The project states supply, time window, bid limits and settlement rules before the round opens.
Participants choose a maximum price and requested quantity within the published limits.
Price tiers are ranked. The tier where available supply is exhausted sets the clearing price.
Accepted units share that price. Unused bid amounts follow the published return rule.
The offered amount limits how many units the round can allocate.
A bid sets the highest price someone is willing to pay, not necessarily the final price.
If the last eligible tier has more demand than remaining supply, that tier is allocated proportionally.
Unfilled quantities and any difference between the maximum bid and clearing price remain unused.
