Solana Pumpfun Sniper Bot

pumpfun sniper detects new token mints on the Pump.fun program, and automatically buys tokens whose market cap exceeds a configurable threshold.

Features

• Real-time monitoring of Pump.fun token mints via Geyser gRPC
• Automatic buy of new tokens above a market cap threshold
• Low-latency: avoids unnecessary RPC calls, uses pre-fetched data
• Configurable via environment variables

---

Requirements

• Go 1.18+
• Access to a Solana Geyser gRPC endpoint
• Helius or other Solana RPC endpoint (for sending transactions)
• Solana wallet private key (base58 string)

---

Environment Variables

Variable	Description
BUYER_PRIVATE_KEY_PATH	Your Solana wallet private key (base58 string, not a file path)
GRPC_ENDPOINT	Geyser gRPC endpoint URL
GRPC_AUTH_TOKEN	Authentication token for the gRPC endpoint
SOLANA_RPC_ENDPOINT	(Optional) Custom Solana RPC endpoint URL
HELIUS_API_KEY	(Optional) Helius API key (used if SOLANA_RPC_ENDPOINT is unset)

Setup & Build

1. Clone the repository

   git clone <your-repo-url>
   cd pumpfun-sniper-go

2. Install dependencies

   go mod tidy

3. Generate gRPC code from proto (if needed)

   protoc --go_out=. --go-grpc_out=. sniperc/sniperc/proto/geyserpb/geyser.proto

4. Build the bot

   go build -o pumpfun-sniper

---

Usage

1. Set environment variables (example for PowerShell):

   $env:BUYER_PRIVATE_KEY_PATH = "<your_base58_private_key>"
   $env:GRPC_ENDPOINT = "<your_geyser_grpc_endpoint>"
   $env:GRPC_AUTH_TOKEN = "<your_grpc_auth_token>"
   $env:HELIUS_API_KEY = "<your_helius_api_key>"  # or set SOLANA_RPC_ENDPOINT directly

2. Run the bot

   ./run

How it Works

• Subscribes to the bonkfun program on Solana via Geyser gRPC
• Monitors for new token mints
• Calculates the market cap using the initial SOL deposit and current SOL price
• If the market cap is above the threshold (default: $8,000), sends a buy transaction
• Uses a pre-fetched blockhash and SOL price for low-latency execution

---

Configuration

• Market cap threshold: Change MARKET_CAP_THRESHOLD_USD in main.go to adjust the buy threshold.
• Buy amount: Change BUY_AMOUNT_SOL in main.go to adjust how much SOL to spend per buy.

---

Security

• Never share your private key. Use a dedicated wallet for sniping.
• Review the code before running with real funds.
