                                    → Worker Nodes (Trading Engines)

Phase 1: Multi-Tenancy Foundation (Weeks 1-4)

1.1 Database Migration

Current: SQLite (single user) Target: PostgreSQL with tenant isolation

-- New schema structure
CREATE TABLE tenants (
  id UUID PRIMARY KEY,
  name VARCHAR(255),
  plan_tier VARCHAR(50), -- starter, pro, enterprise
  api_key_hash VARCHAR(255),
  created_at TIMESTAMP,
  status VARCHAR(50) -- active, suspended, trial
);

CREATE TABLE tenant_configs (
  tenant_id UUID REFERENCES tenants(id),
  weex_api_key_encrypted TEXT,
  ai_provider VARCHAR(50),
  ai_api_key_encrypted TEXT,
  risk_settings JSONB,
  analyst_configs JSONB
);

CREATE TABLE tenant_trades (
  id UUID PRIMARY KEY,
  tenant_id UUID REFERENCES tenants(id),
  symbol VARCHAR(50),
  action VARCHAR(20),
  -- ... existing trade fields
  INDEX idx_tenant_trades (tenant_id, created_at)
);

-- Row-Level Security (RLS)
ALTER TABLE tenant_trades ENABLE ROW LEVEL SECURITY;
CREATE POLICY tenant_isolation ON tenant_trades
  USING (tenant_id = current_setting('app.current_tenant')::UUID);

1.2 Authentication & Authorization

Stack: JWT + API Keys + OAuth (optional)

// src/services/auth/TenantAuthService.ts
interface TenantAuth {
  tenantId: string;
  userId: string;
  role: "owner" | "admin" | "viewer";
  permissions: string[];
}

class TenantAuthService {
  async authenticate(apiKey: string): Promise<TenantAuth>;
  async validateAccess(tenantId: string, userId: string): Promise<boolean>;
  async rotateApiKey(tenantId: string): Promise<string>;
}

1.3 Tenant Isolation Middleware

// src/api/middleware/tenantContext.ts
export const tenantContext = async (req, res, next) => {
  const apiKey = req.headers["x-api-key"];
  const tenant = await TenantAuthService.authenticate(apiKey);

  // Set tenant context for all DB queries
  await db.query("SET app.current_tenant = $1", [tenant.tenantId]);
  req.tenant = tenant;
  next();
};

// Apply to all routes
app.use("/api/*", tenantContext);

1.4 Secrets Management

Current: .env file Target: Encrypted per-tenant secrets

// src/services/secrets/SecretManager.ts
class SecretManager {
  private kms: AWS.KMS | GoogleKMS; // or Vault

  async encryptSecret(tenantId: string, key: string, value: string);
  async decryptSecret(tenantId: string, key: string): Promise<string>;
  async rotateKeys(tenantId: string);
}

Phase 2: Web Intelligence Infrastructure (Weeks 5-8)

2.1 Shared Browser Pool Architecture

Challenge: Each tenant needs web scraping, but browsers are resource-heavy. Solution: Shared browser pool with tenant isolation.

// src/services/intelligence/BrowserPoolService.ts
class BrowserPoolService {
  private pool: BrowserPool;
  private queue: Bull.Queue;

  constructor() {
    this.pool = new BrowserPool({
      maxConcurrent: 20, // Scale based on plan tier
      timeout: 30000,
      retries: 3,
    });

    this.queue = new Bull("scraping-jobs", {
      redis: { host: "redis", port: 6379 },
    });
  }

  async scrape(tenantId: string, job: ScrapingJob): Promise<ScrapedData> {
    // Rate limiting per tenant
    const limit = await this.getRateLimit(tenantId);
    if (!(await this.checkLimit(tenantId, limit))) {
      throw new RateLimitError();
    }

    // Queue job with priority based on plan tier
    const priority = this.getPriority(tenantId);
    return this.queue.add(job, { priority });
  }

  private getPriority(tenantId: string): number {
    const tier = await this.getTenantTier(tenantId);
    return {
      starter: 3,
      pro: 2,
      enterprise: 1,
    }[tier];
  }
}

2.2 Intelligence Services (Multi-Tenant)

// src/services/intelligence/NewsIntelligenceService.ts
class NewsIntelligenceService {
  async gatherNews(tenantId: string, symbols: string[]): Promise<NewsData> {
    // Check tenant's plan limits
    const plan = await this.getTenantPlan(tenantId);
    const sources = this.getSourcesForPlan(plan);

    // Shared cache with tenant prefix
    const cacheKey = `news:${tenantId}:${symbols.join(",")}`;
    const cached = await redis.get(cacheKey);
    if (cached) return JSON.parse(cached);

