Blockchain Security Auditing Services

Verichains provides comprehensive blockchain security auditing services covering smart contracts, blockchain protocols, and cryptographic systems. With a proven track record since 2017, Verichains is trusted by major blockchain networks including BNB Chain, Aptos, Sui, Ronin, and Wemix for auditing mainnet updates and core protocol changes.

Smart Contract Security Reviews

Comprehensive smart contract security reviews covering design analysis, automated code scanning, and manual auditing in any programming language including Solidity, Move, and Rust. Our audits identify common vulnerabilities including reentrancy attacks, integer overflows/underflows, and access control flaws. We detect business logic flaws and address economic-related issues such as price manipulation, incorrect slippage, and unprotected liquidation. Our process ensures proper validation of external inputs and interactions to safeguard against potential risks.

Protocol-Level Security Assessment

Blockchain protocol security assessment covering critical components from core chains to bridges, oracles, and scaling solutions. Our consensus protocol review identifies weaknesses that could compromise the protocol's liveness and safety, ensuring that consensus mechanisms are resilient against vulnerabilities that could disrupt network operations. Our node security assessment verifies that nodes are resistant to attacks such as impersonation, isolation, and crashes caused by malformed transactions. We focus critically on the correctness of protocols for state transitions, specifically for rollups and state changes between L1 and L2, ensuring these transitions are secure and operate correctly to prevent exploitable vulnerabilities.

Cryptographic Protocol Auditing

Specialized cryptography audit services evaluating and securing cryptographic protocols to ensure robustness against design flaws that can create severe, often subtle vulnerabilities. We begin with comprehensive design assessment, identifying flaws, evaluating algorithm security, and refining threat models. Our code assessment examines both standardized and novel cryptographic systems, including public key infrastructures, threshold signature schemes, Multi-Party Computation (MPC), Threshold Signature Schemes (TSS), zero-knowledge circuits, and Zero-Knowledge Proofs (ZKPs) for vulnerabilities and implementation flaws. Our expertise includes the TSSHOCK research project, a comprehensive security survey of MPC that has safeguarded billions of dollars in digital assets.

Deliverables & Support

Deliverables include comprehensive security reports detailing identified vulnerabilities, severity levels, recommended fixes, and follow-up re-audits to verify applied fixes. Our team provides dev-to-dev support throughout the assessment, answering technical questions and guiding clients through vulnerability remediation for effective fixes. We provide in-depth analysis reports detailing identified vulnerabilities, potential impacts, and suggestions for cryptographic improvements.
