# Create subaccount

The subaccount creation process follows the below steps.

1. The main account must authorize the creation of a subaccount under its control
2. The subaccount must consent to being controlled by the main account
3. The API server must verify both signatures to prevent unauthorized subaccount creation<br>

Valid addresses must be used in order to establish main/subaccount relationships via API:

* Neither account can be a subaccount of another account.
* The subaccount address cannot have any deposit/trade history

Please refer to the [Python SDK](https://github.com/pacifica-fi/python-sdk/blob/f2385d42e9ae5276ba2ba85505d51db2eefd2715/rest/create_subaccount.py) for a comprehensive guide on subaccount creation via API
