Which patter design fits best when managing different logic for different crypto currencies?

I'm working on a exchange project where each coin has its own logic implementations, such as transfer logic, balance logic, exchange rates logic, and so on. Can you recommend a pattern design to handle all this in a efficient, maintainable way? I'll have to add more coins later, so I want my code to be ready as much as possible. I'm working with spring boot latest and I know there are some patterns that work out of the box. If anyone can guide me in the correct direction, I'd appreciate it. Greetings
