We communicate and collaborate with you in every stage to ensure both business and code objectives are achieved securely and efficiently.
Team Structure
- 2+ Blockchain Security Researchers
- Technical Manager
- Project Manager
The team is supported by Cryptographers, Advanced Testing Engineers, and Security Analysts based on project requirements.
Pre-Audit
Our security researchers prepare in advance by reviewing your project documentation, running test suites, and analyzing codebase architecture. A dedicated technical manager consults with you on technical details to optimize audit readiness.
An initial assessment by our proprietary vulnerability scanner helps focus our team's efforts on identifying the most critical vulnerabilities.

We conduct a comprehensive review of your system's architecture and codebase, with each line of code inspected by at least two security researchers. We adopt a collaborative approach, engaging directly with developers throughout the audit.
When necessary, our researchers employ advanced testing techniques, including fuzzing and invariant testing, to ensure system integrity.
Fix Review
The fix review process is as important as the audit itself. Our security researchers meticulously review fixed issues and engage with developers to discuss the nuances of your codebase.
Upon review, the final audit report is delivered, allowing your team to track issues and resolutions with direct auditor communication.
Ongoing Partnership
Once we've audited your project, we become experts in your code. We maintain an open communication channel for any future consultation needs.
Our security audits often result in long-term collaborative relationships, providing continuous security assurance as your project evolves.

Smart Contract Audit FAQ
Pricing depends on the size and complexity of your codebase. A typical audit for a small to medium DeFi protocol ranges from $15K to $50K, while larger or more complex projects can go higher. We provide detailed quotes after reviewing your code. Reach out and we'll give you a clear estimate.
Most audits take 1-3 weeks depending on lines of code and protocol complexity. Simple token contracts might be done in a week, while a full DeFi protocol with multiple integrations could take 3+ weeks. We can also accommodate rush timelines when needed.
We check for over 100 vulnerability types including reentrancy attacks, integer overflow/underflow, access control issues, flash loan exploits, price oracle manipulation, front-running, and business logic flaws. Our team also reviews your economic model for potential attack vectors.
Yes. Every audit includes one round of fix verification at no extra cost. After you address the findings, we'll review the changes and issue an updated report confirming the fixes.
We audit Solidity, Vyper, Rust (for Solana and CosmWasm), Move (Sui and Aptos), Cairo (Starknet), and Ink! (Polkadot). We support Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Base, Solana, Sui, and most EVM-compatible chains.
