Who trusts us

Halborn takes immense pride in being the trusted security advisor for leading names in blockchain and financial services industries. Our impressive roster includes notable crypto organizations such as Solana, Coinbase, Bored Ape Yacht Club, Ava Labs, Animoca, Dapper Labs, and many more.

Moreover, traditional financial institutions turn to us to secure their clients' digital assets and seamlessly integrate blockchain technology into their operations.

The trust placed in Halborn by these distinguished organizations is a testament to our unwavering commitment to safeguarding their digital endeavors, further reinforcing our position as the go-to security partner for those who demand nothing short of the best.

John Wu, President

AVA Labs

What sets Halborn apart is its extensive knowledge of best security practices inside and outside of the blockchain industry. With the pen test report on the Avalanche Wallet, Halborn led with the highest level of professionalism and extreme care with every last detail.

Siggi Óskarsson, CTO

BSV Association

The thing that stood out for me was a very big click about the mentality and the way to approach the projects. Being very agile and open and collaborative, and looking at this as a partnership. I think that was the biggest selling point for me. It’s not like we are doing this SOW for three months and then after the three months we will evaluate, no, we are doing that each week and talking about it continuously and steering in a different direction if necessary halfway through the project. That flexibility and agility was the key for me.

Larin Krämer, Functional Lead, Digital Assets Infrastructure

Bank Frick

Working with Halborn underlined our commitment to security, transparency, and ongoing excellence in digital asset custody. Their advanced approach to key ceremony auditing supported our mission to set industry-leading standards as a trusted blockchain bank

Shaun Martinak, Researcher, Portfolio Manager

Coinbase Asset Management

As we searched for security partners, Halborn quickly rose to the top of that list because of their experience working across a range of technology stacks and having the deep experience to be able to integrate decentralized networks, cryptographic computing into that broader vision, and to help us test all aspects of it.

Brendon Sedo, Contributor

Core DAO

Our strategy on security is to get to work with the best partners—you being one of them, as Halborn has a great reputation and do a lot of diligence with these partners. We took a lot of time to make sure that everything was built right because we take security really seriously.

Jon Eichhorn, Risk Director

Crossmint

Halborn provides a quality review process and a positive experience throughout the engagement while performing an in-depth technical analysis. Their review gives us additional comfort in our solutions, knowing they have been audited by a qualified, independent organization.

Inder Singh, VP of Product/Tech

D3 Inc

The largest registrars trust the Doma platform to bring the $360B+ asset class onchain. Security is paramount, and Halborn ensures the infrastructure is production ready.

Robert Bryan, Founder

Karate Combat

We thought you were so much better, technically, than the other firms. But just looking at your general processes and the amount of time you are spending versus the other offerings out there, we thought it made a lot of sense because it's very important: we have a very valuable asset that is now going into this structure, and we want to make sure it's entirely secure.

Michael Steuer, Co-Founder & CTO

MAKE

Halborn has a tremendous reputation and track record. We had heard from other projects that we are close with about the great experience they had with Halborn. So, after learning more about Halborn's approach to auditing, it was really a done deal.

James Poole, Founding Contributor

Renzo

Halborn has been a tremendous resource on the security side as Renzo has evolved from a simple initial protocol to a multi-chain ecosystem. They have been a true partner with our product and users being the ultimate beneficiary of their hard work and dedication.

Kenny Lei, Engineering Manager

Ripple

Halborn brought immediate value from day one, rapidly understood the XRP Ledger architecture, and delivered clear, actionable insights that strengthened the security of our new features.

Brandon Truong, Head of Product

Zetachain

With audits there's real work, and it's represented by the reputation Halborn has. And from some of the people we had talked to, who have worked with you before, it seemed like a perfect fit because you aren't just specialized on smart contracts. I think it really helped in making a decision to work with Halborn: a comprehensive partner we can work with even beyond Mainnet.
