Multi-Tenant Architecture

The platform supports multiple tenants with isolated data and customizable features:

Tenant-specific database isolation
Custom branding and theming
Configurable features and modules
Independent KYC provider settings
Custom domain support

Multi-Tenant Architecture Deep Dive

Overview

MB Community Deals implements a sophisticated multi-tenant architecture that enables white-label deployments while maintaining complete data isolation, security, and customization capabilities. Each tenant operates as an independent platform instance with its own users, deals, configurations, and branding.

Tenant Isolation Model

1. Data Isolation Strategy

Row-Level Security (RLS)

Every database table includes a tenant_id column
PostgreSQL Row-Level Security policies enforce isolation
Automatic tenant context injection in all queries
Cross-tenant data access is impossible at the database level

┌─────────────────────────────────────────────────────────┐
│                    Application Layer                     │
├─────────────────────────────────────────────────────────┤

│                  Tenant-Aware ORM Layer                  │
│            (Automatically filters by tenant_id)          │
├─────────────────────────────────────────────────────────┤
│                    PostgreSQL Database                   │
│         (Row-Level Security + tenant_id column)         │
└─────────────────────────────────────────────────────────┘

2. Tenant Identification Methods

Domain-Based Routing

Primary domain: tenant1.mbcommunitydeals.com
Custom domain: invest.clientcompany.com
Domain alias support for multiple URLs per tenant

Tenant Resolution Flow

Request arrives at platform
Domain/subdomain extracted from request
Tenant lookup in tenants and domain_aliases tables
Tenant context established for entire request lifecycle
All subsequent queries filtered by tenant_id

Technical Implementation Details

1. Middleware Architecture

Tenant Context Middleware

// Establishes tenant context for every request
export async function tenantMiddleware(request: Request) {
  const hostname = request.headers.get('host');
  const tenant = await resolveTenant(hostname);
  
  if (!tenant) {
    return new Response('Tenant not found', { status: 404 });
  }
  
  // Inject tenant context
  request.tenantId = tenant.id;
  request.tenantConfig = tenant.settings;
  
  return NextResponse.next();
}

2. Database Query Interception

Automatic Tenant Filtering

// All queries automatically filtered by tenant
export class TenantAwareRepository {
  async find(conditions: any) {
    const tenantId = getCurrentTenantId();
    return await pool.query(
      'SELECT * FROM table WHERE tenant_id = $1 AND ...',
      [tenantId, ...params]
    );
  }
}

3. Smart Contract Multi-Tenancy

Contract Deployment Strategy

Shared Contracts: Platform-wide contracts (service fees)
Tenant Contracts: Isolated per tenant (token sales, pools)
Factory Pattern: Dynamic contract creation per deal

Platform Service Contract (Shared)
    ├── Tenant A Factory
    │   ├── Deal 1 TokenSale
    │   ├── Deal 2 TokenSale
    │   └── Escrow Contracts
    └── Tenant B Factory
        ├── Deal 1 TokenSale
        ├── Deal 2 TokenSale
        └── Escrow Contracts

Tenant Data Management
