Lack of Events

blockchainbard

Summary

The smart contract does not emit events after important state changes, such as the successful swapping of tokens or transferring tokens to the staking contract.

Vulnerability Details

Events are crucial for tracking the activities of a contract. They provide a way for frontends and external applications to react to changes on the blockchain. However, this contract does not emit events after key state changes, making it harder to track its activities.

Impact

This lack of transparency can make it difficult to integrate the contract with other systems or to track its actions for debugging or audit purposes.

Tools Used

Manual review of the smart contract code.

Recommendations

Consider emitting events after major state changes. For example, after a successful token swap, you could emit an event like this:

event TokensSwapped(address indexed profitToken, uint256 amount);
​
And after transferring WETH to the staking contract:
​
```solidity
event TransferToStaking(address indexed stakingContract, uint256 amount);
​
