A STRUCTURED APPROACH
Our Methodology for Storage Security
Our assessment follows a rigorous, multi-layered methodology designed to uncover critical vulnerabilities and provide actionable, developer-ready fixes. We focus on the unique attack vectors of CosmWasm's storage layer.
03
Manual Code Review & Exploit Simulation
Our security engineers conduct line-by-line manual review of all storage logic, simulating complex attack scenarios to uncover logic errors, privilege escalation, and cross-contract interaction risks.
04
Gas Optimization Analysis
We profile your contract's storage read/write operations to identify and remediate gas inefficiencies, reducing operational costs and improving user experience for high-frequency transactions.
05
Comprehensive Reporting & Remediation
You receive a prioritized report with CVE-style vulnerability descriptions, exploit proof-of-concepts, and direct, copy-paste code fixes for every issue found, categorized by severity (Critical, High, Medium, Low).
06
Post-Audit Support & Verification
We provide a follow-up review of your fixes to ensure vulnerabilities are correctly patched, offering guidance on secure development practices to prevent future issues in your storage layer.

Frequently Asked Questions
Get clear answers about our specialized security assessment process for CosmWasm storage modules.
Our standard assessment is a 2-week engagement for a single, well-defined storage module. We deliver a comprehensive report covering access control, state mutation logic, gas optimization, and integration risks. For complex protocols with multiple interdependent modules, timelines scale to 3-4 weeks. We provide a fixed-price quote after a 1-hour technical scoping call.
