после прочтения многих постов я не могу найти вопросы об этом смарт-контракте, который компилируется, но мне кажется, что я что-то упускаю из-за наследования и абстрактного контракта.

* Import abstractions into the '.sol' file that uses them instead of deploying them separately.
* Contracts that inherit an abstraction must implement all its method signatures exactly.
* A contract that only implements part of an inherited abstraction is also considered abstract.
