The setRaiseAmount function presents a significant centralization risk, allowing the deployer to unilaterally manipulate the dynamic transaction fees. The contract is designed to automatically lower fees from 4% to 0% as ETH fundraising milestones are met. However, this function lets the deployer arbitrarily change the raiseAmount variable, which controls these fee tiers. The deployer could unfairly reset fees to the maximum 4% even after targets are met, or prematurely eliminate fees by setting the amount high. This undermines the predictability and fairness of the token's economic model, giving the deployer arbitrary control over the fee structure instead of letting it be driven by actual fundraising performance.

The _handleAccumulation function contains a critical logic flaw that renders its primary feature non-functional. The function is intended to "subtly accumulate" a small, random portion of fee tokens by withholding them from being swapped for ETH. However, due to a bug in the code, the contract always swaps the entire fee amount, even when it randomly decides to "accumulate." An event is emitted suggesting tokens were retained, but they are sold immediately. This bug is compounded by the use of predictable on-chain data (like block.timestamp and msg.sender) for its random number generation. This predictability would allow sophisticated bots to anticipate the function's behavior, but more importantly, it exposes the underlying flaw: the "subtle accumulation" system is entirely non-operational and misleading.

The _swapTokensForETH function incorrectly calculates the amount of ETH received from a Uniswap trade. It measures the contract's entire ETH balance after the swap and assumes that total is the amount received. This creates a critical accounting bug if a previous ETH distribution failed, leaving a residual ETH balance in the contract. For example: imagine the contract receives 1 ETH, but only successfully sends out 0.5 ETH, leaving 0.5 ETH stuck. On the next swap, it receives another 1 ETH. The contract's balance is now 1.5 ETH, and the function incorrectly records this entire amount as newly received funds. This inflates the raiseAmount, causing the dynamic fee system to lower fees prematurely based on misleading fundraising totals.

The setFeeOverride function grants the DEPLOYER_WALLET the extreme power to unilaterally set buy and sell fees as high as 50%. This function bypasses all other fee mechanisms in the contract, including the automated launch and dynamic fee schedules. A malicious or compromised deployer could abuse this function to effectively trap user funds by setting sell fees to an unsustainable level, making it impossible for holders to sell their tokens without incurring massive losses. This represents a severe centralization risk, as it gives one address complete and immediate control over the token's trading viability, undermining trust in the project's economic rules.

The contract contains a re-entrancy vulnerability that stems from a violation of the Checks-Effects-Interactions security pattern within the _checkPeriodicSwap function. This function, called at the end of every _transfer, executes an external call via _swapTokensForETH before it updates its own state by setting the lastSwapTime. This incorrect ordering creates a window for attack. An attacker who compromises the owner's account can set the marketingWallet to a malicious contract. When that contract receives ETH from a swap, it can immediately call transfer() again, re-entering the function. Because lastSwapTime has not been updated, the checks pass again, allowing the swap to be re-triggered repeatedly within a single transaction to drain all swappable tokens.
