Turn milliseconds into PnL

Our Shred Delivery system is designed to get you raw shreds fastest anywhere in the world, including common locations like FRA, AMS, TYO, EWR, and more. During setup we validate path quality and ensure we're delivering raw shreds from servers closest to you.

Solana blocks are divided into small data packets known as shreds. These shreds are approximately 1.2 KB in size and contain Solana transaction data that is propagated across the network before being assembled into a full block. There are two types of shreds: data shreds, which contain the core transaction data from a block, and coding shreds, which provide parity data for redundancy using Reed-Solomon erasure coding.

To convert raw Solana shreds into actionable trading signals, shreds are reassembled by first verifying their signatures for authenticity. Next, Reed-Solomon erasure coding is used to reconstruct missing or corrupt data shreds from the coding shreds in the FEC set. Then, the verified, reconstructed shreds are deshredded. Deshredding is the process of concatenating shred payloads in order using shred indices to reform serialized entry batches. These batches are then deserialized into individual transactions and entries. Traders can then compare these entries to Solana’s latest available state to predict which transactions succeed, the resulting account/state changes, and determine if there is a trade to be made.

Both LaserStream and Shred Delivery are fed with low latency shreds. Shred Delivery is for teams that want raw, unprocessed shreds and can ingest UDP, deshred packets, and parse everything themselves. LaserStream is for teams that want processed, confirmed, and finalized on-chain events delivered with ultra-low latency and automatic recovery for backend paths where correctness matters.

Use Shred Delivery when you need the absolute lowest latency access to raw transaction data and have the technical capability to process raw shreds. Use LaserStream when you need reliable, processed data with commitment guarantees and historical replay capabilities. If speed is less critical for your application, use Enhanced Websockets or standard Solana WebSockets. If you need a simple, pull-based option, use webhooks.

You canpurchase Shreds from your Helius dashboard. Simply add a seat and set your IP address and port number to start receiving shreds. For more information, read our Raw Shreds documentation.
