PriFi - Private Finance revolution

Why Privacy?

It relates to an individual’s ability to determine for themselves when, how, and for what purpose their personal information is handled by others.

Protecting privacy is key to ensuring human dignity, safety and self-determination. It allows individuals freely develop their own personality.

Why DeFi?

DeFi opens up financial services to anyone with an internet connection, regardless of their geographic location or socio-economic background. Breaking gaps between individuals, it also eliminates the need for intermediaries and middlemen.
