I am surprised with the silence. WDC had devoted team for so long and they were active just until recently.
I think OP and the website need to be updated. Some of the exchanges delisted WDC while some other added, some links are death.
The most urgent issue is a very long block time, exceeding 5 hours now. The basic Worldcoin promise was short transaction time, wasn't it?
This could get fixed by either changing the algo from scrypt to something else or at least the difficulty adjustment.
Both require a hard or soft fork. This was already mentioned here (2 years ago): https://worldcoin.global/2358-2/

I believe the team will wake up. It would not be reasonable to abandon and waste long time efforts spent to maintain this project for them.
The blockchain age, the presence on the exchanges are worth of some extra work.
