Any number of operations can be defined by the service provider,
howbeit, the payment operation with the key payment will always be executed at the end of the operation
chain if the user decides to go through with the payment. Therefore,
the service provider is obliged to provide an implementation for the payment operation.
Additionally, the Georgian Tetri is assumed to be the default currency.
