COMPREHENSIVE SECURITY & USABILITY REVIEW
What Our Substrate Wallet Audit Delivers
Our audit provides a detailed, actionable report that goes beyond vulnerability detection to ensure your wallet is secure, user-friendly, and ready for production. We deliver the technical clarity your team needs to build with confidence.
01
Security Vulnerability Assessment
In-depth analysis of your wallet's cryptographic implementations, key management, and transaction signing logic. We identify critical risks like private key leakage, replay attacks, and insufficient entropy.
02
Usability & UX Review
Evaluation of the user journey for key actions (signing, staking, governance). We flag confusing prompts, missing confirmations, and poor error handling that lead to user loss of funds.
03
Substrate-Specific Best Practices
Review against Polkadot/Substrate ecosystem standards, including proper use of @polkadot/api, handling of chain upgrades, and integration with extension libraries like @polkadot/extension-dapp.
04
Gas & Fee Optimization Analysis
Benchmarking of transaction costs and identification of optimization opportunities in extrinsic construction and payload handling to reduce user friction and failed transactions.
05
Detailed Remediation Report
Prioritized list of findings with severity ratings, code-level examples of vulnerabilities, and clear, actionable remediation steps for your engineering team.
06
Post-Audit Support & Consultation
30-day support window to help your team understand findings, review fixes, and answer technical questions, ensuring vulnerabilities are properly resolved before launch.

RIGOROUS & TRANSPARENT
Our Methodology: The Chainscore Audit Process
A systematic, multi-layered approach designed to uncover critical vulnerabilities and deliver actionable, prioritized insights for immediate remediation.
01
1. Architecture & Specification Review
We analyze your wallet's design, key management flows, and integration points against Substrate best practices. This foundational review identifies systemic risks before code-level testing begins.
02
2. Automated Vulnerability Scanning
Leveraging proprietary and industry-standard tools to perform static and dynamic analysis. We scan for common OWASP Top 10 issues, insecure dependencies, and known Substrate/Pallet vulnerabilities.
03
3. Manual Code & Logic Review
Our senior auditors conduct line-by-line reviews of core logic, focusing on transaction signing, seed phrase handling, RPC interactions, and custom pallet integrations. This is where subtle, high-impact flaws are discovered.
04
4. Threat Modeling & Attack Simulation
We simulate real-world attack scenarios, including front-running, phishing, man-in-the-middle attacks on RPC endpoints, and malicious dApp interactions to test the wallet's defensive resilience.
05
5. Usability & UX Security Assessment
Evaluating the user interface for security pitfalls: clear transaction signing prompts, phishing detection, seed phrase backup flows, and permission management to prevent user error and social engineering.
06
6. Reporting & Remediation Support
Receive a detailed, prioritized report with CVSS-scored findings, proof-of-concept exploits, and clear remediation guidance. We provide direct consultation to ensure all issues are resolved effectively.

Expert Insights
Substrate Wallet Audit FAQs
Get clear answers to the most common questions CTOs and technical leads ask about our specialized Substrate wallet security and usability audit process.
A comprehensive audit typically takes 2-3 weeks from kickoff to final report delivery. This includes a 1-week deep-dive security review, a 1-week usability and architecture assessment, and a final week for remediation guidance and report finalization. For complex multi-chain or multi-signature wallets, the timeline may extend to 4 weeks.
