A python server for lightning zaps in the Nostr network, facilitating a self hosted LND instance behind Tor. Use it to set up a server to recieve lightning zaps in The Nostr. Go self custody - not your keys, not your coins :-) It's an alternative for Wallet Of Satoshi or getalby.com - but only for tec people.
⚠️ This is As-Is: It worked from 9/23 till 4/24 without bugs. Now it's not maintained in this repo anymore, may or may not work. I dev it at another place to be a zap-bank.
The protocol is documented in Nostr NIP-57 - my implementation looks like this:
- Be a server
- Provide a lnurl pay endpoint like in LUD-16, extended by the requirements in NIP-57
- Listen for zap requests kind 9734, REST - send them to the LND, proxy that requests with Tor socks5h
- Deliver the bech32-serialized lightning invoice to the wallet LUD-06
- Listen at REST LND for invoice updates
- Create the NIP-57 kind 9735 Event and deliver it to the relays.
You'll need a macaroon for your lnd. Bake it like
lncli bakemacaroon --save_to=./nip57macaroon invoices:write invoices:read
You'll need the onion address of your rest lnd interface, can find it usually in
/var/lib/tor/lnd/hostname
You'll need a tor proxy in SOCKS5H_PROXY. Use the docker compose if you don't have tor running on your host.
- create the users.json with the users you provide the service for
- cp the tls.cert from your lnd instance to here
- cp .env.example to .env and adjust the settings
Start up and test looks like this:

{"state":"SERVER_ACTIVE"}
The state request forwards to lnd rest /v1/state
Tor is sometimes slow, to slow for some zap clients like damus or Amethyst. With the Dial-Up Dyn-Ip feature, you can connect the nip57-server to lnd via clearnet.
Path for this is /lnurlp/set_clearnet?secret=xyz&ipv4=18.19.20.21&port=8080&tls_verify=False
The secret must be set in env.
Feel free to post issues or merge requests or zap me.
