Astra's 7-Step Pentest Process

How our blockchain security audit services work

Learn how our team delivers smarter protection through expert-led blockchain vulnerability assessments and audits.

Discovery & Scoping

  • Identify all in-scope smart contracts, decentralized applications (dApps), nodes, APIs, and integrations for testing.
  • Define parameters, environments, and blockchain networks (Ethereum, BSC, Polygon, Solana, etc.) to ensure complete coverage.
  • Align the assessment scope with relevant compliance and security frameworks such as SOC 2, ISO 27001, or GDPR.
  • Personalized setup to maintain visibility throughout the engagement.


Outcome: Outline a mutually agreed compliance-guaranteed scope and a clear roadmap to blockchain audit readiness.

Authentication Setup

  • Establish secure authentication workflows for dApp testing across multiple wallet roles, private keys, and API endpoints.
  • Integrate credentials, tokens, and node access configurations to enable deep authenticated coverage.
  • Ensure safe testing within testnets or production replicas without disrupting on-chain operations.
  • Standardized authentication templates for future audits to streamline recurring security assessments.

Outcome: Get full-depth testing coverage of smart contracts and nodes without risking network continuity.

Automated Baseline

  • Run automated scans across smart contracts, APIs, and dApp components to detect reentrancy, overflow, underflow, logic flaws, and misconfigurations.
  • Leverage Astra Security’s tuned detection engine built for blockchain ecosystems to ensure comprehensive baseline coverage with minimized false positives.
  • Correlate automated findings with prior assessments to maintain historical visibility and improve audit readiness.
  • Deliver continuous monitoring data supporting ongoing blockchain compliance and risk management.

Outcome: Gain a comprehensive, continuous threat baseline ready for immediate on-chain action and reporting.

Checking reported Vulnerabilities

Manual Audit & Risk Scoring

  • Our experts manually validate automated findings, exploit potential logic flaws, simulate attack vectors (reentrancy, flash loan, oracles, etc.), and deliver prioritized fixes.
  • Evaluate each finding based on exploitability, economic impact, and compliance relevance.
  • Apply contextual CVSS scoring tailored for blockchain environments to prioritize remediation based on smart contract risk exposure.
  • Generate clear risk summaries to guide both technical and executive decision-making.

Outcome: Receive prioritized, actionable risk intelligence focused on blockchain and business impact.

Remediation Support

  • Deliver detailed, developer-focused remediation steps validated by our blockchain security engineers.
  • Provide reproducible PoCs, code-level fixes, and configuration guidance for faster issue resolution.
  • Collaborate directly with your developers to verify patch effectiveness and prevent reintroducing vulnerabilities.
  • Get documented remediation evidence aligned with compliance and audit requirements.

Outcome: Achieve faster, verified fixes supported by our experts and documented for full blockchain compliance.

What are blockchain security services?

Blockchain security services audit smart contracts, nodes, wallets, and DeFi protocols to find logic bugs, economic vulnerabilities, and infrastructure misconfigurations, helping teams prevent exploits and demonstrate security to stakeholders.

What are the benefits of blockchain security audits?

They reduce exploit risk, protect funds and user assets, improve investor and user trust, and provide documentation required for regulatory and commercial trust-building.

How much do blockchain audits cost?

Pricing depends on contract complexity, number of contracts, and infrastructure scope. Simple scans start at $69; full smart contract audits and enterprise blockchain assessments typically start at $5,999. Custom quotes are available for complex DeFi systems.

Can you provide a custom audit for my smart contracts or DeFi protocol?

Yes. We tailor audits to your codebase, protocol logic, and operational infrastructure, covering tokenomics, oracles, bridges, and governance mechanisms as needed.

Will your blockchain audits help with compliance and investor assurance?

Yes. We map findings to applicable standards and produce audit-ready reports and public attestations that help with investor due diligence and regulatory transparency.

How fast can I expect results?

Timelines vary by scope. Small contract reviews can be completed rapidly; larger protocol audits are scoped with clear milestones and turnarounds. Re-verification is provided after fixes.
