The depth engagement teams graduate into before launch, listing, or major release. Senior auditors, AI-accelerated, with severity-ranked findings and re-audit verification included.
Talk to our teamOur audit practice
End-to-end audits for Solidity, Rust, Move, and Cairo code. Manual review of smart contracts, APIs, integrations, business logic, governance, and tokenomics.
Learn moreThreat modeling and adversarial testing for autonomous AI agents, tool-use, and agent-to-protocol surfaces.
Learn moreProperty-based and adversarial fuzz campaigns for Web3 code — AI-guided harness generation, human-validated findings.
Learn moreWhat you get
Every engagement follows the same disciplined methodology — manual review of business logic and protocol surfaces, AI-accelerated breadth across the codebase, and adversarial testing on critical paths.
Critical, high, medium, low and informational — calibrated to real-world exploitability.
Each finding ships with a minimal, verifiable reproduction your engineers can run.
Concrete fix recommendations, alternative designs, and code-level patches where appropriate.
After remediation, we re-verify the fixes and publish a clean final report.
