I built Freeport - a P2P marketplace over Nostr with a built-in self-custodial Lightning wallet

Freeport is a P2P marketplace (rides, services, goods) running entirely on Nostr relays - no server, no middleman. It now has payments built in:

- Self-custodial Lightning (Breez SDK / Spark) - the app never holds funds

- Wallet key derived from your Nostr key: one backup covers identity + wallet

- No signup - keypair generated on-device, optional passkey login

- Lightning address, bolt11, on-chain

- Confirmed deals get a Pay button / QR with the agreed amount, auto-converted from fiat

Fun fact: you can download the HTML file from releases page to run the whole app ????
