From c832b58fd9b4bb501b1dcc8d3dfe5edd824da61f Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 15 Jan 2026 12:26:58 +0000 Subject: [PATCH] Add NIP-60 Cashu wallet viewer command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented a new `wallet` command to view and display NIP-60 Cashu wallets stored on Nostr relays. ## Changes ### New Command: wallet - Added `wallet [identifier]` command to man pages (src/types/man.ts) - Supports viewing own wallet (`wallet` or `wallet $me`) - Supports viewing other users' wallets (`wallet npub1...`, `wallet fiatjaf.com`) - Added wallet app ID to AppId type (src/types/app.ts) ### WalletViewer Component (src/components/WalletViewer.tsx) Created comprehensive NIP-60 wallet viewer with: **Data Fetching:** - Fetches kind:17375 (wallet config) using eventStore.replaceable() - Fetches kind:7375 (token events) using eventStore.timeline() - Fetches kind:7376 (history events) using eventStore.timeline() - Reactive updates using applesauce-react hooks (use$) **UI Features:** - Wallet status display (config, tokens, history counts) - Balance card (shows encrypted state, token count) - Transaction history card (shows encrypted state) - Developer info section with raw event JSON - Educational content about NIP-60 and Cashu - Links to compatible apps (noStrudel, Cashu.me) - "What is NIP-60?" help section **States Handled:** - No active account (requires login) - No wallet found (educational content for own wallet) - Wallet found but encrypted (displays structure) - Own wallet vs other user's wallet **Security:** - Shows wallet data is NIP-44 encrypted - Indicates decryption functionality is planned for future - Prevents viewing other users' encrypted wallet data - Educational content about privacy model ### WindowRenderer Integration - Added lazy import for WalletViewer component - Added case for "wallet" appId in switch statement - Passes pubkey prop to WalletViewer ## User Experience The wallet command provides: ✅ Clear indication of wallet existence ✅ Visual feedback on encrypted state ✅ Event counts for transparency ✅ Educational content for new users ✅ Developer-friendly raw event inspection ✅ Links to specification and compatible apps ## Future Enhancements This implementation provides the foundation for: - NIP-44 decryption with user's private key - Balance calculation from decrypted proofs - Transaction history display - Wallet management operations (pending applesauce-wallet API) ## Testing The component: - Handles missing account gracefully - Displays appropriate messaging for different states - Uses proper TypeScript types - Follows codebase patterns (ProfileViewer, BlossomViewer) - No TypeScript compilation errors ## Documentation Referenced - NIP-60 specification: github.com/nostr-protocol/nips/blob/master/60.md - .claude/skills/nostr/references/nip-60-cashu-wallet.md - applesauce documentation: hzrd149.github.io/applesauce/ --- src/components/WalletViewer.tsx | 440 ++++++++++++++++++++++++++++++ src/components/WindowRenderer.tsx | 6 + src/types/app.ts | 1 + src/types/man.ts | 41 +++ 4 files changed, 488 insertions(+) create mode 100644 src/components/WalletViewer.tsx diff --git a/src/components/WalletViewer.tsx b/src/components/WalletViewer.tsx new file mode 100644 index 0000000..b17ecf3 --- /dev/null +++ b/src/components/WalletViewer.tsx @@ -0,0 +1,440 @@ +import { useEventStore, use$ } from "applesauce-react/hooks"; +import { useGrimoire } from "@/core/state"; +import { + Wallet, + Lock, + Download, + AlertCircle, + Coins, + History, +} from "lucide-react"; +import { Button } from "@/components/ui/button"; +import { + Card, + CardContent, + CardDescription, + CardHeader, + CardTitle, +} from "@/components/ui/card"; +import { Alert, AlertDescription } from "@/components/ui/alert"; +import { useMemo, useState } from "react"; +import type { NostrEvent } from "nostr-tools"; + +export interface WalletViewerProps { + pubkey: string; +} + +/** + * WalletViewer - NIP-60 Cashu Wallet Display + * Shows wallet configuration, balance, and transaction history + * + * NIP-60 Event Kinds: + * - kind:17375 - Wallet config (replaceable, encrypted) + * - kind:7375 - Unspent tokens (multiple allowed, encrypted) + * - kind:7376 - Transaction history (optional, encrypted) + */ +export function WalletViewer({ pubkey }: WalletViewerProps) { + const { state } = useGrimoire(); + const eventStore = useEventStore(); + const [unlocked, setUnlocked] = useState(false); + + // Resolve $me alias + const resolvedPubkey = + pubkey === "$me" ?
