Это статья о том, как отправить Flash криптовалюту, и в то же время у меня есть вопрос,
Это мой код Python, и ситуация выглядит следующим образом.
1. Генерируется смарт-контракт.
2. Транзакция отправляется.
3. Блоки подтверждают
4. Взимается ПЛАТА ЗА ГАЗ
Но это не помещается в кошельки
Кто-нибудь знает, в чем может быть причина?
