+## @opchan/react
+
+Lightweight React provider and hooks for building OpChan clients on top of `@opchan/core`.
+
+### Install
+
+```bash
+npm i @opchan/react @opchan/core react react-dom
+```
+
+### Quickstart
+
+```tsx
+import React from 'react';
+import { createRoot } from 'react-dom/client';
+import { OpChanProvider } from '@opchan/react';
+
+const config = {
+  // See @opchan/core for full options
+  waku: { bootstrapPeers: [], pubsubTopic: 'opchan-v1' },
+  database: { name: 'opchan' },
+};
+
+// Optional: bridge your wallet to OpChan
+const walletAdapter = {
+  getAccount() {
+    // Return { address, walletType: 'bitcoin' | 'ethereum' } or null
+    return null;
+  },
+  onChange(cb) {
+    // Subscribe to wallet changes; return an unsubscribe function
+    return () => {};
+  },
+};
+
+function App() {
+  return (
+    <OpChanProvider config={config} walletAdapter={walletAdapter}>
+      {/* your app */}
+    </OpChanProvider>
+  );
+}
+
+createRoot(document.getElementById('root')!).render(<App />);
+```
+
+### Common usage
+
+```tsx
+import { useForum } from '@opchan/react';
+
+export function NewPostButton({ cellId }: { cellId: string }) {
+  const { user, content, permissions } = useForum();
+
+  const onCreate = async () => {
+    if (!permissions.canPost) return;
+    await content.createPost({ cellId, title: 'Hello', content: 'World' });
+  };
+
+  return (
+    <button disabled={!permissions.canPost || !user.isAuthenticated} onClick={onCreate}>
+      New post
+    </button>
+  );
+}
+```
+
+```tsx
+import { useAuth, useUserDisplay } from '@opchan/react';
+
+export function Connect() {
+  const { currentUser, connect, disconnect, verifyOwnership } = useAuth();
+  const display = useUserDisplay(currentUser?.address ?? '');
+
+  return (
+    <div>
+      {currentUser ? (
+        <>
+          <span>{display.displayName}</span>
+          <button onClick={() => verifyOwnership()}>Verify</button>
+          <button onClick={() => disconnect()}>Disconnect</button>
+        </>
+      ) : (
+        <button
+          onClick={() =>
+            connect({ address: '0xabc...1234', walletType: 'ethereum' })
+          }
+        >
+          Connect
+        </button>
+      )}
+    </div>
+  );
+}
+```
+
+### API
+
+- **Providers**
+  - **`OpChanProvider`**: High-level provider that constructs an `OpChanClient` and wires persistence/events.
+    - Props:
+      - `config: OpChanClientConfig` — core client configuration.
+      - `walletAdapter?: WalletAdapter` — optional bridge to your wallet system.
+      - `children: React.ReactNode`.
+    - Types:
+      - `WalletAdapterAccount`: `{ address: string; walletType: 'bitcoin' | 'ethereum' }`.
+      - `WalletAdapter`:
+        - `getAccount(): WalletAdapterAccount | null`
+        - `onChange(cb: (a: WalletAdapterAccount | null) => void): () => void`
+  - **`ClientProvider`**: Low-level provider if you construct `OpChanClient` yourself.
+    - Props: `{ client: OpChanClient; children: React.ReactNode }`.
+
+- **Hooks**
+  - **`useForum()`** → `{ user, content, permissions, network }` — convenience bundle of the hooks below.
+
+  - **`useAuth()`** → session & identity actions
+    - Data: `currentUser`, `verificationStatus`, `isAuthenticated`, `delegationInfo`.
+    - Actions: `connect({ address, walletType })`, `disconnect()`, `verifyOwnership()`,
+      `delegate(duration)`, `delegationStatus()`, `clearDelegation()`,
+      `updateProfile({ callSign?, displayPreference? })`.
+
+  - **`useContent()`** → forum data & actions
+    - Data: `cells`, `posts`, `comments`, `bookmarks`, `postsByCell`, `commentsByPost`,
+      `cellsWithStats`, `userVerificationStatus`, `lastSync`, `pending` helpers.
+    - Actions: `createCell({ name, description, icon? })`,
+      `createPost({ cellId, title, content })`,
+      `createComment({ postId, content })`,
+      `vote({ targetId, isUpvote })`,
+      `moderate.{post,unpost,comment,uncomment,user,unuser}(...)`,
+      `togglePostBookmark(post, cellId?)`, `toggleCommentBookmark(comment, postId?)`,
+      `removeBookmark(bookmarkId)`, `clearAllBookmarks()`, `refresh()`.
+
+  - **`usePermissions()`** → permission checks
+    - Booleans: `canPost`, `canComment`, `canVote`, `canCreateCell`, `canDelegate`.
+    - Functions: `canModerate(cellId)`, `check(action, cellId?) → { allowed, reason }`, `reasons`.
+
+  - **`useNetwork()`** → connection state
+    - Data: `isConnected`, `statusMessage`, `issues`, `canRefresh`.
+    - Actions: `refresh()` — triggers a light data refresh via core.
+
+  - **`useUIState(key, defaultValue, category?)`** → persisted UI state
+    - Returns `[value, setValue, { loading, error? }]`.
+    - Categories: `'wizardStates' | 'preferences' | 'temporaryStates'` (default `'preferences'`).
+
+  - **`useUserDisplay(address)`** → identity details for any address
+    - Returns `{ address, displayName, callSign?, ensName?, ordinalDetails?, verificationStatus, displayPreference, lastUpdated, isLoading, error }`.
+    - Backed by a centralized identity cache; updates propagate automatically.
+
+  - **`useClient()`** → access the underlying `OpChanClient` (advanced use only).
+
+### Notes
+
+- Identity resolution, verification states, and display preferences are centralized and cached;
+  `useUserDisplay` and `useAuth.verifyOwnership()` will keep store and local DB in sync.
+- This package is UI-agnostic; pair with your component library of choice.
