Smart Contract Audit

A Defense in Depth Security Assessment Built for Blockchain's High Stakes. In blockchain, there are no rollbacks. A single vulnerability can compromise millions in user funds and permanently damage reputations. From the DAO hack to today’s complex flash loan exploits, the message is clear: security is not optional, it’s existential. At CodesenSys, we deliver deep, adversarial audits that go beyond the checkbox. Our methodology is designed to fortify your smart contracts against known vulnerabilities and emergent threats, ensuring your project is trusted, resilient, and ready for scale.

One overlooked bug can collapse an entire protocol.

Why Smart Contract Audits Matter

A smart contract is immutable once deployed. Without proper validation, flaws in access control, logic, or integrations can become critical attack vectors.

We approach every audit as a strategic investment in the long term health of your protocol an essential milestone to protect assets, ensure compliance, and foster community confidence.

What Makes Our Audit Different?

Rigorous manual reviews by experienced blockchain security researchers
Automated static/dynamic analysis using industry-leading tools
Full Stack threat modeling including economic and governance layer risks
Post audit remediation support and verification

The CodesenSys Audit Lifecycle

A Multi Phased Process Designed for Maximum Threat Coverage. Our defense in depth audit strategy covers the full spectrum of vulnerabilities, from codelevel bugs to highlevel economic exploits .

Phase 1: Specification & Logic Alignment

Before we touch the code, we understand your intent. Our team reviews:
Whitepapers, protocol documentation, and architectural diagrams
Intended economic and governance mechanics
Functional specifications and technical assumptions

Phase 2: Automated Scanning & Fuzz Testing

We use powerful tools to simulate thousands of edge cases and flag risky patterns.
Our Toolkit Includes:
Static Analysis: Tools like Slither and MythX detect unsafe code structures and gas inefficiencies
Dynamic Analysis & Fuzzing: Echidna and Foundry run randomized and adversarial inputs to break core assumptions

Phase 3: Manual Review by Security Experts

Our senior auditors perform a meticulous, line-by-line review of your smart contracts, evaluating:
Complex logic and invariants
Protocol specific economic and game theoretic vulnerabilities
DeFi risks such as flash loan reentrancy and oracle manipulation

Phase 4: Transparent Reporting & Fix Validation

You receive a comprehensive, easy-to-share security report that includes:
Executive summary for investors and stakeholders
Severity ranked vulnerabilities with technical explanations
Realistic exploit scenarios and remediation guidance
Follow-up review to verify patch quality and integrity

What We Secure You Against

We follow leading industry standards including the OWASP Smart Contract Top 10, and beyond. Common Vulnerabilities We Catch and Eliminate

Reentrancy Attacks

Recursive exploits used to drain funds before state updates complete.

Access Control Flaws

Unauthorized privilege escalations like minting or admin takeovers.

Integer Overflow/Underflow

Arithmetic anomalies that distort balances or supply caps.

Oracle Manipulation

Injecting fake data to trigger faulty liquidations or rewards.

Business Logic Errors

Misalignments between code and protocol intent that create unfair advantages or economic leakage.

The Outcome

Audit as a Competitive Edge

A CodesenSys Audit Report Is More Than a Pass/Fail Sheet

It’s a security asset you can publish, reference in listings, and use in due diligence processes. It proves your commitment to trust, transparency, and operational excellence.

Attract institutional capital with verified security readiness
Boost user confidence with transparent audit results
Streamline exchange and partner onboarding with security compliance
