DeFi loses billions to exploits every year. We exist to change that.
The traditional audit model is broken.
BlackHart Security was founded on a simple observation — protocols pay $200K+ for a point-in-time review, receive a PDF, and hope nothing changes. But protocols evolve daily. New deployments, dependency updates, and market conditions create attack surfaces that periodic audits miss entirely.
We take a different approach. We build a persistent, evolving threat model of your protocol and prove vulnerabilities with working exploits. Our technology runs continuously, not once.
When we find something, you know it's real — because we prove it on a mainnet fork before we report it.
Protocols Analyzed
Vulnerabilities Identified
Critical Findings
TVL at Risk
Fork-Validated PoC Tests
Criticals Backed by Exploits
verifiedEvery finding is fork-validated with a passing proof of concept. We don't report theoretical risks — we prove real ones.
We Prove, Not Report
Every finding includes a working exploit on a mainnet fork. If our PoC doesn’t work, we don’t report the finding. If it does, you know exactly what’s at risk.
Continuous, Not Periodic
Our systems run against your protocol 24/7. When conditions change — new code, new market dynamics, new dependencies — we re-analyze automatically.
Compound Vulnerabilities
We specialize in finding multi-step exploits where individually safe components create critical risk when combined. These are the exploits that drain protocols — and the ones that single-contract audits miss.
You Only Pay For What We Prove
Our pricing is performance-based. Base engagement fee plus bonuses only for validated, fork-proven findings. Our incentives are aligned with yours.
Security researchers. Exploit developers. Protocol architects.
BlackHart is led by security researchers with deep expertise in DeFi protocol architecture, on-chain exploitation, and formal verification. Our team combines hands-on exploit development with proprietary detection technology to deliver results that traditional audit firms cannot match.
