Raydium CPMM Trading Bot

Automated Solana trading bot that monitors new Raydium CPMM pools and executes buy/sell trades with configurable filters.

Features

• Real-time pool monitoring via Solana account subscriptions
• Smart filtering (LP value, pool age, token safety checks)
• Automated buy/sell execution with Bloxroute fast submission
• Auto WSOL wrapping/unwrapping
• Priority fee management

Quick Start

npm install && npm run build

Create .env:

RPC_ENDPOINT=https://api.mainnet-beta.solana.com
RPC_WEBSOCKET_ENDPOINT=wss://api.mainnet-beta.solana.com
PRIVATE_KEY=your_private_key_base58_or_json
BLOXROUTE_API_KEY=your_api_key
BLOXROUTE_API_URL=https://ny.solana.dex.blxrbdn.com
BUY_AMOUNT_SOL=0.0001
HOLD_TIME_SECONDS=30
MIN_LP_VALUE=30000
MAX_AGE_SECONDS=5

Run: npm start or npm run dev (with auto-reload)

Configuration

Variable	Description	Default
RPC_ENDPOINT	Solana RPC HTTP endpoint	Required
RPC_WEBSOCKET_ENDPOINT	WebSocket endpoint (optional)	-
PRIVATE_KEY	Wallet private key (base58 or JSON array)	Required
BLOXROUTE_API_KEY	Bloxroute API key (paid required)	Required
BLOXROUTE_API_URL	Bloxroute API URL	https://ny.solana.dex.blxrbdn.com
BUY_AMOUNT_SOL	SOL amount per buy	0.0001
HOLD_TIME_SECONDS	Hold time before sell	30
MIN_LP_VALUE	Minimum LP value (USD)	30000
MAX_AGE_SECONDS	Max pool age to consider "new"	5

Testing

npm run test                    # Mock data test
npm run test real <pool>         # Test with real pool
npm run test monitor            # Live monitoring test
npm run test buy-sell <pool>    # Full buy/sell test

How It Works

1. Detection: Subscribes to Raydium CPMM program account changes
2. Filtering: Validates pool age, LP value, and token safety (no mint/freeze authority)
3. Trading: Buys → waits → sells, with automatic WSOL handling and Bloxroute submission

Important Notes

Bloxroute: Paid API required. Bot sets minimum priority fee (1M microlamports = 0.001 SOL/1M CU). Ensure wallet has SOL for: buy amount + fees + priority (~0.001 SOL) + rent.

Token Safety: Automatically skips tokens with mint/freeze authority to prevent rug pulls.

Networks: Supports Mainnet, Devnet, Testnet (configure RPC endpoints accordingly).

Troubleshooting

Error	Solution
RPC_ENDPOINT is not set	Check .env exists
insufficient tips	Verify Bloxroute API key is valid (bot sets min fee automatically)
Pool does not contain SOL/WSOL	Bot only trades SOL/WSOL pairs - verify pool tokens
Transaction failures	Check wallet balance, pool validity, RPC responsiveness, API key
