Security
Every supplier is verified before they can trade.
Here is how we protect both sides of every transaction. From corporate identity checks to payment isolation.
KYB — Know Your Business
Before a company can list products or receive inquiries, we verify their legal identity. Corporate registration documents are checked against official government databases, tax IDs validated, and legal representatives confirmed via live video. Only Verified companies appear on the marketplace.
Document Vault
Sellers upload SGS inspection reports, assay certificates, certificates of analysis, and bills of lading directly to their listings. Documents are stored securely and shared only with verified buyers who have submitted an RFQ for that specific listing. No public document access.
Payment Security
Kupros never holds client funds. All payments flow directly between buyer and seller through standard banking channels: Letter of Credit or Wire Transfer. The money moves bank-to-bank, outside our platform. This eliminates counterparty risk with Kupros itself.
Data Isolation
Deal data, inquiry details, and negotiation messages are visible only to the involved parties. RBAC at the API and UI layer prevents cross-account data leakage. Every API endpoint validates user identity before returning data.
Infrastructure
Kupros runs on Vercel with PostgreSQL on Neon. All connections encrypted in transit via TLS 1.3. Authentication uses JWT tokens in httpOnly cookies, no client-side access to sensitive session data.
