What we do

Comprehensive security services

From initial audit to ongoing protection, we provide end-to-end security solutions for blockchain projects.

Smart Contract Audits

Comprehensive line-by-line code review of your Solidity, Vyper, or Rust smart contracts to identify vulnerabilities and logic errors.

Penetration Testing

Simulated attack scenarios to test your protocol's resilience against real-world exploits and attack vectors.

Security Assessments

Full-stack security evaluation including architecture review, access control analysis, and economic attack modeling.

Gas Optimization

Identify inefficiencies and optimize your smart contracts for lower gas costs without compromising security.

Formal Verification

Mathematical proofs to verify that your smart contracts behave exactly as intended under all conditions.

Ongoing Security

Continuous monitoring, incident response support, and security advisory for protocol upgrades and changes.

Why HasFocus

Security built on rigour, not marketing

We let our process speak for itself. Here is what sets us apart.

Manual-First Methodology

Every line of code is reviewed by hand by senior researchers. Automated tools supplement but never replace human judgement.

PoC-Driven Findings

Critical and high findings come with working proof-of-concept code, leaving zero ambiguity about exploitability and impact.

Multi-Chain Expertise

Deep expertise across EVM chains (Ethereum, Arbitrum, Optimism, Base, Polygon), Solana, and CosmWasm ecosystems.

Complete Remediation Cycle

We review every fix your team applies and issue a follow-up report documenting the remediation status of each finding.

How it works

Our audit process

A rigorous, transparent methodology designed to uncover every potential vulnerability in your smart contracts.

Initial Review

We analyze your codebase, documentation, and project requirements to understand the scope and complexity of your protocol.

Deep Analysis

Our security researchers perform manual code review, automated testing, and formal verification to identify all potential vulnerabilities.

Detailed Report

You receive a comprehensive report with findings, severity ratings, and actionable remediation recommendations.

Verification & Certification

After fixes are implemented, we verify the remediation and provide a final audit certificate for your protocol.

Deliverables

What you receive

Every audit produces a comprehensive report designed for both your engineering team and your stakeholders.

HasFocus Audit Report

The standard deliverable for every engagement

Scope & Methodology

Every report begins with a clear definition of what was audited, the techniques used, and the time invested.

Findings with PoC

Each finding includes severity, root cause, affected code, a proof-of-concept, and a recommended fix.

Remediation Status

After your team applies fixes, we verify each one and document the remediation status in a follow-up report.
