I've been wondering why it's called whirwind but I can't figure out where you got it from.

Why the site interface is similar to the mixing service from @whierwindmoney, the similarity is almost close to matching.
I thought I was the only one who noticed it
Especially the side of the statistics where there is anonymity set

Maybe they got some inspiration from tornado.cash
Neither this whirlwind got inspiration from tornado cash nor the maker from the tornado cash family But both are great

The only difference is that tornado is (air-based phenomenon) while whirlwind is (earth-based phenomenon)

Also the extension tornado.
cash while whirlwind.
money

I don’t know if using the current service is worth the risk knowing how this project was already under the watch of the government.
There is no guarantee that any future version will be run by the government or that there will be development of the project.
