Sends a raw transaction with web3 v1.2.2, ethereumjs-tx v2.1.1, and Infura

sendRawTransaction.js

const Web3 = require('web3')
const Tx = require('ethereumjs-tx').Transaction

// connect to Infura node
const web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io/INFURA_KEY'))

// the address that will send the test transaction
const addressFrom = '0x1889EF49cDBaad420EB4D6f04066CA4093088Bbd'
const privateKey = new Buffer('PRIVATE_KEY', 'hex')

// the destination address
const addressTo = '0x1463500476a3ADDa33ef1dF530063fE126203186'

// construct the transaction data
// NOTE: property 'nonce' must be merged in from web3.eth.getTransactionCount 
// before the transaction data is passed to new Tx(); see sendRawTransaction below.
const txData = {
  gasLimit: web3.utils.toHex(25000),
  gasPrice: web3.utils.toHex(10e9), // 10 Gwei
  to: addressTo,
  from: addressFrom,
  value: web3.utils.toHex(web3.utils.toWei('123', 'wei')) // thanks @abel30567
  // if you want to send raw data (e.g. contract execution) rather than sending tokens,
  // use 'data' instead of 'value' (thanks @AlecZadikian9001)
  // e.g. myContract.methods.myMethod(123).encodeABI() (thanks @NguyenHoangSon96)
}

/** Signs the given transaction data and sends it. Abstracts some of the details of 
  * buffering and serializing the transaction for web3.
  * @returns A promise of an object that emits events: transactionHash, receipt, confirmaton, error
*/
const sendRawTransaction = txData =>
  // get the number of transactions sent so far so we can create a fresh nonce
  web3.eth.getTransactionCount(addressFrom).then(txCount => {
    const newNonce = web3.utils.toHex(txCount)
    const transaction = new Tx({ ...txData, nonce: newNonce }, { chain: 'mainnet' }) // or 'rinkeby'
    transaction.sign(privateKey)
    const serializedTx = transaction.serialize().toString('hex')
    return web3.eth.sendSignedTransaction('0x' + serializedTx)
  })


// fire away!
// (thanks @AndreiD)
sendRawTransaction(txData).then(result =>
  result
    .on('transactionHash', txHash => {
      console.log('transactionHash:', txHash)
    })
    .on('receipt', receipt => {
      console.log('receipt:', receipt)
    })
    .on('confirmation', (confirmationNumber, receipt) => {
      if (confirmationNumber >= 1) {
        console.log('confirmations:', confirmationNumber, receipt)
      }
    })
    .on('error:', error => {
      console.error(error)
    })
)

Same problem, sending a signed transaction using web3 1.0 to Kovan through Infura, I get the receipt so the node has accepted the transaction, but if this is happening to multiple users, seems like Infura is not broadcasting signed transactions in Kovan.
I can't see it in my other node, or in etherscan.

How to prevent replayProtection here.. i mean we can take the signed raw tx and broadcast in eth classic network provided the sending acc complies with the nonce and balance check?

I've been gettinig an error UnhandledPromiseRejectionWarning: TypeError: Tx is not a constructor with the latest version of ethereumjs-tx package until I updated the line 2 to: const Tx = require('ethereumjs-tx').Transaction

@Aldekein Thanks! Updated. What version of web3 are you using btw?

Would it be possible to see an example with a contract deployment as the transaction? Thanks!

updated version of this script. https://gist.github.com/AndreiD/675027abdaa885716ce2c5af16166510

Updated from @AndreiD's script. If someone could confirm that the updated gist works for them, that would be great.

Thank you @AlecZadikian9001 for the tip. Updated with comment.

Thanks @abel30567. Updated.

Hello, i get an error sendRawTransaction(txData).then(result =>
^

TypeError: Cannot read property 'then' of undefined

@EffMining What version of web3 are you on?

Encountered the same error as @EffMining, use web3 v1.2.2, ethereumjs-tx v2.1.1.
Also got error

function sendRawTransaction(txData) =>
                                   ^^
SyntaxError: Unexpected token =>```

@simplespy Sorry, that should be: const sendRawTransaction = txData =>

I am getting such an unhelpful error:
Error: Returned error: VM Exception while processing transaction: revert

It is driving me crazy. Does anyone have any ideas why this could be failing?

transactionData = myContract.methods.foo('bar');
gasPrice = await web3.eth.getGasPrice();
account = web3.eth.accounts.privateKeyToAccount(privateKey);
txCount = await web3.eth.getTransactionCount(account.address, 'pending');

rawTx = {
    nonce: web3.utils.toHex(txCount),
    gasLimit: web3.utils.toHex('800000'),
    gasPrice: web3.utils.toHex(gasPrice),
    to: smartContractAddressTreasury,
    value: fee,
    data: transactionData,
};

@acidic9 It's probably an error in smartContractAddressTreasury. Either it is a bug, or you may be passing the wrong data or in the wrong format.

@acidic9 I think you forget to encode the data like so transactionData.encodeABI()

Thanks guys. I think the issue was just that my gas limit was too low :/

I get the following error when trying to send a transaction over the kovan test network

error Error: Returned error: Invalid chain id.
