About VLN
Elite security research lab protecting blockchain gaming and DeFi
Our Mission
VLN exists to make blockchain gaming and DeFi safer. We believe that security isn't an afterthought—it's a fundamental requirement for building trust in decentralized systems.
Through rigorous auditing, proactive threat modeling, and rapid incident response, we protect billions of dollars in user funds and ensure that vulnerabilities are found by defenders, not attackers.
Our Story
VLN (Vulnerability Lab Network) was born from 12 years of experience securing high-stakes systems at Fused Gaming. Our founders cut their teeth building secure infrastructure for iGaming platforms handling millions of dollars in daily transactions.
When blockchain gaming emerged, we recognized that the same security principles—threat modeling, attack surface analysis, and defense-in-depth—applied to smart contracts. But the stakes were even higher: immutable code, irreversible transactions, and billions of dollars at risk.
In 2021, we launched VLN as a dedicated security research lab focused exclusively on blockchain gaming and DeFi. We've since audited dozens of projects, discovered 47 critical vulnerabilities, assisted in recovering $5.2M in stolen funds, and maintained a 100% post-audit success rate—zero hacks for projects that implemented our recommendations.
Our team includes government-cleared security researchers, smart contract experts with hundreds of audits under their belts, and forensic analysts who've provided expert testimony in major legal cases.
We're not just auditors—we're security partners invested in your long-term success. That's why we offer free fix verification, rapid critical bug reporting, and ongoing support through retainer packages.
