# Pre-sale

Alts in Alt.town sell 10% of their DNA supply during the pre-sale period. 70% of the total sales revenue from the pre-sale will be allocated to the respective Alts. The pre-sale is a *fixed-price sale*, meaning only buying is available during this period, and selling is not allowed.

The sale period is 7 days from the date of move-in, with a total of 3 rounds: the first round lasts for 48 hours, the second round lasts for 48 hours, and the third round lasts for 72 hours. The sale price is based on a base price set by Alt, with the first round offering a 50% discount off the base price, the second round offering a 30% discount, and the third round selling at the base price.

If the quantity for a round is sold out after the round opens, purchasing will not be available until the next round begins. If there are unsold quantities during a round, they will not be carried over to the next round. Instead, after the pre-sale ends, those unsold quantities from each round will be combined and moved to the ecosystem wallet. Unsold quantities moved to the ecosystem wallet will be locked up for one year, after which they will be allocated at a rate of 2.5% per month (1.25% each for Alt and the service). The amount allocated to the service will be utilized as event supply for the respective Alt.
