McKinley's Technologies is a smart contract security and blockchain assurance firm. We help serious Web3 teams build, launch, and scale with confidence through rigorous audits across all major blockchain languages, pre-audit assessments, and remediation-focused guidance.
We review smart contracts and protocol logic with focus on what actually matters at launch. Exploitable vulnerabilities, privilege and access control risks, economic attack surfaces, upgrade and proxy risks, and cross contract integration weaknesses.
Our approach is practical, technical, and commercially aware. We work across Solidity, Rust, Vyper, Move, Cairo, and all major smart contract languages. We do not just identify issues; we help teams understand, prioritise, and remediate them before they become incidents.
View All ServicesWe audit smart contracts across all major blockchain languages. Your stack determines our scope, not the other way around.

Learn moreAssessment of front-end interaction risks, admin logic, wallet flows, signing assumptions, backend dependencies, and cross system trust boundaries.
Learn moreIndependent technical risk review for investors, allocators, and partners covering architecture risk, codebase maturity, admin governance, and exploit exposure.
Learn moreEvery engagement is researcher led and hands on. We focus on exploit paths, logic flaws, and systemic risk. Not surface level commentary generated by scanners. Judgment cannot be automated.
We work across Solidity, Rust, Vyper, Move, Cairo, and other blockchain languages. Coverage is assessed per scope. Your choice of language and chain does not limit what we can review.
Our output is built for remediation, not just reporting. Findings are structured, prioritised, and accompanied by actionable guidance that development teams can execute on immediately.
Clear, staged guidance that fits your development cycle. We support teams from early codebase review through full audit readiness without compromising depth at any stage.
McKinley's Technologies helps Web3 teams identify and resolve security risk before the market does.
Each engagement is designed around your stage, your stack, and your risk profile. No one size fits all packages.
Our smart contract audit is a structured technical assessment of your codebase, protocol logic, and architecture. We identify vulnerabilities, design weaknesses, trust assumptions, and exploit vectors across all major blockchain languages including Solidity, Rust, Vyper, Move, Cairo, and Yul.
Suitable for protocols at or approaching mainnet, teams undergoing investor diligence, and systems that require a formal reportable security attestation.
We audit contracts written in Solidity, Rust, Vyper, Move, Cairo, Yul, Scrypto, and other languages on a scope assessed basis. Confirm your stack when requesting an engagement.
A Soft Audit is a focused pre-audit security review designed for early-stage protocols and teams preparing for a more formal engagement. Ideal for MVPs, pre-testnet launches, and teams wanting to improve security posture before committing to a full audit round.
Full Soft Audit OverviewA Soft Audit is not a substitute for a full formal audit. It is a pre-audit check intended to improve security posture and codebase readiness.
Considers system design, role structures, governance, treasury controls, emergency powers, upgrade mechanisms, cross contract flows, and economic attack surfaces.
Many projects approach a formal audit too early. Our readiness review helps you prepare by assessing code maturity, documentation quality, test coverage, and deployment assumptions.
Front-end interaction risks, admin panel logic, wallet connection flows, signing assumptions, backend dependencies, off-chain services and relayers, and cross system trust boundaries.
Architecture and design risk, codebase maturity signals, admin and governance risk, exploit exposure overview, dependency concentration, and security posture summary for allocators and partners.
Tell us about your protocol and we will confirm the right audit type, timeline, and scope.
A consistent, researcher led process designed to identify risk thoroughly and support your team through remediation.
We begin by understanding the protocol, business logic, repository structure, deployment stage, and the precise contracts or components in scope. Clear scope prevents expansion and ensures depth where it matters.
We analyse the system design, asset flows, trust assumptions, role privileges, upgradeability, dependencies, and likely attack surfaces before touching the code, building an adversarial model of the protocol.
Detailed, line by line code review with attention to correctness, exploitability, logic flaws, and security anti-patterns. Researcher led. No automated scan substitution. Covers all languages in scope.
