PROVEN PROCESS
Our Audit Methodology
Our systematic, multi-layered approach ensures no vulnerability goes undetected. We deliver actionable reports that empower your team to secure your identity wallet before launch.
01
Architecture & Design Review
We analyze your wallet's architecture against OWASP Top 10 for Web3 and W3C DID standards. We identify flaws in key management, delegation logic, and interoperability risks before a single line of code is tested.

Compliance Check
OWASP Web3
Framework
02
Manual Code Review
Senior auditors conduct line-by-line analysis of core smart contracts (e.g., ERC-4337 Account Abstraction, ERC-725/735) and SDKs. We focus on cryptographic implementations, access control, and logic errors automated tools miss.

Automated Vulnerability Scanning
We run a battery of static and dynamic analysis tools (Slither, MythX, Foundry) against your codebase. This catches common vulnerabilities like reentrancy, integer overflows, and signature replay attacks at scale.

THE FOUNDATION OF TRUST
Why a Specialized Identity Audit is Critical
Decentralized identity wallets manage sensitive user data and access rights. A generic smart contract audit is insufficient. Our specialized audit targets the unique vulnerabilities and compliance requirements of identity systems.
01
Zero-Knowledge Proof Integrity
We audit the cryptographic soundness of ZK circuits (Circom, Halo2) and privacy-preserving verification logic to prevent identity forgery and data leakage.

Credential Schema & VC Compliance
Verification of W3C Verifiable Credential data models, revocation mechanisms, and selective disclosure patterns to ensure interoperability and standards adherence.

Decentralized Identity Wallet Audit FAQs
Get clear, technical answers to the most common questions about our security audit process for decentralized identity wallets and SSI solutions.
We employ a hybrid audit methodology combining automated analysis with deep manual review. Our process includes: 1) Architecture Review of key management, credential flows, and privacy models (e.g., ZKPs, selective disclosure). 2) Smart Contract Security using static analysis (Slither) and manual line-by-line review for logic flaws. 3) Cryptographic Review of signature schemes (EdDSA, BBS+), key derivation, and zero-knowledge circuits. 4) Integration Testing against W3C DID/VC standards and target blockchains (Ethereum, Polygon, Solana). This comprehensive approach has secured over $200M in digital assets across 30+ identity projects.
