Comprehensive security solutions for the blockchain ecosystem

Smart Contract Audits

Line-by-line manual review combined with automated analysis. We examine your Solidity, Vyper, or Move contracts for vulnerabilities, logic errors, and gas inefficiencies.

  • Reentrancy & flash loan attacks
  • Access control vulnerabilities
  • Integer overflow/underflow
  • Oracle manipulation risks

Penetration Testing

Full-stack security assessment including frontend, backend APIs, and infrastructure. We simulate real-world attacks to uncover weaknesses across your entire system.

  • Web application security
  • API endpoint analysis
  • Private key management
  • Infrastructure hardening

Incident Response

24/7 emergency support when things go wrong. We help identify attack vectors, contain damage, and guide recovery. Time is critical during an exploit.

  • Attack vector analysis
  • Fund recovery assistance
  • Post-mortem reports
  • Remediation guidance

// Our Process

A systematic approach to securing your smart contracts

01

Scoping

We analyze your codebase, understand your protocol's architecture, and define the audit scope together.

02

Analysis

Deep dive into your code using manual review, static analysis, and custom fuzzing to uncover vulnerabilities.

03

Reporting

Detailed findings report with severity ratings, proof-of-concept exploits, and remediation recommendations.

04

Verification

We verify all fixes, provide a final report, and issue a certificate of audit for your protocol.
