I have almost searched all of duplicate questions but not getting any help.
Can someone please point out what is wrong why I'm getting error insufficient funds for gas * price + value, I double check and I have enough ether in my test account.
Some console output:
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

gasandgasPrice? Have you tried including a leading0xin the private key? My guess would be that somehow the transaction is being sent "from" the wrong account (which would mean something is wrong with the private key).0xin front of private key and now it is working, thanks man... estimate Gas is36210, could you please put a answer with detail what is0xand where should I need to use it? should I include it in beginning of transfer tokens?Gas Limit, should I includegasLimitoption in my transaction object orgasoption is okay ?
