+# AGENTS.md - AI Coding Agent Guide for LNbits
+
+This file guides AI coding agents working on LNbits. Keep changes small, verified, and aligned with existing project patterns.
+
+## Core Behavior
+
+- Think before coding. State material assumptions. Ask when ambiguity affects correctness, security, payments, wallets, or data migrations.
+- Prefer the simplest implementation that solves the request.
+- Make surgical changes. Every changed line should trace back to the task.
+- Do not refactor, reformat, rename, or clean adjacent code unless required.
+- Remove only dead code or imports created by your own changes.
+- Define success criteria for non-trivial work and verify them before reporting done.
+
+## LNbits Architecture
+
+- Keep core lean. Prefer/assess extensions for non-core features.
+- Preserve compatibility with existing extensions and wallet backends.
+- Follow existing patterns in `lnbits/core`, `lnbits/wallets`, `lnbits/extensions`, and frontend code.
+- Use existing CRUD, services, settings, and migration patterns.
+- Do not edit generated files, bundled vendor files, or unrelated extension code.
+
+## Security-Sensitive Areas
+
+Be extra cautious with payments, wallet balances, admin routes, keys, LNURL, Bolt11, funding sources, migrations, and authentication.
+
+Do not expose raw stack traces or sensitive values. Do not add synchronous blocking work in hot async paths without justification.
+
+## Commands and Verification
+
+Read `Makefile` before running project commands.
+
+Use Makefile targets instead of hand-written commands when available:
+
+- `make check` for full checks.
+- `make test-unit` for unit tests.
+- `make test-api` for API tests.
+- `make test-wallets` for wallet tests.
+- `make checkbundle` when bundled frontend assets may be affected.
+- `make format` only when formatting is intended.
+
+Do not run `make test` by default. Use the targeted tests available in the Makefile that are related to the work done, unless the user explicitly asks for broader test coverage.
+
+## Dependencies
+
+Do not add dependencies without approval. If approved, update the correct project files and explain why the dependency is necessary.
+
+## Maintenance
+
+LNbits maintainers own this file. They should update it when the development workflow, architecture, or verification commands materially change.
+
+Do not edit, commit, push, or include changes to this file in a PR as part of normal feature work unless the user explicitly asks for `AGENTS.md` changes.
+
+## Reporting
+
+When finished, report:
+
+- Summary of what changed.
+- Files touched.
+- Makefile targets or checks run.
+- Anything not verified and why.

+# Generic OIDC Authentication Configuration
+
+This document explains how to configure generic OIDC authentication for LNbits, which allows integration with various OIDC-compliant authentication providers such as Zitadel, Authentik, and others.
+
+## Overview
+
+The generic OIDC provider (`oidc`) complements the existing Keycloak provider and allows you to integrate any OIDC-compliant authentication service. You can customize the login button with your own organization name and icon.
+
+## Configuration
+
+Add the following environment variables to your `.env` file or system environment:
+
+### Required Settings
+
+```bash
+# Enable OIDC authentication
+LNBITS_AUTH_ALLOWED_METHODS=oidc-auth
+
+# OIDC Discovery URL (well-known endpoint)
+LNBITS_OIDC_DISCOVERY_URL=https://your-oidc-provider-domain/.well-known/openid-configuration
+
+# Client credentials from your OIDC provider
+LNBITS_OIDC_CLIENT_ID=your-client-id
+LNBITS_OIDC_CLIENT_SECRET=your-client-secret
+```
+
+### Optional Settings - Customize the Login Button
+
+You can customize how the OIDC login button appears to your users:
+
+```bash
+# Custom organization name (displayed on the login button)
+# Example: "Login via Zitadel" or "Login via Authentik"
+LNBITS_OIDC_CLIENT_CUSTOM_ORG="Zitadel"
+
+# Custom icon URL (displayed on the login button)
+# Can be a full URL or a path to a local image
+LNBITS_OIDC_CLIENT_CUSTOM_ICON=https://zitadel.com/favicon.svg
+```
+
+If not set, the button will display "Login via OIDC" with a generic lock icon.
+
+## Zitadel Configuration Example
+
+For Zitadel, configure as follows:
+
+1. Create a new application in Zitadel
+2. Choose "Web" application type
+3. Configure the redirect URI: `https://your-lnbits-domain/api/v1/auth/oidc/token`
+4. Save the Client ID and Client Secret
+5. Use these environment variables:
+
+```bash
+LNBITS_AUTH_ALLOWED_METHODS=oidc-auth
+LNBITS_OIDC_DISCOVERY_URL=https://your-oidc-provider-domain/.well-known/openid-configuration
+LNBITS_OIDC_CLIENT_ID=your-zitadel-client-id
+LNBITS_OIDC_CLIENT_SECRET=your-zitadel-client-secret
+# Customize the button to show "Login via Zitadel" with Zitadel's logo
+LNBITS_OIDC_CLIENT_CUSTOM_ORG="Zitadel"
+LNBITS_OIDC_CLIENT_CUSTOM_ICON="https://zitadel.com/favicon.svg"
+```
+
+**Result**: The login page will display a button with the text "Login via Zitadel" and the Zitadel logo.
