Unblock the Chain provides enterprise-grade blockchain security: smart contract audits, RWA tokenization assurance, and Web3 security for teams that can’t afford to ship vulnerable code.
Comprehensive security reviews of smart contracts and protocols. Identify vulnerabilities before deployment.
Security and compliance for real-world asset tokenization. Architecture review and risk assessment.
End-to-end blockchain security: protocol design, key management, and incident response for Web3 teams.
Design, architecture, and deployment of gas-optimized, production-ready contracts and decentralized finance protocols.
# Audit Finding: Reentrancy vulnerability in withdrawal logic Severity: CRITICAL Protocol: StakingVault ## Vulnerability Description The withdraw() function fails to update internal user balances before invoking external Ether transfers. An attacker could exploit this to recursively call withdraw() and drain the contract pool. ## Recommendation Implement the checks-effects-interactions pattern: balanceOf[msg.sender] -= amount; payable(msg.sender).transfer(amount);
A smart contract audit includes complete static and manual code analysis, logical structure checks, threat modeling, vulnerability testing (covering reentrancy, overflow, timestamp dependence, front-running, and oracle manipulation), and a detailed PDF report containing recommendations.
Yes. We specialize in real-world asset (RWA) security. We audit asset wrapper contracts, custodian interfaces, compliance locks, identity standards (like ERC-3643 or ERC-1400), oracle feeds, and standard ERC-20 structures.
Simply request an audit using the form below or email us directly at contact@unblockthechain.com. Send over your GitHub repository link and scope, and we'll reply with a detailed timeline and quote.
We combine automated analysis (static checkers, symbolic execution) with rigorous, multi-engineer manual reviews. We focus on finding business logic flaws and protocol-specific edge cases that automated tools can miss.
Yes. We provide dedicated remediation support. We work alongside your engineering team to explain vulnerabilities and review code changes during the fix phase, updating the final audit report accordingly.
