COMPREHENSIVE SECURITY REVIEW
What Our Decentralized Identity Audit Covers
Our audit methodology is designed for CTOs and engineering leads who need to ship secure, compliant identity protocols. We deliver actionable reports that go beyond vulnerability detection to include architectural risk and gas optimization.
01
Smart Contract & Protocol Logic
In-depth review of your core identity logic (Soulbound Tokens, Verifiable Credentials, ZK proofs) for reentrancy, access control flaws, and business logic errors. We test against the OWASP Top 10 for Web3.

Code Coverage
48 hrs
Critical Issue SLA
02
Cryptographic Implementation Review
Verification of signature schemes (EIP-712, ECDSA), zero-knowledge circuit logic (Circom, Halo2), and key management. We ensure your cryptographic primitives are implemented correctly and resist side-channel attacks.
Zero Trust

FIPS 140-2
Standards Check
03
Integration & Dependency Analysis
Security assessment of all external integrations: oracles for attestation, cross-chain bridges for identity portability, and wallet providers. We map attack surfaces introduced by third-party dependencies.

Gas Optimization & Cost Analysis
Detailed gas profiling for on-chain identity operations (minting, revocation, verification). We identify inefficiencies that could make your protocol prohibitively expensive at scale, providing optimized alternatives.

Compliance & Regulatory Alignment
Analysis of your architecture against relevant frameworks: GDPR right-to-erasure, FINRA record-keeping, and travel rule compliance. We provide a gap analysis for privacy-preserving design patterns.

Why a Specialized DID Audit is Critical
Standard smart contract audits miss the unique attack vectors in decentralized identity systems. Our specialized reviews target the protocols, cryptography, and privacy models that protect user sovereignty.
01
Protocol-Specific Expertise
We audit against the specifications of W3C DID Core, Verifiable Credentials, and OIDC SIOPv2. Ensures your implementation is interoperable and compliant with emerging standards.

Cryptographic & Key Management Review
Deep analysis of signature schemes (EdDSA, BBS+), key derivation, and revocation logic. Prevents private key leakage, signature malleability, and replay attacks specific to DID workflows.

Decentralized Identity Audit FAQs
Get clear answers on our security review process, timeline, and deliverables for your SSI, Verifiable Credentials, or DID-based project.
We employ a four-phase methodology tailored for identity protocols: 1) Architecture Review (DID methods, VC schemas, revocation models), 2) Smart Contract & Protocol Analysis (Solidity/Vyper for on-chain registries, zero-knowledge circuits), 3) Cryptographic Security Assessment (signature schemes, key management, ZK-SNARK/STARK soundness), and 4) Integration & Client-Side Review (wallet SDKs, agent security). Our process is based on NIST guidelines and the W3C DID/VC specifications.
