The fourth category: the total amount of crowdloan ≥ 25,000 KSM. If the total amount of crowdloan participating in the project through SlotVault is greater than or equal to 25,000 KSM, then a contributor’s reward is determined based on that individual’s proportional contribution to the total number of KSM tokens in the crowdloan at auction close, for example, Your ZLK Rewards = (Your KSM Contribution From SlotVault/Total KSM Contributions From SlotVault) * 150,000 ZLK.
