The amount of BAS paid to mint will be calculated along a curve where as more BAS is stored in the smart contract, the less BAS it will cost to mint. The logic here is that as the BAS gaming ecosystem grows, and more players join, more NFTs will be minted and held by players and more BAS will be locked within this smart contract, i.e. there will be high ‘TVL’ behind the NFTs. In order to compensate for the expected rise in BAS price due to more being bought and locked, it is necessary that the price of BAS decrease along with the increase in TVL, in order to keep the minting price stable and the game still accessible to everyone. Conversely, a decrease in TVL will result in an increase in BAS required to mint. The BAS received for disenchantment will be regulated with the same maths and all logic will be handled by smart contract (subject to multiple audits).
