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.
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.copyfile (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 buyin terminal
You should see the following output:
If you have an error which is not listed here, please create a new issue in this repository.
- 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.
- 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:
