Not an audit firm.
A persistent red team.
Traditional audits produce a report and walk away. We build a continuously evolving threat model of your protocol, prove vulnerabilities with working exploits, and keep hunting after the first engagement. Your security posture improves every week, not once a year.
Protocol Topology Mapping
We build a complete map of your protocol's architecture — every contract, every interaction, every dependency. This goes far beyond source code review. We identify the relationships between components that create exploitable surfaces invisible to traditional audits.
Continuous Adversarial Testing
Our systems run continuously against your protocol. When you deploy new code or the market environment changes, analysis begins automatically. We don't audit once and walk away — we keep looking until there's nothing left to find.
Fork-Validated Proofs of Concept
Every finding is backed by a working exploit on a mainnet fork. Real contracts, real state, real token balances. If our PoC extracts value, the vulnerability is real. If we can't prove it, you don't pay.
Proprietary Detection Systems
Purpose-built technology that identifies vulnerability patterns no other platform can find. We discover systemic risks that span multiple contracts and protocols — the kind of deeply embedded issues that checklist audits miss entirely.
Multi-Strategy Analysis
We analyze your protocol from 20+ distinct adversarial perspectives simultaneously. The combined coverage finds vulnerabilities that no single approach — manual or automated — would uncover on its own.
Patch Verification
When you fix a finding, we re-run the exploit against your patched code. If the fix is incomplete or introduces new issues, we catch it before production. This closed-loop verification ensures vulnerabilities stay fixed.
The only security service that delivers fixes, not just findings.
Every validated finding comes with a tested, deployable Solidity patch. We don't hand you a PDF and wish you luck—we stage a draft PR on your repo, ready to merge with one click. Your team reviews the fix, accepts the finding, and the patch is live. From detection to deployment, the entire remediation lifecycle is handled.
Detection
Vulnerability identified and validated with a working proof-of-concept on mainnet fork.
Fix Generation
Solidity patch and corresponding tests auto-generated, verified against the original PoC.
Staged PR
Draft PR created on your repo, invisible until you accept the finding. No noise, no spam.
One-Click Deploy
Accept the finding, PR activates, fix is ready to merge. Remediation in minutes, not weeks.
Text-based remediation recommendations with every finding. Guidance your team can implement directly.
Staged PRs for all Critical and High severity findings. Tested patches ready to merge on your repo.
All severities receive staged PRs. 24-hour SLA on patch delivery. Incident response included.
No other security firm does this. Traditional auditors deliver a report. We deliver a report, a working exploit, and a tested fix staged on your repo. The gap between “finding” and “fixed” drops from weeks to minutes.
Individual vulnerabilities are the starting point, not the end.
Traditional audits report findings in isolation. In reality, attackers chain multiple vulnerabilities together into compound exploits that bypass defenses no single finding would predict. BlackHart's proprietary engine maps how vulnerabilities compound into multi-step attack chains—what we call zero-day chains.
Multi-Step Attack Paths
We map how a low-severity issue in one contract combines with a medium-severity issue in another to create a critical-severity exploit path. These compound chains represent real-world attack scenarios.
Vulnerability Composition
A revoked signer + permission survival + compound interaction = persistent theft channel. Each finding alone might be Medium. Chained together, it is a Critical with immediate fund loss.
Invisible to Single-Finding Audits
Traditional audits report each vulnerability independently. They miss the compound interactions that real attackers exploit. Zero-day chains catch what isolated findings never will.
No other security firm does this. Zero-day chain detection is BlackHart's core differentiator. While others deliver lists of individual findings, we deliver the attack paths that real adversaries would use to drain your protocol.
Reconnaissance
We ingest your entire protocol and build an internal model of its architecture. Every contract, every external dependency, every trust assumption is catalogued. This baseline informs everything that follows.
Surface Enumeration
Our systems automatically enumerate tens of thousands of potential attack surfaces across your protocol. This is not a line-by-line code review — it's a systematic search across every interaction path between components.
Adversarial Analysis
20+ distinct adversarial strategies run simultaneously, each probing for a different class of vulnerability. The breadth and depth of this analysis is what separates our approach from traditional security reviews.
Attack Vector Analysis
Individual findings are analyzed for how they interact. A low-severity issue in one contract combined with a medium-severity issue in another can escalate to critical impact. Our systems identify these relationships automatically.
Proof of Concept
Every viable chain is tested on a mainnet fork with real contract state and real market conditions. If the exploit works, it's confirmed with a passing test. If it doesn't, we iterate until we either prove it or rule it out.
Continuous Monitoring
After initial delivery, our systems keep running. Code changes, market shifts, and dependency updates trigger re-analysis. New findings appear in your feed as they're discovered — not in a report months later.
Every client gets access to a dedicated threat intelligence dashboard — a common operating picture for your protocol's security posture.
Live Threat Map
VISUALInteractive contract topology with severity overlays. Click any contract to see its functions, attached findings, and vulnerability exposure. Updated in real-time as our systems discover new surfaces.
Intelligence Feed
REAL-TIMEReal-time stream of findings, research signals, pipeline scans, and validated PoCs. Filter by severity, type, or contract. Know the moment we find something — not weeks later in a PDF.
Finding Unlock System
GATEDEach validated finding includes a full vulnerability report, working PoC, step-by-step exploit walkthrough, and remediation guidance with code patches. Unlock individually or get everything with Vanguard/Citadel tiers.
Email Notifications
ALERTSGet notified the moment a new finding is validated. Each notification includes severity, impact category, TVL at risk, and a link to your threat intelligence report. Never miss a critical discovery.
Our detection engine supports the full spectrum of DeFi protocol architectures. If it runs on-chain, we can audit it.
Zero-Day Hunt
30-day dedicated engagement with a money-back guarantee. We hunt for zero-days in your protocol with 14 parallel adversarial models. Every finding gets a fork-validated PoC. If we don't find a Critical or High severity vulnerability, you get your deposit back.
