Submission Details
Severity:
[L-3] Missing event emission for deadline changes
Summary
While the contract emits an event for setting the deadline, it doesn't emit events for important state changes around the deadline.
Vulnerability Details
The contract lacks events for deadline-related state changes:
function setDeadline(uint256 _days) external onlyHost {
if(deadlineSet) {
revert DeadlineAlreadySet();
} else {
deadline = block.timestamp + _days * 1 days;
emit DeadlineSet(deadline);
}
}
Impact
Low: Harder to track deadline-related changes off-chain
Reduced transparency for event timing
Tools Used
Manual code review
Recommendations
Add more granular deadline events:
event DeadlineApproaching(uint256 timeRemaining);
event DeadlinePassed();
function setDeadline(uint256 _days) external onlyHost {
if(deadlineSet) {
revert DeadlineAlreadySet();
} else {
deadline = block.timestamp + _days * 1 days;
deadlineSet = true;
emit DeadlineSet(deadline);
}
}
