Hi @Adamantios @dagacha ,
I encountered issues executing the scripts on my local system, which led to these adjustments.

Example error:

cd trader; poetry run python ../trades.py --creator 0x247F466F6deaC348F694725F5abd0aC6309125F5; cd ..
Traceback (most recent call last):
  File "../trades.py", line 36, in <module>
    from scripts.mech_events import get_mech_requests
  File "/home/ilad/labs/olas/trader-quickstart/scripts/mech_events.py", line 196, in <module>
    sender: str, event_cls: type[MechBaseEvent]
TypeError: 'type' object is not subscriptable

My System details:

• OS: Linux-Fedora
• Python 3.8.18
• Poetry: 1.8.4
• Poetry-Core Version: 1.9.1

Let me know if you need further context or clarification.
