After analyzing the project contract and transaction records, we found the following suspicious situations: The JUMPBonusPool contract was originally designed with two core mechanisms: 1. Bonus pool mechanism: The last 5 users who participate in the donation can share the accumulated ETH bonus equally 2. Time extension mechanism: Every time a user makes a donation, the game time will be automatically extended by 30 seconds Yesterday, the project party used the owner permission to modify the JUMP BonusPool contract pointed to by the JUMP Treasury contract twice through the setEmergencyBonusPool function. This modification has prevented users from participating in the jackpot competition of the JUMPBonusPool contract that has accumulated winnings through normal donations. It is worth noting that the newly replaced JUMPBonusPool contract has not been open-sourced. These behaviors are seriously inconsistent with the description of the activity rules previously disclosed by the project party, and there are obvious violations. All participating users are reminded to be aware of risks and participate cautiously. "
