From 5b0e0e0d9185657fa5fb59f30c00df7e9a19f9b9 Mon Sep 17 00:00:00 2001 From: Patrick Mulligan Date: Sat, 24 Jan 2026 18:05:00 -0500 Subject: [PATCH] Fix Lightning.Pub RPC integration for e2e cash-in flow Major fixes: - Implement NIP-44 v1 encryption (Lightning.Pub requirement) - Fix RPC request format (rpcName, params, query, body, authIdentifier, requestId) - Fix PayInvoice amount field (always required, use 0 for invoices with amounts) - Fix NostrClient subscriptions to use direct Relay instead of SimplePool - Fix race condition by subscribing before publishing requests - Remove #p/#e tag filters and match manually (relay compatibility) New features: - Add CLINK Debit support to cash-in flow - Add invoice paste input for manual payments - Add Input UI component Documentation: - Add TROUBLESHOOTING.md with 6 non-obvious integration gotchas - Update CLAUDE.md with reference to troubleshooting doc Test scripts: - fund-dev.mjs - Create invoices for testing - test-pay.mjs - Test PayInvoice RPC directly Co-Authored-By: Claude Opus 4.5 --- lamassu-next/CLAUDE.md | 4 + .../machine/src/components/ui/input/Input.vue | 35 ++ .../machine/src/components/ui/input/index.ts | 1 + .../apps/machine/src/services/lightning.ts | 133 ++++--- .../machine/src/services/lnurl-withdraw.ts | 310 ---------------- lamassu-next/apps/machine/src/stores/atm.ts | 119 ++++++ .../apps/machine/src/views/CashInView.vue | 200 +++++++++-- lamassu-next/docker/docker-compose.dev.yml | 3 +- .../packages/lightning/TROUBLESHOOTING.md | 339 ++++++++++++++++++ lamassu-next/packages/lightning/src/client.ts | 121 +++++-- lamassu-next/packages/lightning/src/index.ts | 2 + lamassu-next/packages/lightning/src/types.ts | 30 +- .../packages/nostr-client/fund-dev.mjs | 109 ++++++ .../packages/nostr-client/package.json | 10 +- .../packages/nostr-client/src/client.ts | 43 ++- .../packages/nostr-client/src/encryption.ts | 275 ++++++++++++-- .../packages/nostr-client/test-pay.mjs | 114 ++++++ lamassu-next/pnpm-lock.yaml | 52 ++- 18 files changed, 1419 insertions(+), 481 deletions(-) create mode 100644 lamassu-next/apps/machine/src/components/ui/input/Input.vue create mode 100644 lamassu-next/apps/machine/src/components/ui/input/index.ts delete mode 100644 lamassu-next/apps/machine/src/services/lnurl-withdraw.ts create mode 100644 lamassu-next/packages/lightning/TROUBLESHOOTING.md create mode 100644 lamassu-next/packages/nostr-client/fund-dev.mjs create mode 100644 lamassu-next/packages/nostr-client/test-pay.mjs diff --git a/lamassu-next/CLAUDE.md b/lamassu-next/CLAUDE.md index 045052b..4aacac4 100644 --- a/lamassu-next/CLAUDE.md +++ b/lamassu-next/CLAUDE.md @@ -54,6 +54,10 @@ lamassu-next/ - **apps/dashboard** - Operator dashboard for fleet management - **packages/hal** - Rust hardware drivers (bill validators, dispensers, printers) +### Critical Documentation + +- **`packages/lightning/TROUBLESHOOTING.md`** - Lightning.Pub integration gotchas.
