Smart contract audits aim to uncover security flaws such as source code defects, vulnerable dependencies, and logical loopholes in smart contracts. ScienceSoft provides automated code analysis, manual code review, vulnerability assessment, and penetration testing services to assess the security of smart contracts and Web3 apps and provide straightforward remediation guidance.
Auditing Diverse Solutions That Utilize Smart Contracts
Decentralized applications (dApps)
- Crypto wallets.
- Web3 games.
- Metaverse apps.
- Other applications running on a blockchain or P2P network.
- Tokenized assets: asset-backed tokens like utility tokens, security tokens, governance tokens, or NFTs.
- Asset tokenization platforms: ICO, STO, and other platforms for token issuance and exchange.
Blockchain-based market platforms
- Decentralized ecommerce marketplaces.
- NFT marketplaces.
- DeFi lending platforms.
- Crypto exchange platforms.
Decentralized autonomous organizations (DAOs)
- For collaborative decision-making across communities.
- For corporate governance in organizations with no central authority.
Smart Contract Types We Cover
Transactional smart contracts
Facilitating various payments, lending and trading transactions, and transfer of responsibility and ownership.
Asset management smart contracts
Handling token issuance, distribution, and ownership transfer.
Security smart contracts
Enforcing fraud detection, KYC/AML verification, and compliance checks for regulated industries like insurance, financial services, and healthcare.

Smart Contract Security Audit: How It Works
ScienceSoft applies a tailored approach to auditing smart contracts depending on each unique case and application. Below, we outline a general plan for an end-to-end audit.
1.
First contact & planning
-
You send us a request.
-
Our team member contacts you within 24 hours to arrange a discussion of your case.
-
We can sign an NDA before the introductory call to ensure legal protection of your confidential information.
-
We carefully investigate your security needs and prepare a proposal that specifies the audit scope, techniques, plan, team composition, timelines, and estimated costs.
-
After signing a service contract, we assemble an audit team and start the project within one week.

2.
Preparation
Our audit team gathers and carefully reviews the documentation (e.g., smart contract specifications, source code, architecture diagrams). This helps us identify the technologies used (languages, blockchain frameworks and networks), deployment instructions, and functional and non-functional requirements, including integrations with other solution components.
For a more time- and cost-effective audit, we recommend keeping source code documentation up to date and pausing code changes until the audit is complete. These measures ensure an undistorted understanding of the software's current state and help avoid unnecessary retests.
3.
Execution
- The auditors conduct automated checks using static and dynamic application security testing (SAST and DAST) tools and validate the findings to exclude false positives.
- By performing a manual review, our experts reveal more complex issues, such as discrepancies between the specification and the implementation, flaws in automated compliance checks, misconfigurations, and interoperability issues.
- During the security audit, we apply proven testing and classification guidelines, including:
- Smart Contract Weakness Classification Registry (SWC)
- EEA EthTrust Security Levels Specification
- OWASP Smart Contract Top 10
- NIST SP 800-115
- We examine smart contracts against established security recommendations and best practices, for example:
- Ethereum Smart Contract Security Guidelines
- Smart Contract Security Field Guide
- Solidity Security Considerations
- Solidity Style Guide
- If required, our Certified Ethical Hackers are ready to conduct complementary penetration testing of the Web3 apps interacting with the smart contract. For example, our pentesters detect poor input handling and other app vulnerabilities that can cause the smart contract to behave in unexpected ways (e.g., execute unauthorized transactions or leak sensitive information).

Reporting
The team reviews the audit results and draws up an actionable report containing:
-
A project summary (audit scope, audit methods, frameworks, etc.).
-
Audit findings (a clear description of the found security issues classified by their severity and the risks they present).
-
Step-by-step recommendations on how to fix the identified vulnerabilities.
-
A conclusion on the smart contract's readiness for deployment.

Reasons Why You May Need a Smart Contract Audit
$3.1 million on average was lost in a smart contract security breach in Q1 2024.
Secure coding practices and comprehensive pre-deployment security reviews significantly reduce the attack surface and mitigate the risk of asset loss and sensitive data disclosure. Compare the potential financial impact of a security breach to audit costs: smart contract security audit services may cost from $5,000 to $50,000, depending on the scope and complexity of the audit targets.
Examples of vulnerabilities we detect
Examples of attacks a smart contract audit can help protect against
The latest best practice to mitigate blockchain security risks is to implement security measures on the contract code level:
- Pause function.
- Allowlisting function.
- Rate limiting, particularly withdrawal rate limiting.
- Functions to modify asset price feeds and limits on asset supply or borrows in case of a security event.
Choose Your Service Option
Automated audit
We examine a smart contract using automated tools to detect and validate coding errors.
Key benefit: The fastest and most cost-effective option.
Automated and manual audit
We scrutinize a smart contract for coding errors and issues related to business logic and interoperability with other contracts and external systems.
Key benefit: Cost- and time-effectiveness balanced with exploration depth.
Audit and pentesting
In addition to a smart contract audit (manual, automated, or combined), we identify potential entryways in your Web3 apps and external systems that could allow unauthorized access to the smart contract.
Key benefit: The most exhaustive exploration and evaluation of potential impact.
