solana-pumpfunx-sniper-bot

A high-performance sniper bot written in Rust that observes PumpFun and PumpSwap on Solana and submits trades with very low latency. It uses transaction monitoring to identify trading opportunities and execute orders promptly, helping you act within short windows.

The bot specifically tracks buy and create transactions on PumpFun and recognizes token migration events from PumpFun to Raydium.

Setting up

Environment Variables

Before running, add the following variables to your .env file:

• GRPC_ENDPOINT - Your Yellowstone gRPC endpoint URL.
• GRPC_X_TOKEN - Leave as None if the endpoint does not require a token for authentication.
• GRPC_SERVER_ENDPOINT - Address for the gRPC server (default: 0.0.0.0:50051).

Run Command

RUSTFLAGS="-C target-cpu=native" RUST_LOG=info cargo run --release --bin shredstream-decoder

Solana Sniper Bot

A Rust-based sniper bot that monitors transactions and submits trades with very low latency on PumpFun, PumpSwap, and Raydium.

Features

• Sub‑second Execution - Sub-second transaction submission using optimized RPC calls and direct transaction building.
• Low-latency Transaction Monitoring - Uses Yellowstone gRPC for transaction data with minimal delay and high reliability.
• Multi-address Support - Monitor multiple wallet addresses at the same time.
• Protocol Compatibility - Works with PumpFun, PumpSwap, and Raydium to increase coverage.
• Automated Trading - Executes buy and sell transactions automatically when configured conditions are met.
• Notification System - Sends trade alerts and status updates via Telegram.
• Customizable Parameters - Configure limits, timing, sizes, and other trading settings.
• Built-in Selling Strategy - Includes configurable profit-taking and exit rules.
• Whale Detection - Algorithms to spot and follow large wallet activity.
• MEV Protection - Built-in measures to reduce exposure to MEV risks.
• Account Management - Automatic token account creation and routine maintenance.
• SOL ↔ WSOL Utilities - Wrapping and unwrapping helpers for WSOL conversions.
• Caching Layer - Smart caching to lower RPC usage and speed up responses.
• Transaction Retry Logic - Structured retries for transient failures.
• Performance Optimizations - Async processing with tokio for high-throughput handling.
• Error Recovery - Automatic reconnection and retry behavior to maintain operation.
• Fee Optimization - Adaptive fee handling to help control transaction costs.

Project Structure

• engine/ - Core sniper bot logic (trading flows, selling strategies, parsing, retries).
• dex/ - Protocol-specific code for PumpFun, PumpSwap, and Raydium.
• common/ - Shared utilities: configuration, constants, caching, and logging.
• core/ - Token and transaction core functionality.
• services/ - External integrations (RPC clients, cache maintenance, Zeroslot).
• error/ - Error types and handling code.

Setup

Environment Variables

Required

• GRPC_ENDPOINT - Yellowstone gRPC endpoint URL
• GRPC_X_TOKEN - Yellowstone authentication token (or None)
• COPY_TRADING_TARGET_ADDRESS - Wallet address(es) to follow (comma-separated)

Telegram Notifications

• TELEGRAM_BOT_TOKEN - Telegram bot token
• TELEGRAM_CHAT_ID - Chat ID for notifications

Optional

• IS_MULTI_COPY_TRADING - true to monitor multiple addresses (default: false)
• PROTOCOL_PREFERENCE - pumpfun, pumpswap, or auto
• COUNTER_LIMIT - Max number of trades to execute

Usage

# Build the project
cargo build --release

# Run the bot
cargo run --release

# Additional commands:
# Wrap SOL to WSOL
cargo run --release -- --wrap

# Unwrap WSOL to SOL
cargo run --release -- --unwrap

# Close all token accounts
cargo run --release -- --close

When the bot runs it will:

1. Connect to the Yellowstone gRPC endpoint.
2. Monitor transactions for the configured wallet address(es).
3. Execute buy and sell transactions when rules are met.
4. Send Telegram notifications for detected events and executed trades.
5. Manage token accounts and WSOL conversions automatically.
6. Detect large transactions and significant wallet movements.
7. Submit transactions with minimal latency to pursue configured outcomes.
