Our audit process

We tailor our audits to your project’s needs

1

Scoping & Planning

We define the engagement scope, timeline, and key focus areas based on your project’s requirements.

2

Research & Analysis

Our team studies the architecture, documentation, and technical details to fully understand the system.

3

In-Depth Review

We conduct a thorough security assessment, identifying vulnerabilities, inefficiencies, and risks.

4

Validation

Using automated and manual techniques, we validate the system under real-world conditions.

5

Reporting & Recommendations

We deliver clear findings with actionable steps to enhance security and performance.

What is a Blockchain L1 & L2 Protocol Audit?

A Blockchain L1 & L2 Protocol Audit assesses the security and economic integrity of Layer 1 and Layer 2 solutions. Unlike smart contracts, blockchains govern consensus, transaction validation, and network incentives—making their security critical. Our audits evaluate validator mechanisms, tokenomics, governance structures, and cryptographic integrity to ensure a robust and attack-resistant blockchain infrastructure.

Why is a Blockchain L1 & L2 Protocol Audit Important?

  • Security - Prevents hacks and exploits.
  • Trust - Increases confidence for investors and users.
  • Compliance - Helps meet regulatory requirements.
  • Cost Savings - Fixing issues before deployment avoids costly security breaches.

Frequent answers and questions

Check out the Blockchain L1 & L2 Protocol Audits F.A.Q.

Why do Layer 1 and Layer 2 blockchains need audits?

Because they govern transaction validation, consensus, and economic incentives, which are common attack vectors.

How does an L1/L2 audit improve consensus security?

By analyzing validator integrity, chain reorg resistance, and Sybil attack prevention.

What are the most common vulnerabilities in blockchain protocols?

Consensus failures, economic exploits, governance attacks, and cryptographic weaknesses.

How do tokenomics affect blockchain security?

Poorly designed incentives can lead to chain instability, validator bribery, and network congestion.

What makes a Layer 2 solution secure?

Proper fraud proofs, dispute resolution mechanisms, and robust bridge security.
