🏗️ Architecture

Domain Models (CommonModel.scala)

• TradingOffer - Buy/sell offers with expiry and minimum fill
• MarketOrder - Market orders with side (BUY/SELL)
• MarketMatch - Order matching records
• MarketTrade - Executed trades
• Settlement - Multi-step settlement process
• Deposit - Blockchain deposit tracking
• Withdrawal - Blockchain withdrawal tracking
• PaymentAuth - TCC payment authorization

JSON Models (JSONFactory7.0.0.scala)

• Request models for all create/update operations
• Response models with snake_case field names
• Conversion functions from domain to JSON

Connector Layer (Connector.scala + LocalMappedConnector.scala)

• 20+ new connector methods
• Thread-safe in-memory storage (ConcurrentHashMap)
• Full CRUD operations for all models

HTTP Layer (Http4s700.scala)

• 17 new HTTP endpoints
• Full OBP convention compliance
• Comprehensive ResourceDocs
• Error handling with proper HTTP codes

Business Logic (NewStyle.scala)

• 20+ wrapper methods
• CallContext propagation
• Error handling with Box[T]

🔑 Key Features

1. OBP Convention Compliance ✅

All endpoints follow the standard OBP path pattern:

/obp/v7.0.0/banks/{BANK_ID}/accounts/{ACCOUNT_ID}/views/{VIEW_ID}/{resource}

2. TCC Payment Pattern ✅

Try-Confirm-Cancel pattern for atomic payments:

PREAUTH (freeze funds) → CAPTURED (deduct) or RELEASED (rollback)

3. Blockchain Integration ✅

• Track confirmations in real-time
• Support multiple blockchain networks
• Automatic status updates
• Error tracking

4. Audit Trail ✅

• Every operation tracked with userId
• Optional consentId for compliance
• Timestamps (createdAt, updatedAt)

5. Thread Safety ✅

• All storage uses ConcurrentHashMap
• No race conditions
• Safe for concurrent requests
