Non-custodial by design
zapsats.ca never receives LND macaroons or private keys. The local zapsats-broker signs claims with your node identity, keeps the outbound WebSocket open, and asks your lnSwitchboard instance to mint invoices.
Self-hosted Lightning Addresses
alice@zapsats.ca, routed by your own node.
Register a zapsats.ca handle from lnSwitchboard on Umbrel. zapsats.ca handles billing, renewal state, privacy-preserving routing, NIP-05, and LNURL discovery while your own LND node creates the receiving invoices.

Public channels required
Before registration and before invoice creation, the broker checks that your node has a public channel with enough inbound liquidity to receive the requested payment.
Private routing surface
Wallets talk to zapsats.ca. Your node connects outbound to agent.zapsats.ca, so your home IP and node endpoint are not exposed through the public Lightning Address flow.
Umbrel flow
Register from inside lnSwitchboard.

- 2Install lnSwitchboard.
- 3Ensure the zapsats-broker package is included and running.
- 4Open lnSwitchboard and choose Register zapsats.ca handle.
Privacy and safety
Billing state at the edge, custody at your node.
- One paid 30,000 sat invoice can activate or renew exactly one handle.
- The owner LND node pubkey is the root ownership identity.
- Nostr mappings store public npub/pubkey and relays only, never nsec keys.
- Raw IP addresses and contact emails are not stored in plaintext.
- After expiry, the 45-day grace window reserves the handle but blocks incoming Lightning payments.
