About D23E

Blockchain security research & audits since 2014

Since 2014, we’ve worked at the intersection of blockchain and cybersecurity—researching real-world attacks, building tools, and helping teams ship safer systems. We optimize for consistent excellence: rigorous methods, clear communication, and pragmatic results.

As a security research and consulting firm, we partner with teams on their hardest security challenges by developing new technology, exploring techniques that move the state of practice forward, and reviewing systems before they go live.

We also help organize DeFi Workshop ↗.
