Money transactions service

There is a simple transactions service. Implemented authorization via login and password. User can have several valets. Implemented transactions between wallets with 1.5% commission. Multiple currencies supported(BTC, ETH).

Project created for demo purposes, not ready for production usage.

Requirements

You need to implement a backend application that would allow users to transfer funds between wallets. On every transaction, the system will need to take a commission of 1.5%.

Create a relational database schema
Upon application start, the database should be populated with sample data (e.g several wallets that can be used to transfer funds between)
The system should support two currency: BTC and ETH
Create a REST endpoint that can be used to transfer funds
Provide a docker-compose.yml that can be used to run your solution by just doing docker-compose up

Tests

Disclaimer

I have problems with running tests in docker container, trying to resolve. For now, I run tests locally. There are only functional tests. I would need more time for unit tests implementation.
I use float for price. I think, it's not the best approach, but I think, it's out of scope for this task. I would use some specific doctrine type, or some php library for money processing.
For now there are no access tokens, I use email/password for authentication
