Enterprise-Grade Features

Built with Go microservices to handle high-volume financial transactions with precision and security.

PCI-DSS Compliant

Secure card tokenization service with AES-256-GCM encryption and automatic key rotation (90 days).

Microservices Arch

Decoupled services for Auth, Tokenization, and Ledgering communicating via high-performance gRPC.

Multi-Currency

Native support for USD, EUR, and MAD with real-time conversion and daily settlement batching.

Developer First

Idempotency keys, rate limiting, and webhooks built-in for a robust integration experience.

Auth & Security

JWT-based authentication, Role-Based Access Control (RBAC), and per-merchant API keys.

Ledger Integrity

Double-entry accounting principals ensuring financial data consistency and audit trails.

Distributed Systems Design

  • API Gateway (HTTP/REST) handles routing and rate limiting.
  • gRPC for low-latency internal service communication.
  • Asynchronous processing via Event-Driven architecture.
  • Redis for distributed caching and idempotency locks.
  • PostgreSQL with ACID compliance for transactional data.
