COMPREHENSIVE ANALYSIS
What Our Security Audit Covers
Our dApp frontend audit is a systematic review of your entire user-facing application, identifying vulnerabilities that could lead to fund loss, data breaches, or degraded user trust. We go beyond automated scanners with manual expert analysis.
02
Client-Side Logic & State Management
Manual review of React/Vue state handling, hook dependencies, and data flow to eliminate race conditions, state corruption, and logic flaws that could compromise transaction integrity or user data.
04
Dependency & Supply Chain Review
We audit third-party libraries (web3.js, ethers, Wagmi), browser extensions, and npm packages for known vulnerabilities, malicious code, and version compatibility issues.
05
UI/UX & Phishing Resistance
Evaluation of transaction confirmation modals, address display formats, and copy-trading safeguards. We identify design patterns vulnerable to address poisoning, fake token approvals, and imitation attacks.
06
Compliance & Data Privacy
Review of data collection, storage, and transmission practices for GDPR/CCPA compliance. We ensure no sensitive keys or PII are exposed in logs, local storage, or analytics.

THE DIFFERENCE
Why a Specialized Frontend Audit is Critical
Generic security scans miss the unique attack vectors of Web3 applications. Our targeted audits uncover vulnerabilities that directly threaten user assets and protocol integrity.
01
Wallet & Transaction Security
We audit for critical flaws in wallet connection logic, transaction signing flows, and private key exposure that could lead to direct fund loss. Our review includes simulation of malicious contract interactions.

02
Smart Contract Integration
We validate the security of your frontend's interaction with smart contracts, checking for ABI mismatches, state synchronization errors, and reentrancy risks at the UI layer.
