Digital Cash

OpenCash supports projects building on the Cashu protocol. We believe that digital cash infrastructure should be free and open-source and accessible to everyone.


Our quest for digital cash

Our mission is to provide sustainable support for free and open-source development of digital cash projects building on the Cashu protocol. Cashu is a Chaumian Ecash protocol that provides a scalable, and efficient, and privacy-respecting digital cash system for Bitcoin and the broader financial ecosystem.

Digital cash will likely play a crucial role in the design of payment infrastructure and other financial services in the future. We therefore believe that the development of these systems should be in the public domain and free to use for everyone. You can learn more about the Cashu protocol here.

Your donation makes a difference

We provide funding to developers through our grants program, and we support the broader Cashu ecosystem through our research and events. All projects that we support are open-source and free to use.
