Founding and Mission
Hack-a-Chain was founded in 2022 by three young entrepreneurs as a security audit and software development company specialized in blockchain technology. We rapidly evolved into a laboratory for high-tech experiments focused primarily in data privacy.
Our products were bootstrapped and partially awarded grants from major blockchain players, such as Near Protocol, Phala Network and Kadena.
Our end goal is to reduce financial losses and increase system’s security by reducing unwanted data leakages from design failure. We envision doing that by combining advanced cryptographic techniques to provide control over data flow. Contact us for cooperation!
