Hi this looks fantastic. I tried using myself but I am getting a runtime error that the metamask extension cannot be found. Running from VS - where are you executing the list.py file from? May thanks, Tom

@tommytoolman On line 14, you'll have to enter the relative route to your metamask.crx file. The current code as written will only work if the crx file is in the same directory as list.py

This is awesome! Does it still work? And have you tried running this from a cloud service?

hi, you help so much, but how to automatically set the date?
