invalid sender error when trying to send signed transaction

+1 vote

I'm trying to sign transaction and send it to remote node, but I keep getting this error: UnhandledPromiseRejectionWarning: Error: Returned error: invalid sender

This is how I perform signing and then sending actions:


var keyPair = {

address: '0x413671Ef1633C4e31D07c4D36C92109792133C8a',

privateKey: '0x6ade95688cb8c16a6e6543505a995a3ad37fb93404189228d5f2ed690008a2ce' //also tried without prefix


var Deployer = {

TxBuilder: function() {

var signedTx;


web3.eth.getTransactionCount(keyPair.address).then(function(res) {


nonce: web3.utils.toHex(res + 1),

from: keyPair.address,

to: smartContractData.address,

data: `some encoded data for tx`,

gas: '4000000',

gasPrice: web3.utils.toHex('5000000000'),

gasLimit: web3.utils.toHex('4000000'),

chainID: '2487' // chain ID set to a genesis.json

//v: 28 also tried v: 27, v: chainID, v: chainID * 35 + 2

}, keyPair.privateKey).then(signedTx => {


web3.eth.sendSignedTransaction(signedTx.rawTransaction).on('receipt', console.log);



} catch(error) {

console.error('Error while sending signed tx: ' + error);






And here is the error I'm getting:

I'm able to sign the transaction, but I just can't send it. Also I can call / send transaction to any method in any smart contract on the same private network from the very same account via MyEtherWallet (after connecting to the node of course). The problem is that I just can't do the same via web3.


I'm using:
- web3 1.0.0 36 beta

Any help with this is much appreciated, thank you!

Hi, i had the same error and i solve this by fix the config

If you are the owner of the network
When you want to power a network, you must to define the network ID in option in command line for geth to perfom network, it must be equal with chain ID in config.
after this in you transaction object you also must to specify chainId.

And it error should be solves

Thanks bublig737, will try it out.

Hey @bublig737. Did you mean like this:

geth --datadir ./myDataDir --networkid 1114 console 2>> myEth.log
