# OpenRouter-Inspired Marketplace Implementation Status

## Project Overview

This document provides a comprehensive status update on implementing OpenRouter-inspired marketplace enhancements for the ThreeFold marketplace. The goal is to add streamlined "buy now" capabilities and improved wallet management while preserving all existing cart-based functionality.

## Target Features

### 1. Instant Purchase System
- **Goal**: Add "Buy Now" buttons alongside existing "Add to Cart" buttons
- **Requirements**: One-click purchasing that bypasses cart for immediate transactions
- **Integration**: Must work with existing session management and wallet system

### 2. Enhanced Wallet Management
- **Goal**: Easy TFP wallet funding with direct USD input
- **Requirements**: 
  - Quick top-up functionality with preset amounts ($10, $25, $50, $100)
  - User-configurable currency preferences (USD, TFP, CAD, EUR)
  - USD as default display currency
  - Real-time wallet balance in navbar

### 3. OpenRouter-Style Navigation
- **Goal**: Replace simple "Hello, USERNAME" with feature-rich dropdown
- **Requirements**:
  - Wallet balance display in navbar
  - Quick access to wallet management
  - Settings and logout options

### 4. Currency System Enhancement
- **Goal**: Support multiple display currencies while keeping TFP as base
- **Requirements**:
  - Real-time currency conversion
  - User preference storage
  - Marketplace price display in preferred currency

## Implementation Status

### ✅ Completed Components

#### Core Services
- **NavbarService**: Dropdown menu data management using builder pattern
- **InstantPurchaseService**: Buy-now functionality with existing service patterns
- **CurrencyService Extensions**: User preference handling and TFP display support
- **UserPersistence Extensions**: Added `display_currency` and `quick_topup_amounts` fields

#### API Endpoints
- `POST /api/wallet/instant_purchase` - Process immediate purchases
- `POST /api/wallet/quick_topup` - Handle preset amount top-ups
- `GET /api/navbar/dropdown-data` - Fetch dropdown menu data
- `POST /api/user/currency` - Save currency preferences

#### Frontend Enhancements
- **base.html**: OpenRouter-style navbar dropdown with wallet integration
- **wallet/index.html**: Enhanced with quick top-up UI and currency selection
- **marketplace templates**: Buy-now buttons alongside cart functionality
- **settings.html**: Currency preferences tab with form handling

#### Data Model Extensions
```rust
// UserPersistentData additions
pub struct UserPersistentData {
    // ... existing fields
    pub display_currency: Option<String>,
    pub quick_topup_amounts: Option<Vec<Decimal>>,
}

// Order system enhancements
pub enum PurchaseType {
    Cart,
    Instant,
}
```

### ✅ Fixed Issues

#### 1. Navbar Wallet Links
- **Issue**: Links went to non-existent `/wallet` routes
- **Fix**: Updated to correct `/dashboard/wallet` routes in base.html

#### 2. Buy Now Button JavaScript
- **Issue**: Buttons did nothing due to incorrect API endpoint
- **Fix**: Corrected endpoint path and redirect URLs in base.html

#### 3. Marketplace Currency Display
- **Issue**: compute_resources method wasn't using currency conversion
- **Fix**: Updated to use proper `create_price` conversion like other marketplace sections

### 🔧 Current Issues

#### 1. Template Rendering Error
```
[2025-07-31T03:08:28Z ERROR threefold_marketplace::utils] Template rendering error: Failed to render 'dashboard/settings.html'
```
- **Cause**: Likely missing template variables or syntax errors in settings.html
- **Impact**: Settings page not accessible
- **Priority**: High - blocks currency preference functionality

#### 2. Buy TFP Redirect Issue
- **Issue**: "Buy TFP" still redirects to TFP pool page instead of opening popup
- **Expected**: Should open modal popup in wallet page
- **Current**: Redirects to `/dashboard/pools`
- **Priority**: Medium - affects user experience

### 🏗️ Architecture Decisions

#### Currency System
- **Base Currency**: TFP remains fundamental for all calculations
- **Display Currency**: User-configurable preference for UI display
- **Conversion Logic**: Real-time conversion between TFP and display currencies
- **Default**: USD as default display currency

#### Service Layer Pattern
All new services follow existing builder pattern:
```rust
let service = ServiceName::builder()
    .with_option(value)
    .build()?;
```

#### Backward Compatibility
- All existing cart functionality preserved
- Existing API endpoints unchanged
- Database schema extensions only (no breaking changes)
- Template inheritance maintained

## Next Steps

### Immediate Priorities

1. **Fix Template Rendering Error**
   - Debug settings.html template syntax
   - Ensure all required template variables are provided
   - Test template compilation

2. **Fix Buy TFP Redirect**
   - Investigate where Buy TFP button is defined
   - Ensure it opens modal instead of redirecting
   - Test popup functionality

3. **Integration Testing**
   - Test all marketplace sections with currency conversion
   - Verify buy-now functionality across different product types
   - Test currency preference saving and loading

### Testing Checklist

- [ ] Settings page loads without template errors
- [ ] Currency preferences can be saved and loaded
- [ ] Buy TFP opens popup modal in wallet page
- [ ] Buy now buttons work in all marketplace sections
- [ ] Navbar wallet links go to correct routes
- [ ] Currency conversion works in all marketplace sections
- [ ] Wallet balance displays correctly in navbar

## Conclusion

The OpenRouter-inspired enhancements are approximately 95% complete. The core functionality is implemented and most issues are resolved. The remaining template rendering error and Buy TFP redirect issue need to be addressed to complete the implementation.

The architecture maintains consistency with existing patterns while adding modern e-commerce capabilities. Once the remaining issues are resolved, the marketplace will provide a significantly enhanced user experience with streamlined purchasing and flexible currency management.
