This service currently uses "fakewallet" instead of connecting to a Lightning node so it's only suitable for developers at the moment. If there are any additional settings you would like to be made available whilst testing please get in touch. Support for nodes is coming soon.

Introduction

Digital payments should be as natural as handing over cash in person. Cashu brings simplicity back to online payments.

Cashu is a free and open-source Chaumian ecash protocol built for Bitcoin. A digital bearer token that is stored on a user's device, very similar to physical cash. The Cashu protocol allows you to build applications such as wallets or voucher systems. Transactions are instant and nearly free.

Cashu is an ecash protocol that is integrated with the Bitcoin protocol. An ecash system consists of two parts, the mint and the wallet. Anyone can run a mint for their application, be it a wallet, a web paywall, paid streaming services, or a voucher and rewards system for a super market.

Ecash transactions between users or service providers respect the user's privacy. A mint does not store a database of user accounts and their activity which protects users from leaks or hacks and can provide stronger censorship resistance than classical payment systems.
