LaserSell is designed to get you up and running quickly. Instead of manually writing configuration files from scratch, the application includes an Interactive Setup Wizard that runs the first time you launch it.

​
1. Initial Setup (The Wizard)

After you have created or imported your wallet (see LaserSell Wallet), the wizard will automatically proceed to the Configuration phase. This interactive process configures your connectivity to the Solana network. You will be prompted for the following inputs in your terminal:

​
Step 1: License Activation

The first prompt asks for your license key.
  • Input: Paste your LaserSell license key here.
  • Note: The key is validated immediately. You cannot proceed without a valid license.

​
Step 2: RPC Connection

The wizard asks how you want to send transactions and fetch account data.
  • Use private RPC? [y/N]:
    • No (Default/Recommended): Uses Helius. You will be asked for your Helius API key later.
    • Yes: Select this if you have your own private node. You will be prompted to enter your HTTP/HTTPS URL.
  • Use public RPC?: (Only appears if you declined private RPC). We recommend choosing No to stick with Helius, as public RPCs are often too slow for sniping.

​
Step 3: Stream Connection

The wizard asks how you want to receive market data (new mints, price updates).
  • Use Laserstream? [y/N]:
    • Yes: Uses the proprietary low-latency Laserstream backend. This requires a Helius Pro Plan.
    • No: Uses standard WebSockets.
  • Stream Source: If you aren’t using Laserstream, you can choose to stream data via Helius (recommended), a Private Node, or Public nodes.

​
Step 4: Credentials

  • Helius API Key: If you selected Helius for RPC or Streaming, you must paste your API Key here.
  • Private URLs: If you selected Private modes, you will need to paste your RPC (HTTP) and WebSocket (WSS) URLs.
Once finished, the wizard saves a config.yml file and an encrypted keystore to your disk.

​
2. The Configuration File

While the wizard handles connectivity, it applies default safety settings for your trading strategy (e.g., Take Profit at 0.2 SOL, Stop Loss at 0.1 SOL). To customize your strategy, change slippage settings, or enable telemetry, you must edit the generated config.yml file. Open the file in your text editor: 
nano config.yml

​
Strategy Section (Important)

This controls when LaserSell exits a position. You likely want to change these defaults to match your risk profile. 
strategy:
  target_profit: 0.2        # or "50%"
  stop_loss: 0.1            # or "25%"
  sell_all_timeout_sec: 30
  • target_profit:
    • SOL Amount: Enter a number (e.g., 0.5) to sell when profit exceeds that amount in SOL.
    • Percentage: Enter a string (e.g., "100%") to sell when the position value doubles (2x).
  • stop_loss:
    • SOL Amount: Enter a number (e.g., 0.1) to sell if you lose that amount in SOL.
    • Percentage: Enter a string (e.g., "20%") to sell if the value drops 20% below your entry price.
  • sell_all_timeout_sec: A hard time limit. If a trade is still open after this many seconds, LaserSell will exit immediately to free up your capital.

​
Sell Execution

Controls the safety parameters for sell transactions. 
sell:
  slippage_pad_bps: 20      # Buffer added to calculated slippage (0.20%)
  slippage_max_bps: 2000    # Hard cap on slippage (20.00%)
  confirm_timeout_sec: 10   # How long to wait for confirmation
  max_retries: 2            # Retries if a sell fails

​
Telemetry

To use the Chrome Extension dashboard, ensure telemetry is enabled. 
telemetry:
  enabled: true

​
3. Applying Changes

If you edit the config.yml file while LaserSell is running, the changes will not take effect immediately. You must restart the application:
  1. Press Ctrl+C to stop LaserSell.
  2. Run lasersell again.
Your new settings will be loaded on startup.
