Hey @Mr Web.3
Always cool to see some crypto usecases around Typeform.
So only, people, part of the whitelist should be able to submit the form? and only once? is that right?
The easiest is probably to do the filtering after the submissions, either on the CSV or on google spreadsheet.
But if you want to do this in real time as people answer the form I think we talked about this a few times here. keywords might be “unique” or “duplicate” to search in the community.
If I was implementing something like this, I would rely on Logic, and preload the emails/addresses of people part of the whitelist. The logic would verify if the answer to the question is part of the list if it is you can continue, if it’s not you can’t.
Once the form is submitted you can update the logic to remove the address from the list. So they can only submit once.
It might need some dev work to update the form via API but definitively doable!
