Solana Shred Stream Subscription Test Tool

This tool is used to receive Shred UDP data streams from a Solana node, automatically perform packet reconstruction (Reconstruct), missing data recovery (FEC Recovery), deshredding (Deshred), and transaction parsing, and supports subscribing to transaction events for specific accounts.

Key Features

• Real-time UDP Reception: Listens on a specified port to receive shred data from a Solana node.
• Automatic Reconstruction and Repair: Uses the Reed-Solomon algorithm to recover lost shreds.
• Deshredding and Parsing: Reassembles shreds into complete block entries and parses the transactions within.
• Account Subscription: Outputs only the transactions related to the specified account for precise monitoring.

Requirements

• Rust 1.80+ (latest stable version recommended)
• Tokio asynchronous runtime
• A fully synchronized Solana node (or network access to a Solana shred UDP stream)
• System dependencies:
