The tool analyzes Solidity, Vyper, and Rust contracts in under 60 seconds, categorizing vulnerabilities by severity and providing fix explanations. It offers free trials with no signup required.", "body_md": "If you were using MythX before March 31st, you already know.\n\nConsenSys quietly sunset the entire MythX suite. One day it was there, the next your CI pipeline was just... failing silently. They pointed people toward Diligence Fuzzing, which is a great property-testing tool but it's not an audit tool. Writing fuzz harnesses isn't the same as pasting a contract and getting a vulnerability report back.\n\nI've been building in Web3 security tooling for a while, and I kept running into the same wall: traditional audits cost $10K–$150K and take weeks, open-source scanners like Slither are powerful but raw, and the affordable SaaS middle ground basically disappeared when MythX went dark.\n\nSo I spent several months building SmartContractAuditor.ai an AI-powered audit tool that fills that gap.\n\nWhat it does:\n\nPaste your Solidity, Vyper, or Rust contract and get a categorized report in under 60 seconds\n\nFindings are split into Critical / High / Medium / Low severity\n\nEach finding includes a plain-English explanation of why it's dangerous and how to fix it (not just \"SWC-107 detected\" with a link to a spec)\n\nFix verification apply the fix, re-paste, confirm it's gone\n\nPDF report export for sharing with your team or investors\n\nIt catches the stuff that causes real losses reentrancy, access control issues, oracle manipulation patterns, flash loan attack surfaces, tx.origin misuse, signature replay, unchecked external calls.\n\nIt's free to try 3 scans, no signup required. Just go to the site and paste a contract.\n\nI'm not posting this as a finished, polished product launch. I'm posting because I want feedback from people who actually write smart contracts.\n\nSpecifically:\n\nWhat does the output miss that Slither/Mythril would catch?\n\nIs the severity categorization reasonable, or is it over/under-flagging?\n\nWhat would make this actually fit into your dev workflow?\n\nIs there a specific vulnerability class you'd want it to prioritize?\n\nIf you've been looking for something to replace MythX in your pipeline, give it a shot and tell me what you think either in the comments here or on the site itself.\n\nThe tool is at smartcontractauditor.ai no account needed for the first 3 scans.", "url": "https://wpnews.pro/news/mythx-shut-down-in-march-and-nothing-replaced-it-so-i-built-something", "canonical_source": "https://dev.to/ninjafromqueens/mythx-shut-down-in-march-and-nothing-replaced-it-so-i-built-something-2ccp", "published_at": "2026-07-23 21:52:57+00:00", "updated_at": "2026-07-23 22:33:51.476113+00:00", "lang": "en", "topics": ["artificial-intelligence", "developer-tools", "ai-products"], "entities": ["ConsenSys", "MythX", "SmartContractAuditor.ai", "Diligence Fuzzing", "Slither", "Mythril"], "alternates": {"html": "https://wpnews.pro/news/mythx-shut-down-in-march-and-nothing-replaced-it-so-i-built-something", "markdown": "https://wpnews.pro/news/mythx-shut-down-in-march-and-nothing-replaced-it-so-i-built-something.md", "text": "https://wpnews.pro/news/mythx-shut-down-in-march-and-nothing-replaced-it-so-i-built-something.txt", "jsonld": "https://wpnews.pro/news/mythx-shut-down-in-march-and-nothing-replaced-it-so-i-built-something.jsonld"}}
