Hashlock

• Name: Hashlock
• URL: https://hashlock.com/
• Category: smart-contract security company / audit-report methodology operator / public audit-education and scanning-tool publisher
• Summary: Hashlock belongs in companies/, not projects/, because the durable control surface is a named security company that defines audit scope, publishes report structure, standardizes severity and remediation language, and now extends that methodology into a public AI scanning tool. The useful question is not what is the Hashlock protocol? but which organization controls the review workflow, report framing, educational material, and public security tooling that downstream teams may start treating as assurance infrastructure? That authority sits with the Hashlock company more clearly than with any standalone protocol surface.
• What it does:
  • Performs smart-contract and broader blockchain security audits and explicitly markets audit work as a trust and risk-mitigation layer for web3 teams
  • Sells review services across Solidity, Rust, and Move ecosystems rather than limiting itself to one chain family or one narrow audit niche
  • Publishes educational material explaining how audit reports are structured, how findings are classified, and how remediation status should be interpreted
  • Offers a free public AI audit tool that scans contracts, returns issue descriptions, proof-of-concept-style explanations, suggested fixes, and severity breakdowns while still framing manual audits as the production-grade control
  • Packages adjacent security surfaces such as monitoring and security scoring under the same company shell, which broadens the operator boundary beyond one-time code review
• Key claims:
  • The homepage says Hashlock delivers expert smart-contract audits and blockchain security trusted by top web3 protocols worldwide, which is a first-party framing signal that the company sees itself as an assurance operator rather than a narrow tool vendor
  • The official site says Hashlock combines automated and manual testing and explicitly highlights Rust, Solidity, and Move smart-contract audit services
  • The smart-contract-auditing page frames professional audits as the primary safeguard against irreversible smart-contract flaws and a core 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 company’s reporting grammar itself a reusable downstream artifact
  • The AI audit-tool announcement says the tool is 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 before production deployment
• Whitepaper: No classic standalone Hashlock whitepaper is the important artifact here. The stronger primary materials are 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.

Internal linkages

• Project-layer alias: hashlock.
• Strong adjacent company/operator comparisons: blockapex, oak-security, and halborn.
• Useful methodology-heavy adjacent reads: codespect and trail-of-bits.

Protocol / company boundary

• projects/hashlock should now be treated as an alias because Hashlock is not most usefully analyzed as a standalone protocol or neutral infrastructure primitive.
• The important surface is organizational: who scopes audits, who defines severity and remediation language, who publishes report-reading guidance, who decides how much methodology becomes public, and who packages those judgments into reusable scanning and education tooling.
• That makes the named company the cleaner note boundary. The practical authority is in Hashlock’s review and publication workflow, not in any supposed independent Hashlock protocol.

Control surface

• Practical leverage sits in review methodology, severity taxonomy, remediation-status framing, public educational authorship, scanning-tool defaults, and decisions about how Hashlock’s own audit corpus and guidance shape downstream security habits.

• Even if the scanner is free and the reports are educational, the company still controls which issue classes get emphasized, how findings are categorized, and what audit literacy gets normalized for clients and readers.

• Read Hashlock as a security-review and methodology operator, not as a neutral protocol primitive.
