# Tapestry Social Graph Integration

You are building social features for a React Native (Expo) mobile app called **Copium** - a social trading app using Tapestry and Polymarket.

## Project Context

- **Framework**: React Native with Expo Router (file-based routing)
- **Auth**: Privy (OAuth + embedded Solana wallet) + Mobile Wallet Adapter (MWA)
- **Wallet hook**: `useUnifiedWallet()` from `@/hooks/use-wallet` provides `address`, `walletType`, `provider`, `isConnected`, `logout`
- **State**: React Query (`@tanstack/react-query`) for server state
- **Styling**: StyleSheet with `#0a0a0a` bg, `#232323` borders, `PlusJakartaSans` font
- **API Key**: `process.env.TAPESTRY_API_KEY` (server-side only, stored in `.env.local`)
- **Base URL**: `https://api.usetapestry.dev/api/v1`

## API Authentication

All endpoints require `apiKey` as a query parameter:
```
GET /profiles/{id}?apiKey=YOUR_API_KEY
```

The API key is in `.env.local` as `TAPESTRY_API_KEY`. Since this is a React Native app (no server-side routes), call the Tapestry API directly from a utility module, keeping the API key secure via `process.env.TAPESTRY_API_KEY` (bundled at build time but not exposed to web).

## Execution Methods (for write operations)

| Method | Speed | Use When |
|--------|-------|----------|
| `FAST_UNCONFIRMED` | <1s | Default. Returns after graph DB write, on-chain tx in background |
| `QUICK_SIGNATURE` | ~5s | Need tx signature but don't need confirmation |
| `CONFIRMED_AND_PARSED` | ~15s | Need full on-chain confirmation |

## API Client Pattern

Create API calls in `lib/tapestry/` directory. Use this pattern:

```typescript
// lib/tapestry/client.ts
const TAPESTRY_BASE = 'https://api.usetapestry.dev/api/v1';
const API_KEY = process.env.TAPESTRY_API_KEY!;

export async function tapestryFetch<T>(
  endpoint: string,
  options?: { method?: string; body?: any; params?: Record<string, string> }
): Promise<T> {
  const { method = 'GET', body, params = {} } = options ?? {};
  const url = new URL(`${TAPESTRY_BASE}${endpoint}`);
  url.searchParams.set('apiKey', API_KEY);
  Object.entries(params).forEach(([k, v]) => v && url.searchParams.set(k, v));

  const res = await fetch(url.toString(), {
    method,
    headers: body ? { 'Content-Type': 'application/json' } : undefined,
    body: body ? JSON.stringify(body) : undefined,
  });

  if (!res.ok) {
    const err = await res.json().catch(() => ({}));
    throw new Error(err.error || `Tapestry API error: ${res.status}`);
  }
  return res.json();
}
```

## React Hook Pattern

```typescript
// hooks/use-tapestry-profile.ts
import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
import { tapestryFetch } from '@/lib/tapestry/client';

export function useTapestryProfile(username: string) {
  return useQuery({
    queryKey: ['tapestry-profile', username],
    queryFn: () => tapestryFetch<ProfileResponse>(`/profiles/${username}`),
    enabled: !!username,
  });
}
```

## Key Integration Points for Copium

### 1. Profile Creation (on signup/login)
After wallet connection + X login, call `findOrCreate`:
```typescript
await tapestryFetch('/profiles/findOrCreate', {
  method: 'POST',
  body: {
    username: twitterHandle, // from Privy OAuth
    walletAddress: address,  // from useUnifiedWallet
    blockchain: 'SOLANA',
    image: twitterProfileImage,
    bio: twitterBio,
    contact: { id: twitterHandle, type: 'TWITTER' },
  },
});
```

### 2. Follow/Unfollow
```typescript
await tapestryFetch('/followers/add', {
  method: 'POST',
  body: { startId: myProfileId, endId: targetProfileId },
});
```

### 3. Create a Post (Content)
```typescript
await tapestryFetch('/contents/findOrCreate', {
  method: 'POST',
  body: {
    id: `post-${Date.now()}`,
    profileId: myProfileId,
    properties: [
      { key: 'text', value: 'My post content' },
      { key: 'type', value: 'trade_call' },
    ],
  },
});
```

### 4. Like Content
```typescript
await tapestryFetch(`/likes/${contentId}`, {
  method: 'POST',
  body: { startId: myProfileId },
});
```

### 5. Comment on Content
```typescript
await tapestryFetch('/comments/', {
  method: 'POST',
  body: {
    profileId: myProfileId,
    contentId: contentId,
    text: 'Great trade!',
  },
});
```

### 6. Activity Feed
```typescript
const feed = await tapestryFetch('/activity/feed', {
  params: { username: myUsername },
});
```

### 7. Search Users
```typescript
const results = await tapestryFetch('/search/profiles', {
  params: { query: searchText },
});
```

### 8. Polymarket Integration Pattern
Store Polymarket-related data as content properties:
```typescript
await tapestryFetch('/contents/findOrCreate', {
  method: 'POST',
  body: {
    id: `prediction-${marketId}-${profileId}`,
    profileId: myProfileId,
    properties: [
      { key: 'type', value: 'prediction' },
      { key: 'marketId', value: polymarketConditionId },
      { key: 'position', value: 'YES' },
      { key: 'amount', value: 50 },
      { key: 'odds', value: 0.65 },
    ],
  },
});
```

## Response Types

```typescript
interface TapestryProfile {
  id: string;
  namespace: string;
  created_at: number;
  username: string;

}

interface PaginatedResponse<T> {
