QuillShield

QuillShield stands out in the blockchain security ecosystem by turning the traditionally reactive audit model into a proactive, AI-led development companion. Built by the team behind QuillAudits, this tool is specifically engineered for smart contract developers who need continuous, real-time security support across every stage of the development cycle.

At its core, QuillShield is powered by an RL-based Adversarial Agent, a component designed to simulate the actions of a malicious actor. This means the tool doesn’t just scan for known vulnerabilities—it attacks your code like a hacker would, using real transaction sequences in a simulated environment to prove the existence of vulnerabilities. The result is a much deeper level of insight, revealing even complex and layered attack surfaces that traditional static analyzers might miss.

Beyond detection, QuillShield offers automated code repair, delivering AI-generated patches that address over 200 types of vulnerabilities. With an auto-fix rate of approximately 80%, this feature accelerates the remediation process and helps teams push secure code faster. The simulation sandbox provides the “proof” for each reported issue, making it easier to understand and verify bugs with contextual transaction data.

The product is developer-centric in its usability. Integration is seamless—developers can upload files, import verified smart contracts from supported chains, or directly link GitHub repositories. From there, the tool offers real-time security monitoring, generating customizable audit reports in minutes. These reports are professional-grade, shareable with stakeholders, and available in multiple templates for various use cases.

Unlike traditional one-time audits, QuillShield continues to monitor contracts even after deployment. Through its Adversarial ReScans, it automatically revisits deployed code to check for new types of threats that might have emerged in the ever-evolving Web3 security landscape. This persistent vigilance transforms audits from a snapshot into a continuous process.

Competitors in the space include tools like MythX, Consensys Diligence, and CertiK Skynet. However, most rely heavily on static or semi-static analysis, lacking the real-time adversarial attack simulations and automated repair capabilities that QuillShield brings to the table.

QuillShield offers a comprehensive suite of security features and developer tools that make it a game-changer in the Web3 audit space:

• AI-Powered Audits: Runs in under 5 minutes using reinforcement learning algorithms trained on thousands of audited contracts, ensuring high scan accuracy.
• Adversarial Agent Attacks: Simulates real-world hacks using transaction sequences, identifying vulnerabilities that basic scanners often overlook.
• Automated Code Repair: Fixes over 200 types of vulnerabilities using AI-generated code patches, achieving an estimated 80% auto-remediation success rate.
• Audit Reports in One Click: Offers 5+ report templates for professional-grade auditing documentation that’s shareable with teams or investors.
• Simulation Sandbox: Provides reproducible scenarios for each bug, so developers can see exactly how exploits could occur.
• GitHub & On-Chain Syncing: Integrates with GitHub for live codebase monitoring and supports contract analysis across 10+ blockchain networks.
• Adversarial ReScans: Monitors contracts continuously post-deployment, catching new threats and sending updated alerts.
• Trusted by Industry Leaders: Engineers from Taiko, ZetaChain, Metis, and Celo already use QuillShield for real-time defense.
