Is mnt ERC-20?

I'm just a bit confused about mnt tokens. Could you possibly clarify whether mnt is an ERC-20 token? I've heard that ERC-20 is a standard for tokens issued on the Ethereum blockchain, but I'm not entirely sure if mnt falls into that category. It would be great if you could explain the characteristics of ERC-20 tokens and how mnt, if it is indeed ERC-20, fits into that framework. Also, it would be helpful to know if there are any specific benefits or drawbacks of mnt being ERC-20, in terms of its functionality and use cases within the crypto and finance world. Thank you for your assistance in clearing up this matter for me.
