Solana Sniper Bot

Autonomous Solana token sniper and trading bot. Monitors new token launches on Raydium/Jupiter, evaluates rugpull risk with LLM analysis, auto-buys promising launches, and manages exit strategies. Use when user wants to snipe Solana token launches, trade memecoins, monitor new Solana pairs, or build a Solana trading bot. Supports cron-based monitoring, take-profit/stop-loss, and portfolio tracking.

Autonomous token sniper for Solana. Monitors Raydium and Jupiter for new liquidity pools, evaluates tokens using LLM-powered rugpull detection, and executes buy/sell orders via Jupiter aggregator.

Prerequisites

• Solana wallet with SOL for gas + trading capital (USDC or SOL)
• Anthropic API key (uses Haiku for token evaluation ~$0.001/eval)
• Helius or QuickNode RPC (free tier works, paid recommended for speed)

Setup

1. Install Dependencies

python3 {baseDir}/scripts/setup.sh

Or manually:

pip install solana solders httpx aiohttp python-dotenv

2. Configuration

Create .env:

SOLANA_PRIVATE_KEY=<base58-private-key>
LLM_API_KEY=<anthropic-api-key>
RPC_URL=https://api.mainnet-beta.solana.com
HELIUS_API_KEY=<optional-for-faster-monitoring>
BUY_AMOUNT_SOL=0.1
TAKE_PROFIT=2.0
STOP_LOSS=0.5

3. Deploy

cp {baseDir}/scripts/sniper.py /opt/sniper/
python3 /opt/sniper/sniper.py

How It Works

1. Pool Monitor — Watches Raydium AMM for new liquidity pool creation events
2. Token Analysis — For each new pool, queries token metadata:
   • Mint authority (revoked = good)
   • Freeze authority (revoked = good)
   • LP burned/locked percentage
   • Top holder concentration
   • Contract verification status
3. LLM Risk Assessment — Sends token data to Claude Haiku for rugpull probability estimate
4. Auto-Buy — If risk score < threshold, buys via Jupiter aggregator for best price
5. Position Management — Monitors positions with take-profit and stop-loss triggers
6. Auto-Sell — Exits via Jupiter when TP/SL hit

Risk Scoring

Each token gets scored 0-100 (lower = safer):

Factor	Weight	Red Flag
Mint authority	25%	Not revoked
Freeze authority	20%	Not revoked
LP lock	20%	< 80% locked
Top 10 holders	15%	> 50% supply
Contract age	10%	< 1 hour
LLM sentiment	10%	Negative assessment

Default buy threshold: risk score < 40

Trading Parameters

Configurable in .env:

• BUY_AMOUNT_SOL — Amount per snipe (default: 0.1 SOL)
• TAKE_PROFIT — Exit multiplier (default: 2.0 = 100% gain)
• STOP_LOSS — Exit multiplier (default: 0.5 = 50% loss)
• MAX_POSITIONS — Max concurrent positions (default: 5)
• MIN_LIQUIDITY — Minimum pool liquidity in USD (default: $5000)
• SLIPPAGE_BPS — Slippage tolerance in bps (default: 500 = 5%)

⚠️ Security Considerations

• Use a DEDICATED wallet with only what you're willing to lose
• Memecoin trading is extremely high risk — most new tokens go to zero
• Never use your main wallet's private key
• Start with tiny amounts (0.01-0.1 SOL per trade)
• Monitor actively — this is not a set-and-forget system
• RPC rate limits — Free Solana RPC will miss fast launches. Use Helius/QuickNode for serious sniping.
