About AdHash

We make transparency the default state of digital advertising. The AdHash Protocol cuts out the ad tech middlemen to bring efficiency, trust, and privacy. By doing so, we not only help independent publishers monetise much better the content they create, we also preserve users’ privacy and control over their browsing experience.
