The working PoC exploited it on first run against a mainnet fork. This tool has become essential in our audit stack."* > — **Security Researcher, Web3 Audit Firm** > *"The 23-agent parallel architecture is a game changer. Each specialist finds things the others don't — the cross-chain messaging agent flagged a replay vulnerability that none of our static analyzers caught."* > — **Lead Auditor, DeFi Security Team** --- ## 📄 License MIT © 2026 Iktok Security Labs — Zug, Switzerland > **Disclaimer:** AuditSentry is a security research tool.
