Smart contract audits, line by line.
Senior manual review across EVM, Solana, Rust, Cairo, and Sway, paired with custom invariants, Slither, mutation testing, and Krait. Reports public by default.
Tools find patterns. People find bugs.
Static analyzers catch the issues that look like other issues. They miss the architectural mistakes, the broken invariants, and the protocol-specific bugs that actually cost money. We run the tools (all of them) and then we read the code, twice, with two senior auditors. The tooling is there to expand coverage, not to replace judgment.

Scoped to your codebase.
Audits are sized to your code, your stack, and your timeline. No fixed packages, no surprise add-ons. Talk to us for a scope and a quote.
Questions.
Solidity (every EVM chain), Solana (Anchor and native), Rust (Near and other non-Solana ecosystems), Cairo (Starknet, Madara), and Sway (Fuel). Pick the language page from the section above for the full scope on each.
Depends on scope and complexity. A typical audit runs 2 to 5 weeks of focused review by two senior auditors, plus a fix-verification pass. We give you a fixed scope and timeline before you commit.
By default, yes. Every audit gets published on zealynx.io with findings, severity, and recommendations. If your engagement requires confidentiality, we sign an NDA and keep the report private.
Yes. After you implement fixes, we re-review each finding to confirm the remediation is correct. Fix verification is included in the audit fee, not a separate engagement.
Yes — the Security Audit Subscription is a recurring engagement with weekly code review, a weekly call, and a direct line to your auditor. Built for protocols still being built, before they're ready for a full audit.
Manual review first, tools second. Read the full methodology page for our process, the tools we use at each phase, and how we structure the final report.
