Account Switch

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

You may call that endpoint if at least 24 hours have passed since the last call. To upgrade account type, there is no cooldown.

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.
