This GUI allows liquidity consumers to buy from LSPs or nodes that advertise liquidity and listen for purchases requests using: https://github.com/smallworlnd/publsp.
How does it work?LSPs advertise liquidity as addressable Kind 39735 events. Anyone interested in purchasing liquidity from an LSP can just pull and evaluate all those structured events, then NIP-17 DM an LSP of their choice to coordinate a liquidity purchase. Liquiditystr just performs the customer side of things in a streamlined UI. It connects to Nostr relays, pulls Kind 39735 events, displays the ads, and pipes NIP-17 DMs between your session and the LSP. Have a look at the source code to get a better idea!
