"Mstrz"

He is a kind, friendly, and protective person. I know him through the SAD private channel. There, he is an admin with the nickname 'SAD Security,' which sounds fitting for him because his charisma and authority make the group's atmosphere conducive. He often chats not only with me but with all the members there, making him feel very approachable. He is also an active ambassador of Arbitrum, and I think that's very cool. He also often gives good advice on working on web3 projects or how to become an ambassador and even manage an X account, which I think is useful knowledge.
