# Solana Sniper Bot (Poc)
|
|
This code is written as proof of concept to demonstrate how we can buy new tokens immediately after the liquidity pool is open for trading.
|
|
|
|
Script listens to new Raydium USDC or SOL pools and buys tokens for a fixed amount in USDC/SOL.
|
|
Depending on the speed of the RPC node, the purchase usually happens before the token is available on Raydium UI for swapping.
|
|
|
|
This is provided as is, for learning purposes.
|
|
|
|
## Setup
|
|
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 the configuration set below.
|
|
- Configure the script by updating `.env.copy` file (remove the .copy from the file name when done).
|
|
- Check [Configuration](#configuration) section bellow
|
|
- Install dependencies by typing: `npm install`
|
|
- Run the script by typing: `npm run start` in terminal
|
|
|
|
You should see the following output:
|
|
|

|
|
- `RPC_WEBSOCKET_ENDPOINT` - WebSocket RPC endpoint for real-time updates from the Solana network.

|
|
- `COMPUTE_UNIT_PRICE` - Compute price used to calculate fees.
|

- `PRE_LOAD_EXISTING_MARKETS` - Bot will load all existing markets in memory on start.
|
|
- This option should not be used with public RPC.
|
|
- `CACHE_NEW_MARKETS` - Set to `true` to cache new markets.

|
|
- `MAX_BUY_RETRIES` - Maximum number of retries for buying a token.
|
|
- `BUY_SLIPPAGE` - Slippage %
|
|

|
- `AUTO_SELL_DELAY` - Delay in milliseconds before auto-selling a token.
|
|
- `PRICE_CHECK_INTERVAL` - Interval in milliseconds for checking the take profit and stop loss conditions.
|
|

## Common issues
|
|
If you have an error which is not listed here, please create a new issue in this repository.
|
|
To collect more information on an issue, please change `LOG_LEVEL` to `debug`.
|
|
|
|
### 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:
