* fix: use semantic author for zap targeting
When zapping certain event kinds (zaps, streams), use the semantic
author instead of event.pubkey:
- Zaps (9735): Target the zapper, not the lightning service
- Streams (30311): Target the host, not the event publisher
Changes:
- Extract getSemanticAuthor() to shared utility (src/lib/semantic-author.ts)
- Update BaseEventRenderer to use semantic author when opening zap dialog
- Update ZapWindow to resolve recipient using semantic author
- Refactor DynamicWindowTitle to use shared utility
This ensures that when you zap an event, you're zapping the right person
(the one who semantically "owns" or created the event), not just whoever
signed it.
* fix: load event in DynamicWindowTitle to derive zap recipient
When opening a zap dialog via 'zap naddr1...' or 'zap nevent1...', the
window title was showing "ZAP" instead of "Zap {host name}" because
DynamicWindowTitle only had access to the empty recipientPubkey from
the initial props.
Now DynamicWindowTitle:
- Loads the event from eventPointer if present
- Derives the recipient using getSemanticAuthor() if recipientPubkey is empty
- Falls back to explicit recipientPubkey if provided
This ensures the window title shows the correct recipient name
immediately, matching the behavior in the ZapWindow component itself.

* feat: add NIP-57 zap command foundation
Implements the foundational structure for sending Lightning zaps (NIP-57) to
Nostr users and events. This commit adds the command interface, UI components,
and routing logic. The actual LNURL resolution and zap request creation will
be implemented in follow-up commits.
Components Added:
- ZapWindow: Full-featured UI for zapping with amount presets, custom amounts,
wallet integration, and QR code fallback
- parseZapCommand: Parser supporting multiple formats (npub, nprofile, nevent,
naddr, NIP-05, $me alias)
- Command registration in man pages with examples
- Window routing and title generation
Features:
- Preset amount buttons (21, 100, 500, 1000, 5000, 10000 sats)
- Custom amount input
- Amount usage tracking (remembers most-used amounts)
- Comment field for zap messages
- Event context rendering (shows zapped event in UI)
- Dual payment methods: NWC wallet or QR code/invoice copy
- Dynamic recipient resolution (from event author if zapping event)
Usage:
zap fiatjaf.com # Zap a user by NIP-05
zap npub1... # Zap a user by npub
zap nevent1... # Zap an event (recipient = author)
zap npub1... nevent1... # Zap specific user for specific event
Next Steps:
- Implement LNURL-pay resolution (fetch callback URL and nostrPubkey)
- Create kind 9734 zap request event with applesauce factory
- Implement invoice generation via LNURL callback
- Integrate NWC wallet payment
- Add zap action to event context menus
- Implement zap receipt listening (kind 9735)

- Validate zap support (allowsNostr, nostrPubkey)
- Fetch invoices from LNURL callbacks with zap requests
- Amount validation (min/max sendable)
- Comment length validation
2. **Zap Request Creation** (src/lib/create-zap-request.ts)
- Build kind 9734 zap request events using applesauce EventFactory
- Sign with user's active account
- Include recipient (p tag), amount, relays, optional event context (e/a tags)
- Serialize to URL-encoded JSON for LNURL callbacks
- Smart relay selection (user's inbox relays for zap receipts)
3. **ZapWindow Complete Flow** (src/components/ZapWindow.tsx)

- Fix authorProfile: call getProfileContent on NostrEvent, not on ProfileContent
- Fix lud16/lud06 access: use recipientProfile directly
- Fix success toast: use recipientProfile?.name instead of content?.name
All type errors resolved. ProfileContent is returned by useProfile, not NostrEvent.
* feat: refine ZapWindow UI and add dynamic window title
UI Refinements per user request:
- Remove QrCode unused import
- Simplify payment flow to single adaptive button

All tests passing (939 passed)
Build successful
* fix: open LoginDialog instead of connection window for zap login
Changes:
- Import LoginDialog component into ZapWindow
- Add showLogin state to control LoginDialog visibility
- Update handleLogin to open LoginDialog instead of connection window
- Remove unused useGrimoire import and addWindow destructuring
- Add LoginDialog component to render alongside QR dialog
User Experience:

- Users can log in with extension, readonly, nsec, or NIP-46
- After login, user can proceed with zap flow
- More intuitive than opening relay connection window
All tests passing (939 passed)
Build successful
* feat: auto-close ZapWindow after successful wallet payment
Changes:
- Add onClose callback prop to ZapWindowProps interface
- Pass onClose from WindowRenderer to ZapWindow component
- Call onClose() with 1.5s delay after successful wallet payment
- Allow user to see success toast before window closes
User Experience:
- After zapping with wallet, window automatically closes
- 1.5 second delay allows user to see success message
- Prevents accidental double-zapping
- Cleaner flow - no manual window closing needed
Implementation:
- WindowRenderer passes onClose callback to ZapWindow
- ZapWindow calls onClose after payment success and toasts
- setTimeout(onClose, 1500) provides brief delay for UX
- QR code path unchanged (window stays open for payment)
All tests passing (939 passed)
Build successful
* feat: full-width custom amount and wallet timeout with QR fallback
Custom Amount Input:
- Change custom amount input from w-24 to flex-1
- Now takes full remaining width in flex row
- Better UX on smaller screens and more obvious input field
Wallet Payment Timeout Handling:
- Add 30 second timeout to wallet payments using Promise.race
- On timeout, automatically show QR code as fallback
- Add paymentTimedOut state to track timeout condition
- Toast warning when payment times out
Retry with Wallet Feature:
- Add handleRetryWallet function to retry timed out payment
- Show "Retry with Wallet" button in QR dialog when timed out
- Button only appears if wallet is connected and payment capable
- Retry uses same 30s timeout, shows error if fails again
- Provides loading state with spinner during retry
User Flow:
1. User attempts wallet payment
2. If timeout after 30s, shows QR code automatically
3. User can scan QR to pay manually OR
4. User can click "Retry with Wallet" to try again
5. If retry times out, stays on QR for manual payment
Implementation Details:
- Promise.race between payInvoice and 30s timeout
- Timeout throws Error("TIMEOUT") for easy detection
- QR dialog conditionally shows retry button
- Retry resets state and attempts payment again
- Console logging for debugging timeout issues
All tests passing (939 passed)
Build successful
* feat: production-ready zaps with manual close and profile integration
Payment Flow Improvements:
- Remove auto-close after successful payment
- Change "Zap Sent!" button to "Done" button that requires user click
- User must manually close window by clicking Done after payment
- Retry payment also requires manual close after success
Profile Viewer Integration:
- Add Zap icon next to lightning address in ProfileViewer
- Click zap icon to open ZapWindow for that profile
- Yellow icon with hover effect for visual feedback
- Integrates seamlessly with existing profile UI
Production Cleanup:
- Remove all debug console.log statements
- Keep console.error for production error logging
- Remove unused emojiService variable from useEmojiSearch
- Fix Loader2 className typo (animate-spin)
- Clean code ready for production deployment
User Experience:
1. View profile with lightning address
2. Click yellow zap icon to open zap window
3. Enter amount and optional comment
4. Pay with wallet (or QR code if timeout)
5. See success message
6. Click "Done" to close window (manual control)
Testing:
- All lint checks pass (no errors, only warnings)
- TypeScript build successful
- All 939 tests passing
- Production-ready code
Code Quality:
- No debug logging in production
- Proper error handling maintained
- Clean, maintainable code
- Follows project conventions
* fix: remove duplicate zapTitle condition in DynamicWindowTitle
Removed duplicate zapTitle if-else branch at line 870 that was causing
lint error. The first zapTitle condition at line 803 handles all cases,
making the second occurrence unreachable.
* feat: improve zap UX with inline QR and faster imports
- Move imports to top level instead of dynamic imports for faster resolution
- Show QR code inline in ZapWindow instead of separate dialog
- Show recipient name and address when not zapping an event
- Make Lightning address clickable in ProfileViewer with icon on left
- Use recipientName consistently throughout zap flow
This significantly reduces the "Resolving Lightning address..." delay and
provides a cleaner, more integrated UX for viewing and paying invoices.
* feat: optimize zap UX with better error handling and UI improvements
LNURL improvements:
- Add 10s timeouts to Lightning address resolution and invoice fetching
- Better error messages with more context (response status, error text)
- Handle AbortError for timeout scenarios
UI improvements:
- Bigger amount buttons (default size instead of sm)
- Custom amount on separate line for better layout
- Disable all zap UI when recipient has no Lightning address
- Show clear warning when Lightning address is missing
- Only show comment editor when Lightning address is available
Toast cleanup:
- Remove chatty info toasts ("Resolving...", "Creating...", "Fetching...")
- Only show errors and success messages
- Cleaner, less noisy UX
This addresses common issues with LNURL requests timing out and makes
the UI more responsive and informative when zaps cannot be sent.
* feat: full-width custom amount and wallet timeout with QR fallback
QR code improvements:
- Add profile picture overlay in center of QR code (25% size, circular)
- Remove redundant "Copy Invoice" button (keep icon button only)
- Show "Open in Wallet" as full-width button
UI improvements:
- Use UserName component everywhere (clickable, styled, shows Grimoire members)
- Custom amount now full-width on separate line
- Better visual hierarchy
Default amounts updated:
- Changed from [21, 100, 500, 1000, 5000, 10000]
- To [21, 420, 2100, 42000]
- More aligned with common zap amounts
The profile picture overlay helps users identify who they're zapping
while maintaining QR code scannability. UserName component provides
consistent styling and clickable profile links.

* Add COUNT command for NIP-45 event counting
Implements the COUNT verb from NIP-45, allowing users to count events
on relays without fetching them. Features:
- New `count` command requiring at least one relay
- Filter-only flags (excludes --limit, --close-on-eose, --view)
- Single relay shows centered count result
- Multiple relays show per-relay breakdown
- Handles approximate counts, errors, and unsupported relays
- Supports $me/$contacts aliases and NIP-05 resolution
Examples:
count relay.damus.io -k 3 -p npub1...
count nos.lol relay.damus.io -k 1 -a fiatjaf.com
* Fix $me and $contacts alias resolution in CountViewer
- Fetch contact list (kind 3) using useNostrEvent hook
- Extract contacts from p tags to resolve $contacts alias
- Add "Account Required" message when aliases used without active account
- Match ReqViewer pattern for consistent alias resolution
* Refactor: extract FilterSummaryBadges for compact headers
- Create shared FilterSummaryBadges component (nostr/FilterSummaryBadges.tsx)
- Simplify CountViewer header to single compact line
- Use FilterSummaryBadges in both ReqViewer and CountViewer
- Remove verbose collapsible filter section from CountViewer
* Remove 'events' suffix from count result
* Update count synopsis to show relays can appear anywhere
* Refactor CountViewer to use applesauce-relay pool
Replace manual WebSocket connections with the relay pool's
count() method for NIP-45 COUNT requests. This provides:
- Proper connection reuse via the existing relay pool
- Automatic reconnection handling
- Better integration with the rest of the app
Remove the approximate property since applesauce-relay's
CountResponse type doesn't expose it yet.
* Simplify CountViewer with one-shot requests and compact UI
- Use per-relay count requests with firstValueFrom and timeout
instead of pool.count() observable that may not complete
- Replace Collapsible-based header with icon-only DropdownMenus
matching ReqViewer's compact style
- Add raw JSON filter view with syntax highlighting and copy button
- Show relay count and filter in dropdowns instead of expanded sections
- Requests complete after timeout (10s) instead of spinning indefinitely
* Add NIP-45 support detection via NIP-11 relay info
- Check relay's supported_nips via NIP-11 before sending COUNT request
- Return early with "unsupported" status if relay explicitly doesn't support NIP-45
- Differentiate UI between unsupported (yellow Ban icon) and error (red AlertCircle)
- Provide clearer error messages based on whether NIP-11 info was available
- Uses cached relay info when available to avoid redundant requests
* Improve CountViewer header with human-readable filter summary
- Show kinds as badges, authors ("by"), mentions ("@"), hashtags on left
- Move relay status into relay dropdown with per-relay results
- Dropdown shows count per relay, status icons, and error tooltips
- Header now shows "2/3" style relay count trigger with loading state
* Reorder CountViewer header controls and remove redundant mention prefix
- Change control order to: refresh, relays, filter (was: filter, relays, refresh)
- Remove redundant "@" prefix from mentions since UserName with isMention already shows @
* Increase COUNT timeout to 30s and improve window title
- Extend per-relay timeout from 10s to 30s for more reliable results
- Update count window title to show human-readable kind names instead of
command-line format (e.g., "count: Short Note by abc123..." instead of
"count -k 1 -a npub...")
* Add spell support for COUNT commands
- Extend spell system to support both REQ and COUNT commands
- Add detectCommandType() to identify command type from string
- Update encodeSpell to use ["cmd", "COUNT"] tag for count commands
- Update decodeSpell to handle COUNT spells
- Update reconstructCommand to accept cmdType parameter
- Add "Save as spell" option to COUNT windows in WindowToolbar
- Update SpellDialog to handle both REQ and COUNT commands
* Add dynamic window title for COUNT with human-readable filter summary
- Add profile fetching for COUNT authors and tagged users
- Add countTitle useMemo with human-readable kind names, authors, mentions, hashtags, and search
- Use same formatting helpers as REQ titles (getKindName, formatProfileNames, etc.)
- Add countTitle to title priority chain after reqTitle
- Title now shows "Short Note • @alice • #bitcoin" instead of "COUNT"
* Update count command documentation for production
- Add note about automatic NIP-11/NIP-45 support detection
- Mention spell saving capability in description
* Add automatic relay selection with NIP-45 filtering for COUNT
- Make relays optional in count-parser (no longer throws if none specified)
- Add useOutboxRelays for automatic relay selection based on filter criteria
- Filter selected relays by NIP-45 support via NIP-11 before querying
- Show "Selecting relays..." and "Filtering by NIP-45..." loading states
- Fall back to aggregator relays if no NIP-45 relays found
- Update man page: relays now optional, new examples showing auto-selection
* Revert automatic relay selection for COUNT command
Simplify COUNT by requiring explicit relay specification:
- Restore relay requirement validation in count-parser.ts
- Remove useOutboxRelays and NIP-45 auto-filtering from CountViewer
- Update man page documentation to reflect required relays
- Keep NIP-45 support detection for better error messages
This keeps the feature simpler for now; automatic relay selection
can be added later when the UX is better understood.
* Reduce padding and sizing in COUNT single result view
