Static analysis
Slither, Mythril and Semgrep sweep the known vulnerability patterns first.
TECH & SECURITY
Security Audit
Contract & System Security Audit
Everything we list or deliver goes through the same process: automated scanning for surface, manual review for logic, penetration testing for exploitability. Finding nothing is not the same as nothing being there — so the report states every conclusion, reproduction step and fix, along with exactly what was and was not in scope.

What You Get
Fuzzing
Foundry and Echidna property tests surface edge cases and invariant violations.
Manual review
Line-by-line review of the business logic, focused on permissions, economics and external calls.
Exploitation
Reentrancy, flash loans, price manipulation and privilege escalation, each tested for real exploitability.
Backdoor detection
Hidden owners, proxy implementation addresses, malicious dependencies and obfuscated code all get pulled apart.
Report
Findings ranked Critical through Info with reproduction and fixes, plus one free re-review after remediation.
How It Works
Freeze scope
Agree the scope and commit hash; the code stays frozen for the duration.
Review
Tools run first, then every warning and the business logic get a manual pass.
Report
Draft the report and walk through impact and priority with your developers.
Re-review
Re-review after the fixes, then issue the final report.

When to Use It
Before mainnet
The contracts are about to deploy and need an independent third-party check.
Inherited code
You are acquiring or taking over someone else's code and want due diligence before committing.
Post-incident
Something has already happened and you need root cause, blast radius and hardening.
FAQ
QDoes passing mean it is safe?
No. An audit reduces risk without eliminating it, and the report states the scope, the assumptions and what was left out.
QDo you disclose critical findings?
No. We notify you privately and only issue the formal report once the fix is in and verified.
QHow fast?
Five to seven business days as standard; large codebases or rush jobs are scheduled separately.
QAudit only?
Yes — the audit is a standalone service with no development attached.
