Bolt IoT Innovation Challeng

I have just started my Bolt Iot journey. I want to ask that we have to make a project on hackster.io for the certification test. Can I submit the same project for the Bolt IoT Innovation Challenge or I have to create 2 different ones ?

For the Bolt IoT Innovation challwnge it is mandatory to submit the video along with the project?

yes you can submit any project which is integrated with Bolt IoT device
I think video is not mandatory
