That contract address belongs to a token called Blast, and it seems they have their own blockchain and make use of their own personal explorer.

Seriously, why are mods allowing these kinds of posts? i understand this place has become a place for jeets to try to make a $ or 2 by posting anything but come on, a guy got hacked, he doesn't need simpletons posting stupidities
i read a few of those tweets i linked.
apparently it seems it's a contract approval issue.
that email directed you to the phishing link you posted in your op (the fake galxe site), where you probably approved ETH on the arbitrum chain, probably for an infinite amount.
you're saying your eth also got stolen on blast but i'm guessing those are the same eth from arbitrum that you thought would be deposited to blast.
that's why you don't have to worry about your eth on any other chain or about any other asset in your wallet.
if you're willing to share your addy here or the tx that drained you, it would be easy to confirm. maybe that would ease your mind a little.
also you might wanna revoke that tx you approved with a tool such as revoke.cash. if you're not familiar with that kind of process, just say so, i'll guide you.
p.s :one last thing. when something like this happens to you, you're vulnerable and scammers know it... so i suggest that if anyone dms you to offer his help, you tell him to fuck off.
