How to buy tools in Alien Worlds?

I'm a bit of a novice in the Alien Worlds universe, so I'm wondering: how do I purchase tools in this fascinating crypto-powered metaverse? I've heard that these tools can enhance my mining and exploration experiences, but I'm not quite sure where to start. Do I need to use a specific cryptocurrency? Are there specific marketplaces or exchanges I should be looking at? And are there any tips or tricks you could share to ensure I get the best value for my purchase? Any guidance you can provide would be greatly appreciated.
