# Awesome Cashu 🥜✨



A curated, collaborative list of awesome resources for getting ramped up with Cashu



## What's Cashu?



Cashu is a free and open-source Chaumian Ecash system built for Bitcoin. [Chaumian Ecash](https://en.wikipedia.org/wiki/Ecash) is an anonymous cryptographic electronic money or electronic cash system invented in 1982. Cashu is a modern ecash implementation on Bitcoin.
