Summary

possibility of unclaimed tokens due to user inaction

Vulnerability Details

In the current auction contract, there is a risk that some users may fail to claim their auction tokens after the auction ends. This can lead to a scenario where a portion of the auction tokens remains unclaimed and locked in the contract, potentially reducing the overall token distribution and diluting the intended impact of the auction. Unclaimed tokens could also result in a loss of value for participants and the project, as these tokens remain idle and unutilized.

Proof of Concept (PoC)

The auction reaches its end time, and the auctionEnd function is called, finalizing the auction and calculating the number of auction tokens each participant can claim based on their bids.
Users Fail to Claim:

Some users, for various reasons (e.g., lack of awareness, lost private keys, or disinterest), do not call the claimTokens function to claim their allocated auction tokens.

As a result, the unclaimed tokens remain in the contract. These tokens are not redistributed or utilized, leading to a situation where a portion of the auction tokens does not reach the market or intended users.
Impact:

The overall tokenomics could be disrupted, as the unclaimed tokens could create an artificial scarcity or result in unintended token allocation.

Recommendations

To address the issue of unclaimed tokens and ensure a smooth and fair distribution process, consider implementing the following strategies:

Automatic Redistribution:

Introduce a mechanism to automatically redistribute unclaimed tokens to other bidders proportionally after a certain period. This ensures that all auction tokens are eventually claimed and put into circulation.
Claiming Deadline:

Set a deadline for users to claim their tokens. If tokens remain unclaimed after this period, they could either be burned (reducing the total supply) or transferred back to the project treasury for future use.
