Security Audit Services
Solidity Audits
Line-by-line manual review of EVM smart contracts with automated analysis
Rust & Solana Audits
Account validation, CPI safety, and program logic review for Rust-based chains
DeFi Security
Economic attack modeling, oracle analysis, and governance review for DeFi protocols
Formal Verification
Mathematical proof that critical contract properties hold under all inputs
Bridge Audits
Multi-chain validation, message verification, and asset custody review
Pen Testing
Adversarial attack simulations against your full Web3 infrastructure
Incident Response
Emergency exploit analysis, fund tracing, and security hardening
Augmented by Sentinel
Our auditors are backed by Sentinel, an internal AI engine we built to extend coverage beyond what manual review alone can reach. It handles automated scanning and analysis at scale, so our team can focus on the vulnerabilities that require human judgement.
Turnaround
12–24h
Initial findings on most codebases. Sentinel runs scale coverage while our auditors focus on the bugs that need human judgement.
Recon
Codebase ingestion and scope analysis
Automated Sweep
Static analysis and fuzzing
Agentic Analysis
AI-driven threat review
Cross-Examination
Findings challenged and stress-tested
Human Validation
Auditor sign-off on every finding
Report
Severity ratings and remediation
Monitored by Tripwire
Audits are point-in-time. Threats are continuous. Tripwire monitors your deployed contracts 24/7, detecting governance attacks, oracle manipulation, abnormal fund flows, and contract upgrades, alerting you in real time.
Reaction
< 30s
From on-chain signal to automated runbook execution. Pre-approved actions trigger before exploit windows close.
Real-Time Detection
On-chain pattern monitoring catches threats as they emerge
Multi-Channel Alerts
Slack, Telegram, and email. Your team knows in seconds
Automated Response
Pre-approved runbooks that execute within seconds of detection
Custom Deployment
Tuned to your contracts, parameters, and risk thresholds
Audit-Informed Rules
Monitoring seeded from SigIntZero audit findings

The $3.2M SquidRouterModule Exploit: How a Public String Drained 86 Safe Wallets
A third-party module named SquidRouterModule drained $3.2M from 86 Gnosis Safe wallets on Ethereum and Base. Full attack chain, the auth flaw, and the lesson.
GitHub's 3,800-Repo Breach: How a Poisoned VS Code Extension Burned the World's Biggest Code Host
One poisoned VS Code extension on one GitHub employee's laptop cost the company ~3,800 internal repositories. Here is the attack chain, the Mini Shai-Hulud worm internals, and the rotate-everything checklist that follows.
Reserve Manipulation Isn't Dead
Seven BSC pools drained $3M in 2026 H1 — same reserve-manipulation primitive every time. Here's what auditors keep missing.
