🔍 Pre-Audit Reviews

A pre-audit review is designed to prepare your project for a full audit. This early stage review identifies structural weaknesses and common pitfalls so you can streamline the official audit process — saving both time and cost.

🔒 Web3 Security Audits

A security audit is the cornerstone of trust in Web3. We conduct in-depth, end-to-end reviews of smart contracts, protocols, and blockchain infrastructure to detect vulnerabilities before they can be exploited.

🎯 Web3 Development

Security and functionality go hand in hand. Our development services help teams design and implement scalable, secure, and production-ready smart contracts and protocols.

🧪 Fuzzing & Advanced Testing

Fuzzing is one of the most effective ways to uncover edge-case vulnerabilities that traditional testing misses. We simulate adversarial inputs, unexpected states, and long-tail execution paths to stress-test protocols.
