    Agentic Smart
    Contract Auditing

    Cecuro delivers deep, rigorous smart contract audits through proprietary AI agents that run for hours across your entire codebase — catching vulnerabilities that human auditors and frontier models often miss.

    Top-tier audits for every builder

    Every project deserves the same protection as billion-dollar protocols.
    The same rigor that protects major DeFi, now within reach.

    Depth You Can Trust

    Our AI agents typically run for 8+ hours per audit, systematically exploring attack vectors and edge cases that human auditors, constrained by time and cost, routinely miss.

    No Tradeoff Between Depth and Speed

    Traditional audits take weeks because thorough human analysis is slow. Our agents achieve the same depth in hours, with no queues and no compromises.

    Security for Every Builder

    Top-tier audit quality that was previously reserved for protocols with six-figure security budgets, now accessible to every Web3 project.

    Missed finding
    • Medium

      Medium finding pending public disclosure

      Cecuro identified a Medium-severity vulnerability in a Solidity merkle-tree verification path that was reviewed and missed by SRLabs's May 2026 audit. Full technical writeup and the named project will be published once the issue is fixed and disclosure is appropriate.

    Missed finding
    • Low

      Low-severity finding missed across the V3 competition and review

      Cecuro identified a Low-severity vulnerability in Alchemix V3 that was reviewed and missed by both the Immunefi competition (298 researchers, 952 reports, $100k pool) and a subsequent Y-Audit review (commit 45e4b08).

    How Y-Audit touched this code

    Confirmed at commit 45e4b08.

    2 missed findings
    • High

      First High finding pending public disclosure

      Cecuro identified a High-severity vulnerability reviewed and missed by Hacken's January 2026 audit. Full technical writeup and the named project will be published once the issue is fixed and disclosure is appropriate.

    • High

      Second High finding pending public disclosure

      Cecuro identified a second High-severity vulnerability reviewed and missed by Hacken's January 2026 audit. Full technical writeup and the named project will be published once the issue is fixed and disclosure is appropriate.

    Missed finding
    • Critical

      Cross-function reentrancy in ServiceManager.create() drains pooled ERC20 deposits via _safeMint callback

      ServiceManager.create() registers a new service and mints its ownership NFT via ERC721 _safeMint, which hands control to the recipient's onERC721Received hook before the service's accounting is finalised. From inside that callback an attacker can re-enter the registry's deposit path and act against pooled ERC20 deposits while the contract's state is still mid-update — a classic cross-function reentrancy across the create/deposit boundary. Reviewed and missed by the Zellic V12 AI auditor, which inspected ServiceManager.create() and StakingBase but did not flag the _safeMint reentrancy window.

    How Zellic V12 touched this code

    Reviewed ServiceManager.create() and StakingBase, but did not flag the _safeMint reentrancy window.

      High finding pending public disclosure

      Cecuro identified a High-severity vulnerability that was reviewed and missed by four independent audits — Cantina Code, GetRecon, 0xMacro, and Octane Security. Full technical writeup and the named project will be published once the issue is fixed and disclosure is appropriate.

    INSIDE THE ENGINE

    Rigorous by design. Not another scanner.

    Most tools surface-scan your code in seconds. A Cecuro audit coordinates ~180 specialized agents for an average of 8 hours, investigates every contract from adversarial angles, and reproduces each finding with a runnable proof-of-concept before it reaches your report.

    How It Works

    Getting started is simple. Connect your code and receive a comprehensive smart contract audit in just a few hours.

    Step 1

    Connect GitHub

    Select your repository, branch, and commit, then submit for auditing.

    60 seconds to start
    Step 2

    Deep Agent Analysis

    Our AI agents spend ~8 hours systematically probing attack vectors, tracing execution paths, and testing exploit scenarios across your entire codebase.

    Tested on 90 real exploits that caused $228M in losses. Both systems ran the same frontier model. The difference is entirely Cecuro's purpose-built security architecture.

    About These Benchmarks

    EVMBench results from the industry benchmark by OpenAI, Paradigm, and OtterSec. Real-world exploit data sourced from Anthropic's SCONE-bench and DeFiHackLabs. Both confirm that specialized architecture, not model size, is the key differentiator in AI smart contract security.

    "Cecuro caught real issues that were independently confirmed by our human senior auditors. The findings were well-reasoned, clearly explained, and actionable. For an AI-powered audit, the signal-to-noise ratio was impressive. We came away with genuine improvements to our codebase and will definitely be using Cecuro on future codebases."

    Utkir

    CTO at Zyfai

    "We ran Cecuro alongside our existing audit process and it flagged a critical finding that separate manual reviews had missed. Saved us from what could have been a serious incident."
