Introducing PumpFun Sniper: First-Block Token Sniping on Solana

We're excited to announce the official launch of PumpFun Sniper - a high-performance Solana trading bot that detects and trades new PumpFun token launches in the first block.

If you've been missing profitable token launches or arriving too late to the party, PumpFun Sniper changes the game. It reads shreds, buys the new mint through AllenHark Relay and sells on a timer, so you are working from the block as it is built rather than from an RPC that reports it later.

🎯 What is PumpFun Sniper?

PumpFun Sniper is an automated trading bot that:

• Detects new token launches from shreds using AllenHark's ShredStream service
• Buys while the launch is still fresh, through AllenHark Relay
• Filters out scams and rug pulls with intelligent spam detection
• Tracks profitability and automatically blacklists unprofitable creators
• Runs 24/7 without manual intervention

Unlike traditional bots that rely on RPC polling, PumpFun Sniper taps directly into Solana's Turbine protocol via ShredStream, so it sees a launch before any RPC confirms it.

⚡ Key Features

First-Block Execution

See and trade tokens before they appear in confirmed blocks. While other bots are still waiting for RPC confirmation, you're already in.

Where detection happens:

• Traditional RPC bot: after confirmation, at the next poll
• PumpFun Sniper: from shreds, while the block is being produced

Smart Filtering

Not every token launch is worth sniping. PumpFun Sniper includes configurable filters to help you avoid:

• Spam tokens (micro-buys, malformed transactions)
• Rug pulls (suspicious dev buy patterns)
• Known scammers (automatic blacklisting)

Configure your filters based on:

• Developer initial buy amount (min/max SOL)
• Token supply and distribution
• Transaction structure
• Creator wallet history

Automatic Blacklisting

The bot learns from experience. When a creator launches a token that loses you money, they're automatically added to your blacklist. You'll never snipe their tokens again.

AllenHark Integration

PumpFun Sniper is optimized to work with AllenHark's infrastructure:

• ShredStream: shred data while the block is still being built
• AllenHark Relay: Optimized transaction submission straight to the leader's TPU over persistent QUIC connections
• QUIC Protocol: a persistent connection, no handshake per transaction

Don't have AllenHark services? The bot works with standard RPC providers too, though it then sees launches later.

🚀 Getting Started

Step 1: Download

Download the latest release for Linux (x86_64):

Download PumpFun Sniper v1.2.0

wget https://github.com/AllenHark-Inc/PumpFun-Sniper/releases/latest/download/sniperbot-linux-x86_64.tar.gz
tar -xzf sniperbot-linux-x86_64.tar.gz
cd sniperbot
chmod +x sniperbot

Step 2: Configure

Create a config.toml file with your settings:

# Trading Parameters
purchase_amount_sol = 0.001      # Start small while testing
slippage_basis_points = 100      # 1% slippage
live = false                     # Dry-run mode first!

# Your Wallet
payer_keypair_path = "./wallet.json"

# RPC Endpoints (add your API keys)
rpc_pool = [
    "https://mainnet.helius-rpc.com/?api-key=YOUR_KEY",
    "https://rpc.shyft.to?api_key=YOUR_KEY"
]

# Filters (adjust to your risk tolerance)
min_dev_buy_sol = 0.5
max_dev_buy_sol = 4.5

[spam_filter]
min_buy_sol = 0.01
max_buy_sol = 10.0

Step 3: Run

./sniperbot

The bot will start monitoring for new token launches and automatically execute trades based on your configuration.

📊 What to Expect

Realistic Performance

PumpFun Sniper puts you early, but it's not a money printer. Here's what to expect:

Detection: every PumpFun create that reaches you on the shred feed

Filter Pass Rate: most tokens fail the spam filters (this is good - most launches are scams)

Success Rate: depends on your region, your filters and the rest of the field; measure it in dry-run mode first

Profitability: Highly variable. Depends on market conditions, your filters, and exit strategy.

Usage Fees

The pre-built binary includes usage fees:

• 0.001 SOL before each buy
• 0.001 SOL after each sell
• Total: 0.002 SOL per trade cycle

Fees are charged regardless of trade profitability and are non-refundable.

Want to remove fees? The source licence has no usage fee and lets you customize the bot however you like; we quote it on request. Contact us on Discord.

🛡️ Risk Management

Start Small

Begin with purchase_amount_sol = 0.001 (minimum) and run in dry-run mode (live = false) to understand how the bot behaves.

Use Filters Wisely

Aggressive filters = fewer trades but higher quality Loose filters = more trades but more risk

Start conservative and adjust based on results.

Monitor Your Wallet

The bot will spend SOL on every token that passes your filters. Make sure you have sufficient balance and monitor regularly.

Download the Blacklist
