if the transaction only handles one repository, you can use begin & comit, but if you need to perform transactions for more than one repository function, you can handle it in the usecase by defining a new repository transaction.

type (
	UseCases interface{
		ExampleImpl(context.Context)error
	}

	usecase struct{
		repo Repositories
		conn sqlx.DB
	}
)

func NewUsecase()UseCases{
	return &usecausecase{}
}

func(uc *usecase)ExampleImpl(context.Context)error{
	//create begin from usecase.conn

	// defer rollback 

	//call repository function
}`

I don't know if this method is clean or not, but at least it solves the problem.
