Account Switch

You can change your Account Type (tied to your L1 address) using the /changeAccountTier endpoint.

You may call that endpoint if:

You have no open positions
You have no open orders
At least 3 hours have passed since the last call

Python snippet to switch tiers:

# You can get the values from the system_setup.py script

# ACCOUNT_INDEX =
# API_KEY_INDEX =


async def main():
    client = lighter.SignerClient(

        private_key=API_KEY_PRIVATE_KEY,
        account_index=ACCOUNT_INDEX,
        api_key_index=API_KEY_INDEX,
    )

    err = client.check_client()
    if err is not None:
        print(f"CheckClient error: {err}")
        return

    auth, err = client.create_auth_token_with_expiry(
        lighter.SignerClient.DEFAULT_10_MIN_AUTH_EXPIRY
    )

    response = requests.post(

        print(f"Error: {response.text}")
        return
    print(response.json())

How fees are collected:

In isolated margin, fees are taken from the isolated position itself, but if needed, we automatically transfer from cross margin to keep the position healthy. In cross margin, fees are always deducted directly from the available cross balance.

Sub-accounts share the same tier as the main L1 address on the account. You’ll be able to switch to a Premium Account now. Let us know if you have any questions.
