Solana Sniper Bot

This code is written as proof of concept for demonstrating how we can buy new tokens immediately after liquidity pool is created.

Script listens to new raydium USDC/SOL pools and buys token for a fixed amount in USDC/SOL.
Depending on speed of RPC node, the purchase usually happens before token is available on Raydium UI for swapping.

Setup

In order to run the script you need to:

• Create a new empty Solana wallet
• Transfer some SOL to it.
• Convert some SOL to USDC or WSOL.
  • You need USDC or WSOL depending on configuration set below.
• Configure the script by updating .env.copy file (remove the .copy from the file name when done).
  • PRIVATE_KEY (your wallet private key)
  • RPC_ENDPOINT (https RPC endpoint)
  • RPC_WEBSOCKET_ENDPOINT (websocket RPC endpoint)
  • QUOTE_MINT (which pools to snipe, USDC or WSOL)
  • QUOTE_AMOUNT (amount used to buy each new token)
  • COMMITMENT_LEVEL
• Install dependencies by typing: npm install
• Run the script by typing: npm run buy in terminal

You should see the following output:

Common issues

If you have an error which is not listed here, please create a new issue in this repository.

Unsupported RPC node

• If you see following error in your log file:
  Error: 410 Gone: {"jsonrpc":"2.0","error":{"code": 410, "message":"The RPC call or parameters have been disabled."}, "id": "986f3599-b2b7-47c4-b951-074c19842bad" }
  it means your RPC node doesn't support methods needed to execute script.
  • FIX: Change your RPC node. You can use Helius or Quicknode.

No token account

• If you see following error in your log file:
  Error: No SOL token account found in wallet:
  it means that wallet you provided doesn't have USDC/WSOL token account.
  • FIX: Go to dex and swap some SOL to USDC/WSOL. For example when you swap sol to wsol you should see it in wallet as shown below:
