Security model
Security takes precedence over convenience.
Every layer of NexumPay — authentication, authorization, transactions and infrastructure — is built to the same standard, not just the parts customers can see.
Layered by design, not by accident.
Authentication, authorization, transaction integrity and infrastructure security are separate layers that each have to hold — not one control standing in for all four.
Security layers
Authentication
- Access tokens
- API keys
- Session validation
Authorization
- Role-based access control
- Business-level roles
- Granular permission management
Transaction security
- OTP verification
- Transaction signatures
- Full audit trails
Infrastructure
- HTTPS encryption everywhere
- Secured API communication
- Continuous database logging
Building an integration? The same authentication model — wallet secrets and scoped API keys — is covered step by step on the Developers page.
