Challenges we solve

Every smart contract project faces critical hurdles on the path to launch. We review the code and provide comprehensive solutions to your biggest risks.

Costly vulnerabilities

Our expert team identifies issues such as reentrancy attacks, logic errors, integer over-/underflows, and flawed access controls before the contract is deployed. Your project will securely protect your users’ money.

Complex logic

Your team is skilled, but complex DeFi logic has edge cases. Our auditors provide an expert, unbiased second (or third) opinion. Our team of specialized security engineers think like attackers, they know what to look for.

Lack of users’ trust

Attract more users and investors with audited projects. Build legitimacy and trust by providing a publicly verifiable report that proves the code has been professionally scrutinized.

Reputation hazards

A single exploit can destroy a project permanently. Our rigorous process is your best defense, protecting the long-term brand value and community loyalty you're working to build.

Subjective perspective

Internal reviews are vital, but they can miss blind spots. Our specialized security engineers provide the critical, unbiased assessment needed to ensure no stone is left unturned.

Compliance concerns

We provide your projects with due diligence. You demonstrate to your clients that you took reasonable, industry-standard steps to secure their funds, which is crucial for legal and community relations.

Our Ethereum smart contract audit services

We support you on your way to a tailored Ethereum smart contract that optimizes your workflows and boosts revenue.

Smart contract audit

We conduct a multi-layered examination of your code to uncover critical vulnerabilities. Our smart contract audit services include PixelPlex audit frameworks with manual review with advanced tools. We deliver a detailed report of risks and their remediation.

Code analysis and review

Our experts inspect your smart contract line-by-line. We enhance code quality, maintainability, and adherence to Ethereum development best practices. We turn your codebase into a robust and well-documented asset.

Gas usage optimization

We analyze your contract's gas consumption to identify and eliminate cost inefficiencies. Following our recommendations, you will reduce transaction fees for your users and improve the affordability and competitiveness of your dApps.

We employ mathematical modeling and property-based testing to validate your contract's core logic. This process proves that your protocol behaves as intended under all conditions, removing the risks of unpredictable behavior before launch.

Security architecture review

We assess your entire dApp's design to uncover systemic and structural risks that might appear beyond the smart contract development itself. This provides you with a holistic threat model and practical strategies to fortify your application's foundational security.

Post-audit support

Our partnership continues after the report is delivered. We provide clear guidance on addressing the findings and are available to review your fixes, ensuring vulnerabilities are resolved correctly and efficiently.

Audit-ready Ethereum solutions for every project stage

We secure Ethereum-based ecosystems to help you build resilient infrastructure and mitigate risks inherent to the Ethereum blockchain and its smart contract environment.

DeFi applications

Our audits for DeFi protocols verify that complex financial logic executes as designed and user funds are protected. We conduct in-depth reviews of smart contract interactions and token flow to ensure economic security.

Key benefits of PixelPlex Ethereum smart contract audit provider

Security and financial protection

Make sure you prevent the loss of user funds due to exploits, hacks, and vulnerabilities. The costs of smart contract audit are far cheaper than the multi-million dollar losses common in the space.

Enhanced trust

An audit report from a reputable firm like PixelPlex acts as a stamp of approval. It signals to users, investors, and the community that the team takes security seriously.

Improved code quality

Our expert auditors find flaws and provide recommendations. They suggest optimization ideas for making contract functions cheaper to execute and make sure your code adheres to established Ethereum standards.

User confidence

With a carefully audited project, it is easier to attract investors. Besides, users are more likely to lock significant funds in a protocol that has been professionally reviewed. This is essential for bootstrapping liquidity and community.

Long-term viability

Finding and fixing critical bugs before launch prevents a catastrophic failure that could kill the project permanently. A single major hack often destroys a project's reputation irreparably.

Detailed reports

We provide our clients with vulnerability reports that clearly summarize the details of flaws and mitigation methods.

Most Common Smart Contract Vulnerabilities and How to Prevent Them

What does an Ethereum smart contract security audit include?

An audit is usually a multi-layered security review. It includes automated scanning for known vulnerabilities, in-depth manual code review by our security experts, an analysis of the business logic for flaws, a gas optimization review to reduce fees, and a final report detailing all findings and remediation steps.

How long does it take to audit a smart contract?

The timeline depends on the complexity and size of your codebase. We can audit a simple token contract in 3 to 5 business days. A complex DeFi protocol with multiple integrated contracts can take up to 4 weeks. We provide a firm timeline after the initial scoping call.

What if I skip a smart contract audit for my project?

While smart contract audit is not mandatory, skipping it is an extremely high-risk gamble. Without an audit, your project becomes vulnerable to exploits that could lead to the irreversible loss of user funds, complete collapse of your protocol, and permanent damage to your reputation. An audit is a standard practice for any project that handles value.

What vulnerabilities can a smart contract audit identify?

Our audits are designed to uncover a wide range of critical security flaws, such as reentrancy attacks, logic errors, access control issues, integer overflows and underflows, gas inefficiencies, and others.

Can you audit a contract that is already deployed on mainnet?

Absolutely. We can perform a post-deployment audit to identify vulnerabilities and provide a remediation plan. If we find a critical flaw, we will guide you through the necessary steps, which may include a contract migration.

What do you need to start the audit?

At PixelPlex, we require our client’s complete smart contract source code with any relevant technical documentation or whitepaper. We also refer to a description of the intended business logic and functionality, and look through the test suites you've already run.
