ChainCatcher message, Slow Mist Yu X stated: "According to feedback from Slow Mist's intelligence personnel, the JUMPFUN project (@jumpdotfun) is suspected of suspicious behavior. After analyzing the project contract and transaction records, we found the following suspicious situations:The JUMPBonusPool contract was originally designed with two core mechanisms:Bonus Pool Mechanism: The last 5 users who participate in donations can share the accumulated ETH bonus.Time Extension Mechanism: Each time a user makes a donation, the game time will be automatically extended by 30 seconds.Yesterday, the project party used owner privileges to modify the JUMPTreasury contract's reference to the JUMPBonusPool contract twice through the setEmergencyBonusPool function.This modification prevented users from participating in the grand prize competition of the previously accumulated bonuses in the JUMPBonusPool contract through normal donations. It is worth noting that the newly replaced JUMPBonusPool contract has also not been open-sourced.These actions are in serious violation of the activity rules previously disclosed by the project party, showing obvious misconduct. We remind all participating users to be aware of the risks and participate cautiously."
