What is Solchat?

Could you please explain what Solchat is? I've heard it mentioned in the context of cryptocurrency and decentralized communication, but I'm not entirely sure what it entails. Is it a messaging platform specifically designed for users in the crypto space? How does it differ from other messaging apps, and what unique features does it offer? Additionally, is Solchat built on a blockchain or is it leveraging any specific blockchain technology? I'm intrigued by its potential applications and would appreciate a concise yet comprehensive explanation of what Solchat is and how it works.
