 # cashu
 
-**The author is NOT a cryptographer and has not tested the libraries used or the code nor has anyone reviewed the work. This means it's very likely a fatal flaw somewhere. This is meant only as educational and is not production ready.**
+**Cashu is a Chaumian Ecash wallet and mint with Bitcoin Lightning support.**
 
-Ecash implementation based on David Wagner's variant of Chaumian blinding. Token logic based on [minicash](https://github.com/phyro/minicash) ([description](https://gist.github.com/phyro/935badc682057f418842c72961cf096c)) which implements a [Blind Diffie-Hellman Key Exchange](https://cypherpunks.venona.com/date/1996/03/msg01848.html) scheme written down by Ruben Somsen [here](https://gist.github.com/RubenSomsen/be7a4760dd4596d06963d67baf140406). The database mechanics and the Lightning backend uses parts from [LNbits](https://github.com/lnbits/lnbits-legend).
