Sflowana

High-performance real-time Solana transaction and market-data engine written in Rust.

Sflowana ingests Solana activity, decodes protocol interactions, normalizes domain events, and streams structured data to latency-sensitive downstream systems.

It is designed as infrastructure for systems such as:

• Trading systems
• MEV/searcher infrastructure
• Market-data services
• Blockchain analytics
• Protocol monitoring
• Real-time Solana applications

Sflowana is not a trading bot, DEX, wallet, or trading strategy.

Its purpose is to provide the real-time data layer underneath those systems.

Architecture

The intended processing pipeline is:

Solana

   ▼
Ingestion
   │

Transaction Processing

Protocol Decoders
   │
   ▼
Event Normalization

   ├──────────────► Hot State

   ▼
Event Streaming

   ├── Trading
   ├── MEV
   ├── Analytics
   └── Monitoring

The initial implementation will start with Solana RPC-based ingestion and progressively introduce streaming sources, protocol-specific decoders, replay, and performance benchmarking.

Goals

Sflowana is being built to explore and demonstrate:

• Rust systems programming
• Async and concurrent architecture
• Solana transaction processing
• Protocol decoding
• Real-time event pipelines
• Low-latency networking
• Backpressure and bounded concurrency
• WebSocket streaming
• Deterministic replay
• Performance measurement

Non-Goals

Sflowana will not become a general-purpose:

• DEX
• Trading bot
• Wallet
• MEV strategy
• Block explorer
• RPC node
• Analytics dashboard

Those systems may consume Sflowana's output, but they are outside its core scope.

Development

Check the project:

cargo check

Run tests:

cargo test

Run formatting:

cargo fmt --all

Run linting:

cargo clippy --all-targets --all-features -- -D warnings

Run the application:

cargo run

Project Status

Sflowana is currently in the initial architecture and implementation stage.

The first milestone is a clean Solana ingestion and transaction-processing pipeline. Protocol-specific market-event decoding and real-time streaming will be introduced incrementally.
