Smart Contract Security Audits

Service Overview

Zealynx provides comprehensive smart contract security audits combining expert manual review with advanced fuzzing and formal verification techniques. Supporting multiple languages including Solidity, Rust, Cairo, and Sway, Zealynx audits cover DeFi protocols, staking systems, NFT platforms, and payment infrastructure across Ethereum, Solana, Starknet, and emerging blockchain ecosystems.

Core Service Components

Multi-Language Audit Coverage

Solidity Audits: Deep expertise in Ethereum and EVM-compatible smart contracts, covering the full spectrum of DeFi primitives and complex protocol interactions.

Rust & Solana Audits: Specialized security reviews for Solana programs, leveraging understanding of the Solana runtime and common vulnerability patterns.

Cairo Audits: Security assessments for Starknet contracts with knowledge of Cairo-specific considerations and ZK integration points.

Sway Audits: Coverage for Fuel Network contracts, positioning clients on emerging high-performance blockchains.

Advanced Security Techniques

Fuzzing: Automated testing with randomized inputs to discover edge cases and unexpected behaviors that manual review might miss.

Formal Verification: Mathematical proofs of contract correctness for critical functions requiring the highest assurance level.

Comprehensive Testing: Integration of unit tests, invariant testing, and scenario-based testing throughout the audit process.

Real-Time Collaboration Portal

Live Status Tracking: Proprietary portal (portal.zealynx.io) providing real-time visibility into audit progress, findings, and remediation status.

Direct Communication: Streamlined communication channels for questions, clarifications, and collaborative problem-solving during the audit.

Why Web3 Projects Need This Service

Smart contract vulnerabilities continue to cause billions in losses across DeFi and Web3. Projects building on emerging blockchains face additional risks from less-mature tooling and fewer battle-tested patterns. Zealynx's multi-chain expertise and focus on newer ecosystems like Fuel and Starknet provides security coverage where other auditors may lack depth.

The combination of traditional manual review with advanced techniques like fuzzing catches both logical vulnerabilities and edge-case behaviors that pure manual review misses.

Target Clients

• DeFi protocols on Ethereum, Solana, or Starknet
• Projects building on emerging blockchains (Fuel, NEAR)
• Staking and liquid staking protocols
• NFT platforms and marketplaces
• Payment infrastructure and bridging solutions
• Projects requiring fuzzing and formal verification expertise

Firm Differentiators

Multi-Ecosystem Expertise: True depth across Solidity, Rust, Cairo, and Sway, not just surface-level coverage.

Emerging Blockchain Focus: Specialized knowledge in Fuel Network, NEAR, and other next-generation platforms where auditor options are limited.

Founder Pedigree: Founded by Carlos (Bloqarl) with experience at Pashov Audit Group and Cyfrin, bringing established methodology and industry connections.

Strategic Partnerships: Relationships with Cyfrin, Pashov Audit Group, and Shieldify enable access to additional expertise for complex engagements.

Transparency Through Technology: Real-time portal access ensures clients always know audit status and can collaborate efficiently.
