Vaultium (VLTM) Audit
Complete security evaluation and code review of Vaultium (VLTM) BEP-20 token smart contract
Project Overview
Vaultium (VLTM) is a reflection based BEP-20 token with automatic rewards distribution. The token implements a 3% transaction tax split between reflection rewards (1%), marketing wallet (1%), and automatic burn (1%).
Audit Status
No critical vulnerabilities found. Low risk issues identified in centralization and architecture patterns.
Contract Details
Key Findings
Audit Scope
The security assessment was focused on identifying vulnerabilities in the smart contract code that could potentially lead to:
- Fund loss or token theft
- Unauthorized minting of tokens
- Front running attacks
- Logic errors in reward calculations
- Reentrancy vulnerabilities
- Access control weaknesses
- Owner privilege abuse
- MEV protection bypass
- Blacklist functionality abuse
- Fee distribution vulnerabilities
- Denial of service attacks
Audit Findings
The contract is functionally safe with moderate centralization considerations that should be noted by users but do not prevent safe operation.
Detailed Findings
Low Risk Findings
L-01: Fee Exclusion Mechanism
The owner can exclude specific addresses from paying transaction fees using the excludeFromFee function. This is a standard administrative pattern in DeFi tokens allowing the contract owner and marketing wallet to transfer without incurring fees. The functionality is transparent and commonly used for operational purposes.
Impact: Minimal risk. Standard DeFi pattern for administrative addresses. Users should be aware of which addresses are fee exempt.
L-02: Reward Exclusion System
The owner can exclude addresses from receiving reflection rewards, which is necessary for technical reasons (e.g., excluding DEX pairs and burn wallet from accumulating rewards). The includeInReward function uses array iteration which could be gas intensive with many exclusions, but in practice, only a few addresses (DEX pair, burn wallet) need exclusion.
Impact: Low risk. Necessary for proper reflection mechanics. Gas costs manageable with limited exclusions.
Recommendations & Conclusion
Overall Risk Level: LOW
Positive Aspects:
- Proper BEP-20 standard compliance with complete interface implementation
- Uses Solidity 0.8.30 with built in overflow/underflow protection
- Modern error handling using custom errors for gas efficiency
- Fixed 3% tax structure (1% reflection, 1% marketing, 1% burn) that cannot be increased
- Automatic reward distribution through reflection mechanism benefiting all holders
- Comprehensive event emission for transparency and tracking
- Well documented code with detailed NatSpec comments
- No critical or medium vulnerabilities identified
- No fund theft vectors or exploitation paths found
- Proper access control with Ownable pattern
- Standard administrative functions common in DeFi tokens
- Transparent fee and reward exclusion mechanisms
Low Risk Findings:
- L-01: Fee exclusion mechanism, standard administrative pattern for DeFi tokens
- L-02: Reward exclusion system, necessary for technical requirements (DEX pairs, burn wallet)
Recommendations:
- Document which addresses are excluded from fees/rewards for user transparency
- Maintain a reasonable limit on excluded addresses (recommended: less than 10)
- Implement comprehensive testing for reflection calculations with various scenarios
- Maintain transparent communication with community about fee exclusions
✅ Deployment Status
This contract is successfully deployed on BSC Mainnet and is live on PancakeSwap. The token is actively trading with liquidity established on the decentralized exchange.
The reflection mechanism is operating efficiently with a limited number of excluded addresses. Exclusions are properly maintained for essential addresses only (DEX pair, burn wallet, and operational addresses).
✅ Security Assessment
The Vaultium token implements a well designed reflection based reward mechanism with a reasonable and transparent tax structure. The code follows industry best practices, is thoroughly documented, and includes proper safety checks. No critical or medium risk vulnerabilities were identified. All administrative functions are standard for reflection tokens and operate transparently with event emissions. The contract is ready for deployment with only minor gas optimization recommendations.
The HashKode security team has completed a comprehensive analysis of the Vaultium (VLTM) smart contract and found it to be well implemented with excellent security standards. The contract follows industry standard patterns for reflection tokens with proper safeguards in place. Only two low risk findings were identified, both relating to standard administrative features that are necessary for proper token operation. The contract demonstrates excellent code quality, thorough documentation, and secure design patterns. The token is now successfully deployed and actively trading on BSC mainnet with established liquidity on PancakeSwap.
