 ## Status of the Fork:
-- NIP57 for Nostr (ZAPS) works when using an LNBits or LND backend, other backends (sparko, lnpay, eclair, commando) still need verification of payments in waitforinvoice.go by API calls in order to sign the zap on Nostr. (Help appreciated, because I can't test them)

 - Needs proper testing (especially in multi-user environment)
