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 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.

Traceability smart contracts

Ensuring traceability across supply chain, logistics, and document management processes.

Decision-making smart contracts

Enabling secure and incorruptible decision-making mechanisms, such as e-voting systems.

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.


First contact & planning

How we start:

  • 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.





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.

  • 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).




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.



Technologies & Tools We Use

Reasons Why You May Need a Smart Contract Audit

Smart contracts are the primary attack vector in applications that use blockchain.

(2023 Gartner)

$1.7 billion stolen from crypto projects across 231 hacking incidents in 2023.

(2024 Chainalysis)

$3.1 million on average was lost in a smart contract security breach in Q1 2024.

(2024 Footprint and Beosin)

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

Head of Web3 Development, ScienceSoft

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.
