our call
Start with FraudNet — highest vibe code, weakest moat.
Eye4Fraud
Building a rule engine for fraud scoring in Cursor takes days, but Eye4Fraud's core value is financial insurance and global intelligence. AI cannot write checks to cover $5,000 chargeback disputes when a stolen card slips through custom rules.
you can rebuild
- Basic order risk scoring engine
- Rules-based transaction flagging (AVS, CVV, IP matching)
- Customer order review dashboard for operations staff
- Email notifications for suspicious order holds
- E-commerce platform webhook listeners for pending orders
what you lose
- 100% chargeback guarantee and financial reimbursement
- Cross-merchant network intelligence on stolen identity reuse
- Human fraud analyst manual review service
- Automated dispute handling and representation with banks
- Device fingerprinting database across thousands of stores
real moats
- Financial underwriting capacity to absorb chargeback losses
- Proprietary cross-merchant fraud graph and device telemetry
- Human analyst operations network for edge cases
open source escape hatches
- MaxMind minFraud Node API Apache-2.0
- MindsDB GPL-3.0
- PostHog MIT
FraudNet
Building a rule engine with MaxMind or Radar APIs takes a weekend, but you cannot replicate FraudNet's global network of shared fraud signals and device fingerprint intelligence. Without global transaction data across thousands of stores, custom AI models hallucinate or generate false positives that destroy legitimate conversion.
you can rebuild
- Rule-based transaction scoring engine (e.g., velocity checks, threshold limits)
- Order risk review dashboard and manual approval workflow
- Blacklisting and whitelisting by email, IP, shipping address, or BIN
- Basic geo-IP mismatch detection and address verification triggers
- Webhook alerts and automated order holding in Shopify or WooCommerce
what you lose
- Cross-merchant network intelligence tracking fraud rings across thousands of stores
- Proprietary device fingerprinting heuristics bypassing browser privacy protections
- Chargeback guarantee coverage options that shift financial liability away from you
- Real-time proxy, VPN, TOR, and residential botnet IP reputation databases
- Continuous machine learning model retrain cycles backed by global dispute feeds
real moats
- Cross-merchant consortium data linking malicious devices and emails across clients
- Proprietary device fingerprinting scripts resilient to modern privacy browsers
- Chargeback liability shifting and financial guarantee models
