Not exactly IntrovertCat, but it will come in handy for everyone. I found out a couple of hours ago that you can get cashback on AtomicHub for secondary market purchases :)

I recommend to those who haven't put together a blend yet or are getting ready to make a big purchase: FarmersWorld, for example.

https://caittoken.io/account/cashback/
Sign up and get cashback (0.5% WAX) on all of your secondary market purchases. Cashback comes straight to the wallet, I have already checked several times :)

The only downside - AtomicHub interface will not show you purchase price ("Your Purchase Price"). But you can find the price in History - Sales, when you open NFT page (for example: https://wax.atomichub.io/explorer/asset/1099570167270 - History - Sales - ok, 133.96 WAX).

CAIT - a very old and strong project, maximum credibility, I am not ashamed to recommend them :)
Who is worried about security: Authentication is done via secure connection, and each action with the contract must be signed manually.
