"a cat that has helped many people"

mstrz, or better known as Pak Seku, I met him on a Telegram channel. He's the admin of the valuable and S.A.D channels. When I first met him, he was a friendly, funny, and very helpful admin, which matches the profile he always uses: a handsome cat. What I know is that he's also an Arbitrum ambassador and provides a lot of education about web3 or just talks about life problems.
