Context

The API currently runs in LNBits stub mode. For production, connect to a real
Lightning node.

Requirements

Provision or use existing Bitcoin + LND + LNBits infrastructure
The infrastructure/ directory in this repo has everything needed
Run setup.sh on a DO droplet to bootstrap the node
Configure API env vars: LNBITS_URL, LNBITS_API_KEY
Test real invoice creation and payment flow
Configure cold storage sweep to Alexander's hardware wallet

Steps

Provision DO droplet (4GB+ RAM for bitcoind IBD)
Run infrastructure/setup.sh
Wait for Bitcoin sync (2-3 days for IBD)
Initialize LND wallet
Fund LND with on-chain BTC
Open Lightning channels (need inbound liquidity)
Configure LNBits wallet
Point API at LNBits

Acceptance Criteria

bitcoind fully synced on mainnet
LND node running with channels
LNBits connected to LND
API creates real invoices
Test payment flows through successfully
Cold storage sweep configured

## Context The API currently runs in LNBits stub mode. For production, connect to a real Lightning node. ## Requirements - Provision or use existing Bitcoin + LND + LNBits infrastructure - The `infrastructure/` directory in this repo has everything needed - Run `setup.sh` on a DO droplet to bootstrap the node - Configure API env vars: `LNBITS_URL`, `LNBITS_API_KEY` - Test real invoice creation and payment flow - Configure cold storage sweep to Alexander's hardware wallet ## Steps 1. Provision DO droplet (4GB+ RAM for bitcoind IBD) 2. Run `infrastructure/setup.sh` 3. Wait for Bitcoin sync (2-3 days for IBD) 4. Initialize LND wallet 5. Fund LND with on-chain BTC 6. Open Lightning channels (need inbound liquidity) 7. Configure LNBits wallet 8. Point API at LNBits ## Acceptance Criteria - [ ] bitcoind fully synced on mainnet - [ ] LND node running with channels - [ ] LNBits connected to LND - [ ] API creates real invoices - [ ] Test payment flows through successfully - [ ] Cold storage sweep configured ## References - Parent epic: #{epic_num} - Infrastructure scripts in `infrastructure/`

The infrastructure scripts already covered the full node provisioning flow. This PR closes the API-side configuration gap:

.env.example — documents LNBITS_URL, LNBITS_API_KEY and all other required env vars; operators copy values printed by lnd-init.sh
GET /api/healthz — now returns lnbits_stub: bool and lnbits_url so operators can verify real Lightning connectivity at a glance
Production startup warning — loud WARN log if LNBITS_URL/LNBITS_API_KEY are absent in NODE_ENV=production

Switching from stub to real mode requires only setting those two env vars after running infrastructure/lnd-init.sh on the droplet.
