Here's a link to their polygonscan ....
They have announced new contract addresses
here.
Also please suggest a way to remove these tokens from my metamask and alternative security checks.
Use
this method to remove token from metamask. And it should be noted, this method only excludes this token from appearing in the metamask. If you view your address in explorer or import your address to another wallet, minereum will still be visible. Minereum tokens are not actually removed from your wallet until you send them to another address.
