BACKGROUND

Please describe your company and position.

I am the COO of 4irelabs

Describe what your company does in a single sentence.

4irelabs is a software engineering company that builds fintech and blockchain products, including digital banking platforms, DeFi protocols, and RWA tokenization systems.

OPPORTUNITY / CHALLENGE

What specific goals or objectives did you hire Hashlock to accomplish?

• Bring an independent security review into our delivery process for the DeFi and tokenization products we build.
• Get audit reports rigorous and clear enough to stand in front of our clients and their stakeholders in finance.
• Have every fix verified by the same auditors before release, so nothing ships with open findings.

2-5 Employees

Describe the scope of work in detail. Please include a summary of key deliverables.

We build blockchain products for clients in fintech and finance, and an independent security review is a fixed step in how we deliver. On this engagement, Hashlock audited the smart contracts behind a product our team developed. Their auditors went through the codebase covering access control, business logic, and overall code quality, then mapped each finding to a severity level with a recommended fix. Our engineers worked through the remediations, and Hashlock verified every one of them before signing off. The final audit report became part of the launch package we handed over to the client.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

Every finding raised in the audit was fixed and verified before launch, and the product went live on schedule. The report gave our client the independent assurance they needed, which counts for a lot when the end users sit in finance and regulated markets.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Smooth from start to finish. We agreed on dates at kickoff and they met all of them, and whenever our engineers had a question about a finding, the answer came back quickly and in plain engineering terms. Communication ran over calls and a shared channel, which kept everything moving.

What was your primary form of communication with Hashlock?

Virtual Meeting

What did you find most impressive or unique about this company?

The depth and the clarity of their work stood out. The audit went well past surface level checks into the business logic of the contracts, and the report was structured so well that we could hand it to our client and their stakeholders without reworking a thing. We ship for companies in finance and regulated markets, and a security partner whose work holds up at that level is a real asset.

Are there any areas for improvement or something Hashlock could have done differently?

Honestly, nothing worth flagging. If we had to name one thing, next time we would simply bring them in even earlier in the build.

2-5 Employees

Describe the scope of work in detail. Please include a summary of key deliverables.

Hashlock acted as our security partner on the Web3 products we build for clients. We develop smart contracts, DeFi components, and dApps, and we brought Hashlock in to audit that code before it reached production. The scope included a full review of the contract codebase for security vulnerabilities, logic issues, code quality, and adherence to best practices.

Hashlock delivered a detailed audit report with clear findings, severity levels, and remediation guidance written in a way our engineers could act on directly. After we addressed the issues, Hashlock reviewed the fixes and confirmed they were resolved, which let us hand off a secure, audited product with confidence.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

Hashlock identified vulnerabilities and code quality issues in the contracts we audited, which our team fixed before deployment. The fixes were checked too and a final report issued. The audited products launched on schedule with an independent security review behind them, and our clients gained real confidence from knowing the code had been checked by a dedicated and well-known Web3 security team.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Hashlock was genuinely easy to work with. They were fast, responsive, and right on spot. They delivered the audit reports on time, kept us in the loop throughout, and fit cleanly into our sprint timelines, which matters a lot when we are shipping on our desired schedule.

What was your primary form of communication with Hashlock?

• Virtual Meeting
• Email or Messaging App

What did you find most impressive or unique about this company?

What stood out most was how well Hashlock worked alongside our engineering team. They explained security findings in practical, code-level terms in their report so our developers could act on them immediately, and they moved fast, checking our fixes. It felt less like outsourcing an audit and more like adding a security team to our own.

Are there any areas for improvement or something Hashlock could have done differently?

Nothing significant comes to mind. The collaboration was smooth, the work was solid, and the process fit the way we build. Any refinements would be minor and did not affect the quality or the outcome.
