The second you don't, you lose. Zellic identifies complex vulnerabilities that threaten the future of your blockchain project.
Don't ship with vulnerabilities. Give your developers the peace of mind they need to deliver securely.
Identify deadly mistakes like reentrancy, improper input validation, uninitialized data, and more.
Uncover critical vulnerabilities in core business logic. The code may match the spec, but is that what you really want?
Unmask economic flaws, including price manipulation (flash loan) hazards, MEV, front-running, and more.
“Zellic is an incredible and fast moving auditing team - on top of extremely timely, technical, and precise responses when asked, they also have found extremely unique and detailed obscure bugs down to the level of the Solidity quirks. The team’s diverse and deep security and hacking experience shows through in conversations, brainstorming, and technical discussions.”
"We've worked with a lot of auditors in the past, and Zellic is one of the best. They deep dive into our contracts, tear everything apart and give us the security we need to secure billions of dollars at Sushi. They're quick, responsive, and very precise while maintaining the highest quality and standards."
Zellic was founded by world-renowned hackers and researchers—leaders of traditional infosec. We were inspired by the glaring and embarrassing deficiencies in Web3 security. Our mission is to bring real security expertise to Web3, to uncover vulnerabilities that others miss.
We believe that Web3 adoption is impossible without true security, trust, and transparency. Our bet on the Web3 future is one with users’ security at the forefront. No one wants to invest in something that will collapse.
Before Zellic, Stephen & Jazzy founded a competitive hacking team named Perfect Blue. Perfect Blue was the #1 team worldwide in 2020 & 2021. They have competed internationally in competitions including DEF CON CTF and Google CTF.
Our team has exploited vulnerabilities in Chrome, iOS, and Android. We’ve reported vulnerabilities to Google, Apple, Microsoft, Facebook, Netflix, PayPal, CapitalOne, and many more.
It’s impossible to find bugs without fully understanding a project. We work with your team to actually learn how your project works. It’s personalized, and hands-on. We don’t just run automated tools—our engineers think deeply about exactly what could go wrong. This vulnerability research mindset is how we have the best track record in the industry.
