Guardix is a smart contract security platform for Solidity codebases on EVM chains: Ethereum, Arbitrum, Optimism, Base, and Polygon.
The audit runs as a five-stage pipeline. It starts by pinning to a specific GitHub branch and commit, then maps the contract architecture: inheritance trees, call graphs, state transitions, and invariants. This happens before vulnerability analysis begins and becomes part of the final report.
Multiple LLMs then independently analyze the codebase against 14 vulnerability classes. Only findings where several models agree with high confidence survive to the report, which cuts down false positives significantly.
For critical findings, the platform generates proof-of-concept exploit code and runs it against a forked chain. If the exploit executes, the vulnerability is confirmed. If not, it gets downgraded or dropped.
Reports are versioned per commit. After fixes, teams can re-audit and compare results side by side. A full run typically takes one to three hours. The first audit is free, no credit card required.
