Hi folks, because Ethereum blockchain eat whole SSD every few days, I must doing frequent cancel of GETH and backup of account. There is one flaw: At every backup event. all ETH are saved and all tokens (yes, I administered tokens) vanished completely. Is there someone who knows how way backup also Admin account for tokens ? Thanks Ivan

i have a question
i send transaction by code:
const contract = new web3.eth.Contract(JSON.parse(abi), '0x8e97ec7a54abf98ca7e008ff46a02f4bba0fdbc1', {gasPrice: '12345678', from: '0xc7c583f96abe8bc439eba964d7697dcaa5165204'});

// console.log(contract.methods);
contract.methods.balanceOf('0xc7c583f96abe8bc439eba964d7697dcaa5165204').call().then(console.log).catch(console.error);

contract.methods.totalSupply().call(function(err,res){

    if(!err){
        console.log(res);
    } else {
        console.log(err);
    }
});

// send token from contract address to anthoer address
// contract.methods.transfer('0xC8435dBCD3ebd0Cc78Fc4c12a115a4f0Cbdd8929', web3.utils.toWei('0.01')).send().then(console.log).catch(console.error);
var count = await (web3.eth.getTransactionCount('0xc7c583f96abe8bc439eba964d7697dcaa5165204'));
// count = 10;
console.log(count);
var transferAmount = 10000000000000000000;
var gasPriceGwei = 3;
var gasLimit = 3000000;

var bool = contract.methods.transfer("0xA17Dfa994be3abdF3a70Fb664BD47dF4b95C8d4e", transferAmount).send({from:'0xc7c583f96abe8bc439eba964d7697dcaa5165204'}).then(console.log);

var rawTransaction = {

    "nonce": "0x" + count.toString(16),

var tx = new Tx(rawTransaction);

tx.sign(privKey);
var serializedTx = tx.serialize();

web3.eth.sendSignedTransaction('0x' + serializedTx.toString('hex'), function(err, hash) {

Hi- I am not sure if this is the right channel to ask- Please correct me if I should post similar queries elsewhere. So, I am an experienced SDE,and after investing some time, I believe I do have good familiarity with Solidity/Ethereum. I want to showcase both working code and a writeup on the same, which would primarily be of interest to those who might be keen to engage me professionally. With that in mind, what is a critical/important area that you, as an Engineer, sorely feel that better tutorials/code examples are definitely due?
