The tab design
The tab design on the upper right corner might lead to potential confusion. Say, a user clicked 'activity' is likely to be in "Searching" mode, not "Explore" mode. He might have a specific activity to look for.
I think I got a message that I can vote now. Where is that message? Damn I forgot which DAO it is about, I had to find it in the Activities
Therefore, he will be confused if the Activity tab is not all-inclusive, that he might be in the "Transaction" tab instead of the "Token" tab, therefore, didn't see the event.
On the other hand, the categorisation requires prior knowledge - the user needs to know the difference between "Transaction" and "Token" activity.
On top of that, sometimes an activity item is both a Token activity and a Transaction (typical example: purchase of a kitty).
Suggestion: we borrow the INBOX concept, that you might have a lot of different email folders, but you only have 1 INBOX. Remove the tab design and a few years later, if needed, add filter function or tagging for those who have too many stuff in INBOX and wants to look at specific activities.
INBOX != notification
My 2nd suggestion is based on this of your draft:
There I think we mixed notification in the activities. These items are activity items:
- Your ticket is redeemable/available now.
- Your ticket has expired (not redeemed).
These items are notification items:
- Your ticket is going to expire in 20 minutes.
- Last time to redeem your ticket.
The difference is like event notification and calendar entry. If you agree with this approach, kindly provide an activity vs notification picture in your draft.
