things we do
Design Bitcoin Security Products
We built Revault (Bitcoin custody for organisations), Liana (Bitcoin wallet leveraging on-chain timelocks), and more to come.
Protocol and Architecture Reviews
We have many years of experience designing security protocols, we offer security advice and reviews for other projects.
Bitcoin Core and Open Source Contributions
We strongly believe in Open Source, especially for security. We contribute to Bitcoin Core and other projects, and we open source our security products too.
Code Audits
We work with multiple security-focused developers capable of reviewing code and find weaknesses before someone malintentionned can.
Responsible Disclosures
We are very good at breaking things. We often find vulnerabilities and report them following the best practices around responsible disclosures. We love bug bounties!
Operational Security Advice and Assessments
Mapping risks and threats, suggesting mitigations and giving our opinion on your operational security.
