The standard for secure decentralized systems

Zeppelin builds tools for the secure development, deployment and operation of decentralized systems. We also help companies secure their systems by performing security audits.


The challenges of building decentralized systems


Economies where software powers real money are exposed to hacks and attacks.

Developer experience

Lack of proper development and testing tooling increases margin of errors exponentially.


It’s difficult to manage and fix problems in decentralized systems once deployed.
