Audit Scope & Summary
Our smart contract security audit was conducted by SolidProof to identify potential vulnerabilities, optimize gas usage, and verify compliance with standard token architectures. The assessment analyzed the SPX Token smart contract code, presale allocation contracts, and staking pools.
Result Summary: SolidProof identified 0 Critical, 0 High, 0 Medium, and 0 Low-severity issues. The codebase aligns with modern blockchain security standards and incorporates robust safeguards to prevent exploitation or unexpected behaviors.
Vulnerability Analysis Checklist
Reentrancy Vulnerability — Secured
Protected using OpenZeppelin ReentrancyGuard and Checks-Effects-Interactions pattern.
Integer Overflow / Underflow — Secured
Compiled using Solidity 0.8.20 which has built-in compiler checks for arithmetic safety.
Access Control & Privileges — Secured
Role-based access controls verified. Owner functions are correctly restricted and secure.
Gas Limit & Loops — Secured
No unbounded loops or storage arrays. Gas consumption is optimized and bounded.
Denial of Service (DoS) — Secured
Pull-payment patterns implemented for refunds and withdrawals to prevent denial of service.
Oracle Manipulation & Flash Loans — Secured
Not applicable to core contract. Prices are calculated dynamically based on controlled admin stages.
Timestamp Dependency — Secured
Timestamps used only for stage transitions with reasonable safety margins.
Tx.Origin Exploits — Secured
Only msg.sender is used for access authentication throughout all functions.
Key Security Strengths
- Vesting & Lockups: Team and developer token shares are locked using immutable on-chain vesting contracts, preventing sudden token dumps or rugpull scenarios.
- KYC Verification: The core team has completed official KYC verification procedures with SolidProof to establish legal compliance and builder transparency.
- Multi-Sig Control: Critical settings require consensus via a multi-signature safe wallet setup.
