The FourChan token contract is an ERC-20 compliant token with reflection mechanics, high transaction taxes, and anti-bot features. A critical vulnerability arises from the renounced ownership, which renders all owner-controlled functions immutable, including critical parameter adjustments and fee management. This severely limits the project's adaptability and ability to respond to market changes or security incidents. Additionally, the contract features aggressive anti-bot measures that could inadvertently block legitimate users and high, irreversible tax rates.

How holder types affect the score
Share held by contracts — treasury, vesting, bridge or staking — is discounted against share held by wallets when the score is computed: a contract cannot decide to sell the way an anonymous holder can, though it can still be drained or voted to sell. Effective concentration is the figure the risk score is actually calculated from.

Fix
For future projects, if ownership renunciation is intended, ensure that all critical parameters are optimally configured and thoroughly tested beforehand. Consider implementing a timelock or a multi-signature wallet for critical administrative functions if some level of post-deployment control is desired without full centralization. For this specific contract, given the renounced ownership, this issue is irreversible.

HighIrreversible High Tax Rates and Centralized Parameters
The contract is designed with high buy (20%) and sell (35%) taxes, and critical parameters such as _maxTxAmount, _maxWalletSize, and fee recipient addresses are controlled by the owner. Given that ownership is renounced, these parameters are now immutable. This means the project cannot adjust to market conditions, reduce taxes, or change fee recipients, which could negatively impact token utility, adoption, and the project's ability to respond to future needs or security concerns (7.4 Economic, 7.5 Governance).H-01

Fix
For future projects, carefully evaluate the long-term implications of fixed high tax rates and other critical parameters. If ownership is to be renounced, consider a mechanism for community governance or a timelock to allow for parameter adjustments, or ensure that initial parameters are sustainable and acceptable for the project's lifespan. For this contract, these parameters are permanently fixed.

MediumAggressive Anti-Bot Mechanism May Block Legitimate Users
The _transfer function includes an aggressive anti-bot mechanism: require(_buyMap[from] == 0 || preTrader[from], "Bot detected");. This logic prevents any address from making a second buy transaction unless that address is explicitly added to the preTrader whitelist by the owner. This could inadvertently block legitimate users who are not preTraders from making subsequent purchases, leading to a poor user experience and potential loss of trust. Furthermore, the preTrader list itself is centrally controlled by the owner (7.2 Code Security, 7.3 Access Control).M-01

Fix
Review the anti-bot mechanism to ensure it does not unfairly penalize legitimate users. Consider alternative, less restrictive anti-bot strategies or implement a more transparent and decentralized process for managing whitelists. Given renounced ownership, this mechanism cannot be modified, so clear communication to users about this restriction is vital.

LowSingle Address for Development and Marketing Fees
Both _developmentAddress and _marketingAddress are set to the same address (0xB2e0…3FCD). While this might be intentional, it centralizes the destination of all collected fees into a single wallet. This increases the single point of failure risk, as compromise of this one address would lead to the loss of all accumulated development and marketing funds (7.4 Economic, 7.8 Operations).L-01
Issue
Both _developmentAddress and _marketingAddress are set to the same address (). While this might be intentional, it centralizes the destination of all collected fees into a single wallet. This increases the single point of failure risk, as compromise of this one address would lead to the loss of all accumulated development and marketing funds (7.4 Economic, 7.8 Operations).
Fix
For future projects, consider using separate addresses for different fund allocations to diversify risk. Ideally, these addresses would be multi-signature wallets to enhance security. Given renounced ownership, this configuration is immutable for this contract.

InfoRedundant SafeMath Usage
The contract explicitly uses the SafeMath library for arithmetic operations (e.g., amount.sub(...)). However, the contract is compiled with Solidity ^0.8.14, which includes built-in overflow and underflow checks by default. Therefore, the explicit use of SafeMath is redundant and adds unnecessary code complexity without providing additional security benefits (7.2 Code Security).I-01

Therefore, the explicit use of SafeMath is redundant and adds unnecessary code complexity without providing additional security benefits (7.2 Code Security).
Fix
For future contracts compiled with Solidity 0.8.0 or higher, SafeMath can be safely removed to reduce code size and improve readability, as the compiler handles overflow/underflow checks automatically. This is an informational finding and does not pose a security risk to the current contract.

Analysis
AI Copilotas of audit · Sep 4The contract demonstrates a structured approach to tokenomics, incorporating reflection and fee mechanisms. It utilizes SafeMath for arithmetic operations, although redundant in Solidity 0.8+, and includes a reentrancy guard (inSwap) for its swapAndLiquify function (7.2 Code Security). However, the custom anti-bot mechanism, specifically the _buyMap logic, is highly restrictive and could lead to legitimate users being blocked (7.2 Code Security). The overall architecture is standard for a deflationary token, but its rigidity due to renounced ownership presents significant operational challenges (7.1 Architecture).
The contract's economic model is characterized by high buy (20%) and sell (35%) taxes, which are designed to fund development and marketing (7.4 Economic). However, with ownership renounced, these tax rates are immutable, preventing any adjustments to adapt to market conditions or community feedback (7.5 Governance). The centralized control over critical parameters, now permanently fixed, poses a high risk to the project's long-term viability and flexibility (7.3 Access Control). Furthermore, both development and marketing fees are directed to a single address, centralizing fund distribution (7.4 Economic).
The FourChan contract is not designed with any upgradeability mechanism (7.7 Upgrades). This means its logic and parameters are immutable once deployed and ownership is renounced. While this eliminates upgrade-related risks, it also prevents any future bug fixes, feature enhancements, or parameter adjustments, contributing to the overall rigidity of the protocol.
Given the renounced ownership, the project's ability to adapt or correct issues is severely limited.
It is crucial for users to understand that all owner-controlled parameters, including tax rates and anti-bot mechanisms, are permanently fixed. Future projects should carefully consider the implications of renouncing ownership, especially for highly configurable tokens, and ensure that all critical parameters are set optimally before doing so. If such a design is intentional, clear communication to the community about the immutability of these parameters is essential.
