# Smart Contract Audit – August 2025 ### Scope of the Audit The audit covered Pulse.sol, the BEP-20 smart contract powering the Pulse (XPL) token. Key features included: * Reflection mechanism for automatic holder rewards. * Liquidity provisioning via PancakeSwap. * Configurable tax and liquidity fees. * Owner-controlled burn functionality. * Protection against reentrancy and other common vulnerabilities. *** ### Results * Audit Score: 91 / 100 – PASS * Critical Issues: 0 * High Issues: 0 * Medium Issues: 4 (Acknowledged) * Low Issues: 1 (Acknowledged) * Informational Notes: 5 This score reflects strong overall contract integrity, with no critical or high-risk vulnerabilities identified . *** ### Key Findings * No Slippage Protection in Swaps (Medium, Acknowledged): Potential exposure during high market volatility. * Unbounded Loops (Medium, Acknowledged): Could theoretically cause out-of-gas errors. * Liquidity Threshold Too High (Medium, Acknowledged): Could lead to idle tokens in contract. * Burn Mechanism Behavior (Medium, Acknowledged): Burns do not directly boost holder balances. * Fee Setter Flexibility (Low, Acknowledged): Recommended to add bounds when setting fees. * Gas Optimization Suggestions (Informational): Include use of custom errors, external functions, caching storage reads, and naming conventions. *** ### Zokyo’s Recommendations * Implement slippage tolerance and transaction deadlines. * Refactor reward inclusion to avoid unbounded loops. * Adjust liquidity thresholds to realistic levels. * Consider improvements to burn mechanics. * Apply gas efficiency practices for long-term optimization. * Introduce a bug bounty program to encourage continuous testing . *** ### Conclusion The audit validates that Pulse World’s smart contracts are secure, reliable, and aligned with industry best practices, with only medium-level optimizations suggested. This result reflects Pulse World’s commitment to safeguarding community assets and building a robust ecosystem that integrates DeFi, GameFi, SocialFi, Web3, and NFTs into one metaverse. ### 🔗 View the full Zokyo Audit Report {% file src="" %}
