Summary

The smart contract relies on block.timestamp for calculating timeElapsed , which can be manipulated by miners, potentially leading to security vulnerabilities.

Vulnerability Details

The contract utilizes the block.timestamp variable to make decisions based on the current block's timestamp. However, miners have some control over the timestamp's value within a certain range, allowing them to manipulate the timestamp to a certain extent.

Code Snippet

Impact

Miners' ability to influence the block.timestamp can introduce significant security risks to the contract.

Recommendations

Consider using block.number or other block-related variables, which are less susceptible to manipulation by miners, for any time-dependent functionalities or decision-making processes.
