Cashu is a Chaumian Ecash wallet and mint with Bitcoin Lightning support.

Disclaimer: The author is NOT a cryptographer and this work has not been reviewed. This means that there is very likely a fatal flaw somewhere. Cashu is still experimental and not production-ready.

Cashu is an Ecash implementation based on David Wagner’s variant of Chaumian blinding. Token logic based on minicash (description) which implements a Blind Diffie-Hellman Key Exchange scheme written down by Ruben Somsen here. The database mechanics and the Lightning backend uses parts from LNbits.

Please read the Cashu documentation.
