❔Is it possible to bind an exchange to a bot via a sub-account?

Yes, you can trade via a sub-account. The process of connecting API keys for a sub-account is completely the same as the procedure of creating keys for the main account.

The main thing to take into account is that the keys must be created within the sub-account and for its use. Otherwise, the connection process is similar. After setting up, make sure that the bot correctly displays the balance of available funds corresponding to those you have transferred to the sub-account.
