Tactical Capabilities
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.
$10.77B+
Lost to exploits, often by protocols that passed traditional audits.
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.
< 20 min.
Average time from exploit start to fund drain. Human reaction alone isn't fast enough.
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

Copy Fail: When a Linux Bug Becomes Protocol Risk
Copy Fail is a Linux kernel privilege escalation, not a smart contract bug. For Web3 teams running validators, CI runners, deployer hosts, and signing infrastructure, that's exactly why it matters.
Kelp DAO's $292M Hack and Aave's $6B Fallout: One Config Parameter Broke DeFi
A 1-of-1 LayerZero DVN let attackers drain 116,500 rsETH ($292M) from Kelp DAO, loop it through Aave V3 for $266M in ETH, and wipe $6B in Aave TVL in 24 hours. No Solidity bug. One config parameter broke DeFi.
The Delve Scandal: How a $300M Compliance Startup Sold Fake SOC 2 Reports and Got Expelled from YC
YC expelled Delve after an investigation revealed 493 of 494 SOC 2 reports were identical boilerplate. Here's the full breakdown of the $300M compliance fraud.
