How to Get Lighter Credentials

  1. Visit Lighter DEX and create an account
  2. Navigate to your account settings
  3. Generate API keys from the dashboard
  4. Note down your:
    • accountIndex - Your Lighter account index
    • apiKeyIndex - The API key index
    • apiPublicKey - Your API public key
    • apiPrivateKey - Your API private key
After importing credentials, you can use the standard trading endpoints to place orders on Lighter without providing credentials as query parameters.
If you don’t have existing Lighter credentials, you can generate them directly on the Lighter platform and then import them using this endpoint.
