Revoke permission questions Revoke.Cash

I know how to use revoke.cash but I have questions, like who runs it? How is it run? Or who created it?

I don’t like the wording of this next one bc I don’t want to sound like a doubter but how can I trust it? I know the smart contracts I’ve signed so I know my risk on that end but I’d like to understand if revoke.cash carrys any risk?

I have used it previously in an old wallet but I did not understand how/why use a smart contract to revoke another? Is there any other way? I also have to ask how are they funded? I don’t see an organization name but I found an article on Medium and it mentions Gircoin Grants so I like hearing that part, they have/had funding so that adds legitimacy. I don’t want to sound like a doubter, I just wish to understand.

When searching about this I also found mention of it being part of that ledger fiasco, idk if that affected all wallets but that’s settled so should be no issue. I guess that’s said and done. Seeing a warning label made me slightly nervous for a sec lol

Im looking to revoke on eth avax and matic so if anybody can help with even some of these questions I’d might shed light on the rest

As always no Dms
