What we do for you
Wallet architecture analysis
We examine how your wallet is designed: local or remote key storage, cryptographic schemes, and interaction with Web3 infrastructure. Identify architectural risks and provide mitigation strategies.
Private key security review
We analyze how private keys are generated, stored, and transmitted. Verify encryption, leakage protection, recovery mechanisms, and resistance to phishing and social engineering attacks.
Access control & authorization audit
We audit user permissions, multisig configurations, role models, and transaction confirmation logic. Validate protection against unauthorized access.
dApp & DeFi interaction testing
We assess how your wallet interacts with DeFi protocols, NFT marketplaces, and Web3 applications. Identify potential exploits and unsafe contract interactions.
UX & protection mechanism assessment
We review the user interface for misleading warnings, UI phishing vectors, and unsafe flows. Provide recommendations to improve security-oriented UX.
Audit report & recommendations
We deliver a full report outlining discovered vulnerabilities, risk severity, remediation priorities, and technical tasks for your development team.

Step 1 Architecture & wallet type reviewс архитектурой и типом кошелька
Collect information about wallet type (mobile, web, hardware, smart), cryptography, multisig usage, and dApp connections. Define audit scope, threat level, and asset criticality.
Time to deliver
~ 1-2 days
Step 2 Key storage & access analysis
Analyze encryption, storage, transmission, and recovery mechanisms. Review use of HSMs, hardware storage, or third-party SDKs. Assess MITM and compromise risks.
Time to deliver
~ 2-4 days
Step 3 Web3 interface & interaction testing
Perform manual and automated testing of Web3 APIs, permissions, popups, and event handling. Identify UX vulnerabilities and phishing scenarios.
Time to deliver
