Most “smart contract hacks” start as integration failures: frontend constructs a bad tx, backend trusts a client field, or contracts assume off-chain checks happened. We audit the whole execution chain.
Frontend transaction construction and validation
Wallet signing UX and simulation/preview flows
Backend APIs and access control
Contract interaction boundaries and assumptions
Cross-contract calls and router behavior
Logging, analytics, and sensitive data exposure
user → UI → wallet → API → chain
where validation is assumed, not enforced
manipulate each boundary systematically
prove fund-loss or control-loss paths
fixes that close entire chains, not symptoms
Integration breakpoints with proof and impact
Fix direction that moves checks to the right layer
Regression test ideas for the flow
Retest confirmation
Frequently Asked Questions
We audit the full stack: frontend (wallet connections, transaction building), backend (APIs, databases), and smart contracts (on-chain logic). Most dApp hacks exploit integration seams—we test those.
Smart contract audits don't cover frontend phishing, API authorization gaps, or database injection. dApps fail when the web2 and web3 layers don't connect securely.
Frontend: Wallet integration, transaction signing flows, user input validation, XSS/CSRF protection. Backend: API authorization, database security, session management. Smart contracts: On-chain logic and integration assumption
Yes—we test the entire attack surface. Most exploits target the weakest layer, which is often the frontend or API, not the smart contract.
We simulate malicious dApps trying to trick users into signing bad transactions, phishing for unlimited token approvals, or front-running user actions. Wallet connections must be secure and transparent.
Simple dApp: 2–3 weeks. Complex platform: 3–5 weeks. Depends on feature count and integration complexity.
