Dynamic Minting Costs

Mint costs are dependant on the BNB/GRI exchange rate:

Min (BNB/GRI)	Max (BNB/GRI)	Mint GRI
0	80	≤1680 GRI
80	400	1,680 ~ 1,780 GRI
400	6,000	1,780 ~ 2,000 GRI
6,000	60,000	2,000 ~ 3,200 GRI
60,000	150,000	3,200 ~ 4,500 GRI
150,000	300,000	4,500 ~ 6,000 GRI
300,000	1,200,000	6,000 ~ 10,000 GRI
1,200,000	2,400,000	10,000 ~ 15,000 GRI
2,400,000	∞ .	20,000 GRI

Example, if 1 BNB = 50,000 GRI, this falls in the range of 6,000 ~ 60,000, and thus the current base mint cost would be 3,200GRI.

The first two mints costs the same and does not incur a “multiple minting penalty”, while subsequent mints will begin costing more due to this penalty. However, higher mint counts improve the chances of twin Shoebox drops, balancing the “risk” and “reward” of multiple mints on a single Sneaker.

Shoebox Quality is determined by the Parent Sneakers’ Quality:
