Получение ошибки недостаточно средств на газ * цена + стоимость

Я почти обыскал все повторяющиеся вопросы, но не получил никакой помощи. Может кто-нибудь указать, что не так, почему я получаю сообщение об ошибке insufficient funds for gas * price + value, я дважды проверяю, и у меня достаточно эфира на моей тестовой учетной записи.

Некоторый консольный вывод:

    console.log('web3 version:'+ web3.version);
    web3.eth.net.getId(function(err, res){
        console.log("Net: "+res);
    });
    web3.eth.net.getNetworkType(function(err, res){
            console.log("getNetworkType: "+res);
    });
    web3.eth.getBlockNumber(function(error, result){
        console.log("Block Number: "+result);
   });


    web3 version:1.0.0-beta.34
    Block Number: 3085927
    291 Net: 3
    getNetworkType: ropsten

Каковы значения gasи gasPrice? Вы пытались включить ведущий 0xв закрытый ключ? Я предполагаю, что транзакция каким-то образом отправляется «с» неправильной учетной записи (что означает, что что-то не так с закрытым ключом).
@smarx, ты спас мне жизнь :) Я включил 0xперед закрытым ключом, и теперь он работает, спасибо, чувак ... оцените Газ 36210, не могли бы вы дать ответ с подробным описанием, что это такое 0xи где мне нужно его использовать? я должен включить его в начало передачи токенов?
Теперь я вижу свою транзакцию и в сети ropsten :)
Еще одна вещь, когда я отправляю эти токены с помощью myetherwallet, есть поле Gas Limit, должен ли я включать gasLimitопцию в свой объект транзакции, или gasопция подходит?
Кто будет платить за газ? отправитель токена или получатель токена?
Добавил ответ. Газ всегда оплачивается со счета, с которого совершается транзакция. Итак, отправитель токена в данном случае.
gasи gasLimitявляются просто псевдонимами друг для друга. Вы можете использовать любой из них.
Отлично, теперь все в порядке :) и спасибо за ваше время.

В комментариях к вопросу вам нужно добавить a 0xв начало вашего закрытого ключа. web3.jsчасто требует этот префикс, поэтому он знает, что строка, которую вы предоставляете, является шестнадцатеричным представлением последовательности байтов (например, закрытый ключ).

Ух ты! Спасибо, спасибо за этот простой лакомый кусочек. Этот «0x» стоил мне часа или около того и многих поисков решений.
