Payment Processing Infrastructure
The client approached us with the task of creating a proprietary cryptocurrency payment widget that can be embedded on third-party websites and accept cryptocurrency without redirects. Key requirements: simple integration, support for popular cryptocurrencies, and security at all transaction stages.
Stack
Rust
Node.js
PostgreSQL
Kafka
gRPC
What We Did
- Developed the widget.
- Implemented backend logic for invoice creation, wallet address generation, and real-time payment status tracking.
- Supported major cryptocurrencies (Bitcoin, Ethereum, USDT, Litecoin) with expansion capabilities.
- Integrated WebSocket for displaying transaction status to the user without page reloads.
- Ensured security: data encryption, address validation, protection against request tampering
Result
The client received a payment widget that can be integrated into partner websites in 5 minutes. The widget became part of their ecosystem, enabling scalable acceptance of cryptocurrency payments without complex setup and providing control over UX, independent of third-party solutions.
