How it works: During the subscription period, users can freely deposit BNB (over-subscription is allowed). At the end of the period, the system calculates each participant's token allocation based on their contribution proportion of the total raised amount. Tokens are distributed at the preset rate, and any excess BNB is automatically refunded to the user's wallet. For Project Creators: It only costs 0.2 BNB to create the subscription pool. If the project is popular, over-subscription helps raise more funds. If the target is not reached by the deadline, full refunds are issued to all users — zero risk for the project.
