Blockchain & Smart Contract Auditing
Security audits for smart contracts, DeFi protocols, and Web3 applications
What this engagement covers
The service
Our blockchain security audits identify vulnerabilities in smart contracts, DeFi protocols, and Web3 applications before they go live. We review Solidity, Rust, and Move contracts for logic flaws, reentrancy attacks, access control issues, and economic exploits that could lead to fund loss.
What we test
We audit smart contracts on Ethereum, Solana, and other major chains for common and advanced vulnerability classes including reentrancy, integer overflow, front-running, oracle manipulation, flash loan attacks, access control bypass, and economic design flaws. We also assess the Web3 frontend, wallet integrations, bridge security, and governance mechanisms.
Scoping & Assessment Depth
Black Box Assessment
Zero-KnowledgeSimulates an external adversary targeting Blockchain & Smart Contract Auditing with no internal credentials, source code, or architecture documentation. Assesses perimeter exposure, unauthenticated attack paths, and edge resilience.
Gray Box Assessment (Recommended)
CredentialedSimulates an authenticated user, tenant, or insider threat within Blockchain & Smart Contract Auditing. We evaluate role segregation, authorization boundaries, privilege escalation, and business logic flaws across user tiers.
White Box / Source-Assisted
Full-KnowledgeConducted with direct access to architecture schematics, configuration files, and API/code documentation. Eliminates blind spots and provides exhaustive coverage of security mechanisms governing Blockchain & Smart Contract Auditing.

How we run it
We combine line-by-line manual code review with automated static analysis using tools like Slither, Mythril, and custom analysis. Every function is traced through all possible execution paths. We model economic attack scenarios and test for edge cases that automated tools miss. Our team understands both the cryptographic fundamentals and the DeFi composability risks unique to blockchain.

What you receive
Findings land in your tracker as you go, not only in a PDF at the end. Retest is in scope, not a change order.
- Line-by-line smart contract audit report
- Vulnerability classification by severity
- Proof-of-concept exploits for critical findings
- Gas optimization recommendations
- Economic and governance risk analysis
- Static analysis tool output and coverage report
- Remediation guidance with code fix suggestions
- Post-fix verification and final attestation
What we usually find
The issues this engagement surfaces most often. Yours will differ, but this is the shape of it.
Who this is for
Auditor-Ready Compliance Crosswalk
| Framework | Control Section | Testing Evidence & Report Deliverable |
|---|---|---|
| SOC 2 Type II | CC4.1, CC7.1, CC7.2 | Technical testing evidence validating system boundaries, access restrictions, and vulnerability identification controls. |
| ISO/IEC 27001:2022 | Control A.8.8 & A.8.20 | Management of technical vulnerabilities and network security verification through independent technical assessments. |
Findings are mapped to OWASP Smart Contract Top 10, CER Certification, SOC 2, ISO 27001, so the report drops into an audit package rather than needing to be translated first. If you need the readiness work behind one of those, that is a separate engagement.
Frequently Asked Questions
Direct answers on scoping, methodology, compliance validation, and deliverables.
Our Blockchain & Smart Contract Auditing service combines deep manual testing with automated verification. We cover: Line-by-line smart contract audit report, Vulnerability classification by severity, Proof-of-concept exploits for critical findings, Gas optimization recommendations, Economic and governance risk analysis. Every engagement includes reproducible proof-of-concept exploits, developer-ready remediation guidance, and a free retest.
Yes. Findings are directly mapped to OWASP Smart Contract Top 10, CER Certification, SOC 2, ISO 27001 control requirements. The resulting report is auditor-ready and formatted for immediate submission to SOC 2 CPAs, PCI QSAs, and enterprise vendor risk assessment teams.
Yes. Every Lorikeet Security engagement includes free retesting within 30 to 60 days to validate that your remediation patches successfully resolve the identified vulnerabilities before your final report is issued.
Typical active testing turnaround is 1-3 weeks, with critical findings reported immediately via your Talon portal so your engineering team can begin remediation without waiting for the final PDF.
Pricing starts from $12,000. We scope the engagement in one call based on your environment's surface area, user roles, and complexity, providing a transparent, fixed-price quote with no hidden change orders.
