Smart Contract Security Audits

Zealynx delivers comprehensive manual smart contract security audits for EVM-compatible chains (Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Base, Monad, Berachain, and all major EVM networks) and Solana. The audit process combines line-by-line manual code review with static analysis tools (Slither, Aderyn) and fuzz testing (Foundry) to detect vulnerabilities, logic flaws, and potential exploits before deployment.

Languages Covered

Solidity (EVM), Rust (Solana/cross-chain), Cairo (Starknet), Sway (Fuel Network), and Anchor/TypeScript (Solana).

Engagement Tiers

Private Audit (1–4 week engagement): Manual security review, fuzzing, detailed report with severity ratings and mitigation guidance, 2-week post-engagement support, and a free re-audit included.

Zealynx Internal Security (monthly subscription): Ongoing security support at development stage, smart contract audit for existing code, security reviews for new changes, fuzzing support, fully dedicated security team, and knowledge transfer.

Full Protocol Security (3–6 week engagement): Combines penetration testing and smart contract audit with full fuzz test coverage, detailed reports, and 4-week post-engagement support.

Audit Portal

All engagements are supported by the Zealynx Audit Portal — a proprietary secure command center providing real-time transparency throughout the audit. Key features include a live vulnerability feed (view findings as they are discovered), continuous CI/CD integration for automated security checks in the development pipeline, direct engineer access (no account managers), and living security documentation that persists after the engagement ends.

Track Record

Completed 40+ audits for protocols including Lido Finance, BadgerDAO, Wedefin, Monadex, and Lido Finance. 260+ total vulnerabilities found with a 49% rate of high/medium severity issues per audit. Zero critical bugs post-launch record.
