Is the Mantle network live?

Excuse me, could you please clarify the status of the Mantle network? I've been hearing a lot about it recently and I'm quite interested in its potential. Is it currently operational and accessible to the public? Or is it still in the process of being developed and not yet ready for live use? It'd be great if you could provide some insight into its current status and any upcoming developments. Thank you in advance for your help.
