How does it work?

npub.cash uses Cashu-Address, a protocol built on Cashu and nostr. Cashu-Address allows a web server to provide Lightning addresses and mint ecash form the user's preferred Cashu mint. The user then redeems the ecash when they come back online.

A more detailed documentation as well as a guide to get started can be found on our Documentation Page.

Drag to move around

1. Lightning Payment

Alices sends a Lightnin Payment to Bob's Cashu-Address

2. Minting

Cashu-Address forwards the payment to the Mint. The Mint creates eCash locked to Bob's public key and returns it to Cashu-Address.

3. Claiming

Once Bob is back online, he checks for waiting payments and claims them with his Cashu Wallet