Targeted testing, static analysis, and technical validation to stress-test assumptions and confirm or challenge identified risk vectors. Findings are validated before classification.
A structured report setting out all identified vulnerabilities, impact assessment, severity classification, and recommended remediation actions designed for both technical and non-technical stakeholders.
After fixes are implemented by your team, we review the implemented changes and confirm whether identified issues have been fully, partially, or insufficiently resolved.
A final report is issued reflecting resolved issues, outstanding considerations, and the final reviewed scope. This constitutes the attestable deliverable from the engagement.
Most engagements range from one to four weeks, depending on scope size, code complexity, documentation quality, and team responsiveness during remediation.
Discuss Your TimelineFor many teams, the best first step is not a full formal audit. It is a sharp, technically informed pre-audit review that helps uncover major risk early.
Surface issues early enough to fix them before they compound. Before the market, investors, or attackers find them first.
Help founders prioritise fixes and eliminate high confidence exploit paths before committing to a full formal engagement.
Receive clear observations on code structure, quality, and maintainability, improving the codebase for a deeper audit.
Ensure your protocol is better positioned for a formal engagement, reducing scope uncertainty and maximising audit efficiency.
A Soft Audit is not a certification, guarantee, or replacement for a full formal security audit. It is a practical first-layer assessment designed to meaningfully improve your security posture before a formal engagement. We are direct about this distinction in all communications and deliverables.
Start with a Soft Audit. Get real security value at your current stage, with a clear path to full engagement when you are ready.
We provide security reviews across a range of Web3 and blockchain systems, from DeFi protocols and token infrastructure to dApps and novel architecture, in any major blockchain language.
We work with teams building custom protocol logic and novel architecture across any major blockchain language. Scope is assessed on a per-engagement basis during initial consultation.

Get in TouchMcKinley's Technologies treats all client information as strictly confidential by default. Our obligations extend from first contact through the full lifetime of any engagement deliverable.
All information received from clients, including but not limited to repository access, protocol documentation, business logic descriptions, codebase contents, findings, reports, and communications, is treated as confidential from the moment of first contact.
Confidentiality is the default position, not a negotiated term. No action is required from clients to invoke it.
Repository access granted for the purpose of an audit or review engagement is used solely for that engagement. We do not retain, copy, or store client codebases beyond the period reasonably required to complete the engagement and deliver findings.
Repository credentials and access tokens are not shared with any third party under any circumstances.
All audit reports, findings, and related deliverables are provided exclusively to the client. We do not publish, share, distribute, or reference any engagement deliverable in any form without the explicit prior written consent of the client.
Where a client requests publication of a report or findings summary, publication terms including scope, format, and attribution are agreed in writing before any disclosure is made.
We do not disclose the existence of an engagement, the identity of a client, or any details of the work performed to any third party, including media, other clients, or industry contacts, without explicit written authorisation from the client.
This obligation survives the conclusion of any engagement and applies indefinitely unless expressly modified in writing by the client.
Access to client materials within McKinley's Technologies is restricted on a need-to-know basis. Only team members directly assigned to an engagement are granted access to that engagement's materials.
Internal communications regarding client engagements are conducted through secure, access-controlled channels.
Where McKinley's Technologies shares proprietary methodology, tooling information, or internal process documentation with a client in the course of an engagement, we expect equivalent confidentiality obligations to apply in return.
Mutual confidentiality terms can be formalised through a Non-Disclosure Agreement at the client's request prior to commencing any engagement.
In the event that a critical or high-severity vulnerability is identified that poses an immediate and material risk to third parties beyond the client's protocol, such as in the case of a shared dependency or integrated protocol, McKinley's Technologies reserves the right to discuss appropriate responsible disclosure procedures with the client.
Any such discussion will be conducted privately with the client first, and no disclosure to third parties will be made without client agreement except where required by applicable law.
