Description The smart contract uses the Ownable pattern, where the contract owner has special administrative privileges. These privileges allow the owner to perform tasks such as setting parameters, adjusting configurations, and possibly calling emergency functions. If the owner of the contract acts maliciously or carelessly, they could modify critical parameters or take other actions that negatively affect the contract's users, potentially resulting in significant financial loss or disruption to the service.
Impact If the contract owner has centralized control over the token distribution logic (such as determining how rewards or token dividends are divided among users), they could manipulate the distribution to their own advantage. This could lead to unfair allocation, where the owner or associated parties receive more than their fair share.
Moreover, if the owner has the ability to modify the structure (e.g., altering the percentages or conditions under which tokens and nfts are distributed), it could lead to significant financial losses for users. This can also skew incentives, affecting the long-term viability and sustainability of the project.
Proof of Concepts
Manipulating Token Pricing:
The owner adjusts the token price for buying to be extremely low for themselves, buying large quantities of tokens at an underpriced value.
Later, the owner increases the token price drastically (or artificially adjusts the pricing algorithm) when selling, profiting from the higher selling price, causing other users to incur financial losses when trying to buy the token at the inflated price
Manipulating Transaction Fees:
The owner increases the buy/sell fee, impacting users who wish to trade. This reduces the effectiveness of trades and increases the cost of participating in the token economy, leading to financial losses for users and benefiting the owner.
Recommended mitigation There are a few mitigations:
Decentralize Ownership with Multi-Signature Wallets:
Implement a multi-signature (multi-sig) wallet for the contract's admin functions. This means that changes to critical functions (e.g., pricing mechanisms, withdrawal rights) require approval from multiple trusted parties rather than a single owner.
Implement Role-Based Access Control (RBAC):
Use role-based access control to restrict critical functions such as changing prices, withdrawing funds, or modifying token allocations. Assign specific roles (e.g., "Admin," "Seller," "User") with clearly defined permissions, limiting the ability of any single user (including the owner) to execute high-risk actions.
