Development of a self-hosted SaaS module (MVP)
Goal: create a self-hosted SaaS system for transferring leads from lead forms (FB / TikTok / Google) to the broker's CRM, with emulation of auto-login, fingerprint, contact validation, and billing in USDT.
⸻
🎯 About the project
Product: a universal bridge between lead forms (FB / TikTok / Google) and brokerage CRMs.
Niche: Crypto / Forex / Betting / Nutra
Target Audience: media buyers and affiliate teams that drive traffic to gray verticals.
Type of work: fixed payment for MVP + possible long-term cooperation for support and new modules.

• Output of the list of recent leads
• Ability to view delivery status
📤 2. White-page support
• Scenario: FB Ads → White Page → Button → FB Lead Form
• Passing real fingerprint (IP, GEO, Device, User-Agent)
• Compatibility with Keitaro / Voluum
• At least 1 basic white-page template
🔐 3. Contact validation
• Email (verification via MX and SMTP ping)
• Phone (format + API for OTP verification — optional)
• IP-GEO compliance check
• Anti-fraud filter (blacklist/whitelist IP, email, GEO, UA)
🤖 4. Auto-login emulation
• Opening the broker's autologin link via server
• Emulating browser session (Puppeteer / Playwright)
• Inserting real fingerprint
• Preloader (1–2 seconds delay before redirect)
🔁 5. Replay Engine
• Loading CSV with the lead database
• Emulating repeat traffic (timers, proxies, fingerprint rotation)
💳 6. SaaS Billing & License
• Generating license keys
• Restrictions by: number of domains, traffic, sources
• Billing via crypto gateway (Cryptomus / NowPayments)
• Subscription and license management panel (admin)

2. I have experience working with Puppeteer, specifically writing scripts for fraud.
3. To be honest, I don't fully understand the technical specifications, so I can't assess the entire project right now — we can discuss this in more detail.
4. Yes.
The deadline and cost are indicated approximately, based on what I understood from the task.
