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
Triage
Findings deduplicated, ranked, and filtered for noise
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

Injective npm SDK Backdoored to Steal Wallet Keys: Anatomy of a Near Miss
A compromised maintainer account backdoored 18 @injectivelabs npm packages on July 8, 2026, harvesting wallet seed phrases at key-derivation time. It failed by minutes. Here is how it nearly worked.
Summer.fi's $6M Lazy Summer Exploit: When a Donation Broke the Vault Math
An attacker donated an asset into a Summer.fi Lazy Summer vault, inflated its totalAssets() share price, and redeemed a flash loan for a $6M profit. No key was stolen. The accounting was the hole.
BonkDAO's $20M Governance Takeover: When Buying the Vote Beats Hacking the Code
An attacker spent about $4M buying BONK, took a voting majority on BonkDAO's Realms governance, and passed one proposal that moved $20M out of the treasury. No contract was hacked. The rules were.
