SlowMist noted that the JUMPBonusPool contract was originally designed with two core mechanisms i.e, Bonus Pool Mechanism and Time Extension Mechanism. The Bonus Pool allows the last five users to participate in donations and would equally split the accumulated ETH bonus. On the other hand, Time Extension Mechanism allows extension of game time by 30 seconds each time a user makes a donation.

SlowMist shared, “Yesterday, the project team used the owner permissions to modify the JUMPTreasury contract’s designated JUMPBonusPool contract twice through the setEmergencyBonusPool function. The relevant transactions are as follows:

The blockchain security firm found that this modification prevents users from taking part in the competition for the accumulated bonus in the original JUMPBonusPool contract (https://etherscan.io/address/0x8f8eb567a9f875180eED690Dd231fd9619bb09A7#code…) through normal donations. Note that the newly replaced JUMPBonusPool contract has not been open-sourced.

JUMPFUN’s modifications are “severely inconsistent” with the activity rules mentioned by the project team and thus are irregular. In the wake of these discrepancies, SlowMist has advised users to be vigilant of the risks and proceed with caution.

Note that, there has not been any comments from JUMPFUN team on these observations made by SlowMist, as of yet. Just yesterday, SlowMist had detected several inconsistencies in SUI network’s OceansGallerie. The security firm advised precautionary measures, when it found that the project had been removing liquidity and had somewhat centralized the token allocation.
