Find vulnerabilities before attackers do.
AI-powered audits that map your architecture, validate findings across multiple models, and verify exploitability — not just flag patterns. First audit free.

Validated findings
Every finding comes with code, context, and multi-model confidence.
Findings include severity, file location, Solidity code snippets, and validation confidence from multiple models. Not vague descriptions — actionable signals.
Unchecked external callback before balance update
The withdraw function calls an external contract before updating internal state, enabling reentrant calls to drain funds.
function withdraw(uint256 amount) external {
require(balances[msg.sender] >= amount);
// ⚠ external call before state update
token.transfer(msg.sender, amount);
balances[msg.sender] -= amount;

Exploit pipeline
Findings backed by proof-of-concept exploits.
Critical findings are verified against a forked chain. If the exploit executes, you know it's real — not a false positive. Automated, reproducible, and verifiable.
Architecture context
Invariants, assumptions, and decisions — not just a list of bugs.
The audit maps the system architecture before looking for issues. Findings are grounded in what the contracts are supposed to do, not just what they technically allow.
Total supply must equal sum of individual balances at all times
Threat if broken
Direct loss of depositor funds
Queue state transitions must be monotonic: pending → processing → done
Threat if broken
Double-processing of withdrawals
Oracle price feeds assumed fresh within 1-hour staleness window
Threat if broken
Incorrect liquidation at stale prices
Admin role changes cannot bypass timelock constraints
Threat if broken
Unauthorized privilege escalation
How it works
From pinned commit to a report you can defend.
One reproducible snapshot in; architecture context, tightened findings, and proof where severity demands it. Select a stage to read what happens there.
When a pipeline step is focused, use arrow keys to move between stages. Home and End jump to the first or last stage.
Stage 01
Pin your snapshot
Lock to the exact branch and commit you plan to ship.
Positioning
First line of defense. Not a replacement.
Guardix maps your architecture, runs broad parallel analysis with multiple independent models, and verifies critical findings with exploit proof of concepts. Use the remaining budget for novel attack vectors that require human judgment.
