🚀 Features

✔ Real-time transaction monitoring via Jito Shredstream
✔ Low-tip transaction detection (configurable threshold)
✔ Automated sniping with buy & sell strategies
✔ Redis caching for performance optimization
✔ Customizable parameters (price range, tip limits, delays)

⚙️ Setup

Prerequisites Rust (v1.70+ recommended)

Redis (for caching)

Solana CLI (optional, for wallet management)

Installation

Clone the repo:

git clone https://github.com/hodlwarden/jito-shredstream-pumpfun-sniper.git
cd jito-shredstream-pumpfun-sniper

Build the project:

cargo build --release

🔧 Configuration

Create a .env file in the root directory with the following variables:

# Jito Shredstream Endpoint (default: local Jito validator)
SERVER_URL="http://127.0.0.1:9999"

# Solana RPC (use a private RPC for lower latency)
RPC_URL="https://api.mainnet-beta.solana.com"

# Wallet Private Key (Base58)
PRIVATE_KEY="your_private_key_here"

# Redis Cache (improves performance)
REDIS_URL="redis://127.0.0.1:6379"

# Trading Parameters
MIN_SOL_PRICE="0.5"    # Min token price (SOL) to snipe
MAX_SOL_PRICE="3.0"    # Max token price (SOL) to snipe
BUY_SOL_AMOUNT="0.1"   # SOL amount per snipe
SELL_DELAY_MS="5000"    # Delay before selling (ms)
MAX_TIP_LAMPORTS="10000" # Max tip allowed (lamports)

🚀 Usage

Run the Sniper

cargo run --release

Custom Strategies

Modify src/utils/auto_trader.rs to adjust:

Buy conditions (e.g., liquidity thresholds)

Sell timing (dynamic delays, trailing stops)

Tip filtering (aggressive vs. conservative)

⚡ How It Works

Listens to Jito Shredstream for new transactions.

Detects low-tip transactions (below MAX_TIP_LAMPORTS).

Analyzes swaps for tokens in the configured price range (MIN_SOL_PRICE to MAX_SOL_PRICE).

Executes buys with BUY_SOL_AMOUNT.

Automatically sells after SELL_DELAY_MS.

📌 Notes & Warnings

⚠ High-risk trading: Sniping can lead to losses (slippage, rugs, failed TXs). ⚠ Use a dedicated wallet: Avoid using your main wallet. ⚠ Optimize RPC: A private RPC reduces latency (essential for sniping).

🔄 Advanced Optimizations

Run on a low-latency server (e.g., AWS/GCP in us-west-1).

Preload token metadata in Redis to speed up lookups.

Adjust gas fees dynamically based on network congestion.
