What our clients say

"Working with BailSec was the first time we saw that level of depth and rigor (they literally wrote full integration tests with chain fork because they felt static audit wouldn't cover it). This is what we want when we pay for an audit."
"… We went with @bailsecurity - not one of the usual big names, but a team we heard about from other top-tier auditors we respect. Best decision we could've made. First off, they were fair in their pricing. No inflated quotes, no pay-for-a-pass nonsense—just straight-up professionalism. But what really stood out? Their so-called "meticulous attention to detail" isn't just a slogan. They meant it. Byte by byte, line by line, they scrutinised everything. They found risks and edge cases that no one else did. The kind of issues that don't just slip past most teams, but past other auditors too. And here's the thing— BailSec doesn't bend. If your contract isn't up to their standards, they won't put their stamp on it…"
Developer behind @IntegrityDao, @0xVelvetai and @AVAXStrategies
"… What sets @bailsecurity apart is their meticulous approach. Their audits don't just identify vulnerabilities, they provide actionable solutions that strengthen the entire protocol. Even when code is technically sound, the BailSec team recognizes when design choices might cause unintended consequences for end users. This approach prevents issues that standard audits might miss. In the case of this new AVAX project, this would have benefited them drastically. Multiple teams and multiple auditors are assigned to each project, ensuring different perspectives. This approach best serves both users and clients by catching issues that a single auditor might overlook…"
"Can confirm from experience with @bailsecurity. Their audit quality is excellent and their ethical approach is rare in this space. Fair quotes and true focus on security"
"Over the last 3 years, we have worked with 10+ audit firms. It's an absolute delight any time an auditor exceeds our expectations. @bailsecurity worked with us recently and was very thorough with their feedback. @0xCharlesWang and the team were available 24/7 and got us through a tight deadline, too. Top-notch professionalism! 🔥 Would highly recommend them if you need quality auditors."
"Charles and Vik are among the best professionals I've ever had the pleasure of working with, both for their expertise and their human qualities. Their work has been flawless in every way: competent, responsive, precise, and honest. When it comes to security, I wouldn't trust anyone else. But what truly matters is that their work speaks for itself. There are no words to fully describe Bailsec - just read their reports, and you'll understand their value"
"We've been working with BailSec for a few months now, and they've been consistently top-notch security feedback, really acting like a solid gatekeeper for Lista DAO. Also, we actually got a refund from BailSec for an audit because the work finished faster than they originally expected. That's never happened before."
"The Bailsec team's exceptional ethics align with our recurring needs: flexibility, a tailored approach to product development, and limitless support. Prom and all the members of our ecosystem are grateful to Bailsec for their top-notch expertise and look forward to expanding our long-term commitments."
"Engaging with BailSecurity for a smart contract audit was a great experience all the way. Their focused approach and expertise in blockchain security provided us with valuable insights. This collaboration, demonstrated their professionalism and commitment to security in the DeFi space. We appreciate their contribution to enhancing our platform's integrity."
"After having built two protocols that rely 100% on the HyperliquidX Precompiles, I've come to realize that there's a fair bit of knowledge that has know built up in our team. Over the last few months that knowledge has been transfered to Bailsec as they audit our Tokenized HLP and Liquid Staking protocols. If you're protocol building with the Hyperliquid precompiles and you want an audit, reach out to them. They probably have the most knowledge around the Precompile infrastructure of any auditors in the space."
"… BailSec's experience, clear structure, and the way they look beyond just the surface of the code makes them incredibly valuable as a security partner … They take the time to understand how things are built, question design choices, and offer suggestions that actually improve the protocol overall. It feels more like working with a long-term partner than just a service provider. Their team always brings multiple people into a project, which means you get different perspectives and a more complete review. … If you are building something serious and want to be confident in what you are launching, BailSec is the team you want to talk to."
"At Algebra, we tried six audit companies over the past three years and finally found exactly what we needed. Many auditors focus only on standard patterns or weaknesses (like min/max or overflow), which doesn't suit Algebra, as we manage the liquidity infrastructure for many DEXes running on our CLAMM model. BailSec works differently — they start by understanding the full concept and architecture before diving deep into analysis. We're happy to recommend them to all DeFi projects, especially DEXes!"
"We have worked with many auditors over the years, but Bailsec truly stands out, especially when it comes to handling complex scopes and CLAMM. In this area, they are simply the best. Their ability to uncover deeply hidden, high-impact issues is exceptional. If you are serious about securing your project properly. We highly recommend working with this team"
"Working with Bailsec has been an excellent experience. Overall, tied with ToB for the most responsive auditing team. Responsiveness: 10/10 Thoroughness: 8/10 Skill: 9/10 Overall: 9/10"
