Dockerized lnurl-commando 📦

An easily configurable docker instance of a lnurl server that fetches invoices over the lightning network via lnsocket¹ and commando².

Why?

This dockerized version of lnurl-commando was built to enable LNURL payments on Core Lightning nodes in the form of [email protected]. This is commonplace with LND but core lightning lnurl support right now is not overt. This repo solves this.

lnurl-commando in this version enables zaps on nostr for Core Lightning users.
