leaders are connected.
Which regions support Preconfs?
Preconfs launch in Frankfurt first. Streams are local to the region.
How do I get access to Preconfs?
Preconfs are available to qualified Shreder Binary customers. Contact the team to discuss your use case.
