CryptoWrap

CryptoWrap is a payment gateway/processor architected for secure, reliable, and seamless cryptocurrency transactions. Providing a unified interface for both inbound and outbound payments. The project prioritizes simplicity and ease of integration, offering a lightweight and fast solution that operates as an extensible wrapper (API layer) for various blockchains.

Coins

  • Monero
  • Litecoin

Features

  • HTML page for accepting crypto payments in 3 different modes:
  1. WebSocket (fastest, requires .js, not implemented yet)
  2. HTTPS polling (reliable, requires .js, default, implemented)
  3. No-JavaScript (requires refresh html tag and backend logic, not implemented yet)

You can use your own customised HTML template using same API endpoints.

  • Accept, store and send coins via isolated virtual accounts.
    For systems with multiple users, where funds must be safely separated and managed.

  • Deposit tracking with multi-transaction support
    A deposit is a mechanism for accepting crypto payments in a single logical transaction with a dynamic amount. The system detects inbound funds and tracks progress until the deposit is finalized. It supports both single and multiple partial transactions — for example, during Monero's 10-confirmation lock user can send multiple transactions, all of which are detected and aggregated. Other currencies may finalize deposits earlier (fewer confirmations), but the system handles this seamlessly since detection is confirmation-agnostic. The deposit status transitions from waiting → detected (mempool/pool) → confirmed (all funds confirmed), returning all relevant txids and the total received amount. With multiple txs, the returned confirmation count is the minimum across all transactions.

Technology Stack

This project is built using a robust and modern technology stack, orchestrated within Docker containers for easy deployment and scalability:

  • Reverse Proxy/Load Balancer: Nginx (default) / Nginx + HAProxy
  • Backend: Rust (Axum framework)
  • API Documentation: Swagger UI and OpenAPI.json
  • Database Interaction & Migrations: Sea-ORM
  • Database: PostgreSQL
