Summary: Hashlock is better cataloged as web3 security infrastructure than as a narrow audit boutique. In this pass, the clearest first-party evidence came from the official site, the smart-contract-auditing service page, Hashlock’s public explainer on how to read audit reports, and the company’s free AI audit-tool announcement. Taken together, those materials show a firm that is not only selling manual audits, but also publishing reusable security education, standardizing how it frames report sections and severity/status labels, and extending that methodology into a public self-serve scanning tool for builders.
What it does:
Performs smart-contract and broader blockchain security audits for web3 teams and positions audits as a core trust and risk-mitigation layer
Markets language- and stack-specific review services across Solidity, Rust, and Move smart-contract ecosystems, alongside broader web3 and blockchain audit work
Publishes educational material explaining how audit reports are structured, how findings are classified, and how stakeholders should interpret remediation status
Offers a free public AI audit tool that scans smart contracts, returns vulnerability descriptions, proof-of-concept style explanations, suggested fixes, and severity breakdowns, while explicitly positioning it as a complement to manual audits rather than a replacement
Extends the security surface beyond one-time code review into adjacent products such as on-chain monitoring and security scoring, based on the official site’s service navigation and positioning
Key claims:
The homepage meta description says Hashlock delivers expert smart-contract audits and blockchain security trusted by top web3 protocols worldwide
The official site says Hashlock’s audits use a combination of automated and manual testing and explicitly highlights Rust, Solidity, and Move smart-contract audit services
The smart-contract-auditing page frames auditing as the primary safeguard against irreversible smart-contract flaws and says a professional audit is the main credibility signal for projects, investors, partners, and users
Hashlock’s audit-report explainer lays out a standardized report structure spanning executive summary, project context, audit scope, security rating, intended functionality, code quality, dependencies, severity definitions, status definitions, findings, centralization, conclusion, methodology, and disclaimers
The same explainer says Hashlock uses five finding classes — High, Medium, Low, Gas, and QA — plus response labels such as Resolved, Acknowledged, and Unresolved, which makes the firm’s reporting approach itself a reusable educational artifact
The AI audit-tool announcement says the tool is completely free, built specifically for web3 security, backed by Hashlock’s auditing methodology and dataset, and intended for developers, auditors, and DeFi teams
The AI-tool page also says the scanner provides custom vulnerability descriptions, proof-of-concept guidance, suggested fixes, and severity-based categorization, while still recommending manual professional audits for production deployments
Whitepaper: No canonical standalone Hashlock whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, the smart-contract-auditing page, the audit-report explainer, and the AI audit-tool announcement; see ../whitepapers/hashlock-primary-sources-2026-05-04.md.
