Send & Receive Payments

The Lightning Wallet card on the home page is the entry point for both flows.

1. Click Receive on the Lightning Wallet card.

2. Keep the payment type on Invoice (the default; Offer creates a reusable BOLT12 offer instead — see BOLT12 Offers).

3. Enter a Description (required) and an Amount in sats. Leaving the amount empty creates an open (any-amount) invoice. The fiat equivalent is previewed under the amount field.

4. Click Send Payment. On success the app shows a green alert with the payment hash:

   

5. The outgoing payment shows up in the Transactions list with a Created at timestamp and a negative amount:
