Guardix is a smart contract security platform built for Solidity codebases running on EVM-compatible chains, including Ethereum, Arbitrum, Optimism, Base, and Polygon.

The platform runs a structured five-stage audit pipeline. It begins by pinning to a specific GitHub branch and commit, producing a reproducible snapshot of the code under review. From there, the system maps the full contract architecture: inheritance trees, call graphs, state transitions, and design invariants. This architectural layer is assembled before any vulnerability scanning takes place, and it becomes a core part of the final report, giving engineering teams visibility into how the system was understood, not just where issues were found.

Once architecture mapping is complete, multiple large language models independently analyze the codebase. Each model evaluates the code against 14 distinct vulnerability classes using structured, checklist-driven methods. The models operate in parallel and produce separate sets of findings. A consensus validation stage then filters these results: only issues where multiple models agree with high confidence are retained. This cross-validation step is designed to reduce false positives, which remain one of the biggest time sinks in automated security tooling.

For findings rated critical or high severity, the pipeline goes a step further. It generates proof-of-concept exploit code using Foundry and executes it against a forked version of the target chain. If the exploit succeeds, the finding is confirmed as real and exploitable. If the exploit fails, the finding is either downgraded in severity or removed from the report entirely. This verification layer gives teams a concrete, reproducible answer rather than a theoretical warning.

Each report is tied to the exact commit that was scanned and versioned automatically. When a team fixes issues and pushes new code, they can re-run the audit on the updated commit and compare results side by side. This makes it straightforward to track security posture across development cycles without re-engaging an external auditor for every change.

The platform supports the full range of common EVM deployment targets. A typical full pipeline run completes in one to three hours depending on codebase complexity, compared to weeks for traditional manual audits. Reports can be shared via direct link or exported as PDF for stakeholders, investors, or compliance documentation.

Guardix is positioned as a first line of defense for teams shipping Solidity contracts. It does not replace manual review for novel attack vectors or protocol-specific edge cases, but it covers broad vulnerability classes with a level of rigor that goes beyond what single-model scanners or static analysis tools typically deliver.