    // Scrape from allowed sources
    const results = await Promise.all(
      sources.map((source) => this.scrapeSource(source, symbols)),
    );

    await redis.setex(cacheKey, 1800, JSON.stringify(results));
    return results;
  }

  private getSourcesForPlan(plan: string): string[] {
    return {
      starter: ["coindesk", "reddit"],
      pro: ["coindesk", "reddit", "twitter", "cointelegraph"],
      enterprise: ["all"], // + premium sources
    }[plan];
  }
}

2.3 Playwright Integration (Shared Infrastructure)

// src/services/intelligence/scrapers/TwitterScraper.ts
class TwitterScraper {
  private browserPool: BrowserPoolService;

  async getTrendingCrypto(tenantId: string): Promise<TrendingData> {
    const browser = await this.browserPool.acquire(tenantId);

    try {
      const page = await browser.newPage();

      // Stealth mode
      await page.setExtraHTTPHeaders({
        "User-Agent": this.getRandomUserAgent(),
      });

      await page.goto("https://twitter.com/search?q=%23bitcoin&f=live");

      const trends = await page.$$eval(".trend-item", (items) =>
        items.map((item) => ({
          text: item.textContent,
          volume: item.dataset.volume,
        })),
      );

      return this.analyzeTrends(trends);
    } finally {
      await this.browserPool.release(browser);
    }
  }
}

// Similar scrapers for:
// - RedditScraper.ts
// - CoinDeskScraper.ts
// - OnChainScraper.ts (Etherscan, etc.)
// - TelegramScraper.ts
// - DiscordScraper.ts

2.4 Rate Limiting & Fair Usage

// src/services/intelligence/RateLimiter.ts
class IntelligenceRateLimiter {
  private redis: Redis;

  async checkLimit(tenantId: string, resource: string): Promise<boolean> {
    const plan = await this.getTenantPlan(tenantId);
    const limits = this.getLimitsForPlan(plan);

    const key = `ratelimit:${tenantId}:${resource}`;
    const current = await this.redis.incr(key);

    if (current === 1) {
      await this.redis.expire(key, 3600); // 1 hour window
    }

    return current <= limits[resource];
  }

  private getLimitsForPlan(plan: string) {
    return {
      starter: {
        news_scrapes: 100,
        social_scrapes: 50,
        onchain_queries: 20,
      },
      pro: {
        news_scrapes: 500,
        social_scrapes: 300,
        onchain_queries: 100,
      },
      enterprise: {
        news_scrapes: -1, // unlimited
        social_scrapes: -1,
        onchain_queries: -1,
      },
    }[plan];
  }
}

Phase 3: Trading Engine Isolation (Weeks 9-10)

3.1 Worker-Based Architecture

Problem: Can't run all tenants in one process Solution: Separate worker processes per tenant

// src/workers/TradingWorkerManager.ts
class TradingWorkerManager {
  private workers: Map<string, Worker> = new Map();
  private queue: Bull.Queue;

  async startTenantEngine(tenantId: string) {
    // Check if already running
    if (this.workers.has(tenantId)) {
      throw new Error("Engine already running");
    }

    // Spawn isolated worker
    const worker = new Worker("./TradingWorker.js", {
      workerData: { tenantId },
    });

    worker.on("message", (msg) => this.handleWorkerMessage(tenantId, msg));
    worker.on("error", (err) => this.handleWorkerError(tenantId, err));

    this.workers.set(tenantId, worker);

    // Store state in Redis
    await redis.hset(`worker:${tenantId}`, {
      status: "running",
      startedAt: Date.now(),
      pid: worker.threadId,
    });
  }

  async stopTenantEngine(tenantId: string) {
    const worker = this.workers.get(tenantId);
    if (worker) {
      worker.terminate();
      this.workers.delete(tenantId);
      await redis.hdel(`worker:${tenantId}`);
    }
  }
}

3.2 Isolated Trading Worker

// src/workers/TradingWorker.ts
import { parentPort, workerData } from "worker_threads";

const { tenantId } = workerData;

class IsolatedTradingEngine {
  private tenantId: string;
  private config: TenantConfig;
  private engine: AutonomousTradingEngine;

  async initialize() {
    // Load tenant config
    this.config = await this.loadTenantConfig(this.tenantId);

    // Initialize engine with tenant-specific settings
    this.engine = new AutonomousTradingEngine({
      tenantId: this.tenantId,
      weexCredentials: await this.decryptCredentials(),
      aiProvider: this.config.aiProvider,
      riskSettings: this.config.riskSettings,
    });

