With Cashu you can securely receive payments without an internet connection! 🥜🔏

Here is how it works:

1. The receiver sets up their wallet and chooses a mint (this is done while online). The wallet will download the mint’s key sets and save them locally

2. When the receiver wants to receive a payment (now being offline) the wallet will generate a payment request, specifying the amount, the locking script, and the mint.

3. The sender scans the payment request and constructs the requested token

4. The receiver receives the token. His wallet checks whether the token fulfils the requirements. Then it uses the included DLEQ proofs and the cached key set to verify whether the signature on the token is valid. If it is, the transaction is complete.
