RayStack

A fast, no-nonsense monitor for Pump.fun on Solana.

I built this because I needed a way to catch new token launches immediately without the lag you get from standard RPC polling. It connects directly to a Solana WebSocket, filters the logs for Pump.fun's "Create" instruction, and pipes the alerts straight to Discord.

It's written in Rust so it just runs in the background without eating up memory.

How it works

The logic is pretty simple: it's a producer-consumer setup. One part waits for the logs, passes them to a channel, and the other part processes them and handles the alerts.

graph TD
    subgraph Solana ["Solana Network"]
        RPC[("RPC Node")]:::sol
    end

    subgraph App ["RayStack Engine"]
        L["Listener"]:::comp
        B{{"Buffer"}}:::comp
        H["Handler"]:::comp
    end

    subgraph Out ["Output"]
        D["Discord"]:::dis
    end

    RPC == "Logs (WSS)" ==> L
    L -- "Filtered Events" --> B
    B -- "Async Data" --> H
    H -- "New Token Alert" --> D

Features

• Fast: Uses WSS logs subscription, so no polling delay.
• Specific: Only looks for the Create instruction on the Pump.fun program (6EF8...).
• Async: The listener never blocks. It dumps events into a buffer and keeps listening while the processor handles the Discord API calls.
• Resilient: If the socket drops, it just reconnects automatically.

Demo

Terminal Logs

Clean, human-readable logs showing accepted and rejected tokens.

Discord Alerts

Rich embeds with Ticker, Name, Dev Spend, and quick links.

Setup

1. Clone the repo.

2. Make a .env file:

   RPC_URL=wss://api.mainnet-beta.solana.com
   DISCORD_WEBHOOK=https://discord.com/api/webhooks/...

3. Run it:

   cargo run --release

That's it. It'll start printing logs when it finds new tokens.