    // Start trading loop
    await this.engine.start();
  }

  async run() {
    while (true) {
      try {
        await this.engine.runCycle();

        // Report status to parent
        parentPort?.postMessage({
          type: "status",
          data: await this.engine.getStatus(),
        });

        await this.sleep(this.config.cycleInterval);
      } catch (error) {
        parentPort?.postMessage({
          type: "error",
          error: error.message,
        });
      }
    }
  }
}

const engine = new IsolatedTradingEngine();
engine.initialize().then(() => engine.run());

3.3 Resource Allocation by Plan Tier

// src/services/resource/ResourceAllocator.ts
class ResourceAllocator {
  getAllocation(plan: string): ResourceAllocation {
    return {
      starter: {
        maxConcurrentPositions: 3,
        maxDailyTrades: 20,
        cycleInterval: 300000, // 5 min
        aiCallsPerHour: 60,
        browserScrapesPerHour: 100,
        cpuPriority: "low",
        memoryLimit: "512MB",
      },
      pro: {
        maxConcurrentPositions: 10,
        maxDailyTrades: 100,
        cycleInterval: 60000, // 1 min
        aiCallsPerHour: 300,
        browserScrapesPerHour: 500,
        cpuPriority: "normal",
        memoryLimit: "2GB",
      },
      enterprise: {
        maxConcurrentPositions: 50,
        maxDailyTrades: -1, // unlimited
        cycleInterval: 30000, // 30 sec
        aiCallsPerHour: -1,
        browserScrapesPerHour: -1,
        cpuPriority: "high",
        memoryLimit: "8GB",
        dedicatedWorker: true,
      },
    }[plan];
  }
}

6.4 Cost Optimization

// src/services/optimization/CostOptimizer.ts
class CostOptimizer {
  // Intelligent caching to reduce AI costs
  async optimizeAICalls(tenantId: string) {
    // Use cheaper models for low-confidence scenarios
    const tier = await this.getTenantTier(tenantId);

    return {
      starter: {
        analyst: "gemini-1.5-flash", // Cheaper
        judge: "gemini-1.5-flash",
      },
      pro: {
        analyst: "gemini-1.5-pro",
        judge: "gemini-1.5-pro",
      },
      enterprise: {
        analyst: "gemini-1.5-pro",
        judge: "claude-3-opus", // Best quality
      },
    }[tier];
  }

  // Batch scraping jobs to reduce browser overhead
  async batchScrapingJobs(jobs: ScrapingJob[]) {
    // Group by domain to reuse browser contexts
    const grouped = this.groupByDomain(jobs);

    return Promise.all(
      grouped.map((group) => this.scrapeInSingleContext(group)),
    );
  }
}

Phase 7: Advanced Features (Post-MVP)

7.1 Custom Analyst Builder

Allow users to create their own AI analysts:

// Dashboard: /analysts/create
interface CustomAnalyst {
  name: string;
  personality: string;
  strategy: {
    type: "trend-following" | "mean-reversion" | "arbitrage" | "custom";
    indicators: string[];
    rules: TradingRule[];
  };
  riskProfile: "conservative" | "moderate" | "aggressive";
  systemPrompt: string; // Advanced users can write custom prompts
}

7.2 Backtesting Engine

// src/services/backtest/BacktestService.ts
class BacktestService {
  async runBacktest(tenantId: string, config: BacktestConfig) {
    const historicalData = await this.fetchHistoricalData(
      config.symbols,
      config.startDate,
      config.endDate,
    );

    // Simulate trading with historical data
    const results = await this.simulate(
      config.analystConfigs,
      historicalData,
      config.riskSettings,
    );

    return {
      totalReturn: results.totalReturn,
      sharpeRatio: results.sharpeRatio,
      maxDrawdown: results.maxDrawdown,
      winRate: results.winRate,
      trades: results.trades,
    };
  }
}

7.3 Social Trading / Copy Trading

// Allow users to follow top-performing tenants
interface CopyTradingService {
  async followTrader(followerId: string, leaderId: string, allocation: number)
  async copyTrade(leaderId: string, trade: Trade)
  async getLeaderboard(): Promise<TopTrader[]>
}

7.4 White-Label Solution

Enterprise tier can white-label the platform:

interface WhiteLabelConfig {
  domain: string;
  branding: {
    logo: string;
    colors: ColorScheme;
    companyName: string;
  };
  features: {
    hidePoweredBy: boolean;
    customAnalysts: boolean;
    apiAccess: boolean;
  };
}
