Do you want to send and recieve lightning payments with your server with no lightning node liquidity management and no KYC lightning service provider accounts? - Yes, so do I. Does it drive you nuts that to make your software's payment interface fully sovereign and KYC-free on the lightning network, you need it to have practically 100% uptime. - This problem is solved. CashU solves these problems, but how do you do it with a headless system? - This is how. I wrote this to make my life easier. Maybe yours too. Run a systemd daemon, nutshell-walletd.service, on your server under a unique system user, store CashU tokens on the filesystem with permissions only accessible through the API and by the superuser. There are no network leaks, you access it exclusively through a permissioned Unix domain socket. There are three simple operations, the design is minimalistic: 1) get wallet balance. 2) get lightning invoice to be paid into wallet. 3) pay lightning invoice from wallet balance. Operations 2 and 3 involve two additional calls to complete and monitor the transaction status. It is documented in the API specification. Take a look at this document. The code is fully operational in the associated branch, I am using it with a custom lnbits funding source. https://github.com/BrunswickBTC/nutshell/blob/BrunswickBTC_Wallet_FastAPI_UDS/walletd_UDS_API.md
