Submission Details
Severity:
Insufficient Event Emissions for Key Actions
Vulnerability Details:
The contract does not emit events for several important actions, such as ending the auction or claiming tokens.
Impact:
Lack of events makes it difficult to track important state changes off-chain, complicating the development of user interfaces and making the system less transparent.
Proof of Concept:
The auctionEnd() and claimTokens() functions do not emit any events.
Tools Used: Manual review
Recommendations:
Add events for all significant state changes. For example:
event AuctionEnded(uint256 totalBids, uint256 multiplier);
event TokensClaimed(address indexed user, uint256 amount);
function auctionEnd() external {
// ... existing code ...
emit AuctionEnded(totalBids, multiplier);
}
function claimTokens() external {
// ... existing code ...
emit TokensClaimed(msg.sender, claimable);
}
