Hey folks 👋
We recently crossed an important milestone - 8 years of QuillAudits.
Back in 2018, smart contract security was barely a defined space. DeFi was still experimental, most of today’s security firms didn’t exist, and reentrancy was the biggest concern developers had.
Fast forward to today, and the landscape has completely transformed. Attacks have grown far more sophisticated, evolving into cross-protocol and economic exploits. In 2025 alone, the ecosystem saw nearly $4 billion lost to hacks.
Through it all, we’ve stayed consistent, building across 3 bear markets, multiple exploit cycles, and every phase of Web3’s evolution.
1,500+ protocols audited. $3B+ in user funds protected. 1M+ lines of code reviewed. Working alongside teams like StarkWare, Taiko, ZetaChain, and Metis.
And if there’s one thing we’ve learned from all of it, it’s this: security cannot rely on a single layer anymore.
One team. One approach. One audit pass, it doesn’t hold up when millions (or billions) are at stake.
That realization led us to build what we call the Multi-Layer Audit, a system where multiple independent security layers operate in parallel, without slowing down delivery.
Senior auditors.
AI agents trained on 5,000+ real exploits.
Curated bug bounty researchers.
Continuous post-deployment monitoring.
All working together as a unified defense system.
Looking ahead, we believe Web3’s path to a $100T opportunity depends on making security invisible, reliable, and non-negotiable, much like HTTPS today.
That’s the thinking behind QuillShield, our AI-powered Red Team Copilot, designed to bring 8 years of audit intelligence directly into developer workflows, even before code reaches mainnet.
8 years in and it still feels like day one.
Thanks for being part of the journey.
Here’s to building the future, one block at a time.
Catch you soon? 😉
See you out there,
Team QuillAudits
