Contract audits check the chain. They don't check the swap flow, the approval that over-permits, the WebSocket price feed that lies under load, or the API endpoint that lets anyone bypass your limits. I do. Before your users find out the hard way.
Most exploits that reach users aren't broken Solidity. They're broken flows, sloppy approvals, and infrastructure that falls apart the moment real traffic hits it. That's the layer between your contract and your user — and it's usually shipped untested.
The frontend asks for unlimited allowance when it needs an exact amount. One compromised contract later, wallets drain.
Header spoofing, param tampering, missing auth on a single endpoint — the bypass that lets one actor abuse the whole platform.
Your price WebSocket is perfect with one client and desynced with two hundred. Users trade on stale numbers. You eat the difference.
Network switch mid-session, the sign prompt still points at the old chain. Best case, confusion. Worst case, a transaction on the wrong network.
You know the cost before we start. Every audit ships a severity-graded report with reproduction steps, and the automated tests are yours to keep.
You send the app link and a short brief on where the money moves. I reply with the exact surface I'll test — which flows, endpoints and feeds — and a fixed price. All in writing, so scope is locked before we start.
I map every path a user's funds can take and every request the app makes. This is where most of the dangerous gaps first show up.
Endpoint tampering, approval inspection, wrong-chain checks, then concurrency and load on the parts that break quietly at scale.
Each finding: severity, impact in plain terms, exact reproduction steps. Not a wall of noise — a prioritized list of what to fix first.
I build and break high-concurrency systems for a living — Selenium & Playwright automation, API testing, WebSocket data pipelines, and load testing where thousands of events per second is normal. I run my own trading infrastructure across ten chains, so on-chain flows, wallet interactions and exchange APIs aren't theory to me — they're the thing I debug every day. Loadfault points that toolkit at your product.
Start with a free smoke test on one critical flow. If it's clean, you get peace of mind. If it isn't, you just avoided a very expensive week.
