Casi he buscado todas las preguntas duplicadas pero no he obtenido ninguna ayuda. ¿Puede alguien señalar qué está mal? ¿Por qué recibo un error? insufficient funds for gas * price + valueVerifico dos veces y tengo suficiente éter en mi cuenta de prueba.

Algunos resultados de la consola:

    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

¿ Cuáles son los valores de gasy gasPrice? ¿Has intentado incluir un líder 0xen la clave privada? Supongo que de alguna manera la transacción se envía "desde" la cuenta incorrecta (lo que significaría que algo anda mal con la clave privada).

Muhammad Shahzad

@smarx me salvaste la vida :) Lo incluí 0xdelante de la clave privada y ahora está funcionando, gracias hombre... estima que Gas es 36210, ¿podrías poner una respuesta detallada sobre qué es 0xy dónde debo usarlo? ¿Debo incluirlo al comienzo de los tokens de transferencia?

Muhammad Shahzad

Puedo ver mi transacción ahora también en la red ropsten :)

Muhammad Shahzad

Una cosa más cuando envío estos tokens con myetherwallet, hay un campo Gas Limit, ¿debo incluir gasLimitla opción en mi objeto de transacción o gasla opción está bien?

Muhammad Shahzad

¿Quién pagará el precio del gas? ¿emisor de tokens o receptor de tokens?

usuario19510

Se agregó una respuesta. La gasolina siempre se paga por la cuenta que realiza la transacción. Entonces, el remitente del token, en este caso.

usuario19510

gasy gasLimitson solo alias el uno para el otro. Puedes usar cualquiera de los dos.

Muhammad Shahzad

Genial, todo está bien ahora :) y gracias por su tiempo.

Según los comentarios sobre la pregunta, debe agregar un 0xal comienzo de su clave privada. web3.jsa menudo requiere este prefijo para que sepa que la cadena que está proporcionando es una representación hexadecimal de una secuencia de bytes (como una clave privada).

¡Guau! Gracias, gracias por ese simple dato. Ese '0x' me costó una hora más o menos y mucha búsqueda de soluciones.
