modbender Solana Sniper Bot
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
- Pool Monitor — Watches Raydium AMM for new liquidity pool creation events
- 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
- LLM Risk Assessment — Sends token data to Claude Haiku for rugpull probability estimate
- Auto-Buy — If risk score < threshold, buys via Jupiter aggregator for best price
- Position Management — Monitors positions with take-profit and stop-loss triggers
- 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.
