problem

I'm in your stack, touching your bits and playing with your stack and wrappers (fantastic work!!!)
However, to play with data I need to bridge to OP + create a smart margin account.

proposal

Enable user to instantiate with Kwenta(wallet_address=None, ...)
Handling sm_account to be None.

kwenta.py
ln 207: sm_account = self.get_sm_accounts()[0] if self.wallet_address else None

DoD

• user can interact with all queries and functionality that do not rely on an sm_account
