Challenges

XXX is an ERC-20 token, and there are more than 10 cryptocurrencies that use this same Ethereum infrastructure. However, the ERC-20 infrastructure is getting more expensive as the load grows. So one challenge for our client is to integrate the Binance Smart Chain, which will allow XXX cryptocurrency to be transferred between users for a much lower commission.

The world of decentralized finance is actively developing and has its own characteristics. There are many ready-made solutions today, but there is still a lot to develop from scratch. To do this, we need to understand how to properly calculate commissions, how to avoid budget losses, how to properly integrate with all third-party services, and how APIs work — and we need to be sure that everything can be scaled.

The application infrastructure must be ready for integration with another blockchain so the client doesn’t lose money on commissions and users are comfortable using the application.
