After the initial release, no new Catto NFTs of existing topics will be released. To make more NFTs of existing topics, users will need to mint them using Catto NFTs they already have in their inventory. To unlock minting, users will need two NFTs of at least Level 6 with the same topic.
Two Catto of at least level 6 to unlock minting.
These two NFTs need to have the same topic.
Each Catto NFT can be used to mint new NFTs a maximum of 7 times. The cost to mint a new Catto NFT and the probability of a new Catto NFT having the same topic as the source NFT will increase the more times the existing Catto NFT is used for minting.

If the two source Catto NFTs have differing mint counts, the cost and probability of inheritance will be an average of the two. If the new Catto NFT does not inherit the source topic, a topic randomly drawn from the existing pool will be chosen.
When a new Catto NFT is minted, it will appear as a Catto Box, to be opened by the user or sold in the marketplace. Each Catto Box will have a tier attribute that is determined by the source Catto NFTs used to mint it.
