Is voxel free to use?

Excuse me, could you please clarify if the use of voxel is indeed free of charge? I understand that there are various cryptocurrencies and platforms available, each with their own set of rules and regulations, and I'm interested in knowing if voxel operates under a similar model where users can freely utilize its services without incurring any costs. If there are any specific conditions or limitations to be aware of, I would greatly appreciate if you could elaborate on those as well. Thank you for your time and assistance.
