Crypto-to-crypto invoicing



Numerous cryptocurrencies, multiple wallets, and various tokens put a heavy load on the system.

Our approach to solve performance problems:

  1. We monitored performance in real-time using dedicated tools (like celery-flower),
  2. Then, we identified bottlenecks,
  3. Last, we reduced the number of tasks (task = request sent to the system); divide big tasks into smaller ones; increased the number of concurrent processes;
  4. If needed, we repeated steps 1,2,3 until we have found a perfect solution.

Now, the application works quickly and flawlessly, no matter how much data it has to process.

Real-time portfolio overview

The user has to get a real-time overview of their assets. Every transaction is valued in your local currency at the exact market price at the time of occurring. For us, it means that we have to follow live all networks like Polygon, Bitcoin, Ethereum, and Binance Smart Chain. We used Bitquery Blockchain API to support the software and make it simple to work with multiple networks.

Solution natively integrates token-based payments and is an all-in-one solution combining essential accounting features and invoicing. Software is developed in a way to provide reliable accounting services without storing any personal data.