+
+## Authentik Configuration Example
+
+For Authentik:
+
+1. Create a new OAuth2/OpenID Provider
+2. Set the redirect URI: `https://your-lnbits-domain/api/v1/auth/oidc/token`
+3. Configure scopes: `openid`, `email`, `profile`
+4. Get the Client ID and Client Secret
+
+```bash
+LNBITS_AUTH_ALLOWED_METHODS=oidc-auth
+LNBITS_OIDC_DISCOVERY_URL=https://authentik.yourdomain.com/application/o/your-app/.well-known/openid-configuration
+LNBITS_OIDC_CLIENT_ID=your-authentik-client-id
+LNBITS_OIDC_CLIENT_SECRET=your-authentik-client-secret
+LNBITS_OIDC_CLIENT_CUSTOM_ORG="Authentik"
+```
+
+## Multiple Auth Methods
+
+You can enable multiple authentication methods simultaneously:
+
+```bash
+LNBITS_AUTH_ALLOWED_METHODS=username-password,oidc-auth,keycloak-auth
+```
+
+## Discovery Endpoint Requirements
+
+Your OIDC provider must expose a standard discovery endpoint (`.well-known/openid-configuration`) that includes:
+
+- `authorization_endpoint`
+- `token_endpoint`
+- `userinfo_endpoint`
+- `jwks_uri` (JSON Web Key Set)
+
+The OIDC implementation will automatically fetch these endpoints from the discovery URL.
+
+## User Mapping
+
+The OIDC provider maps user information from the OIDC userinfo endpoint:
+
+- `sub` → User ID
+- `email` → Email address
+- `given_name` → First name
+- `family_name` → Last name
+- `name` or `preferred_username` → Display name
+- `picture` → Profile picture URL
+
+## Troubleshooting
+
+### Authentication fails
+
+1. Verify the discovery URL is accessible
+2. Check that Client ID and Client Secret are correct
+3. Ensure redirect URI in your OIDC provider matches: `https://your-lnbits-domain/api/v1/auth/oidc/token`
+4. Check LNbits logs for detailed error messages
+
+### User info not populated
+
+Some OIDC providers may use different claim names. If user information is not correctly populated, check your provider's userinfo endpoint response format and adjust the provider class if needed.
+
+## Security Considerations
+
+- Always use HTTPS in production
+- Keep client secrets secure and never commit them to version control
+- Use environment variables or secure configuration management
+- Regularly rotate client secrets
+- Review OIDC provider's security best practices
+
+## Implementation Details
+
+The OIDC provider is implemented in `lnbits/core/models/sso/oidc.py` and extends the `fastapi_sso` library's `SSOBase` class. It uses the standard OpenID Connect flow with:
+
+- Scopes: `openid`, `email`, `profile`
+- Response type: `code` (authorization code flow)
+- Discovery document for automatic endpoint resolution

+## Spark L2
+
+Self-custodial funding source using the [Spark L2](https://docs.spark.money/start/overview) network. Requires a Node.js [sidecar](https://github.com/lnbits/spark_sidecar) that bridges lnbits talking to Spark. Works in addition with any Spark-compatible seed (Wallet of Satoshi, BuhoGO, BlitzWallet).
+If the sidecar is started with a `mnemonic` then that mnemonic will be used. Otherwhise if a mnemonic is set for the `Spark L2` LNbits funding source then that mnemonic will be used.
+
+### Optional tuning
+
+- `SPARK_L2_PAY_WAIT_MS`: `4000` _(payment timeout in ms)_
+- `SPARK_L2_PAY_POLL_MS`: `500` _(polling interval in ms)_
+- `SPARK_L2_STREAM_KEEPALIVE_MS`: `15000` _(SSE keepalive in ms)_
+
+### Example: run the sidecar
+
+```bash
+git clone https://github.com/lnbits/spark_sidecar.git
+cd spark_sidecar
+npm install
+
+SPARK_MNEMONIC="bottom bottom bottom bottom bottom bottom bottom bottom bottom bottom bottom bottom" \
+SPARK_NETWORK=MAINNET \
+SPARK_SIDECAR_PORT=8765 \
+SPARK_PAY_WAIT_MS=20000 \
+node server.mjs
+```
+
+For testing, you can generate a 12-word mnemonic at https://iancoleman.io/bip39/. Store it securely — it controls your funds. Then select Spark (L2) as the funding source in LNbits.
