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.

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
