Я создал токен ERC23 и развернул его на etherscan с помощью онлайн-компилятора солидности ремиксов, все выглядит хорошо, etherscan tracker показывает баланс 200 мил, однако, независимо от того, какой кошелек я использую, баланс показывает 0. Можете ли вы, пожалуйста, определить проблему? Ниже приведен точный код, который я использовал:
