Audit Report
Project Name: Rox Finance Contract Name: Rox Audit Date: 30 January 2025 Audited By: Rox Security Team
Introduction
The Rox Token is an ERC-20 compliant token designed with enhanced functionality, including:
A configurable transaction fee mechanism.
Fee distribution among multiple recipients based on basis points.
Minting and burning capabilities, allowing the owner to control token supply.
Ownership-based access control for administrative tasks.
This audit evaluates the correctness, security, and efficiency of the smart contract.
Scope of Audit
The scope of this audit includes:
Code Analysis: Reviewing the implementation for logical and functional correctness.
Security Assessment: Identifying vulnerabilities in the contract.
Gas Efficiency: Evaluating the efficiency of functions.
Compliance: Verifying compliance with the ERC-20 standard.

Detailed Findings
1. General Implementation
The contract follows the ERC-20 standard and extends functionality using:
ERC20Burnable: Allows token holders to burn their tokens.
Ownable: Provides ownership-based administrative control.
Key Functions Implemented:
mint
: Allows the owner to mint tokens.transfer
&transferFrom
: Includes a fee distribution mechanism.setFeeBasisPoints
&setFeeRecipient
: Enables the owner to configure fee parameters.
Finding: The implementation adheres to best practices.
2. Security Review
Access Control
Functions like
mint
,setFeeBasisPoints
, andsetFeeRecipient
are restricted to the owner.Ownership is managed using OpenZeppelin’s
Ownable
module.
Finding: No unauthorized access vulnerabilities identified.
Fee Distribution Mechanism
The fee is calculated and distributed among configured recipients.
Ensures that the sum of recipient basis points does not exceed 100% (10,000 basis points).
Finding: Secure and correctly implemented.
Token Transfers
Tokens are transferable while deducting fees if applicable.
Proper checks ensure fees and remaining amounts are handled accurately.
Finding: Passed all security tests.
3. Gas Optimization
The contract is designed with gas efficiency in mind:
Looping over fee recipients is optimized with checks to prevent unnecessary iterations.
Fee calculations leverage basis points for accuracy and simplicity.
Recommendation: While the fee distribution mechanism is efficient, it is recommended to limit the number of fee recipients to prevent high gas costs in edge cases.
4. Compliance
The contract is fully compliant with the ERC-20 standard:
Implements

, andtransferFrom
as required.Adheres to OpenZeppelin’s widely trusted implementations for ERC-20 functionality.
Finding: Fully compliant.

Recommendations
Limit Fee Recipients: While the contract ensures efficient fee distribution, limiting the number of fee recipients can reduce potential gas costs in edge cases.
Future Updates: Consider integrating upgradeable patterns for enhanced flexibility in future updates.
Security Audit Re-Runs: Reassess the contract after any modifications or updates to ensure continued security compliance.
Conclusion
The Rox Token contract is secure, efficient, and compliant with the ERC-20 standard. It incorporates a robust fee mechanism and follows best practices in smart contract development. The code is well-documented and ready for deployment.
