The price was a function of the mint number and nothing else: arithmetic written into the contract, which nobody could move. Machine #1 cost 27,000 FUEL, every mint after it cost 8 more, and the last one cost 53,656. Every token that arrived was burned on the spot, and that took 134,413,224 FUEL out of a one billion supply. The mint is over; this page is the record of it and the only place the contract address will ever come from.
Every machine stayed sealed until the mint closed. What was fixed at mint time is the machine itself; its character (habit, appetite, seam) came from a seed whose hash was published before the first mint and was revealed only after the last one, mixed with a block hash that was already written when the mint landed. Nobody could see it early, us included.
