[AndreaDiazCorreia]

Description

Implement functionality to list and filter orders from Mostro relays according to the protocol specification. This includes handling event subscriptions and implementing filtering capabilities.

Implementation Requirements

1. Implement list orders functionality:

interface OrderFilters {
  kinds?: OrderType[];
  status?: OrderStatus;
  fiatCode?: string;
  minAmount?: number;
  maxAmount?: number;
  paymentMethods?: string[];
}

async function listOrders(filters?: OrderFilters): Promise<Order[]> {
  // Subscribe to order events
  // Apply filters
  // Handle event processing
  // Return filtered orders
}

2. Implementation of event subscription:

private subscribeToOrders(): void {
  // Subscribe to kind 38383 events
  // Handle event processing
  // Emit order updates
}

Testing Requirements

describe('listOrders', () => {
  it('should retrieve all pending orders');
  it('should filter by order type');
  it('should filter by fiat currency');
  it('should filter by amount range');
  it('should handle payment method filtering');
  it('should properly update on new orders');
});

Acceptance Criteria

• Order listing implemented
• All filter types supported
• Real-time updates working
• Proper error handling
• Event subscription management
