Vortex: High-Performance Solana Transaction & Relayer Engine

To eliminate latency bottlenecks and guarantee transaction delivery, I engineered Vortex—a bare-metal, high-performance transaction relayer built in Rust:

1. Validator Event Streaming via Geyser gRPC

Replaced standard HTTP JSON-RPC polling with real-time validator event streams via Geyser gRPC plugins. Vortex streams slot commitment status directly to lock-free

tokio::sync::mpsc

2. Dual-Send Submission with Jito MEV Bundles

Holds transaction payloads in memory and fires them simultaneously across primary Jito block engines and redundant RPC backup nodes precisely when validator submission windows open.

3. Dynamic Priority Tipping Engine

Terminal Workspace
// Autonomous Dynamic Tip Calculation & Priority Fee Allocation in Rust
pub async fn calculate_optimal_tip(congestion: &CongestionState) -> Result<u64> {
    let base_fee = congestion.median_priority_fee;
    let multiplier = match congestion.slot_utilization {
        u if u > 0.90 => 2.5,
        u if u > 0.75 => 1.5,
        _ => 1.1,
    };
    Ok((base_fee as f64 * multiplier) as u64)
}

4. Decoupled Open-Source Crate Architecture

Decoupled the core execution runtime into an open-source, production-ready Rust library published on Crates.io as
