We slay bugs,
not your budget.
From smart contracts to frontends, workers & APIs we approach every surface as an adversary would. Adversarial, methodical, relentless. No checklists. No bloated retainers.

AI Scan + Bug Filtering
We run your entire codebase through the Slayer Security AI Auditor, filter out the noise, and surface only the findings that matter — for free, before your paid engagement begins.
Smart Contract Audits
Our primary discipline. Adversarial, line-by-line review of Solidity and EVM-compatible contracts covering logic flaws, access control, economic exploits, reentrancy, oracle manipulation, and more.
Off-Chain Security Review
Blockchain exploits rarely stop at the contract. We audit the full stack — frontends, backend workers, indexers, and APIs — covering the attack surfaces most firms ignore.
Monitoring & Ongoing Security
Security does not end at deployment. We help you set up continuous monitoring, real-time alerts, and maintain a strong security posture as your protocol evolves.
5-stage samurai
review path.
Five sequential stages, every codebase, every engagement. We do not skip steps. We do not rush. We do not chase scope we close it.
Recon Sweep + AI Threat Mapping
Automated tooling combined with AI-assisted pattern recognition to map the attack surface before manual review begins. Scope is defined and locked here.
Blade-Level Manual Review
Line-by-line adversarial analysis. Every function, every state transition, every interaction surface scrutinized for logic flaws and exploitable conditions.
Battle Report + Severity Map
All findings documented with proof-of-concept exploits, CVSS-aligned severity ratings, and clear remediation paths. No vague recommendations.
Post-Fix Verification Pass
Every fix is reviewed. We confirm patches close the original vulnerability without introducing regressions or new attack vectors.
Security Doctrine for the Next Release
Monitoring setup, upgrade safety reviews, and long-term security posture guidance. Keeps your protocol defended as it evolves post-audit.
Our Samurai
Find every vulnerability before someone else does. Slayer is small by design, with every engagement led by senior security researchers. Now covering the full blockchain stack.
Leads protocol reviews across DeFi, L2s, and restaking. Known for high-signal findings and a deep command of Solidity internals and EVM mechanics.
Specializes in adversarial reasoning, economic exploit modeling, and uncovering complex logic vulnerabilities that survive automated tooling.
Specialist in off-chain attack surfaces. Brings deep expertise in frontend security, backend worker vulnerabilities, API attack paths, and signature exploits.
