Crypto Payment Gateway

I'm seeking an experienced developer to create a comprehensive cryptocurrency payment gateway for merchants. This system should allow easy integration with their stores and online platforms, enabling them to accept a wide variety of cryptocurrencies.

Key requirements include:
- Support for Bitcoin, Ethereum, Solana, Tron, and other tokens on major networks
- Compliance with AML, KYC, KYB, KYT, and MiCA regulations
- Ability to exchange cryptocurrencies among different tokens
- API settings
- Advanced Admin Panel with ability to manage as many things as possible
- Hold, management of transactions with high AML risk
- User-friendly features such as:
- Transaction history
- Deposit and withdrawal options
- Account activity logs
- Adjustable settings
- Automat conversion of cryptocurrencies after payment
- Handling partial transactions
- Employee accounts management

The whole software must be fully scalable so that over time it can handle the growing number of users and transactions.

It is difficult to list all the functions of the system due to its complexity, so I have listed the main ones. Remember that the main functions consist of many sub-functions and their settings.

Ideal candidates will have:
- Proven experience in developing secure payment gateways
- In-depth knowledge of cryptocurrency and blockchain technology
- Familiarity with regulatory requirements in the crypto space
- Strong skills in backend development and database management
