NFT 'lands' collection, divided among several planets that will be released little by little along with development of the game. Each planet has a fixed supply of lands of various types (common, rare, epic, legendary).

Mint / Land sale Each new planet can be minted in several rounds, planned as follow :

a whitelist round, limited in time, during which users need to provide a signature provided by our server, with a reduced price and a limited supply. The number of mint per planet a user can do is contained in the signature.
a public round, during which anyone can mint within a certain limit (3 per type of land)

All rounds combined, the number of minted land cannot exceed the total supply for the planet.

Reveal Each planet can be later 'revealed' by the owner, effectively changing the metadata of each of its land to reveal its detailed characteristics :

Before the reveal, all lands of a same type from the planet have the same attributes and medias
After reveal, our server will generate each token's attribute, store them in a folder on IPFS and provide the reveal CID to the smart contract for this planet
