# FYEO — Blockchain & Web3 Security Audits

> FYEO is a cybersecurity company specializing in hybrid AI + human-led security audits for blockchain protocols, smart contracts, and Web3 applications.

## About FYEO

FYEO delivers security auditing services that combine AI-guided code analysis with expert human validation. Unlike purely automated tools, FYEO's hybrid approach reduces false positives by up to 85% while catching business logic vulnerabilities that scanners miss.

Founded by security veterans with deep expertise in blockchain protocols, FYEO serves leading projects across Ethereum, Solana, Cosmos, Polkadot, Cardano, Aptos, Sui, NEAR, Algorand, Axelar, and Flare ecosystems.

## Core Services

### Blockchain Security Audits
- Smart contract security reviews for Solidity, Rust, Move, and other blockchain languages
- Hybrid AI + human methodology: AI surfaces anomalies, experts validate exploitability
- Severity-ranked findings with reproduction steps and remediation guidance
- Post-fix verification reviews included

### Agentic AI Security Audits
- Security analysis of AI agent integrations in Web3 protocols
- Evaluation of AI decision-making boundaries and failure modes
- Assessment of prompt injection, data poisoning, and model manipulation risks
- Review of AI-driven governance and trading systems

### Blockchain Fuzz Testing
- Automated property-based testing for smart contracts
- Coverage-guided fuzzing to discover edge cases and invariant violations
- Integration with existing CI/CD pipelines
- Support for Solidity, Rust, and Move contracts

### Third-Party Library Scanner
- AI-powered dependency vulnerability detection
- Context-aware analysis of how libraries are actually used in your codebase
- Supply chain risk assessment
- GitHub App integration for automated scanning via the "fyeo-audit" label

## Key Differentiators

1. **Hybrid AI + Human Approach**: AI guides expert attention to high-risk code areas; humans confirm real-world exploitability
2. **Protocol Context**: Auditors understand DeFi mechanics, tokenomics, and governance edge cases
3. **Reduced False Positives**: 85% fewer false positives compared to pure automated tools
4. **Full Ecosystem Coverage**: Support for 13+ blockchain ecosystems
5. **Retainer Model**: Discounted rates, shorter wait times, and access to full tool suite

## FAQ

Q: What is a hybrid AI-human security audit?
A: A hybrid AI-human audit combines AI-guided code diff analysis and third-party library scanning with expert human validation. AI surfaces the anomalies and risk patterns — security engineers verify exploitability, apply protocol context, and deliver actionable remediation.

Q: How is this different from automated AI audit tools?
A: Automated tools scan code and generate reports, but they lack business logic understanding, protocol-specific context, and the ability to reason about complex DeFi interactions. FYEO's hybrid approach uses AI to guide human attention to the exact locations that matter, then experts confirm real-world impact.

Q: Do you replace human auditors with AI?
A: No. AI augments auditors — it doesn't replace them. AI identifies risky code diffs and vulnerable dependency patterns. Security engineers then validate, exploit, and contextualize every finding.

Q: How do you analyze third-party libraries?
A: FYEO's AI-powered library scanner identifies vulnerable dependencies, outdated packages, and exploitable supply-chain patterns. Unlike generic CVE scanners, the system understands how dependencies are actually used in your codebase, filtering out irrelevant alerts.

Q: Can AI detect business logic vulnerabilities?
A: AI can flag suspicious patterns — such as unusual state transitions, governance edge cases, or tokenomics anomalies. Confirming these requires human expertise, which is why the hybrid model is essential.
